This INIU power bank delivers a substantial 10,000mAh (37Whr) capacity, capable of fully charging a Nintendo Switch OLED approximately 1.9 times, an iPhone 16 around 2.2 times, and an iPhone 16 Pro Max about 1.7 times. It features three output ports: one 20W Power Delivery USB-C port, one 12W USB-C port, and a USB-A port supporting QuickCharge 4. The USB-C PD port charges the Nintendo Switch at its maximum 18W speed and comes close to delivering the fastest possible charge for an iPhone 16 (ChargerLAB tests show the Pro Max can charge at up to 30W).
The compact size of this power bank makes it ideal for travel, with its 10,000mAh capacity falling well below the TSA's 27,000mAh carry-on limit. Its slim, lightweight design is discreet enough to avoid drawing attention during security checks. Even if TSA officials conduct a power check, this power bank remains fully compliant with regulations.
