This is a fairly spacious and compact power bank/external battery. 8000 mAh is enough capacity to charge most smartphones three to four times, and to fill up most tablets to full capacity at least once. I’ve tested it with iPhone 6 plus, iPhone 5S, and Galaxy S3 and the battery performed as expected with all of those devices. The battery takes about four to five hours to fill up completely, and it charges my iPhone 5S in about two hours. Ideally you would leave a battery like this one to be charged overnight.

The battery is very compact and it fits comfortably with all of your other gadgets into a messenger bag for instance. It can even fit inside a large pocket, but I would not go around with it like that. It comes with a small USB micro cable that can be used for charging of the Android smartphones for instance. Unfortunately, it doesn’t include Apple charging cables and you would have to provide your own.

This power bank comes with several extra features, some of which are more useful than others. It has a nice LED screen which lets you know the precise amount of power that is left (from 0 to 99%). Most power banks, if they bother with something like this, only give you the power remaining in quarter of a capacity increments. A more precise gauge can really come in handy when you are traveling.

The other extra feature I am much less enthused about. The power bank comes with an LED light. I have never reached for a power bank to be used as an LED flashlight. You might have different experiences/expectations, but as far as I am concerned this is not the strong selling points of this power bank.

The two extra features that would actually be really useful in a device like this are: 1. Built-in micro USB/thunderbolt cable, 2. Built in power outlet prongs. These two features would ensure that you never have to worry about carrying all the extra cables with you. Unfortunately, I have only seen one manufacturer come up with a power bank like that so far.
