Good Idea Tested the charger on my LG Lucid. Phone started to charge OK, as normal. Have a rechargeable battery pack that I used, phone states on slow charge. Can not comment on battery life, good emergency charger. Noticed that the local Menards is carrying this charger. April 3, 2014
Works Awesome I have HTC One worked great for me when my phone needed a charge. I also purchased the 7 hour power pack too! March 29, 2014
Not a very good charger it works but did not realize that the battery would charge my Samsung SII just one time and that is all. I need to charge my phone up once a day. A person can spend a lot of $$$ just for the batteries. Granted the charger is very small and light to carry around..better than another charger I have but at least my other one can be recharged to use over and over. March 17, 2014
Good for emergencies This product worked with my windows 8 phone. I think it's a good item to have when you need to charge your phone and there's no outlet around. March 12, 2014
great Powered my phone a Samsung galaxy S4 very well so I would definitely recommend this product!! November 3, 2013
Didn't work We tried this on three of the phones that the box stated it would work on. None of them worked. It also doesn't work in an Iphone 5. The other model does work in an Iphone 4. I cannot recommend this product at all. October 6, 2013
