    This Dynex battery is great for on the go! No trying to find a plug-in. Just stick it in a bag or pocket if your battery gets low. It can completely charge my phone if it's almost dead.

    My phone never stays charged. This product keeps my phone charged when there is no place to plug in phone, i just plug in this charger to it and my phone is charged again. Great charger.

    charges devices in a quick amount of time. You will not get a device charged at 100%, but sure gets you out of an emergency when your phone or tablet is dead! Good product for the money

    Bought for my teenage son, who's phone battery would always go dead because he is constantly on it. Now he has no more excuses, especially when I call and he tell me his phone was dead.

    Charge stick worked well while we were out hunting without power. They allowed us to charge them in the vehicle then use them later.

    Picked up a couple of these on sale to keep in our cars for emergency and for our kids to take to camp. They are small and easily stored/carried. No problems recharging cell phones.

    My wife has been able to use it several times already when we are out and about. She can forget to charge her phone. Now it's just about getting her to keep it in the right purse.

    When you are running out of power and need to get a charge, just being able to plug this in and know my ipad or phone will continue to work is great. I can carry it in my purse.

    I use this product just about every day. It has been very helpful because I have been in numerous situations where there is no outlet to plug a phone charger into. This has saved me.

    Little device recharges quickly and hold charge until needed. Phone went from 10% to 70% in 4-5 min. Half the price of other brands

    First time I used it everything was great. Since then I'm having trouble with it. It only charges my phone (iPhone 5) for a few minutes before turning off. It may not be compatible with iPhone or it may just be my phone. Works fine with my tablet.

    Great little backup power source without an outlet. Recommend this to anybody who is always using their device and not having to be limited to how long the cord to the outlet is.

    I got this product for my mom since she replaced her old Nokia with an iPhone 4s. Of course battery life differs drastically between those models. As a result the phone would run out of juice most of the time. Pros: -Compact in size. -Sturdy aluminum body. (Always a good thing inside a purse) -Bright color. (Easier to locate in a purse) -Charges in less than 2 hours using a USB wall charger. -Auto cut off feature if not in use.

    I have used it only once yet. But it seems to do its job well enough. Haven't yet tried charging the whole battery of my phone, but looks like it could handle a complete charge.

    Very Disappointed

    I was very disappointed to find that the charger stays charged less than a week when carrying in my purse. It was not exposed to excessive heat or cold during that time. It is not much use to me if I have to remember to charge it every time I leave the house. Also, the USB does not make a firm connection with my new Note 4 phone so it looses connection and doesn't charge the phone. I didn't expect to get a full charge for the phone, but I did expect it to stay connected when left sitting on a table to charge. I realize the device was not very expensive but I certainly expected much more than I received. The best thing about it was the nice Amethyst color.

    Works like a charm - I travel several times a month. This fits well in any purse or backpack and helps avoid the now-routine mad scrambles for walljacks at airports and hotels.
