    Wireless Charge is good, is quick. The MagSafe isn't good (no strong). Sometime I could not charge with a USB C.

    It's just okay if you don't have a place to plug in a regular charger. My main issue is that it will only charge up to 75% . I have other power packs that will consistently give me a full charge month after month, year after year. I don't think it's worth the extra money over a regular power pack.

      Hi,
      This model offers a 5000mAh capacity and is designed mainly for quick top‑ups on the go rather than fully recharging larger smartphones. What you described matches its intended use. If your unit appears to perform below this expectation or has other issues, our support team can help:

    Its an ok battery bank, I bought it on price alone. Its as big as another bank I have from Anker but this one doesn’t allow you to charge it and a phone at the same time. For about another $10 you can get one from Anker that will but there is a price difference.

    The Energizer backup battery charger for my iPhone was a truly lifesaver during my recent trip to Japan. After numerous pics, videos, Use of Google maps, my iPhone ran out of its normal battery power and I used the charger to power my phone afterwards which allowed me to be stress free the rest of the day.

    Energizer Power Bank

    The Energizer Power Banks are excellent for the price These power banks will charge one or two times before getting depleted. The mag safe charging is easy and works well. You can also charge using USB C or supplied USB A cable. This power bank does not take a lot of room so they are easy to carry with you. I found that two of these are cheaper and easier to take on a plane than the physically larger and higher powered banks.

    This product does not hold charge as advertised. It is better to us a higher capacity battery to keep your MAX series phones. I am not impressed by the magsafe magnet quality as it often detaches itself from the phone. I wish I could return this sooner.
