Cell Phone External Chargers for iPhone and Android by Juice Boost. Universal Phone Charger Power Bank. Smallest Thinnest Backup Battery - ON SALE TODAY

I expect to be completely satisfied with this little gadget but really wanted to review the seller - these guys excellently replaced the one I initially purchased when it arrived without the iPhone adaptor anywhere in my packaging or in the unit itself. I think that's very classy and would happily do business with them again. For now, I am charging the new unit and eagerly awaiting the chance to charge my iPhone on the go. Price, size and adaptability were the key features that made me purchase this product. Now I will also add seller reliability to that list.

I'm giving this a three because my first one, after working well for a couple of months, failed. But the company sent me a new one without any trouble, so that's good! I hope this one will keep working, because it's such a nice design - small enough to carry in my purse and handy to use when needed.

This only worked for about 5 charges. I did like how small and compact it was though.

This is the best. Have used it so many times to charge my Android & tablet...Fits right in a little pocket in my bag. Recharge is same time as when using ac adapter & it holds it's charge. ( I try to remember to check the charge every couple of weeks.) Recharging it takes a couple of hours. Buy this product...it will save your day & you can' t beat the price.

Was a bit skeptical when i received it. How could anything so small and simple really work. Well i was really surprised and happy. It is easy to use,, comfortable to take along with you, ( i travel for work so this is important to me) and it is powerful. This device charges quickly .Then charged my phone very quickly. It is not bulky and fits in anywhere. I highly recommend it.

Really cheap quality. Feels like a knock-off piece of dinky plastic. The cord being tucked into the charger is a good idea, but it doesn't fit neatly and is also cheaply made. Would not recommend.

Works great for about two full charges. Just enough to get me through my day. It doesn't heat up much and so i can just plug it into my phone and keep it in my pocket without any bother.

This is DANGEROUS! Amazon needs to recall this immediately. I charged it then plugged it into my phone. THE BATTERY STARTED MELTING! Stay away from this.
