    Easy to use, need your own cables, lasts a while. Is on the heavier size, but it’s also cheaper than lighter ones

      Hi JacobRomelhardt,
      Thanks for your thoughtful review! We're glad to hear the power bank is serving you well as a backup. The larger capacity does add some weight, but it’s great to know you found it to be a cost-effective option. For lighter travel, our slim 10,000mAh models might be worth exploring next time.

    Great product. I purchased this for a family trip. Charged it fully before we left and it was used daily by everyone. Wish it had more USB C outlets, but that’s my minor gripe. Great product.

    Bought this as a gift for family and friends. They seem to really like/use it!! I have one for myself and it works great! I like the battery indicator on the power bank itself, the USBC and USBA ports and the little handle which makes it easier to carry with you! Highly recommend
