    Very pleased with this portable battery charger. It does take a while to fully charge, but it holds the charge forever and is easy to use. Good to have on hand in case of power outages.

    Definitely a lifesaver. It's not too bulky and very easy to use. I like that it has different ports and charges my devices rather quickly. I guess it would help my battery if I didn't have 20+ apps open throughout the day, too!

    I bought this to power a light under a nativity display so no extension cord would be needed (a trip hazard) and it did just wanted I needed. I was pleasantly surprised to find it came partially charged. While I did charge it up, I probably didn't need to for that event.

    For the price point, its the best money can buy. Works well, takes a charge kinda slowly, but can fully charge up to 3 phones on one charge. Perfect for traveling on airlines as well.

    I have had this product before but an earlier version I think, or something different about it. I am on a trip out of state and forgot mine so bought another. I was confused about the 100% display. Mine was 76 when I bought it and I couldn't figure out how to fully charge it. It just wouldn't go higher. Finally I changed a cord and it worked. It stays charged when I don't use it so that is good. Now I grab it when I leave home in case I need it. I love the product.

      Hi outstanding88,
      Glad to hear you’re enjoying the product again! It sounds like switching the charging cable made all the difference—sometimes a low-quality or incompatible cable can prevent the power bank from reaching a full charge. We're happy to know it's now working reliably and staying ready when you need it. That kind of grab-and-go confidence is exactly what we aim for.

    Amazing Portable Charger

    This is one of the best portable chargers I've purchased. I performed a test on it with all of my devices and what it was able to charge before it needed to be charged was good. I'm able to fully charge my iPhone 14 Pro 3x on one charge. iPad 2x on one charge. It's inexpensive a great accessory to have while traveling.
