INIU Portable Charger, Slimmest 10000mAh 5V/3A Power Bank, USB C in&out High-Speed Charging Battery Pack, External Phone Powerbank Compatible with iPhone 15 14 13 12 11 Samsung S22 S21 Google iPad etc

The INIU BI-B41 is a 10000mAh portable power bank for recharging phones, tablets and earbuds away from a wall outlet. It measures 5.2 x 2.7 x 0.5 inches, weighs 7 ounces, holds a lithium polymer cell, and carries a USB-C port that works for both input and output alongside 5V/3A charging, so a single USB-C cable can refill the bank and top up a connected device. Compatibility covers iPhone 15, 14, 13, 12 and 11, Samsung Galaxy S22 and S21, Google phones and iPad, among others.

• In the box: the power bank, a 0.3M/1ft USB-A to USB-C cable, a travel pouch and a user manual
• Backed by a 30 day money-back guarantee, a 3 year warranty and lifetime technical support

Worth reaching for on travel days, long commutes or any stretch between outlets, particularly if pocket space is limited.

To get the most out of this power bank, keep it charged between 40 and 80 percent when storing it for extended periods, which helps preserve battery health over the long term. When comparing slim power banks like this one, pay attention to the total number of ports and whether the USB-C port handles both directions, since some budget options only charge the bank via USB-C while requiring a separate USB-A port for output. The included travel pouch is worth using daily, not just on trips, because it protects the surface from scratches in a bag and keeps the short cable together with the unit so neither gets lost separately.

This charger suits commuters, students and light travelers who prioritize carrying something flat over carrying maximum capacity. The half-inch thickness means it sits in a jacket pocket without creating a noticeable bulge, and the 10000mAh capacity is enough to fully recharge most smartphones twice before the bank itself needs refilling. Anyone who regularly carries a larger, heavier power bank and finds themselves leaving it at home on shorter trips would likely find this a more practical daily companion.
