This INIU power bank packs a substantial 20,000mAh (74Wh) capacity. Factoring in typical 80% efficiency, here’s how many full charges you can expect for popular gaming handhelds:

Nintendo Switch (16Wh): Roughly 3.7 charges
Steam Deck (40Wh): About 1.9 charges
Asus ROG Ally (40Wh): About 1.9 charges
Asus ROG Ally X (80Wh): Approximately 1 full charge
Lenovo Legion Go (50Wh): Around 1.5 charges

It includes three output ports: one 22.5W USB-C port and two USB-A ports with Quick Charge 4+ support. This is sufficient for fast-charging a Nintendo Switch at its peak 18W rate. It will also charge an iPhone 16 at close to its maximum speed (ChargerLAB tests show the Pro Max caps at 30W).

Its compact size means no worries at airport security. The 20,000mAh capacity is well under the TSA's 27,000mAh carry-on limit. Measuring just 5.3 x 1 x 2.7 inches, the INIU power bank is discreet and travel-friendly.
