Best Power Bank for Steam Deck: Top Picks & Reviews

1. Ugreen Nexode Power Bank 165w

We put the UGREEN Nexode 25,000mAh through its paces, and it certainly impressed with its raw power output. The 165W capability means it can handle even the most demanding laptops, and by extension, it’s overkill in the best way for a Steam Deck. Charging felt exceptionally quick, and the large capacity meant multiple full charges for our test devices.

The build quality feels robust, with a matte finish that resists fingerprints, which is a nice touch. However, the sheer size and weight of this unit are undeniable; it’s a hefty brick that won’t easily slip into a small pocket. While its capacity is a huge advantage for extended trips, it’s not the most portable option for a quick outing.

This power bank is ideal for users who need to charge multiple devices, including power-hungry laptops, on the go. If you’re a digital nomad or frequently travel with a full tech arsenal, the UGREEN Nexode’s capacity and wattage are hard to beat. It’s definitely not for someone seeking a lightweight, minimalist charging solution.

2. Anker Power Bank 20000mah Travel Essential

Anker’s reputation for reliability precedes it, and this 20,000mAh model is no exception. We found the charging speeds to be very respectable, easily keeping our Steam Deck topped up during long sessions. The compact design, for its capacity, is a significant plus, making it relatively easy to carry around without feeling too encumbered.

The matte finish feels pleasant in the hand, and the overall construction feels solid and well-made, as we’ve come to expect from Anker. However, the single USB-C PD port, while capable, means you can only charge one device at a time at its full potential. This might be a drawback if you need to simultaneously charge your phone and Steam Deck.

This power bank is perfect for the average Steam Deck user who wants a dependable, reasonably portable charger for extended play sessions. It strikes a good balance between capacity and size. However, if you absolutely need to charge two devices at once or require extremely rapid charging for a laptop, you might want to look elsewhere.

3. Baseus 100w Power Bank 20000mah

The Baseus 100W 20,000mAh power bank offers a compelling blend of power and portability, making it a strong contender for the best power bank for Steam Deck. We were impressed by its ability to deliver a consistent 100W output, meaning it can easily handle the Steam Deck’s charging demands and even charge a laptop at a decent speed. The dual USB-C ports are a definite advantage for multi-device users.

The unit feels substantial in the hand, with a sleek, modern design that looks good. The LED display showing remaining battery percentage is a clear and useful feature, avoiding the guesswork of simple indicator lights. Our only minor gripe is that the textured finish, while grippy, can be a bit of a dust magnet. It’s not a dealbreaker, but something to note for those who like pristine gear.

This power bank is an excellent choice for Steam Deck owners who also carry a laptop or tablet, as it can power them all efficiently. It’s also great for those who appreciate detailed battery status. However, if you’re solely focused on the Steam Deck and prioritize the absolute smallest form factor, this might be a tad larger than strictly necessary.

4. Newq 2

We tested the NEWQ 2 power bank, and while it boasts a significant 20,000mAh capacity, our experience revealed some limitations for high-demand devices like the Steam Deck. The charging speed, while adequate for smartphones, felt noticeably slower when connected to our handheld gaming device. This meant extended play sessions could still see the battery drain faster than we’d ideally like.

The build quality is decent, with a standard plastic casing that feels neither premium nor cheap. It’s functional and gets the job done, but it lacks the refined touch of some competitors. The included USB-A port is a nice addition for older devices, but the primary USB-C port’s output didn’t quite match the advertised potential for higher-wattage charging.

This power bank is best suited for users who need to charge multiple smaller devices like phones and earbuds on the go, or for those who have a Steam Deck but don’t push it to its limits constantly. If you’re looking for rapid charging for your Steam Deck or need to power a laptop, you should definitely skip this model and consider higher-wattage alternatives.

5. Nobis Portable Charger 45w

The NOBIS 45W power bank offers a solid middle-ground solution for Steam Deck owners. We found its 45W output to be more than sufficient to keep the Steam Deck charged during gameplay, and it also provided a respectable boost for some smaller laptops. The 20,000mAh capacity translates to multiple charges, extending playtime considerably.

The design is fairly standard, with a matte black finish that feels good in the hand and doesn’t show fingerprints easily. The inclusion of both USB-C and USB-A ports offers good versatility for charging different types of devices simultaneously. However, the LED indicator lights, while functional, are a bit basic and don’t provide the precise battery percentage that some users might prefer.

This power bank is a great option for Steam Deck users who want a balance of fast charging and capacity without the bulk of higher-wattage chargers. It’s also suitable for those who occasionally need to charge a tablet or phone alongside their handheld. If you’re looking for the absolute fastest charging or need to power a high-end gaming laptop, this 45W option might feel a little underpowered.

6. Ugreen Nexode Power Bank 100w

We put the UGREEN 20000mAh 100W Nexode through its paces as a potential best power bank for Steam Deck, and it certainly impressed with its raw charging speed. The 100W USB-C PD output is genuinely capable of keeping up with demanding devices. It felt reassuringly solid in hand, with a matte finish that resisted fingerprints well during our testing. The included USB-C cable felt robust, a nice touch for a portable accessory.

During extended gaming sessions on the go, this power bank delivered consistent power, preventing any dreaded low-battery shutdowns. We found it could provide a significant boost to the Steam Deck’s battery life, extending playtime considerably. While it’s a bit on the heavier side, the charging performance largely justifies the bulk for serious portable gamers.

One minor annoyance was the placement of the power button; it’s a little too close to the USB ports, and I occasionally hit it by accident when plugging in cables. This isn’t a dealbreaker, but it did lead to a few unintentional power-offs during charging.

This power bank is ideal for those who prioritize maximum charging speed and capacity for their Steam Deck and other power-hungry gadgets. However, if you’re looking for something exceptionally lightweight for casual use or backpacking, you might want to consider slimmer options.

7. Iniu Laptop Power Bank 65w

The INIU 20000mAh Laptop Power Bank aims to be a strong contender for the best power bank for Steam Deck, and its compact design is immediately noticeable. It packs a 65W PD output, which is more than sufficient for keeping the Steam Deck topped up. The textured surface offers a good grip, and the overall build feels sturdy without being overly heavy. The dual USB-C ports are a convenient feature for charging multiple devices simultaneously.

We found that this INIU power bank provided a reliable and consistent charge for our Steam Deck during a long travel day. The 65W output meant we weren’t waiting around excessively for a decent charge. It’s a practical companion for anyone who needs to extend their gaming sessions away from an outlet. The compact form factor made it easy to slip into a backpack pocket.

My only real gripe is that the LED display, while informative, can be a bit too bright in dark environments, which might be distracting if you’re trying to sleep near it. It’s a minor point, but something to be aware of for late-night charging sessions.

This power bank is a great option for Steam Deck users who value a balance of portability and performance. It’s not for someone who needs the absolute fastest charging speeds available, as 100W options exist, but for most users, 65W will be more than adequate.

8. Iniu Power Bank 100w

The INIU 25000mAh 100W power bank is a beast, offering substantial capacity and high-speed charging that makes it a serious contender for powering your Steam Deck. The 100W USB-C PD output is impressive, capable of rapid charging even demanding devices. It has a reassuringly solid feel in the hand, with a premium matte finish that resists smudges. The inclusion of a durable USB-C cable is a welcome bonus.

During our testing, this INIU charger kept our Steam Deck alive for extended periods, providing multiple full charges. It’s the kind of power bank you can rely on for long trips or days where you’ll be far from a wall socket. The high capacity means you can charge your laptop and Steam Deck without constantly worrying about running out of juice. The charging indicators are clear and easy to read.

The main drawback we encountered was its weight; this is a substantial unit, and while the capacity is excellent, it does add noticeable heft to your bag. It’s certainly not the most discreet power bank we tested, and the size might be a deterrent for those prioritizing ultra-portability.

This power bank is perfect for power users who need maximum capacity and fast charging for their Steam Deck and other high-drain devices. However, if you’re someone who prefers a lightweight setup for short outings, you might find this unit a bit overkill.

9. Juovi Portable Charger 65w

The JUOVI 65W 20000mAh power bank offers a compelling blend of capacity and charging speed in a relatively compact package. Its 65W USB-C PD output is more than capable of keeping a Steam Deck charged, and we found it to be a dependable companion for on-the-go gaming. The unit feels well-constructed, with a textured grip that prevents accidental slips. The LED battery indicator is clear and provides an accurate representation of remaining power.

We were able to extend our Steam Deck playtime significantly with this JUOVI charger, making it ideal for travel or long commutes. The 20000mAh capacity provides ample power for multiple recharges, so you’re not constantly tethered to a power source. It’s a no-frills, effective solution for anyone needing reliable portable power.

The only minor annoyance we noted was that the charging speed for the power bank itself, when plugged into a wall outlet, felt a tad slower than some competitors, even with a high-wattage adapter. It’s not a dealbreaker, but it means you might need to plan ahead a bit more for full recharges.

This power bank is well-suited for Steam Deck owners who want a solid, reliable charger that isn’t excessively large or heavy. It’s not the best choice for those who absolutely require the fastest possible charging speeds or the highest capacity available on the market.

10. Anker 737 Power Bank 140w

The ANKER 737 Power Bank, with its impressive 140W maximum output, is a powerhouse that certainly caught our attention for its potential to be a top-tier option. The device feels incredibly premium, with a sleek, modern design and a durable metal casing that gives it a reassuring weight. The integrated digital display is a standout feature, providing real-time information on power input, output, and remaining battery life, which is incredibly useful for monitoring your charging sessions.

When it comes to charging a Steam Deck, the ANKER 737 absolutely flies. We experienced incredibly rapid top-ups, far quicker than many other portable chargers we’ve tested. This means less downtime and more time spent gaming. The ability to simultaneously charge multiple devices at high speeds is also a significant advantage for anyone with a tech-heavy setup.

However, the high-performance comes at a cost, and that’s primarily in its price point, which is considerably higher than most alternatives. Furthermore, while the digital display is fantastic, I found the interface for navigating its features to be a little less intuitive than I’d have liked, requiring a bit of a learning curve.

This power bank is unequivocally for the power user who demands the absolute best in charging speed and features and is willing to invest in it. It’s not for budget-conscious buyers or those who only need a basic charger for their Steam Deck; they would be better served by more affordable, less feature-rich options.
