This INIU power bank packs a 10,000mAh (37Whr) capacity, capable of charging a Nintendo Switch OLED from zero to full approximately 1.9 times, an iPhone 16 around 2.2 times, and an iPhone 16 Pro Max about 1.7 times. It includes three output ports: one 20W PD USB Type-C, one 12W USB Type-C, and one USB Type-A port with QuickCharge 4 support. The USB Type-C PD port charges the Nintendo Switch at its maximum 18W speed and also powers up the iPhone 16 at near-peak rates (ChargerLAB tests indicate the Pro Max can reach up to 30W).
Thanks to its compact size, this power bank easily complies with TSA regulations. Its 10,000mAh capacity is well under the 27,000mAh limit for carry-on luggage. The slim, discreet design means it's unlikely to attract attention. Even if screened, its wattage falls within approved limits.
