You can tell when a device is well-made if you're still using it years after first picking it up – even more so in the tech world, where redundancy and decline is a bit of an unavoidable menace. I don't have all that many gadgets I still use five years after buying them, but that's the last time I bought a power bank.
It was a 20,000mAh RavPower battery, chunky but with enough charge to rely on, and I've never replaced it. In that time, though, I've started to resent how heavy it is in an overnight bag or weekend suitcase – so it wasn't hard to blow me away when I got hold of a far newer 10,000mAh alternative from Anker.
