Posted .Hi JaimeH,
Sounds like your power bank took an unexpected dive! We're glad to hear it kept working after drying out—that’s impressive durability. Still, we recommend keeping it away from water to ensure safe and reliable long-term use.

Posted .Hi M3tr0d0b3b00min，
Thanks for your feedback. We're glad to hear the battery life meets your needs. Regarding the slow output, this model supports up to 30W Power Delivery, but actual charging speed may vary depending on your device and cable. If the performance feels unusually slow, we recommend checking with a certified PD cable and adapter. For further help, feel free to reach out here:

Works well but the strap broke after 2 months
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I contacted Energize customer support and have not heard back yet
I would recommend this to a friendWorks well, I like it.
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Works for my phones, iPad, Apple Watch, AirPods, and other such devices. Did not work on my laptop but I don’t believe it is rated to do so, so not a negative comment, just an observation. Can take a while to charge. I like it.

Posted .Hi Xtorn，
Thanks for sharing your thoughts. We understand how important fast charging is, and we're sorry this didn’t meet your expectations.

it’s ok
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.It’s works but take too long to charge up to use and big
No, I would not recommend this to a friendBrand response from Energizer PowerPacks Service Team
Posted .Hi Chany,
We’re sorry the charging time and size didn’t meet your expectations. High-capacity power banks like this 30,000mAh model naturally take longer to recharge due to their large battery. For faster recharging, use a 30W Power Delivery adapter and keep the unit in a well-ventilated area.

Its either deffective power bank or its bad
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Honestly, it was OK at first, but then when charging all the way up to 88% reached and never filled up to 100% was kind of confusing. So I decided to take steps to fully drain it and recharge it but its charging speed is even slower than ever not sure its gonna reach 100% might be a deffective power bank.

Posted .Hi IvanD,
Thanks for sharing your experience. It’s unusual for a power bank to consistently stop at 88% or slow down significantly after a full drain. This could indicate a calibration issue or a potential defect in the battery management system.
We recommend reaching out through https://support.energizerpowerpacks.com/ so our team can help diagnose the issue or arrange a replacement if needed.

Had to return
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I was not sure if this was brand new or used. It was on 0% when i got it and did charge it to 100% and I thought it was great but when it was 80% left and it quickly went to 0% and died. Had to return it. Power banks aren’t supposed to be that way

Posted .Hi Demon,
We're sorry to hear about your experience with the Ultimate Lithium 30,000 mAh Power Bank. A sudden drop from 80% to 0% is definitely not expected behavior, and we understand how frustrating that must have been. Since you've already returned the product, we appreciate you taking the time to share your feedback and apologize for the inconvenience caused.
If you ever decide to try another model or have questions about our products, we're here to help.

I returned it
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This was likely a previous return. It wouldn't charge higher than 83%
No, I would not recommend this to a friendBrand response from Energizer PowerPacks Service Team
Posted .Hi Arizona602,
When a power bank stops charging at a certain percentage like 83%, it can be due to how the battery management system balances and protects the cells. Sometimes the system reduces charging near higher levels to prevent stress on the battery, which may make it appear as if the charge is not increasing.
