It’s also the ideal battery capacity for more power hungry handhelds like the Asus ROG Ally and Legion Go.

INIU 20,000mAh 65W USB Power Bank
Iniu claims that this power bank is “ultra small”, and it certainly is smaller than most other 20,000mAh power banks in terms of footprint at only 4″ long and 3″ wide. However it’s also thicker at 1.1″ thick and weighs about the same at about 11 ounces. It has three ports: one USB Type-C port with 65W output, one USB Type-C port with 36W output, and one USB Type-A port with 18W output. Note that the maximum charging output is 65W. That means although all three ports add up to a total of 119W, only a maximum of 65W will be delivered across all three ports simultaneously.
The 20,000mAh capacity can fully recharge all of your gaming handhelds
This Iniu power bank boasts a generous 20,000mAh, or 74Whr battery capacity. If you factor in 80% power efficiency, here are the approximate number of times you can fully recharge each gaming handheld or iPhone model:
- Nintendo Switch 2 (18Whr) about 3.3 times
- Nintendo Switch (16Whr) about 3.7 times
- Steam Deck (40Whr) about 1.5 times
- Asus ROG Ally (40Whr) about 1.5 times
- Asus ROG Ally X (80Whr) about 0.7 times
- Lenovo Legion Go (50Whr) about 1.2 times
- Lenovo Legion Go S (55Whr) about 1 time
- Apple iPhone 16 (14Whr) about 4.2 times
- Apple iPhone 16 Plus (18Whr) about 3.3 times
The 65W output can fast charge nearly all phones and gaming handhelds
65W output is higher than what I see in most chargers at this price point and is capable of charging any phone or gaming handheld even while you’re playing games on it. It maxes out the charging rate on most gaming handhelds including the Nintendo Switch and Switch 2 (18W-20W), Steam Deck (35W), and Asus ROG Ally (65W). Some newer gaming handhelds like the Asus ROG Ally X and Lenovo Legion Go can accept up to 100W of charging, but it’s recommended to stick with 65W to maximum the battery’s lifespan. In fact, those two handhelds actually ship with official 65W chargers.
This power bank can be brought onto airplanes
You don’t need to worry about being stopped at airports. The 20,000mAh 74Whr capacity is well below TSA’s 27,000mAh/100Whr carry-on limit, so you are safely in the clear.
