    The bank doesn’t last long. I plug it into a hello watch 3 and it last two days. I have a cheaper 4000mah bank that i plug into the watch and it last about 14 days. I figured the name brand would be better in this case, not so.

      Hi VijaykumarJ,
      We’re sorry to hear the power bank isn’t delivering a full charge as expected. This model is designed to support moderate daily use, but if you're consistently getting less than a full charge, it could indicate a battery degradation issue or a technical fault.
      Even though it's a compact 5,000mAh unit, it should still provide at least one full charge for most smartphones. We recommend reaching out to our support team at https://support.energizerpowerpacks.com/ so we can help diagnose the issue or explore a solution.

      Dear Customer,
      This indicates that you are concerned about the power capacity and charging status of the power bank before your trips. Energizer power banks are designed to provide reliable power. To ensure it is fully charged, you can connect it to a suitable charger and keep it charging until the indicator shows a full charge.

    I bought both 5,000 and 30,000 based upon price (vs. my old Anker). The units themselves take forever to charge and are equally slow when you are charging a phone or worse.... a computer. If you are in a power pinch, these are unreliable to get the job done fast. Ditching them 3 weeks after purchase (no $ back from Best Buy). I can't take how poor these function. Going back to Anker at 4X the price.
