I works a long side my longzoom samsung camera charges up external battery along with back up batteries for field trips and over nighters also works good charging my cell phone and tablet

We were just on a trip to the west coast where we used the charger on several occasions

I'm glad I picked up this item. Even though it doesn't have one of those fancy screens, it does exactly what i need it to do and I have no complaints. I just wish Best Buy would offer a warranty for it, I was really surprised they didn't and frankly upset about it.

Ok this thing is just a battery right? A couple of years ago I purchased a cheaper battery thinking there could not be that much to consider other than size. As my devices have become more power hungry that original device did ok, until I purchased my Mophie. This thing is massively better than my original! Charging, well instead of 10+ hours for a full charge it is very quick. It holds more than enough to handle my Note 5 a couple of times, keeping me charged for even the most demanding of days or weekends. Charging my device from the Mophie is pretty much as quick as using any other 2.0 Amp USB, so it is very fast. And it will handle 2 devices at once with no problem. It is a little big, could benefit from a case or some sort of rubber bumper protection but fits just fine in my gear bag. Build quality is very good, it feels and is substantial. Of course it is going to be a little bigger because of the amount of power storage it supplies. I will be purchasing another one for those just in case moments (yes I have way too many electronic devices) but I am really not in big hurry because this one is fitting my needs.

If you have an iPhone tied to multiple email accounts and text all day then you know your battery will be dead in a hurry. Bought this for a cross country flight and it was total overkill. Did not need a battery this big. Came in really handy when a few people had dead phones, took turns charging 4-6 different phones no problem (2 USB ports for double charging at the same time) probably would charge my iPhone 5 7-10 times from fully charged (maybe more, wasn't away from a power source long enough to completely drain it). Takes a few hours + to completely recharge though after you use it. Great battery, solid, well made, heavy, Smooth suede like surface.
