Good on them for being willing to admit a mistake.

Mark,
I have had bad luck with portable USB 5vdc chargers. I sent for a ( marked Samsung ) 20k mAh charger and though it took a charge it had no output, so of course I took it apart.
First thing I found was the batteries inside could not physically put out more than 8k if it worked!
It was not worth the cost to ship back to China.
So I bought a USB Buddy from PowerWerx. This Buddy will take 10 - 32vdc input, and outputs clean 5vdc at 3 amps! I can run it of all the different batteries I own. Li-ion from my drones to a lighter plug hack I made for my car.
Did I say it icharges at 3 amps? Fast charging indeed.
