    Poor Qi charger

    I bought this item as a portable wireless Qi charger for my Iphone. First, the exact connection-location between the charger and phone is very precise and limited and is hard to find. Also, the charger surface is slippery, so when i find it I have to tie the two items together with rubber bands to keep from losing the connection. After charging for a very few minutes (<5), the Qi cuts off, so the button must be pushed again to restart it. It works fine as a wired charger, so i will keep it for other purposes.

    It Doesn’t Come With Everything You Need

    When I opened it, it had about 75 Percent charge on it. I gave this three stars because when I needed to use it, it doesn’t have everything you need to plug it in and charge it back up. It needs a universal USB AC adapter and that is not included I didn’t notice that when I ordered this. It will not connect to the one I have.

    No, I would not recommend this to a friend

      Dear MsMarg,

      We are sorry for the frustration and inconvenience caused by the lack of an AC adapter in the package. You are correct that a USB-C PD adapter is required to charge the power bank and that it is not included. While we strive to provide all necessary information, we understand how easy it is to overlook. We apologize that this caused you an issue and hope you are able to find a compatible adapter soon.

    I was about to return this power bank because it gets warm every time I charge my iPhone, and it’s a bit too heavy to carry in my purse — not the most convenient for travel. However, it does charge my phone well and performs reliably once connected.

      Hi AnalynH,
      Thanks for your honest feedback. We’re sorry the weight and heat during charging made it less convenient for you. While the power bank is designed for high-capacity performance, we understand portability and comfort matter too — especially for travel.
      If the warming feels excessive or you're concerned about safety, we recommend reaching out via https://support.energizerpowerpacks.com/ so we can take a closer look.
