    This battery pack is so great I never get to use it! Every time I get it charged up, somebody else takes it to work or out with friends. I think I’ve had the pleasure of using my battery charger once or twice. My recommendation is if you buy it buy more than one, so you might actually get to use it.

    The size is slick, the texture on the body of this charger feels nice and well made, it can charge up to 2 devices at once, and with the capacity you could easily charge up to 4 or 5 devices before charging it. Specially for the "Sale price of $20"

    Solid charger in a small package. Got this to help facilitate the use of a dash cam. My car didn't come with one of those powered mirrors, but I don't care to run a lot of wiring. I figured this just might be a great option. Light enough to attach to the sun visor. Hopefully, it proves as a viable solution.

    This is a very good external charger. It’s slim and lightweight, and fully charges my phone once, starting at 20-some percent. It doesn’t provide multiple charges like my Anker external charger does, but it’s easier to carry around.

    The best charger from Energizer. I always trust in to the company for all battery products. I got two on the black Friday with best deal. It's worked well so far, and there's not any problem. I will buy others next Black Friday if best buy will drop them with the better prices. Thanks

    Great Economical Power Bank

    Good source of power if you need it in a pinch. Charges up pretty quickly, will last 36 hr of charging a phone, and has multiple inputs for different devices. Nice deal for the price. Charges at 5V, not 12 so if you need it for something that requires more than 5V, this won't work.

    It comes charged enough to charge your phone to about 50 percent. It charges quickly its self and is compact enough to carry around in your pocket. Great purchase for an affordable portable charger!

    This power bank lets me charge my phone on the go. It has come in handy on trips and during the recent winter freeze in Houston. It charges pretty fast too. My fiancée bought one and I was always borrowing his. So glad I finally bought my own. Great product and I highly recommend.

    Grabbed to use at Disney so we didn't need to recharge our phones etc. Good life on the battery but a little slow on the charge but better than what I was anticipating. Wish they had the option to charge from USB c port as well as the USB a ones.

    Seems to do the job. Only problem is that it is so slim it it easy to misplace - particularly considering the color. Would prefer that something a bit more visible color-wise were available (Yellow, Orange, etc)
