    SLOW TO TAKE A CHARGE BUT QUICK TO DRAIN

    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.

      Hi MysteriousWays,
      Sorry this power bank didn’t meet your expectations and that you’ve decided to return it. Your experience with the slow charging is disappointing, and we appreciate you sharing your feedback.

      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!

    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.
