    I had not seen this size Dynex charger before, but had to buy it because of the extra power. Great portable size and can charge your phone faster than charging from a brick. Super Buy.

    This is a good item to have in you don't want to plug phone into an outlet. It would be better if it was a little smaller, but overall it a good value.

    This charger is great! I had one before that didn't work correctly after about a month and a half of use, however, this one is still going strong! The charger fits in practically any bag and is easy to take with me. I typically don't use it until my phone is around 30-40% and charges it up to 90-100% every time. The one downfall is that I have to charge it after every use, however that isn't really that difficult to do.

    Charges quickly and lasts a while on one charge. Plugs right into the outlet that I charge my phone on so it’s easy to keep up with it.

    great portable battery for cell phone

    It works great for a quick backup charge but if your a heavy cell phone user than I would advise to get a more expensiver or one with a higher volt intake/store. This one can fully charge 1 andriod phone. Other chargers have different quantity of how many it may charge given how many volts it can take or store. Again, if your a heavy user and you have a family of 3 then I would advise a higher quality charger but if not then this charger would work well for you.

    My daughter uses this all the time. She is on the go with school activities and sports non-stop so having her phone fully charged and ready for use is really important to staying in touch. All kids should have one of these, at least for emergency use, in today's smart phone world.

    Very nice and portable. Plus it really does work and it doesn't take that long to charge either. The USB port allows for all cellphone, iPod, iPad iPad, and other electronic accessories that have a USB cord to charge in a most efficient and rapid way. Thank God some invented this portable charge because I'm not always near a wall socket or a car charger. Very good to use when there are natural disasters or other emergencies arise and there's no electricity to keep a cellphone charged. This product should be put in survival kits and the Red Cross should implement its use. This product may save someone's life some day due to keeping the lines of communication on and open.

    It does exactly what it says it will, provide a quick charge when your device battery is dead. It will not completely charge your device, nor is it good for more than two charges before needing to be recharged itself. However, when you need your phone in an emergency and it's dead, this will do the trick (provided you remembered to charge the stick).

    I bought this product because I sometimes find myself needing a charge when walking in the park or the beach. I like the fact that I don't have to stress out that my battery on my device will soon go dead. When I only have 10% battery life I charge it on this personal charger. It is only good for one full charge though. I don't mind that at all.
