    I like this portable charger. It came in handy when my electric power was off for three days and my neighbor let me use her electric to charge it up so that I could use my smartphone.

    I bought this for a co-worker. The one I bought for myself is the 20mAh pack. This portable charger is good especially if you need to quick charge your phone.

    Terrible power bank

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

    I would not recommend this power bank. Main reason it doesnt charge your phone fast at all, it literally takes hours to even get a charge let alone maintain the charge you have. The battey may last awhile but again you would have better luck charging it using via wall plug or your car port. Wouldn't recommend.

    Very powerful, and about the same size as the phone so it can be easily carried. Just be sure you have an additional USB cable to keep with it, as your other one may be left on the AC adapter!

    It works great, but it weighs a ton. It is not very travel friendly. I have encountered a new problem that makes the pack even pricier. The fact that it only has USB-A as an output source makes this battery way more expensive and it forces you to use old cables or buy extra adapters. If you are using newer technology that doesn't rely on USB-A tech, this is not for you.
