There is no shortage of external battery chargers on the market these days, and it can be challenging to find the right one for you. The two main features that distinguish Moonstone from the competition are its relatively small size and its fun colorful design. If you like to make a fashion statement with your consumer electronic devices, and if this kind of colorful design appeals to you, then Moonstone is a great charger to have.

I’ve used the Moonstone 6000 charger for a few days, and overall I am pretty impressed with it. 6000 mAh of charge capacity is enough to charge my iPhone two or three times, and to fully charge my first generation iPad 3G. This is a very light and well designed charger that easily fits into a compartment pocket of your messenger bag or a suitcase. In an emergency it can even fit inside of a larger pocket. It comes with a micro USB cable, which can be used for charging of various Android smartphones, Kindle book readers, or any other device that uses micro USB charging cables. Unfortunately, it doesn’t come with Apple’s charging cables, so you will have to use your own or the ones bought from some other manufacturer. The micro USB cable can also be used to charge the Moonstone itself, but you will have to either rely on another charger or use your computer for this to work. Moonstone comes with a nice carrying bag, with pockets for both the battery and the cable.

This is overall a pretty decent and nicely designed external battery, but it has its share of shortcomings compared to the other such chargers on the market right now. 6000 mAh is pretty much the low end of the capacity for such devices. Many of other external batteries come with Apple connector cables or attachments, as well as the ability to charge the battery independent of other devices. moonstone is also much more expensive than some of the other external batteries that I have tested. It is definitely a good product, but in comparison to many other similar products it leaves something to be desired.
