I had the same experience. Bought a 6 port USB charger on Amazon, and randomly it would just shut off and need to be unplugged from the wall for ~10 minutes and then plugged back in. I emailed their customer support, and they just asked for my address and sent me another unit. Didn't even ask for the return. So seamless, and really made me a fan of theirs.
