Universal Backpack Power Strap

The M-Edge Power Strap adds a 3500 mAh power bank to almost any backpack or shoulder bag. Its adjustable design secures to existing straps without tools. A 2.0A output charges phones and small tablets while you move. Integrated LED indicators display remaining capacity at a glance.

Replaces Separate Power Banks

Instead of carrying a loose battery pack and cable, this strap keeps the power source attached to the bag. The jump is worth it when daily commutes or travel leave no wall outlet within reach. Reflective trim and a built-in LED flashlight add night visibility that a standalone bank lacks.

Sustained Output On The Move

The 2.0A port delivers steady current for the duration of the 3500 mAh capacity rather than a brief peak. LED indicators let you monitor depletion in real time so you can ration power across multiple devices. The strap distributes weight along the shoulder for comfort during extended use.
