This is a good product, but not as good as others
June 11, 2018
I bought the Anker PowerCore 10000, One of the Smallest and Lightest 10000mAh External Batteries, Ultra-Compact, High-speed Charging Technology Power Bank for iPhone, Samsung Galaxy and More because I couldn't find the older model I purchased a few years ago. I bought the Anker brand because I'd been so pleased with the first one. They work great with any battery powered electronic product that charges via USB - phones, tablets, WiFi speakers, etc. This model has only one output, but, according to the specs, can charge a smart phone two to three times before going flat. I really doubt I'll ever run it flat because my usage isn't very demanding.
So, why only three stars if this charger has so many great points? I found my first one (DOH!) so ran some head to head tests. This newer model takes twice as long to charge as the older one. Its output is limited and takes twice as long to charge up a phone or tablet compared to the older model, and the older model has two outputs to charge two products simultaneously. This is a good product, but not as good as others.
