Taking your Steam Deck on the road is awesome – until that battery warning pops up mid-game. The handheld can chew through its built-in battery pretty quickly, especially with graphically demanding titles. That’s where a good power bank comes in handy.
But not every portable charger is suited for the Steam Deck. Since the Deck supports USB-C Power Delivery (PD) charging and can draw up to 45W, you’ll want a power bank that can deliver at least that much output. Going higher, like 65W, isn’t an issue – it just means you can also top up laptops or future-proof for other devices.
When picking a power bank for your Steam Deck, look for a few essentials: USB-C PD fast charging (45W minimum), a solid 20,000mAh or higher battery capacity for decent playtime extensions, and multiple ports if you want to charge your phone or other gadgets alongside it. With those requirements in mind, here are some of the best options available right now.

Best Power Banks for Steam Deck: Top Picks
Anker Power Bank 87W
Quick Highlights
- 87W maximum output through USB-C
- Built-in USB-C cable for convenience
- 20,000mAh capacity
- Travel-friendly design with TSA compliance
- Price – $69 – Buy Now
The Anker 87W power bank stands out with the highest power output in this lineup, delivering enough juice to charge your Steam Deck at full speed even during the most demanding games. The 87W output through USB-C PD means you’re getting faster charging than the Steam Deck’s own 45W charger, which translates to minimal downtime between gaming sessions. The built-in USB-C cable is a thoughtful touch that eliminates the need to carry extra cables, though you’ll still want to pack one as backup since built-in cables can’t be replaced if damaged.
With its 20,000mAh capacity, you’re looking at roughly 1.5 to 2 full Steam Deck charges depending on your usage patterns. The three-port design lets you charge multiple devices simultaneously, though keep in mind that the 87W is split between ports when charging multiple devices. At around 1.1 pounds, it’s reasonably portable considering the power it packs, and the TSA-approved capacity means no hassles at airport security.
Pros
- Highest wattage output for fastest possible charging
- Built-in cable reduces what you need to carry
- Reliable Anker build quality and safety features
Cons
- Premium pricing compared to competitors
- No display to show remaining battery percentage
- Built-in cable could be a point of failure

INIU’s 65W power bank hits the sweet spot between price and performance, delivering enough power to keep your Steam Deck charging during gameplay without breaking the bank. The 65W output through USB-C PD 3.0 ensures your Steam Deck maintains charge even during graphically intensive titles, while the 20,000mAh capacity provides enough juice for extended gaming sessions away from wall outlets. The compact design is surprisingly pocket-friendly for a 20,000mAh unit, making it easier to toss in a backpack compared to bulkier alternatives.
The three-port configuration includes two USB-C ports and one USB-A, giving you flexibility in charging multiple devices. While it lacks fancy features like built-in cables or digital displays, INIU focuses on the essentials with solid build quality and reliable performance. The power bank supports pass-through charging, meaning you can charge it while simultaneously charging your devices, though this isn’t recommended for regular use as it can impact long-term battery health.
Pros
- Excellent value for the specifications

Cons

- Price – $79 – Buy Now
The Baseus power bank is the capacity king of this lineup, packing 30,000mAh that can charge your Steam Deck roughly 2.5 to 3 times from empty. The digital display is genuinely useful, showing exact battery percentage remaining rather than vague LED indicators, so you’ll know precisely when it’s time to recharge. With seven ports total, this becomes a charging hub for all your devices – perfect for travel or as a desk companion when outlets are scarce.
The 65W output through USB-C PD 3.0 keeps your Steam Deck powered during play, while the additional ports support various fast charging protocols including QC 4.0 for compatible devices. Despite the massive capacity, Baseus has managed to keep the size reasonable, though at 1.4 pounds it’s definitely the heaviest option here. The black finish resists fingerprints well, and the sturdy construction feels like it can handle the rigors of daily use and travel.
Pros

- Compact travel-ready design
- Price – $46 – Buy Now
The UGREEN Nexode takes a slightly different approach with its 45W output, which matches the Steam Deck’s original charger specifications perfectly. While this means slightly slower charging than the 65W options, it’s still sufficient to maintain battery level during gameplay for most titles. The built-in cable is well-implemented with a clever storage groove that keeps it from flopping around, and the digital display provides clear battery level information at a glance.
At 20,000mAh, you’re getting the standard capacity that provides good balance between size and runtime. The three-port configuration covers most charging scenarios, and UGREEN’s reputation for quality electronics shines through in the build quality. The power bank supports multiple fast charging protocols, making it versatile enough for everything from laptops to earbuds, though the 45W maximum output means laptop charging will be slower than higher-wattage alternatives.

The three-port design keeps things simple with two USB-C ports and one USB-A, covering most modern devices without overcomplicating the layout. Build quality is respectable with a textured finish that provides good grip and resists scratches.
