So I got a cheap Buddee Big W $10 USB wall charger over a year ago to bring along with me everywhere I go in my cargo pants as I stopped carrying a bag awhile ago. It has been working perfect until recently the internals started short circuiting. Now I was trying to think what could have caused that and I remembered the past week I have been doing a lot of rough work and it took a beating in my cargo pants and I'm certain it was not built with that kind of protection so the internals probably got messed up inside even though on the surface it looked still fine.
So I had to throw it. Right now I'm using a new high speed QC3.0 rated 15-18w rated USB wall charger from Kmart but it was only $10 and I'm pretty sure not shockproof rated at all or waterproof.
So I'm looking for a relatively cheap rugged mainly shockproof USB wall charger now or at least one that can maybe take a beating. So I'm wondering if anyone has had this same problem and found a good product or solution. I guess I could just leave one charger at each of the sites I clean at but it takes up an outlet and some sites we can't leave personal devices plugged in or even around so trying to find a rugged shockproof solution before I accidentally short circuit myself. Or maybe the USB wall charger is as strong as I thought it was and an insect or piece of dust got in and shorted the circuit.
TL;DR any recommendations for a shock resistant USB wall charger bonus points if it is also water proof and dust resistant somehow but mainly just looking for shockproof factor
Thanks have a nice day!
