This compact and efficient power bank packs a 10,000mAh (37Whr) battery, making it perfect for on-the-go charging. It can fully recharge a Nintendo Switch OLED approximately 1.9 times, an iPhone 16 about 2.2 times, and an iPhone 16 Pro Max around 1.7 times. Equipped with three versatile output ports, it offers:

• One 20W PD USB-C port (ideal for fast charging)
• One 12W USB-C port
• One USB-A port with QuickCharge 4 support

The 20W PD USB-C port delivers optimal charging speeds for devices like the Nintendo Switch (up to 18W) and the iPhone 16 series (close to maximum supported rates—ChargerLAB confirms iPhone 16 Pro Max caps at 30W).

With a capacity well under the TSA’s 27,000mAh carry-on limit, this power bank is travel-friendly and unlikely to raise any eyebrows at airport security. Its slim, pocket-friendly design ensures it slips easily into bags or even larger pockets without adding bulk. Even if a TSA agent decides to verify the watt-hour rating, you’re safely within regulations.
