An adjustable weather resistant belt that allows Anker PowerCore and cables to be carried around. After being in lockdown for 2020, I can imagine people wanting to be outside for days. Imagine being able to carry 3 or 4 PowerCores and cables (protected by the weather resistant belt) to keep your electronics charged. Great use to hikers, boaters and campers.
Sounds like a good idea. You can always get a fanny pack
The humidity is why not, the sweat off the human around that body area will corrode and eventually make the Powercore unsafe.
I keep a Powercore 10000 PD (so a thin slab shape) in a waterproof bag (designed for phones but correct size) in a hip bag.
A small backpack would be ideal too
