Review on 🔌 FOBSUNLAND USB Wall Charger - 5V 2.1A AC Power Adapter for iPhone, iPad, Samsung, Tablet, Kindle & More (White 2 Pack) by Geoff Yates

Two of the four I ordered (the only two I've used so far) are not working properly. They seem to deliver the advertised performance, but after a while (hours or days) they stop delivering that charge. It is quite frustrating and confusing when a component of a complex charging system fails after it has already been tested. When the wireless fast charging failed, it took me quite a while to determine if it was my phone, the wireless fast charging device, the USB cable, or this adapter. I checked this last (because it was plugged in successfully before going live) and AFTER I had already returned the (probably) normal wireless charger. It wasn't until the replacement charger arrived that I realized it wasn't the problem and decided to double check every aspect of the system. Aggravating.
