    This was great to charge two phones at once. Takes a long time to fully charge but it is great to keep 2 phones charged all day.

    This is a good battery that does not take up too much space when you need to bring it along. I am very pleased with how good it charges.

    I've been able to charge my phone multiple times off of one charge and it's still not even below half. Has held a charge for well over a month too.

    Takes a while to charge. Supports Samsungs fast charging. Has a 20000 milliamp hour battery. The only thing that can make it better, is adding USB C.

    Nice charger, with 20,000mAh, that will give you plenty of charges. Bit long and heavy. I also have the square 13,000mAh charger from Anker, which is smaller and lighter. Carrying case is nice, but the cinch strap was caught and I had to free it up by cutting part of it.

    Never worry about a dead phone battery again. Charged my phone and kids tablets multiple times before needing to be recharged itself. Great purchase
