Two 5000mAh power banks for daily carry

This pack contains two cylindrical power banks, each rated at 5000mAh capacity. They are built for commuters, travellers and anyone needing a lightweight backup for smartphones, a Meta VR headset, a PS5 controller or small single-board projects. The 5 V, 3 A USB-C port delivers up to 15 W to compatible devices.

USB-C in and out simplifies cables

Each unit uses a single USB-C port for both input and output, so the same cable recharges the bank and powers your gear. No proprietary connectors are involved. The only common issue is trying to charge a device that negotiates more than 15 W; the bank will simply limit output to its 3 A maximum.

Check your device charges at 5 V over USB-C

Before ordering, confirm the equipment you intend to power accepts 5 V supply via USB-C and draws no more than 3 A. Devices requiring higher voltage profiles or proprietary charging pins will not work. The banks measure 4.2 in by 1.0 in and weigh 4.3 oz each, so verify your pocket or pouch can accommodate that cylinder.
