We have a small, 4xAA powered USB charger, for making sure we have juice for at least one phone when we're off the grid. It works well for that intended purpose (emergencies) and we're definitely keeping it for hiking trips and such, where weight is a consideration. But for non-emergency use it's obvious we gradually need more and more capacity, and current too. Plan right now is to get around 10 000mAh of capacity at minimum, and it should be able to output @ 2,1A instead of (or in addition to) 1A. Because we will be using it outdoors, I'd like it to be rugged and at least splash proof. An actual proper IP rating wouldn't hurt.
As I run through the list above, Google starts showing fewer and fewer results. It seems there's one water resistant design sold under many brand names, here's an example:
Water Resistant 10,000mAh Power Bank | Brown Dog Solar
and even that doesn't provide the 2,1A. If I drop the splash proof requirement, I have dozens of models to pick from. Soo, please tell me what you bought and why you bought it.
