    Awesome charger for on the go needs. I love the fact that it has a USB-C charger and 2 USB charging ports for whatever devices you have. It’s also incredibly fast charging for my iPhone 12 pro max.

    this is a fantastic way to charge your phones on the go I love the fact that it is capable of charging two devices that require USB input. It’s not very heavy and can store while in a backpack.

    I bought this for my daughter who is always letting her phone die in the middle of a conversation and at times she has no charger with her to plug it in so I got her this and this is a lifesaver.

    Bought this for the long gaming days (board games) where I need to leave my phone on as I use an app to supplement the games while playing. I have used it a few times to just recharge my phone and laptop as well.

    The battery was great while on an extended trip as my phone battery doesn’t hold a charge for a long period of time . It saved me from always having to find a place to charge my phone. Being compact it was easy to carry around in pocket .

    The Energizer was exactly what I needed to be sure that my phone battery would not give out on me during my trip. Provided 3 recharges for my phone with one charge of the protable Universal battery.

    Works as expected. Also retains a charge for quite some time. Used it. Recharged it. And left in drawer for many months. Used again and it held most of that charge all that time.

    I was traveling by plane. I have an older phone that doesn't hold that much battery power. For the flight home, I was able to watch a whole movie because I had the battery charger. It was easy to charge and easy to use.

    This is by far the best portable battery I’ve ever purchased. It fully charges my phone (from less than 10%) at least 3 times before ever needing to recharge it! I highly recommend this!

    Compact, fast charging, good to have on hand for when you run out of power on your device. Not sure how many days it will hold a charge. Overall, a good item to consider. Other, larger capacity models are available, too.
