    It gets a little hot for my liking, it was bought for my son, it works though. It provides the charge he needs when he needs it. It’s small enough that carrying it isn’t bothersome. All in all, I give it a thumbs up, I just wish it didn’t get as hot as it does. The price is good for what it is too. I’d recommend.

      Hi SammyBono,
      Thanks for sharing your thoughts! We're glad the power bank delivers reliable charging and is easy to carry. Regarding the heat — some warmth is normal during wireless charging, especially with compact high-output devices, but if it ever feels excessive, we’d be happy to check it out. You can reach us at https://support.energizerpowerpacks.com/ for assistance.

    Charging really quick. Only con is if you have a very protective case, you'll have to remove it to charge without the wire connection. And most of the time it will take a long time to remove the case just to charge it wireless. Also like that it's small and lightweight to carry in a purse or in a coat jacket.

    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.

    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.

    Energizer Power Bank

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    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.

      Hi YingC
      Thanks for your comment. We understand that pricing is an important factor. While there are higher-capacity options available elsewhere, this 5,000mAh model is designed for portability, MagSafe compatibility, and fast 18W output — features that often come with a premium. We’ll continue working to offer better value across all our products.

    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.
