    Initially i wasn't sure of my purchase, but after using it so many times to recharge my phone and other devices when not near an outlet, it is an amazing product. I especially like the fast charging port.

    All the equipment have one excellent cuality in all the locations. No difficult to used and different colors option, but all the locations maybe could have the same good attention. Some time we need to wait so long for orientacion after buying the product.

    It does not hold a charge long. I can't even get two phone charged out of it. I can't only charge one phone; after that, the energizer battery needs to be recharged.

    This is my second portable charger that I have bought and I love them! I had to get an additional one due to other devices that I started traveling with. Great item for the price.

    Handy! I wish the charging port could be through the Micro USB port since I do not use that for any devices. The USB-C cable for charging is not the most sturdy and the male male fall off/out of the cord if you aren't careful - happened to me.

    Sturdy build. Variety of charging ports for Apple, Android, and USB - C. There is a Micro USB cable included to charge your Energizer Ultimate Power Bank. I take it with me on road trips or while at grand kids outdoor/indoor sports events.

    I've only used this battery once (just bought it a couple weeks ago), and it did its job. However, the sealed package was missing one of the two cables claimed to include, so I had to use one from my previous battery.

    It does just what I wanted. Large capacity to charge several devices at once (both Android-based and Apple) but within TSA limits to take on the plane. Made good use of it on a recent road trip.

    We bought the Energizer to have when we take vacations. We have tested it making sure it is reliable. It has passed our tests and we feel confident the Energizer will serve a very good purpose.

    Solid battery charger with support for fast charging and apple products. We needed to charge a wifi hotspot and 3 devices and it worked fine. It was just a little bigger than I thought.

    Bought for the wife, but I use it too. I like that it has dual usb connections with one being a lightning connection. Heavy but durable, going strong after one year.

    Seems to work as designed. It does charge a little slow on my new phone. It will shut off as soon as it reaches 100%. This replaced an energizer 10000 that blew up on me one day when i plugged it in to charge

    Works really well and can quick charge any newer device in a jiffy. Like the option for a usb-c port for both in and out charge. It’s worth the money in my opinion.

    These are my favorite portable chargers by far. The only downside is they arent water resistant so you have to be careful. Other than that they're awesome
