Review on AILKIN 2-Port USB Wall Charger: Fast Charging 🔌 Block Cube for iPhone, Samsung, Google Pixel, and More! by Bryan King

Excellent chargers. They are compatible with any device that uses USB. Everything I got was fine. I will probably buy more. The only caveat is that 2.1 amps is COMMON. Since phones are typically 1 amp and tablets are 2.1 amps, if you need to charge two devices and one of them is a tablet, they will charge more slowly. For example: - a phone = max charge - a tablet = max charge - phone + phone = max charge - tablet + phone = slower charge - tablet + tablet = slower charge I hope this helps.
