    This is the BEST portable charger that I have purchased so far. I bought this for an 9 day international trip and this battery performed perfectly charging 2 cellphones and 2 iPad's for the whole trip without having to be recharged. Granted you will have to charge it completely before usage. It's a bit bulky and quite bigger than other portable batteries, but the power and long lasting charge is unbeatable. Even with it's "bigger" size it;s extremely easy to carry, it even comes with a nice pouch for storage. I can't recommend this enough for traveling!
