USB-C and Thunderbolt gear confirmed for Steam Deck

Basic multi-display USB-C output works with the Steam Deck (used to drive 3 monitors for a Batocera/VPX pinball cabinet setup), but a specific software issue disconnects one of the three displays (the DMD screen) as soon as the frontend finishes loading.

A Steam Community post confirms the dock's dual-display output works reliably with the Steam Deck.

Per community reports, the dock can operate over the Steam Deck's 10Gbps USB-C connection, but performance is severely limited: Ethernet does not work, and most of the dock's USB ports require PCIe passthrough, which the Steam Deck's controller doesn't support.

Initially failed to work with the Steam Deck at all (reported as completely non-functional), but a Valve SteamOS update released April 26th made it fully functional — video, Ethernet, and data all work now.

A Hacker News commenter debugging USB-C hub reliability reports the SD5750T "just works," and specifically names using it on their Steam Deck most of the time.

A personal blog documents this dock working nicely with the Steam Deck in docked mode, correctly driving a 3440x1440p ultrawide monitor and Gigabit Ethernet at rated speed.

Confirmed working via the HDMI port (video + charging). The secondary USB-C DP output on the dock does not work with the Steam Deck, since exposing a DP port there requires Thunderbolt/USB4 host support the Deck lacks.

Per community reports, this dock does NOT drive native video output on the Steam Deck — it only works through DisplayLink software mode, which requires disabling SteamOS's read-only filesystem and manually compiling kernel modules, a setup that breaks with every SteamOS update.

A user chaining AR-glasses hardware names both the HP G2 (2UK37AA) and G4 (4J0A2AA) docks as working well with, among other hosts, a Valve Steam Deck.

Listed by UGREEN's own regional store as compatible with the Steam Deck, as part of a broad list of USB-C devices — not a device-specific technical claim.

Confirmed working perfectly with the Steam Deck, though the user notes this may be specific to Desktop Mode using the X11 windowing system rather than the default Gamescope/Wayland session.

Confirmed via a blog post naming the Steam Deck explicitly among the docks the author had success with.

A user mentions using this dock with a Steam Deck alongside a Framework laptop and MacBook Pro.

A user reports getting 2x 1440p@60Hz displays working with the Steam Deck through this dock, good for basic productivity.

A user confirms this dock (40AY) works fine with the Steam Deck, noting cable quality matters for reliable video output.

A Steam Deck user reports that setting the refresh rate to 40Hz in Desktop Mode caused connected monitors to stop displaying — reverting to the default refresh rate fixed it. The same user could not get both monitors to output at 2560x1440 simultaneously.

Confirmed working for months, then a Steam Deck software update caused DisplayPort output to stop being detected — resolved by a full restart (not sleep/wake) plus a full battery discharge/recharge cycle, not by any dock-side fix.

A Steam Deck user reports the dock's mouse, keyboard, and headphone ports are recognized correctly, but the connected monitor shows no signs of being detected.

A user reports the dock works with the Steam Deck except for the DisplayPort outputs — only the HDMI port outputs video.

A user reports the Steam Deck works flawlessly through this dock, naming the exact port layout (3x USB-A, 2x USB-C, Ethernet, 2x DisplayPort, HDMI).

Confirmed via a community-designed 3D-printed dock enclosure that integrates this exact hub for Steam Deck use, requiring a 90-degree right-angle USB-C adapter to relieve cable strain.

A Steam Deck bug report describes the dock's keyboard and mouse suddenly going unrecognized after a SteamOS update, having worked correctly the day before.

Confirmed via a community-designed 3D-printed dock that integrates this exact hub for Steam Deck use, requiring a 90-degree right-angle USB-C adapter.

A user reports using this dock with the Steam Deck, getting 144Hz on a secondary monitor but only 100Hz on the primary one.

A user with the Titan Ridge (JHL7440) variant of this dock reports full fallback to USB-C DP Alt Mode, driving a Steam Deck at 3440x1440@75Hz alongside working peripherals.

A user mentions using this dock with a Steam Deck alongside a Framework laptop, with video output working.

A user confirms this dock works with the Steam Deck, including driving two DisplayPort displays, but requires switching to Desktop Mode before connecting and letting it initialize before plugging in the USB-C cable.

An HP support community member documents a specific workaround: monitors stop being detected on hot-plug, but leaving the dock connected through a full cold shutdown and reboot of the Steam Deck restores video — the ACPI/hot-plug handshake fails, but the boot-time device tree mapping succeeds.

Confirmed via a community-designed 3D-printed enclosure (v2 design) that converts this exact hub into a Steam Deck dock.

A user reports having used this on their Steam Deck and it works just fine, though Belkin's own support answer notes the dock has not been officially tested with Steam Deck.

A Steam Deck user names this dock specifically as their portable choice, in contrast to a JSAUX dock they keep at their desk but rarely connect.

A user reports occasional use for power and Ethernet, but describes it as "prohibitively unreliable" long-term — it works initially but drops out after intensive/sustained use, likely due to insufficient cooling.

Named directly in the product title on UGREEN's own US store: "...Compatible with Mac M1, M2, M3, iPad, iPhone 16 Pro/Pro Max, Steam Deck."

A Steam Deck user reports the external monitor shows 'HDMI no signal' when connecting through this hub in Game Mode. Switching to Desktop Mode and manually setting the monitor's refresh rate to 120Hz gets the connection working.

Confirmed via a community 3D-printed dock/stand design that mounts this exact hub (201048-BLK) to the Steam Deck for video and Ethernet output — no direct user review, but the maker effort implies working functionality.

A Steam Deck user reports the dock charges the console normally, but the monitor is never recognized — the Thunderbolt 3 controller (Alpine Ridge-class) has no fallback path to the Deck's plain USB-C/DP Alt Mode video.

A user reports the dock, which previously worked out of the box with their Steam Deck, later required DisplayLink software mode to get Alt Mode video output working again — the underlying video path is not fully native.

Listed explicitly as a supported device on Baseus's own product page, though no independent hands-on report was found to confirm real-world performance.

A user reports this dock can charge the Steam Deck while playing on a TV, though the SD card slots don't seem to work with the Deck.

A user reports regularly using this hub with the Steam Deck on different displays, alongside the official Valve dock.

The retailer's own product page notes: 'For the best experience with Steam Deck, connect it to the wall charger when using with the hub' — implying the dock alone may not reliably power the console under load.

A user names this dock among the few dual-video docks confirmed to work with their Steam Deck.

Anker's own blog names the Steam Deck explicitly, describing the hub as a way to add a monitor, keyboard, mouse, and Ethernet to the console for a desktop-style setup.

A user confirms this adapter works fine with the Steam Deck after a firmware update, having previously needed to restart the Deck for it to be recognized.

A user reports daisy-chaining this hub with other USB-C hubs and a Steam Deck OLED, with power fed through only one hub — described as "working fine" so far, though the long-term safety of this unconventional multi-hub power setup is unverified.

A Coolblue customer review confirms plug-and-play operation with the Steam Deck, without further detail on which of the dock's outputs were tested.

Listed by the manufacturer's own product page as a compatible device.

The manufacturer's own product page confirms Steam Deck compatibility (explicitly not compatible with Nintendo Switch), provided each connected display supports HDCP.

A user resolved intermittent HDMI resolution issues with this hub on a Steam Deck by switching to a higher-wattage USB-C power supply (65W); the underlying power supply, not the hub, was the root cause.

A user confirms this dock runs "perfectly plug and play" with the Steam Deck after testing.

A user reports the Steam Deck works "flawlessly" as a desktop workstation with dual monitors through this dock.

A user recommends this dock highly for Steam Deck use, contrasting it with the Surface Dock 2 which only works with Surface devices.

A community post lists this dock as part of a long-term stable multi-device setup that includes a Steam Deck, alongside a Surface Laptop Studio, an Intel NUC, and MacBook/Asus laptops.

A user reports the dock works with the Steam Deck including fast charging (no "slow charger" warning), Ethernet, and additional DisplayPort outputs.

An IT admin reports using this dock reliably at work and at home, including as a simple DIY portable workstation dock for their Steam Deck.

A Legion Go community post names this hub as suitable for the Steam Deck, ROG Ally, Legion Go, and MSI Claw, without device-specific technical detail.

A user reports this adapter works as intended for people with a modern USB-C monitor and sufficient PD charging for the Steam Deck.

Falls back to the 10Gbps USB 3.2 connection Steam Deck supports, but performance is severely limited — Ethernet doesn't work and most USB ports won't work since they require PCIe passthrough, which Steam Deck doesn't support.

The dock and video/data/charging work fine. Mounting the internal NVMe drive on SteamOS requires manually reassigning file ownership from root to the deck user via the terminal (Konsole) after formatting to EXT4 — JSAUX's own script doesn't always avoid this.

Stable enough on Steam Deck that the community has designed 3D-printable dock stands specifically for this hub. Its DP Alt Mode handling supports high refresh rates, though the firmware sometimes hard-caps ultrawide monitors at 100Hz instead of the advertised 144Hz.

Demonstrated on video driving a competitive game on an external monitor at 1080p/144Hz via Steam Deck, indicating clean EDID handling.

Compatibility claim sourced from a retailer/price-comparison listing naming this exact SKU alongside Steam Deck, ROG Ally, and Legion Go; no independent community report (Reddit, forums) was found to corroborate real-world use.

Reported to hold a clean 4K@60Hz signal on Steam Deck. Independent reports document the aluminum chassis suffering heat-induced HDMI controller failure after days of sustained use with higher-TDP devices — avoid long continuous sessions.

Strong evidence: the community has produced CAD-designed dock mounts built to this exact hub's tolerances specifically to house the Steam Deck.

Recommended in the community-maintained Steam Deck Guide on GitHub for its clean, thermally stable output. Reserves 15W internally, so using the stock 45W charger leaves less headroom for the console — a higher-wattage charger avoids the deficit.

Handles power delivery and resolution correctly, but its short-cable dongle form factor creates a cantilever on Steam Deck's top-mounted port; the community has needed 3D-printed physical supports to prevent long-term stress on the console's USB-C solder joints.

The hub's flush-mount single USB-C connector is physically designed for MacBooks; users route around it on Steam Deck with a USB-C extension cable, at which point data/video negotiate normally.

Manufacturer-confirmed driver-free compatibility. Note the dedicated 10Gbps USB-C data port is data-only — it does not carry video or charging.

Named for this exact SKU in a distributor catalog listing (alongside Steam Deck, ROG Ally, Legion Go, MSI Claw); no independent community confirmation found.

Manufacturer confirms compatibility for Steam Deck. Video output is capped at 4K@30Hz due to bandwidth arbitration with the hub's 10Gbps data ports.

Sourced from a single retailer product page with vague "and more" phrasing rather than a technical or community source — treat this confirmation as weak.

Compatibility list from a single distributor spec sheet, naming Steam Deck and ROG Ally alongside major desktop/mobile OSes.

A Steam Deck user reports the hub works great overall, though power delivery comes in slightly lower than expected — likely due to the hub's own power consumption.

Confirmed via a community-designed 3D-printable Steam Deck stand built specifically to be compatible with this hub.

Named on the retailer's "Stable Driver Certified" compatibility list for Steam Deck. This is a legacy design; likely capped at 4K@30Hz given the HDMI controller generation.

UGREEN's own product page describes a two-position aluminum stand fitted specifically to Steam Deck (OLED), ROG Ally (X), and Legion Go.

CalDigit support confirms it works via USB 3.2 Gen 2 fallback (single external monitor through DP Alt Mode), but the hub's 60W cap triggers a "slow charging" warning under heavy load.

Verified through the seller Q&A rather than a review: confirmed to charge through Valve's official Steam Deck dock in a daisy-chain topology, and to recover display output cleanly after sleep/wake (S3) cycles without a black screen — a common failure point for cheaper hubs on SteamOS.

Manufacturer confirms Steam Deck compatibility, with the caveat that every display link in the chain must support HDCP or the picture will not render (a SteamOS/Linux handshake quirk, not a hub defect).

A minimalist travel hub with a legacy HDMI 1.4 controller, hard-capped at 4K@30Hz. Fine for desktop use at 1080p/60Hz, but the 30Hz ceiling introduces noticeable input lag at higher resolutions in games.

A Reddit user reports this dock outputs video over HDMI to the Steam Deck, but the connection typically stops working if an additional USB peripheral (like a wireless mouse dongle) is plugged in — power draw appears to be the limiting factor.

Retailer FAQ explicitly names Steam Deck (desktop mode) and MacBook Air/Pro as compatible. Passive DP 1.4 cable — no protocol conversion, so the compatibility risk is inherently low compared to active adapters.

"I dock my Steam Deck... uni." — confirmed as the DisplayPort cable used in a cloud-gaming dock setup.

Official Plugable documentation names this exact hardware family: "Windows and Linux based hand-held consoles like the Steam Deck, ROG Ally, and Legion Go include drivers." Linux hot-plug bug documented separately: on Pop!_OS/Ubuntu, connecting after boot or connecting the network cable late can leave the link permanently undetected or fall back to 100 Mbps until reboot.

"If you use the Apple USB C to 3.5mm headphone adapter, the onboard mics will still function even when outputting to your headphones" — unlike most USB-C DACs, this one does not fully hijack the audio routing away from the Deck's built-in microphones.

Negative evidence: "I tried the ifi go link but there was a lot of hiss and pop when navigating the menus of the SD (which quickly becomes annoying)" — audible electrical noise triggered by basic UI navigation.

Negative evidence: "A 'why doesn't this work' dock: Cable Matters 201046... not the steam deck" — the hub fails to process Multi-Stream Transport (display daisy-chaining) with the Steam Deck despite working on HP docking stations.

Enabling VRR above a 60Hz base refresh rate causes severe flickering and display corruption on Steam Deck — stable operation caps at 1080p@60Hz with VRR active; higher refresh rates work fine only with VRR disabled. Also, both USB-C cables must be connected simultaneously to reach full 144Hz and full brightness — powering it from the Deck alone caps brightness at roughly 80%.

Works standalone, but a dual-monitor MST setup via the official dock is unreliable — only one of the two monitors gets detected at a time.

No USB-C Power Delivery — video works but the Deck won't charge while connected.

A Steam Deck LE OLED could not reliably power this monitor over a single USB-C cable in community testing — the internal power management restricts passthrough charging enough that a static 5V profile fails to sustain the monitor's draw under load.

Its power management circuitry cannot sustain a positive charge state on a Steam Deck under real gaming load — the passthrough profile is too weak against the SoC's draw, resulting in a documented ~1% battery loss every ten minutes of connected use.

A Newegg listing for the MQ16FC names Steam Deck, ROG Ally and Legion Go explicitly as compatible devices.

Despite marketing implying otherwise, the monitor has zero bidirectional Power Delivery passthrough capability — it draws power for its own battery/panel but cannot forward any of it to a connected handheld, which will drain its battery during extended play regardless of connection.

Reaching 100% brightness requires the separate Espresso Charge battery pack — the Deck alone can't supply enough power.

Reaching 4K@240Hz requires manually setting the monitor's USB hub speed to 2.0 (from the default 3.2) to free up enough DisplayPort bandwidth.

Mixed reports — works for some users, others report compatibility issues.

Does not work as a power source — a Reddit comment notes the XG349C's USB-C output is not enough to power a laptop or Steam Deck.

A bug report on the official ValveSoftware/gamescope GitHub tracker documents both the 27GP850-B and the Steam Deck's built-in display going black in Gaming Mode.

A second monitor daisy-chained via DisplayPort MST isn't detected — works fine on Windows, but SteamOS doesn't recognize the chained display.

Works, though the 32-inch size looked oversized paired with the Deck's small form factor.

The 'Smart Size > 1:1' scaling option needed for the correct aspect ratio is oddly disabled while the Steam Deck is connected.

Confirmed working correctly running Windows 11 or Linux on the handheld, outputting the 32:9 ultra-wide resolution efficiently without major issues.

90W USB-C Power Delivery, confirmed sufficient for a Steam Deck OLED.

The USB-C input is intermittently not detected until switching cables; enabling VRR causes a permanent black screen (works fine over Thunderbolt without VRR).

Community members specifically single out this monitor as an excellent Steam Deck pairing, citing the real bidirectional USB-C charging as the key differentiator over cheaper portable panels.

Some users get a 'device does not support DP Alt mode, please install the latest driver' error either directly or through a dock — others report it working fine.

The USB-C downstream KVM delivers mouse, keyboard, 15W charging, video and audio over one cable, though the 15W charging is modest.

DisplayPort Alt Mode video works, but there's no Power Delivery at all on the USB-C port — can't run off a single cable.

The USB-C port used for the KVM function gets disabled after a period of use, breaking the connection.

Tested successfully in a triple-screen productivity/display setup, proving good compatibility with the dock structure of the handheld.

Touch input is wildly inaccurate — keyboard and mouse work normally.

Works as an external display, but frequently shows a blank screen unless using the exact OEM USB-C cable; simultaneous charging is highly problematic.

Functions effectively as a direct dock replacement, letting users bypass standalone hubs entirely with a single cable.

Mixed reports — the screen cuts out or stays black for some users at 5120x2160 over USB-C, while others report it working fine.

Confirmed to handle the Deck's forced 40Hz output smoothly.

The monitor's NVIDIA G-Sync Ultimate module has zero AMD FreeSync support, so an AMD-APU handheld like the Steam Deck will display video fine but gets no VRR at all — expect tearing without it.

Does not reliably work after resume — a Reddit user reports the Steam Deck stays docked and charging but the P2422HE shows nothing over HDMI, and neither a restart nor sleep/wake fixed it.

Community members confirm the KVM button and single-cable USB-C dock work with a Steam Deck, but consistently report a persistent "low wattage charging" warning since the monitor cannot fully power the device under load.

The monitor's 90W USB-C downstream port was successfully tested connecting to and charging a Steam Deck.

Confirmed working by the community when connected via a standard USB-C dock as the video source. Requires a genuine 10Gbps-rated USB-C cable — dropping to a 5Gbps connection removes 10-bit HDR (P010) support at 4K60 and forces more compressed capture formats. If the passthrough signal to the monitor triggers Display Stream Compression, the capture feed can go black, requiring a lower resolution/refresh on the source.

AVerMedia's own product selector tool explicitly lists the GC553G2 as compatible with Steam Deck.

A documented EDID handshake bug causes complete audio silence over HDMI — SteamOS reads the card's default EDID as "no speakers" and stops sending audio. Fixing it requires running Elgato's 4K Capture Utility on a Windows PC first to force an "Internal EDID" profile that declares audio capability.

A Reddit user reports buying the Live Gamer EXTREME 3 specifically to capture their Steam Deck.

Does not work reliably — a Reddit user reports the Live Gamer Mini does not support refresh rates above 60Hz, while the Steam Deck defaults to 90Hz.

A Reddit user confirms using the original ShadowCast to stream their Steam Deck in 1080p to a laptop.

Genki's own setup guide instructs plugging the ShadowCast 2 into the HDMI port of the Covert Dock 2 to capture a Steam Deck.

A Reddit user recommends the SeeMo to route Steam Deck video to an iOS device as a monitor.

Does not work in Gaming Mode — an official ValveSoftware/SteamOS GitHub issue documents the Steam Deck's screen going black when the BU113 is connected, with mpv showing a black window and reporting "No Video."

A YouTube Short states the Callisto Protocol footage on Steam Deck was captured using an external NZXT Signal HD60 capture card.

A YouTube video shows the Steam Deck docked to a Hagibis dock and recorded via HDMI capture with the Ezcap333.

Does not work reliably — a Reddit user reports that after hooking up a cheap capture card to record their Steam Deck, the video in OBS was completely scrambled and white.

Mixed evidence: one Reddit user reports it works well and uses it for their Steam Deck, while another reports being unable to get it working with their Steam Deck.

Does not work when paired with a MacBook Pro M1 Max as the recording host — a Reddit user reports OBS is unable to recognize the capture card at all when trying to stream Steam Deck gameplay through it.

Despite the "Max" naming, the encoding silicon is unchanged from the base UHD Pro — anyone recording fast-paced Steam Deck gameplay at a consistent 60fps must manually drop the capture resolution to 1080p in the menu, since 4K is hard-capped at 30fps.

A YouTube video confirms Steam Deck gameplay recorded with no FPS loss using the NZXT Signal 4K30 in OBS Studio.

A dedicated review confirms streaming Steam Deck gameplay successfully, noting that HDCP detection had to be turned off to recognize the console's DisplayPort-over-USB-C output.

SIIG's own product listing for the CE-H3CT01-S1 names Steam Deck explicitly among its supported source devices.

The product manual/spec listing for the ezcap350 states it can record the screen of devices including the Steam Deck.

A Spanish-language YouTube video about Steam Deck temperatures lists the AVerMedia Live Gamer Portable 2 as one of two capture cards the creator uses for their Steam Deck content.

Community reviewers highlight this as a particularly good travel companion for Steam Deck/Switch — its built-in battery and screen mean no monitor or wall outlet is needed to record a session away from home.

A Spanish-language YouTube video about Steam Deck temperatures lists the Hauppauge HD PVR Rocket as one of two capture cards the creator uses for their Steam Deck content.

The product manual/spec listing for the V308 states it can record the screen of devices including the Steam Deck.

This capture dock is explicitly marketed and named as a "Capture Card Dock for Switch 2 & Steam Deck" — designed specifically for this use case rather than a generic device sold with an unrelated compatibility list.

Mixed evidence: comparison footage exists showing smooth playback with this card, but a Reddit user reports jittering/skipping frames and audio distortion when capturing their Steam Deck via HDMI and USB.

Works, but requires a manual EDID fix — the GC553 does not natively support the Steam Deck's 1280x800 resolution; a Reddit user edited and imported a custom EDID via AVerMedia's utility to get it recognized correctly.

The manufacturer explicitly recommends installing a Steam Deck-specific firmware version to maintain a stable connection with this exact device as the source.

A user reports insufficient power reaching a Steam Deck through a dock even with this 100W charger connected, pointing to dock-side power negotiation rather than the charger itself as the likely bottleneck.

Named as a compatible device on the official Baseus EU product listing.

Official Baseus product page explicitly lists compatible devices: "Macbook/ ROG Ally/ Laptops / Tablets /Steam Deck".

"I use a Satechi 165W 4-port charger. That charges my (non-gaming) laptop, Steam Deck, ROG Ally... Even works with my Legion Go S." Separate reports document a severe multiport load-balancing bug when a corporate HP EliteBook/ZBook G10 shares the charger with a second device.

A traveling user reports relying on this 65W charger for their Steam Deck. Negative caveat from a separate report: when a second cable is plugged into the same charger even without an active device on the other end, the Deck loses access to its optimal 15V/3A profile and falls back to a ~12W emergency profile; the charger has also been reported to thermal-throttle and disable the 20V rail after ~30 minutes of sustained 65W draw.

Official Anker product page explicitly warns: "Charging and playing a Steam Deck at the same time will significantly increase the time required to fully charge." Separate report documents a phantom-load bug: inserting a second USB-C cable into an unused port, even unpowered on the far end, drops the primary port from ~65W to a hard 45W limit.

Steam Deck operators using this exact model (A2668) document the OS occasionally showing a "slow charging" warning, a side effect of PowerIQ 4.0 continuously re-adjusting voltage in real time rather than a fixed 15V-profile fault.

A user measuring this exact charger reports it failed to deliver its rated power to a Steam Deck, categorically unable to sustain the console's charging draw.

Official Steam Community forum: "I have the Anker 715 Nano II 65W and it does PD, I use it often with my Steam Deck."

Official Baseus product page explicitly lists "Compatible Devices: Tablet, Laptop... Steam Deck". No independent third-party review found.

Sporadically negotiates only 60W on the port instead of full capacity (erratic behavior reported), but 60W is still well above the Deck's 45W requirement.

Documented as compatible in UGREEN's own product documentation. Same VBUS interruption bug documented separately applies: connecting/disconnecting a secondary device briefly cuts power on all active ports.

Official UGREEN product page explicitly lists: "compatible with MacBook Pro/Air/Neo, Dell XPS... iPad Air/Pro, Steam Deck, and more". Separate Reddit report documents the top two USB-C ports permanently ceasing to function after thermal fatigue under sustained high-power use.

"Has worked great for my steam deck and legion go for long drives. No issues at all... I have a Baseus 160W car charger."

Official UGREEN product page explicitly lists: "Compatible with MacBook, ChromeBook, Dell, HP... Steam Deck".

"The 12V charger is a Ugreen 69W (nice) one... just enough wattage on second USB-C port to charge a Steam Deck at the same time." Confirmed on the secondary port only, delivering marginal but sufficient power.

"I got myself Anker Prime 20,000mAh Power Bank (200W)... it can push higher power for my other devices."

Multiple Steam Deck OLED owners with this exact unit report a handshake failure where the console rejects the PD 3.1 profile, dropping to just 20W with charging-warning lights on — commonly worked around by inserting a USB-C hub or dock between the bank and the console.

A user links directly to this SKU (pcdiga.com/ppbl000001) while discussing power banks for the Steam Deck.

Video review describes it as sufficient to power "your laptop and handheld gaming PCs like the Steam Deck and ROG Ally". Some reports of DOA units requiring warranty replacement.

"Using a Cuktech 20 here, enough output to keep my steam deck charging while playing."

Confirmation found under the SKU "P63-E1" (same 100W/25000mAh spec as this SKU "B63" — likely the same physical product under a naming variant across sources).

Sufficient in isolation (140W) or using the two main ports simultaneously (70-100W each) — enough headroom above the ~45W Deck needs. Use one of the two primary USB-C ports, not the fixed-40W third port.

The manufacturer directly responded to a customer question about Steam Deck + MacBook compatibility: "It looks like the Cable Matters USB-C KVM Dock (Model: 201075...) should fit your needs perfectly" (2024-07-18). Power Delivery is asymmetric: 100W with a single host, but strictly capped at 65W per port with both hosts connected, which may limit turbo profiles on handhelds.
