Posted .Hi JonathonC,
Thanks for sharing your feedback! We’re glad the battery life meets your expectations. Charging speed can feel slower because this model prioritizes high capacity and universal compatibility over fast charging. For quicker results, using the USB-C port with a high-output adapter is recommended.

Powerful but Huge and Heavy
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It works great but man it’s way tooo heavy. Wouldn’t say it’s perfect to take to festivals or concerts. But great if you traveling

Posted .Hi ManpreetD,
We’re glad to hear the power bank performs well for you. With a 30,000mAh capacity, the larger size and added weight are a tradeoff to deliver extended runtime and the ability to charge multiple devices over longer trips. That’s why it tends to feel less practical for festivals or concerts, but more suitable for travel, road trips, or situations where access to outlets is limited. If portability is a priority, a lower‑capacity model may be easier to carry day to day.

Not the best, not the worst.
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Works good for charging devices but takes over a day to fully charge itself. I’m not sure if I got a faulty one but it serves its purpose. I do like the 3 outlet options. It is also quite heavy.

Posted .Hi Lovemycoffee,
Thanks for sharing your thoughts! We're glad to hear the performance meets your expectations. While the 30,000mAh capacity offers extended power, we understand the trade-off in weight can affect portability. For lighter travel, you might consider our 10,000mAh or 5,000mAh models—they’re designed to be more compact while still delivering reliable power.
Let us know if you'd like help finding a better fit for your needs!

SLOW TO TAKE A CHARGE BUT QUICK TO DRAIN
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This product is painfully slow to charge out of the box and even after two or three subsequent uses. It can take up to 12 to 18 hours to charge up to 100% from a zero to 10% battery capacity. I purchased two of these batteries and had to return one and will return the other. Price was a factor in the purchase, but you get what you pay for. I will choose a more expensive battery, but with a better track record.
