The Iniu power bank weighs about 16 ounces, which is typical of most power banks with a similar battery capacity. It has thre ports: one USB Type-C port with 100W output, one USB Type-C port with 45W output, and one USB Type-A port with 18W output. Note that the maximum charging output is 100W. That means although all three ports add up to a total of 163W, only a maximum of 100W will be delivered across all three ports if they are used simultaneously.
The 25,000mAh capacity can fully recharge all of your gaming handhelds
This Iniu power bank boasts a generous 25,000mAh, or 92.5Whr 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 (16Whr) about 4.6 times
- Steam Deck (40Whr) about 1.9 times

- Asus ROG Ally X (80Whr) about 0.9 times
- Lenovo Legion Go (50Whr) about 1.5 times
- Lenovo Legion Go S (55Whr) about 1.3 times

The Asus ROG Ally X (and the upcoming Xbox Ally X) and Lenovo Legion Go S can actually achieve charging rates up to 100W. The Iniu is capable of maxing out all of these, which is rare for a power bank priced under $30.
