This Iniu power bank features a substantial 20,000mAh (74Wh) battery capacity. Assuming 80% power efficiency, here’s approximately how many full charges it can provide for each gaming handheld or iPhone model:

Nintendo Switch (16Wh): about 3.7 times Steam Deck (40Wh): about 1.9 times Asus ROG Ally (40Wh): about 1.9 times Asus ROG Ally X (80Wh): about 1 time Lenovo Legion Go (50Wh): about 1.5 times Apple iPhone 16 (14Wh): about 4.2 times Apple iPhone 16 Plus (18Wh): about 3.3 times

This power bank includes three output ports: one 22.5W USB-C port and two USB-A ports with QuickCharge 4 support. The USB-C port charges the Nintendo Switch at its maximum 18W speed and nearly maxes out the iPhone 16’s charging rate (ChargerLAB tests show the Pro Max caps at 30W).

Travelers can rest easy, as the 20,000mAh capacity is well under the TSA's 27,000mAh carry-on limit. Iniu backs the product with a 3-year warranty.
