Great product - have been using as an external power source and have not had to recharge yet.

The product is heavier and bigger than I anticipated (check specs before purchase if that could be a concern) but overall and pleased it is bigger as it holds so much power. It is easy to use and move about to where you need to charge something. Relatively quick to recharge unit, or charge an item. Very good value for money.

Best power bank i've ever owned! No cons so far in the short time I've been using it.

Compared with the Xiaomi 20000 Powerbank about 3/4 of charging capacity. OK for the money.

The powerbank doesn't recognise when a low-draw device is charging. For example if my Bluetooth earphones are plugged in and charging at 0.5A, the battery pack won't sense it and will stop charging. But it charges my phone and tablet fine, since they pull 1A and 2A.
