    This device is great...I am able to use in on my overnight job when battery gets low on my cell or even charging my case for ear buds. Great Price.

    Works great and charges as expected. Only drawback is sometimes the battery pack itself doesnt charge but thats rare. Overall great product. Also a little heavy and big to carry

    This portable charger is pretty great. It charges my phone just fine. The only thing is that it takes a few hours for the portable charger to charge and it's a bit heavy. Overall it's good.

    Product worked fine but I was not impressed with it's bulky size. I returned this product for a slimmer and lower priced charger that works even better. Simply too big.

    Good Value for the money. The review that states it is not a 20,000 power box is wrong. It is 2x10,000 which is 20,000 of power.

    Easy and fast charging of the battery. And it charges your devices pretty fast as well but only of you have a good charging cord.
