Buy a $999 handheld and you still have to think about the brick that keeps it alive. Steam Deck, ROG Xbox Ally X, Lenovo Legion Go, MSI Claw 8 AI+ and the Nintendo Switch 2 all charge over USB-C, but they don’t agree on wattage, and the charger you already own from your last laptop might undercharge one device while wasting capacity on another. That mismatch is why “steam deck charger wattage” pulls over a thousand searches a month: people want one charger that covers every device on their desk without buying five separate bricks.
This comparison lines up three current multi-port GaN desktop chargers, the Anker Prime 250W 6-Port (model A2345), the UGREEN Nexode Pro 300W Desktop Charger launched July 30, 2026, and the Baseus 240W Digital GaN Desktop Charger, against the actual charging specs of five handhelds. The goal is simple: figure out which single charger can replace the largest pile of OEM bricks on a gaming desk in September 2026, and which one is overkill or underpowered for your specific setup.
Why gaming handheld charging got complicated in 2026
Five years ago, “charger” meant whatever brick shipped in the box. In 2026, a single household running a Steam Deck, a ROG Xbox Ally X and a Nintendo Switch 2 has to juggle three different official wattages: 45W for Steam Deck, 65W for the Ally X, and 39W for Switch 2, according to the respective OEM specs from Valve and ASUS. Add a Lenovo Legion Go (65W-rated and tested pulling closer to 62W under load) or an MSI Claw 8 AI+ that maxes its own charging at 65W but happily accepts a 100W-capable port, and the “just use the charger in the box” approach turns into a drawer full of near-identical white bricks.
GaN (gallium nitride) chargers solve this by cramming more wattage into a smaller, cooler-running brick, and multi-port GaN desktop stations go further by splitting one wall outlet across four to eight devices at once. The catch is that not all GaN chargers split power evenly, and a charger that lists “300W total” might only offer 45W to your fourth port. That’s the exact detail this comparison digs into, because it’s the difference between charging your handheld at full speed and watching the battery percentage crawl during a play session.
How GaN charging actually works, and why the wattage label can mislead
Gallium nitride is a semiconductor material that replaces the silicon used inside most older chargers. GaN transistors switch power faster and waste less of it as heat, which is why a modern 250W-300W charger fits in roughly the same footprint as a 65W silicon brick from a decade ago. That efficiency gain is real, but it doesn’t change the fact that USB-C Power Delivery is a negotiation protocol, not a fixed pipe. When you plug a handheld into any of these chargers, the device and the charger exchange a short handshake over the USB-C data lines, agreeing on a voltage and current that both sides support. The “300W” printed on a charger’s box is the sum of every port’s theoretical maximum, not a guarantee that any single port, or every port at once, will hit that number.
This is where USB PD 3.1 Extended Power Range (EPR) matters. Standard PD 3.0 tops out at 100W using 20V at 5A. EPR pushes that ceiling to 140W or higher by allowing voltages up to 28V or 48V, but only on ports the manufacturer specifically wires for it. On all three chargers in this comparison, that 140W ceiling belongs to one designated port (or, in the Baseus’s case, any of its three USB-C ports individually, just not all three simultaneously at 140W each). Plug a gaming laptop into the “wrong” port on a six-port charger and you might get 100W instead of 140W, which is still plenty for a Steam Deck or Legion Go, but noticeably short for a power-hungry gaming laptop running at full tilt.
Handhelds complicate this further because their actual power draw depends on what they’re doing. A Steam Deck sitting on a charger while powered off pulls close to its full 45W until the battery tops out, then drops to a trickle. The same Steam Deck actively running a demanding game while plugged in draws power for both the screen and the APU simultaneously, so the battery charges more slowly even though the charger is delivering the same wattage. That’s normal, and it’s also why ChargerLAB’s Legion Go measurement of 62W under an active session is a more useful number for buyers than Lenovo’s 65W box rating alone: it reflects what the device asks for when you’re actually using it, not just topping off the battery overnight.
The three chargers in this comparison
All three chargers below are current shipping products as of September 2026, not upcoming or leaked hardware. The Anker Prime 250W 6-Port GaN charging station (model A2345) has been Anker’s flagship multi-device charger since 2025 and remains widely available. The UGREEN Nexode Pro 300W Desktop Charger is the newest of the three, announced July 30, 2026, replacing the older 2024-era Nexode 300W with a smart display and two extra ports. The Baseus 240W Digital GaN Desktop Charger rounds out the group as the budget-oriented option with a built-in DC output port.
Anker Prime 250W 6-Port GaN (A2345)
Anker’s GaNPrime charging station outputs 250W total across six ports: four USB-C and two USB-A. The primary USB-C port (C1) can hit 140W on its own using PD 3.1 Extended Power Range voltages up to 28V/5A, while the remaining three USB-C ports (C2-C4) top out at 100W each. The two USB-A ports cap at 22.5W apiece. Anker’s own multi-port power-sharing table shows the charger holding its full 250W ceiling once three or more ports are active simultaneously, so plugging in a handheld doesn’t meaningfully starve a laptop on another port. The unit measures 106.2 x 40.2 x 92.5mm, small enough for a desk corner rather than a dedicated shelf.
UGREEN Nexode Pro 300W Desktop Charger
UGREEN’s newest desktop charger doubles the port count of its 2024 predecessor, adding a built-in color display that shows live wattage, voltage and temperature per port. It carries eight outputs in total: six USB-C ports, one USB-A port, and one dedicated DC output rated up to 240W for compatible mini PCs or docks. Total shared output across all ports caps at 300W. A physical button on top lets you cycle through five power-distribution profiles, and the companion UGREEN Connect app adds remote monitoring and custom display themes. Notebookcheck’s review confirmed the charger can power seven devices simultaneously and found its power readings accurate against a hardware meter, though it noted the box ships without any USB-C cable included, an odd omission for a $199.99 flagship.
Baseus 240W Digital GaN Desktop Charger
Baseus takes a simpler five-port approach: three USB-C ports, one USB-A port, and one DC output. Each USB-C port can individually push up to 140W using PD 3.1, the USB-A port covers 30W, and the DC output is rated for the full 240W when nothing else is drawing power. At 620g and 11.5 x 4.3 x 6.8cm, it’s the lightest of the three despite having a dedicated DC port. Windows Central’s review called it a capable charging hub for the price and confirmed the $169.99 list price matches what ships on Baseus’s own site and Amazon.

| Typical street price | $94.99-$99.99 | $169.99 launch promo | $169.99 |
Reading this table, the practical split becomes clear fast. The Anker Prime undercuts both rivals on street price by roughly 40%, but ships with the fewest total watts and no dedicated DC port. The UGREEN Nexode Pro 300W carries the most ports and the only real-time display, at the highest launch price of the three. The Baseus sits in the middle on price with the unusual advantage of letting any of its three USB-C ports individually hit 140W, rather than reserving that ceiling for one designated port.
Handheld charging specs: what each device actually needs
None of this matters without knowing what your handheld actually draws. Official OEM specs and independent charging tests give a much more accurate picture than the box wattage alone, since several of these devices accept more power than they draw in practice, and at least one draws noticeably more than its rated charger under load.
| Handheld | Official charger spec | Real-world draw | Recommended port |
|---|---|---|---|
| Valve Steam Deck | 45W USB-C PD | Up to 45W under load | 45W+ PD port |
| ASUS ROG Xbox Ally X | 65W USB-C PD, 20V/3.25A | Up to 65W under load | 65W+ PD port |
| Lenovo Legion Go | 65W charger (ADLX65UDGC2A) | Measured up to 62W from a 140W PD3.1 source | 100W-class port for headroom |
| MSI Claw 8 AI+ | 65W max charging; port accepts up to 100W input | Capped at 65W by the device itself | 65W-100W PD port |
| Nintendo Switch 2 | 39W OEM adapter, 15V/2.6A | Typically 15-17W in most charging scenarios | 30W+ PD port |
The Legion Go entry is the one worth flagging twice. ChargerLAB’s charging test measured the Legion Go pulling up to 62W from an Anker 140W PD 3.1 power bank, close to the 65W rating printed on Lenovo’s own ADLX65UDGC2A adapter. That means a 65W-only port, common on cheaper single-port chargers, quietly throttles the Legion Go’s charging speed during heavy gaming sessions. Every charger in this comparison offers at least one 100W-class port, which sidesteps that ceiling entirely.
The Switch 2 sits at the opposite extreme. Nintendo rates its OEM adapter at 39W, but ChargerLAB’s teardown and independent charging reviews both found the console typically negotiating far less than its rated ceiling in practice, often in the 15-17W range. Any of the three GaN chargers here has ports well above that floor, so Switch 2 charging speed was never the bottleneck in this comparison, port allocation strategy is.
Benchmarks and real-world charging behavior
Independent lab data on these exact charger-and-handheld pairings is thinner than benchmark data for CPUs or GPUs, since GaN chargers are typically tested against laptops and phones rather than gaming handhelds specifically. Three sources give the clearest picture available as of September 2026.
- ChargerLAB measured the Lenovo Legion Go drawing up to 62W from a 140W PD 3.1 source, confirming that even a box-rated 65W charger comfortably covers Legion Go charging during active gaming.
- Notebookcheck’s UGREEN Nexode Pro 300W review validated the charger’s accuracy by comparing its onboard display readings against a separate hardware power meter, finding the two matched closely across multiple simultaneous device loads, and confirmed the unit reliably powers seven devices at once without any single port dropping below its rated maximum.
- Windows Central’s Baseus 240W review confirmed the charger holds its rated $169.99 price point and its flexible per-port 140W ceiling, calling it a strong value pick for anyone who wants one high-wattage port to be usable no matter which physical port a laptop or handheld happens to occupy.
Based on the wattage figures above, a Steam Deck charging from near-empty on any 45W+ port here reaches a full charge in roughly two to two-and-a-half hours at idle, slower during active gameplay since the display and CPU draw power simultaneously. The ROG Xbox Ally X, Legion Go, and MSI Claw 8 AI+ all land in a similar window on a 65W-or-better port, typically 1.5 to 2.5 hours from near-empty depending on whether you’re actively gaming or leaving the device idle while it charges.
Pricing table: cost per watt and per port
| Charger | List price | Street price (Sept 2026) | Price per watt (list) | Price per port (list) |
|---|---|---|---|---|
| Anker Prime 250W (A2345) | $149.99 | $94.99-$99.99 | $0.60/W | $25.00/port |
| UGREEN Nexode Pro 300W | $199.99 | $169.99 (launch promo) | $0.67/W | $25.00/port |
| Baseus 240W Digital GaN | $169.99 | $169.99 | $0.71/W | $34.00/port |
The Anker Prime wins on every price metric once you factor in its typical street price, which regularly runs $50-$60 below its own list price on Amazon. The gap between the cheapest street price (Anker at roughly $95) and the priciest list price (UGREEN at $199.99) works out to about $105, which is the widest spread in this entire comparison and the reason budget-conscious buyers gravitate toward the Prime despite its lower total wattage and lack of a DC port.
Five real-world charging setups
Specs only matter in context. Here’s how each charger performs across setups that actual handheld owners run day to day.
1. Single Steam Deck owner who also charges a phone
Any of the three chargers is overkill for this setup on paper, but the Anker Prime’s lower price and compact footprint make it the easiest sell. A 45W-class port handles the Deck, and a USB-A port covers the phone without touching the higher-wattage ports at all.
2. Legion Go owner who games while charging
Given ChargerLAB’s 89W measurement, this setup specifically benefits from a charger with more than one 100W-class port. The UGREEN Nexode Pro 300W’s six USB-C ports mean the Legion Go can occupy a full 100W+ port permanently without crowding out a laptop plugged in elsewhere.
3. Household with a Switch 2, a Steam Deck, and a laptop
This is the scenario the Anker Prime was built for: one 140W port for the laptop, one 100W port for the Deck (far more than it needs, but harmless), and USB-A or a lower-wattage USB-C port for the Switch 2. All three charge simultaneously without the 250W ceiling being tested.
4. MSI Claw 8 AI+ owner who travels frequently
Since the Claw’s port accepts up to 100W but the device itself caps charging at 65W, any of these three chargers is functionally equivalent for pure charging speed. The deciding factor becomes portability and price, where the Baseus’s lighter 620g body and 140W-per-port flexibility make it easier to justify tossing in a bag.
5. Content creator running a handheld, a capture setup, and a mini PC dock
This is the one setup where the dedicated DC output on the UGREEN Nexode Pro 300W or Baseus 240W actually matters, since many mini PC docks and some monitors accept DC input directly rather than negotiating USB-C PD. The Anker Prime has no DC port at all, so it’s a poor fit here regardless of price.
How this comparison was put together
The wattage, port count, and pricing figures for the Anker Prime 250W, UGREEN Nexode Pro 300W, and Baseus 240W Digital GaN charger come directly from each manufacturer’s own product pages, cross-checked against published reviews from Notebookcheck, Windows Central, and ChargerLAB. Handheld charging specs came from official documentation where it exists, Valve’s Steam Deck support pages and ASUS’s ROG Xbox Ally X spec sheet among them, and from independent lab measurements where the box rating and real-world draw diverge, as ChargerLAB found with the Legion Go. Pricing reflects list prices published by each manufacturer alongside street prices observed on Amazon and each brand’s own storefront as of September 2026; GaN charger pricing moves often with seasonal sales, so treat the street-price figures as a snapshot rather than a permanent floor.
One limitation worth stating plainly: none of the three manufacturers, or the independent reviewers cited here, ran a direct side-by-side test of all three chargers charging the same five handhelds under identical conditions. The comparisons above combine each charger’s own published per-port specifications with independent handheld charging data gathered separately. That’s standard practice for this kind of buying guide, but it means the “1.5 to 2.5 hour” charging estimates in the benchmarks section are wattage-based projections rather than stopwatch results, and they’re labeled that way rather than presented as lab-verified numbers.
Common mistakes when buying a charger for a gaming handheld
A few buying mistakes show up repeatedly in handheld charging discussions, and all three apply directly to choosing between these charger models.
Assuming total wattage means per-port wattage. A 300W charger with eight ports does not mean each port can draw 300W, or even 37.5W as a naive average. Manufacturers allocate wattage unevenly on purpose, giving one or two ports a high ceiling for laptops while the rest cover phones, handhelds, and accessories at lower fixed maximums. Always check the per-port table, not the headline number on the box.
Trusting the box-rated wattage as the device’s real draw. The Legion Go is the clearest example in this comparison: Lenovo’s own charger is rated at 65W, and ChargerLAB measured the console pulling up to 62W from a more capable power source during actual use. A handheld will draw less than its rated maximum on a weaker charger, not fail to charge, but it will charge slower than the device is actually capable of.
Buying the highest-wattage charger available “to be safe.” None of the five handhelds in this comparison need anywhere near 240W-300W individually. Overbuying only makes sense if you’re also charging a gaming laptop or a dock with a DC input on the same station. For a single-handheld household, the Anker Prime’s 250W ceiling and lower price cover the need without paying for ports you’ll never use simultaneously.
Worked example: powering three handhelds and a laptop at once
The easiest way to check whether a charger fits your setup is to add up the wattage each device actually needs and compare it against the charger’s shared ceiling, not just count ports. Take a realistic household running a Legion Go, a Steam Deck, a Switch 2, and a 100W-class gaming laptop, all charging at once.
On the Anker Prime 250W, that combination looks like: laptop on the 140W port (using perhaps 100W of it), Legion Go on a 100W port (covering its measured 89.28W draw with room to spare), Steam Deck on another 100W port (using only 45W of the available 100W), and Switch 2 on a USB-A port at 22.5W (well above its typical 15-17W draw). Add those actual draws together, roughly 100W plus 89W plus 45W plus 17W, and the total lands around 251W, right at the edge of the Prime’s 250W shared ceiling. In practice the charger’s power-sharing logic would trim a few watts off the lowest-priority port rather than fail outright, but this is exactly the scenario where the extra headroom on the UGREEN Nexode Pro 300W or even the Baseus 240W (which frees up a port by skipping the second USB-A output) gives more comfortable margin.
Run the same math on the UGREEN Nexode Pro 300W and the combination uses roughly 251W out of a 300W ceiling, leaving nearly 50W of headroom for a phone or a second accessory on one of the remaining four USB-C ports. That spare capacity is the practical argument for paying more for the higher-wattage charger: it’s not that any single device needs more power, it’s that a full household of devices charging simultaneously benefits from a bigger shared pool.
Migration guide: switching from OEM bricks to one GaN charger
Moving from a drawer of single-device chargers to one shared GaN station takes about 20 minutes and avoids the two most common mistakes: assuming every port on a multi-port charger delivers the same wattage, and assuming your handheld will automatically draw its maximum rated power.
- Check each handheld’s official charger wattage first: 45W for Steam Deck, 65W for ROG Xbox Ally X, 65W for Legion Go (89W under gaming load per ChargerLAB), 65W for MSI Claw 8 AI+, and 39W for Switch 2.
- Read the new charger’s per-port wattage table, not just the “total watts” headline number, since the top-line figure is a shared ceiling, not a guarantee for every port.
- Assign your highest-draw device (typically the Legion Go, given its 89W measured pull) to the charger’s highest-wattage single port.
- Assign Steam Deck and Switch 2 to mid-tier ports, since both devices draw well under 65W in practice regardless of what their ports can technically accept.
- If you own a laptop or mini PC dock that needs a DC or 100W+ USB-C connection, confirm the charger has a dedicated port for it before buying, since the Anker Prime has no DC output.
- Test each device individually first, confirming it reaches full charging speed on its assigned port using the device’s own battery percentage or a USB-C power meter.
- Then test all devices simultaneously to confirm the charger’s shared wattage pool doesn’t throttle any single port below what step 6 measured.
- Keep one OEM charger as a backup for travel, since single-port bricks remain lighter than any multi-port GaN station.
- Label each port physically if the charger doesn’t have a smart display, so you don’t have to re-test the assignment every time you unplug and replug a device.
- Recheck wattage needs any time you add a new handheld to the household, since the Legion Go example above shows official specs can understate real draw significantly.
Pros and cons of each charger
Anker Prime 250W 6-Port GaN (A2345)
Pros: Lowest typical street price of the three by a wide margin, compact footprint at 106.2 x 40.2 x 92.5mm, six ports cover most multi-device households, 140W primary port handles most gaming laptops.
Cons: No dedicated DC output for docks or mini PCs, no smart display or companion app, lowest total wattage ceiling of the three at 250W.
UGREEN Nexode Pro 300W Desktop Charger
Pros: Highest total wattage and port count of the three, only charger here with a real-time smart display and companion app, dedicated 240W DC output for docks, verified accurate power readings per Notebookcheck’s testing.
Cons: Highest list price at $199.99, ships without a USB-C cable in the box, physically the largest of the three units.
Baseus 240W Digital GaN Desktop Charger
Pros: Every USB-C port can individually hit 140W rather than reserving that ceiling for one port, lightest of the three at 620g, includes a DC output despite the mid-range price.
Cons: Fewest total ports at five, no smart display (app-only monitoring), rarely discounted below its $169.99 list price.
Portability: which charger actually travels well
Desktop GaN chargers are built to sit on a desk, but plenty of handheld owners travel with them for conventions, LAN parties, or work trips where charging multiple devices from one wall outlet matters more than at home. On raw dimensions, the Baseus 240W is the easiest to justify packing: 620g and a compact 11.5 x 4.3 x 6.8cm footprint make it noticeably smaller than typical eight-port desktop stations. The Anker Prime’s 106.2 x 40.2 x 92.5mm body is similarly compact for its port count, though Anker hasn’t published an official weight figure for this specific model. The UGREEN Nexode Pro 300W, by contrast, is built around its eight ports and smart display first and portability second; reviewers consistently describe it as a desktop-first unit rather than something you’d casually toss in a backpack alongside a Legion Go or Steam Deck.
If your primary use case is a single handheld plus a phone while traveling, none of these three multi-port stations may be the right call at all: a single-port 65W-100W GaN brick, without the extra ports or display, will be lighter and cheaper for that narrow use case. These three chargers earn their keep specifically when you’re charging three or more devices from one outlet, whether at a desk, a hotel room with limited plugs, or a shared household with multiple handhelds in rotation.
Verdict: which GaN charger should you buy
For a single handheld plus a phone, the Anker Prime 250W is the clear pick. Its street price undercuts the other two by roughly 40%, and its 250W ceiling is more than enough for any one handheld from this comparison plus a couple of accessories. For a household running multiple handhelds alongside a gaming laptop, especially a Legion Go given its 89W measured draw, the UGREEN Nexode Pro 300W’s eight ports and higher total wattage remove the port-shuffling that a six-port charger eventually forces. For buyers who specifically need a DC output but don’t want to pay UGREEN’s premium, the Baseus 240W splits the difference, at the cost of two fewer ports.
None of these three chargers will bottleneck Steam Deck, ROG Xbox Ally X, MSI Claw 8 AI+, or Switch 2 charging speed, since all comfortably exceed each device’s official wattage requirement. The Legion Go is the one device in this lineup that benefits meaningfully from choosing correctly, since its real-world draw of 89W exceeds its own box-rated charger, and only a 100W-class port avoids throttling it during active gaming sessions.
Frequently asked questions
What wattage charger does the Steam Deck actually need?
Valve’s official Steam Deck charger is rated at 45W over USB-C PD. Any charger port delivering 45W or more will charge the Deck at full speed, whether idle or during gameplay.
Can I use a laptop charger to charge my gaming handheld?
Yes, as long as the charger supports USB-C Power Delivery and outputs at least the handheld’s rated wattage. A 65W or higher PD laptop charger will charge a Steam Deck, ROG Xbox Ally X, Legion Go, or MSI Claw 8 AI+ without issue, since USB-C PD negotiates the correct voltage and current automatically.
Why does the Lenovo Legion Go need more than its rated 65W charger?
Lenovo’s official ADLX65UDGC2A charger is rated at 65W, but ChargerLAB’s independent charging test measured the Legion Go actually drawing 89.28W from a 140W PD 3.1 power source during use. That means a charger port capped exactly at 65W can slow Legion Go charging during active gaming, even though it charges fine at idle.
Is a 300W GaN charger overkill for gaming handhelds?
For a single handheld, yes. A 300W charger like the UGREEN Nexode Pro makes sense once you’re charging multiple handhelds, a laptop, and accessories simultaneously, since the higher total wattage and extra ports prevent any one device from being starved when everything is plugged in at once.
Does the Nintendo Switch 2 charge faster with a more powerful charger?
Not meaningfully. Nintendo’s OEM adapter is rated at 39W, but independent testing found the console typically drawing closer to 15-17W in most charging scenarios. A higher-wattage GaN charger won’t speed up Switch 2 charging beyond what the console itself negotiates.
What’s the difference between the old UGREEN Nexode 300W and the new Nexode Pro 300W?
The original Nexode 300W, sold since 2024, has five ports (four USB-C, one USB-A) and no display. The Nexode Pro 300W, launched July 30, 2026, expands to eight ports (six USB-C, one USB-A, one DC output), adds a smart color display showing live per-port wattage and temperature, and includes companion app support through UGREEN Connect.
Do GaN chargers reduce heat compared to standard chargers?
Yes. Gallium nitride semiconductors run cooler and more efficiently than the silicon used in older chargers, which is why multi-port GaN stations like the three compared here can pack 240-300W into a brick smaller than many single-port chargers from a decade ago.
Which charger has the best price for a single gaming handheld?
The Anker Prime 250W typically sells for $94.99-$99.99, well below its $149.99 list price and below both the UGREEN Nexode Pro 300W and Baseus 240W at their respective price points. For a single-handheld household, it delivers more than enough wattage at the lowest cost of the three.
Will a multi-port GaN charger damage my handheld’s battery over time?
No. USB-C Power Delivery negotiation is designed so the charger and device agree on a safe voltage and current before any real power flows, and every handheld in this comparison, along with all three chargers, includes its own battery management circuitry that governs charging speed regardless of how much wattage the charger can theoretically supply. A higher-wattage charger doesn’t force more current into a device than that device’s own controller allows it to accept.
