Two-Pack 12800mAh Power Banks

This product is a twin set of 12800mAh portable chargers designed for people who need backup power for phones and tablets while travelling. Each unit integrates two built-in cables so no separate cords are required. The slim profile and digital LED display make it easy to monitor remaining capacity on the go.

Suited for multi-device users.

The four simultaneous outputs suit families or individuals carrying a phone, tablet and accessories such as earbuds. Airline-approved capacity allows carry-on travel without restriction. Buyers who need higher-wattage output for laptops or larger devices should look at alternatives with greater power delivery capability.

Built-in cables and digital display

Two integrated cables — one Lightning and one USB-C — plus two USB-A ports eliminate the need to pack extra wires. The LED percentage readout replaces vague indicator lights so you know exactly when to recharge the power bank itself.
