For your lifestyle, a charger must be three things: tough, waterproof, and powerful. FUEL is all three:

This Power Bank Is Built To Last
It's built to withstand being knocked around in your pack. And as if that's not enough, it also has a built-in LED lantern with three modes (Normal/High/Flashing SOS) for your outdoor adventures.

100% Waterproof
This bad boy has an IP67 waterproof rating, which means that with the port covers closed it can submerge for up to 30 minutes without compromise

Easily Charge Any Small Device
And for USB-A and USB-C Power Delivery (PD) it cranks out 3.6V at 18W and 10,050mAh to easily charge any small device with the 3-in-1 MFi-Certified cable that’s included. That's Herculean power from such a compact charger.
