      Hi Sarge,
      We’re sorry the battery life and weight didn’t meet your expectations. The MAX 20,000mAh power bank is designed for extended capacity, which makes it heavier than smaller models. Actual usage time depends on the devices being charged and their power draw. If performance feels unusually low, please contact Energizer support for troubleshooting or a possible replacement:

      Hi EIET,
      We’re sorry the size and charging time didn’t meet your expectations. High-capacity power banks like this 20,000mAh model naturally take longer to recharge and are heavier due to the larger battery. For faster recharging, use a QC 3.0 or PD adapter to maximize efficiency.

    Seems to charge pretty slow. Also takes 10 hoirs to recharge. Finally, it only charged 2 ipads and 1 iphone before it ran out of juice. Maybe be all normal just not up to my expectations.

      Thank you for your feedback! We're sorry to hear that the power bank's performance was not up to your expectations. The recharge time for a large 20,000mAh power bank depends heavily on the wall adapter you're using. For the fastest results, we recommend a high-wattage adapter. Regarding the number of devices you can charge, it's a common misconception that a power bank's capacity is fully usable due to power conversion loss that occurs during the charging process. If you feel the performance is still significantly lower than it should be, please visit our support page at https://support.energizerpowerpacks.com/ and fill out the form so we can assist you directly.
