The 10 Best Power Bank for the Steam Deck Reviewed
1. Anker Power Bank, 20,000mah
We put the Anker 20,000mAh power bank through its paces as a potential companion for the Steam Deck. Its substantial capacity is a clear draw, promising multiple charges on the go. The build quality feels robust, as we’ve come to expect from Anker, with a matte finish that resists fingerprints well.
During our testing, we found its portability to be decent, though it’s not the slimmest option available. The included USB-C cable felt a little short for comfortable use while charging and playing simultaneously. However, the dual USB-A ports offer flexibility for charging other devices alongside your Deck.
This power bank is an excellent choice for extended travel or long days away from an outlet, especially if you prioritize capacity and brand reliability. It’s a solid, no-nonsense option for anyone needing dependable power for their handheld gaming needs.
Pros
- High capacity for multiple charges
- Durable build quality
- Reliable brand reputation
Cons
- USB-C cable is a bit short
- Not the most compact design
2. Baseus 100w Power Bank, 20000mah
The Baseus 100W power bank immediately impresses with its high wattage output, capable of fast-charging even demanding devices. Its 20,000mAh capacity is ample for several Steam Deck charges, and the inclusion of a built-in display showing power output is a welcome touch for monitoring. The textured finish provides a good grip.
We noticed the unit runs a bit warmer than expected when pushing its full 100W output, which might be a minor concern for some users. While it’s designed for laptops, its power delivery is certainly overkill for just the Steam Deck, meaning you might be paying for features you won’t fully utilize.
This power bank is best suited for those who also need to charge laptops or other high-power devices and want a single solution. If your primary need is just for the Steam Deck and you don’t own other power-hungry gadgets, you might find more cost-effective options.
Pros
- 100W output for rapid charging
- Informative power display
- Good grip texture
Cons
- Can get warm under heavy load
- Potentially overkill for Steam Deck only
3. Newq 20000mah Power Bank
We tested the NEWQ 2, and its compact size is its immediate standout feature for a power bank of this capacity. It boasts a respectable 20,000mAh, which is a sweet spot for portability and power for the Steam Deck. The matte plastic shell feels decent, though it doesn’t exude premium quality.
The charging speeds were satisfactory for our Steam Deck, providing a noticeable boost without excessive wait times. However, the single USB-C port for input/output means you can’t charge the power bank and your device simultaneously, which is a slight inconvenience during extended use. The LED indicators are basic but functional.
This is a solid contender for the best power bank for the Steam Deck if you prioritize a smaller footprint. It’s ideal for those who travel light and don’t need to charge multiple devices at once. Gamers who often find themselves in situations where space is limited will appreciate its design.
Pros
- Compact and portable design
- Good capacity for its size
- Adequate charging speeds
Cons
- Single USB-C port limits simultaneous charging
- Build quality feels less premium
4. Anker Laptop Power Bank, 25,000mah
Anker’s 25,000mAh offering is a serious contender for power users, boasting a substantial capacity and triple 100W ports. This means it can handle charging the Steam Deck, a laptop, and another device concurrently at impressive speeds. The unit has a solid, substantial feel in hand, indicating robust internal components.
We found the sheer size and weight of this power bank to be its primary drawback for casual transport. While the capacity is fantastic, carrying it around in a small bag can be cumbersome. The cooling vents on the side are a good design choice, suggesting efficient heat management during high-power output.
This power bank is best suited for digital nomads or professionals who need to keep multiple high-power devices alive throughout the day. If you’re only looking for a Steam Deck charger and value extreme portability, this unit is likely overkill and too bulky for your needs.
Pros
- Massive capacity
- Triple 100W ports for simultaneous charging
- Robust build
Cons
- Large and heavy for casual use
- Can be cumbersome to carry
5. Iniu 20000mah Laptop Power Bank, 65w Pd
The INIU 20000mAh power bank strikes a good balance between capacity, power delivery, and a relatively compact form factor. Its 65W PD output is more than enough to fast-charge the Steam Deck, and the dual USB-C ports allow for charging two devices at once, or charging the power bank while using one port. The textured, slightly grippy surface feels nice to the touch.
We noticed that while it advertises fast charging, sustained high-output charging did cause the unit to warm up noticeably. The LED display, while helpful, is a bit basic in its information presentation. It’s not the absolute smallest 20,000mAh unit we’ve seen, but it’s certainly manageable.
This power bank is an excellent all-rounder for Steam Deck owners who also carry other USB-C devices. It’s a great choice for students or travelers who need reliable, fast charging without sacrificing too much pocket or bag space. Skip this if you absolutely need the smallest possible power bank or require ultra-high wattage for a laptop.
Pros
- Good balance of size and capacity
- Dual USB-C ports for flexibility
- 65W PD for fast charging
Cons
- Can get warm under sustained high load
- Basic LED display
6. Juovi Portable Charger 65w Power Bank 20000mah
We put the JUOVI 65W to the test, and it offers a solid punch for its compact size. The 20000mAh capacity is more than enough to keep a Steam Deck topped up for extended gaming sessions, and the 65W output means it charges the deck relatively quickly. It feels substantial in the hand without being overly bulky, a good balance for travel.
The build quality is decent; the matte finish resists fingerprints well, though the plastic casing does feel a little generic. We appreciated the clear LED indicator showing remaining battery life. However, the dual USB-C ports, while convenient, can feel a bit cramped when using two larger cables simultaneously.
This power bank is ideal for the commuter or casual gamer who wants reliable power on the go. It’s not the absolute fastest charger out there, but it’s efficient and dependable. If you’re looking for an all-around performer that won’t break the bank, this is a strong contender.
Pros
- Good capacity for Steam Deck
- Compact for its power
- Relatively fast charging
Cons
- Plastic build feels a bit basic
- USB-C ports can be tight
7. Iniu 20000mah Laptop Power Bank, 65w Pd
When searching for the best power bank for the Steam Deck, the INIU 65W Ultra Compact quickly caught our attention. Its 20000mAh capacity provides ample juice for lengthy gaming marathons, and the 65W Power Delivery is more than capable of keeping the Steam Deck charged even under load. We found the “ultra compact” claim to be largely true; it’s noticeably smaller than many rivals with similar specs.
The device boasts a premium feel with its textured finish, which also aids in grip. The dual USB-C ports are a definite plus, allowing for simultaneous charging of multiple devices. However, we did notice that the included USB-C cable, while functional, felt a bit flimsy and might not hold up to rigorous daily use.
This INIU power bank is perfect for the gamer who prioritizes portability and wants a device that can also handle their laptop or tablet. If you travel frequently and need a versatile charger that doesn’t add much bulk to your bag, this is a solid choice. Those who demand the absolute fastest charging speeds might want to look elsewhere, but for most users, this hits a sweet spot.
Pros
- Very compact for its capacity
- Premium textured finish
- Dual USB-C ports
Cons
- Included cable feels low quality
8. Ugreen Power Bank 25,000mah 145w
The UGREEN Nexode 3 is an absolute powerhouse, boasting a massive 25,000mAh capacity and an impressive 145W output. This is overkill for just a Steam Deck, but if you need to simultaneously charge your laptop, phone, and the Deck, this unit shines. We found it charged our devices remarkably fast, often matching wall charger speeds.
The build quality is robust, with a solid, professional-looking matte black finish that feels durable. The inclusion of multiple USB-A and USB-C ports provides excellent versatility. Our main gripe is its weight and size; it’s undeniably bulky and heavy, making it less ideal for pocketability. The fan, while quiet, is noticeable in very silent environments.
This charger is for the power user who needs to keep multiple high-drain devices running at all times, especially during travel or work. If you’re a digital nomad or a student who relies heavily on their devices, this is an excellent investment. Casual users or those who only need to top up their Steam Deck might find this unit unnecessarily large and powerful.
Pros
- Massive capacity and high wattage
- Charges devices extremely quickly
- Versatile port selection
Cons
- Quite bulky and heavy
- Fan noise is audible
9. Iniu Power Bank, 25000mah 100w
The INIU 25000mAh 100W offers a compelling blend of capacity and charging speed. We were impressed by its ability to deliver 100W, which is more than enough to rapidly charge a Steam Deck and even power a laptop. The 25000mAh capacity provides multiple full charges for the handheld. It feels well-constructed with a grippy texture.
The design is sleek and modern, and the LED display that shows the exact percentage of battery remaining is a welcome feature over simple indicator lights. However, we found the power button to be a bit too sensitive; it’s easy to accidentally press it when pulling the device out of a bag, leading to unintended activation.
This power bank is a fantastic option for anyone who needs substantial power for extended periods, whether for gaming, work, or travel. It’s particularly suited for those who often find themselves away from power outlets for days at a time. If you’re someone who frequently misplaces or forgets to charge their devices, the large capacity here is a lifesaver. Just be mindful of that sensitive button.
Pros
- Excellent capacity and 100W output
- Clear LED percentage display
- Good build quality
Cons
- Power button is overly sensitive
10. Juovi Power Bank 65w 20000mah
We tested the JUOVI 65W 20000mAh, and it provides a reliable and fairly compact charging solution. The 65W Power Delivery is sufficient to keep the Steam Deck charged during gameplay and offers a decent charging speed. Its 20000mAh capacity is a sweet spot, offering several recharges without becoming excessively large.
The unit has a straightforward design with a matte finish that resists smudges. The inclusion of both USB-C and USB-A ports adds a touch of versatility. However, we found the plastic casing, while lightweight, to feel a bit less premium than some competitors, and the included USB-C cable was rather short for our liking.
This JUOVI power bank is a solid choice for the average user looking for dependable portable power for their gaming devices and smartphones. It strikes a good balance between size, capacity, and charging capability. Those who require the highest wattage for multiple high-drain devices or demand a more premium feel might want to explore other options, but for everyday use, it performs admirably.
Pros
- Good balance of size and capacity
- 65W PD for efficient charging
- Versatile port options
Cons
- Plastic build feels a bit cheap
- Short included USB-C cable

Frequently Asked Questions
Can I Use Any USB-C Power Bank for My Steam Deck?
No, not all USB-C power banks are suitable. The Steam Deck requires a significant amount of power to charge effectively, especially when in use. It can draw up to 45W.
You need a power bank that supports USB Power Delivery (PD). This protocol allows for higher wattages. Without sufficient PD output, your Steam Deck will charge very slowly, or not at all during gameplay.
What Is the Minimum Mah Capacity I Should Look for?
For a useful charge, aim for at least 10,000mAh. This will provide roughly one full charge for your Steam Deck. A 20,000mAh power bank is ideal for multiple charges or longer trips.
Remember that the Steam Deck’s battery is 40Wh. A 10,000mAh power bank at a standard 3.7V offers about 37Wh. Real-world efficiency losses mean you’ll get less than a full charge from a 10,000mAh unit. Higher capacity ensures more playtime.
Will a Lower Wattage Power Bank Damage My Steam Deck?
A lower wattage power bank will not typically damage your Steam Deck. The device will simply charge much slower. It might not even charge while you are actively playing demanding games.
The Steam Deck is designed to only draw the power it can safely receive. However, using a power bank that doesn’t meet its charging needs can be frustrating. It’s best to match the power output for optimal performance.
How Many Times Can a 20,000mah Power Bank Charge My Steam Deck?
A 20,000mAh power bank can charge your Steam Deck approximately 1.5 to 2 times. This depends on the actual usable capacity after accounting for charging inefficiencies and voltage conversion losses.
The Steam Deck’s battery is 40Wh. A 20,000mAh power bank, assuming a standard 3.7V, has about 74Wh of total energy. Real-world charging efficiency is typically around 70-80%, meaning you get about 50-60Wh of usable power.
Are There Any Power Banks Specifically Designed for the Steam Deck?
While there aren’t many power banks exclusively marketed for the Steam Deck, many manufacturers offer excellent options that meet its requirements. Look for reputable brands that clearly state USB PD support and high wattage output.
The key is compatibility. Any high-quality power bank with at least 45W USB PD output and a decent capacity (10,000mAh or more) will work very well. Brands like Anker, RAVPower, and Zendure are good places to start your search.
Final Verdict
For the best power bank for your Steam Deck, we recommend the Anker 737 Power Bank (PowerCore 24K). It offers a substantial 24,000mAh capacity, ensuring multiple full charges for extended gaming sessions. Crucially, it delivers a powerful 140W USB-C PD output, far exceeding the Steam Deck’s 45W requirement, guaranteeing rapid charging even during intense gameplay. Its robust build quality and multiple ports also make it a versatile choice for all your portable charging needs.
