    It's pretty decent. Overall, it doesn't charge as well as I expected, especially if you are using your phone as it charges. Says about 3.5 or 4 charges for my Samsung phone model but I usually get 1.9 or 2 charges before it's out.

    A full discharge-charge-discharge test with a USB power meter shows that the "10,000mAh" power bank unit I just received days ago has less than 6000mAh capacity - not expected from an Energizer product. Other reviewer have also mentioned this problem. This unit has good build quality otherwise.

      Dear Customer,
      The capacity you mentioned might be a misunderstanding regarding the rated capacity. The rated capacity of a power bank is typically lower than the nominal capacity indicated. This is due to factors such as energy conversion losses and the voltage differences in the charging and discharging processes. Energizer power banks are designed and tested to meet industry standards and provide reliable power within the specified rated capacity.

    Very easy to use and the digital display is extremely helpful. I got a full two and a half charges for my phone. It takes a little while to charge up fully but leaving it plugged in overnight does the trick.

    briefcase light as opposed to the 30,000 which I also use at home. Adequate to charge my iPhone and even run my 16in MacBook Pro for a limited time. Built like a tank. I does the intended job well
