    Out of the box this product had a 76% charge (it's not rechargeable). So I returned it.

      Hi MariaC,
      If the LCD display doesn’t change during charging, it’s often because the internal battery gauge needs recalibration. This can happen when the battery hasn’t gone through a full discharge and recharge cycle. To correct it, use the power bank until it’s completely drained, then recharge it to 100% without interruption. This process helps the display accurately reflect the battery level.

    The power bank works great. It is a bit heavier than average, and takes longer to recharge (you can only use a 5V wall adapter). The usb that came with it, doesn’t work. Tried reaching out to the Energizer MAX company about it via e-mail, with no response for 5 days, now.

    5 stars for capacity and price, 1 star for charging speed. This device took 2 hr 45 min to charge my phone WHILE OFF WITH 0%!!! I have since ordered a proper power bank which charges my phone in 1 hr WHILE USING! If all you car about is capacity and not charge speed, then buy. This powerbank DOESN'T SUPPORT SUPERFAST OR FAST CHARGE!!!

      Hi AAceP,
      Thank you for sharing your experience. This model prioritizes high capacity for extended backup rather than fast charging, which is why it doesn’t support superfast or PD charging speeds. If quick charging is essential, a power bank with PD or QC 3.0 technology would be a better fit. We appreciate your feedback and will share it with our product team for improvement.
