The bottom line on the Onite Power Bank external battery is this: it works. In the past I’ve tried several different reserve power supplies for my gadgets, and I have not been impressed with many of them. However, this Onite battery really lived up to mu expectations. In fact, in terms of the combination of price, capacity, size and design it might be my single favorite such battery.

In order to test this battery charger I decided to completely drain my small electronic devices so that I get as clean of an idea of this battery’s efficiency as I can. (As an aside, the consumer electronics has become really robust in recent year, especially when you really want to discharge them. It took me much longer than I thought it would. I had to blast music from my iPhone for hours and hours …) I discover that I was able to fully charge all of my small electronic devices with plenty of power to spare. Full charging usually takes between one to two hours. I’ve tested this battery with iPhone 5S, iPhone 4S, Samsung Galaxy S3, Kindle Paperwhite, Mobee Magic Bar, and Jabra SPORT Bluetooth Stereo Headset . Finally, I’ve done the “iPad Test”: I tried to fully charge my iPad (First Generation) (32GB, Wifi + 3G), and I was indeed completely successful in that regard. Oftentimes I was able to fully charge two or three devices with just one Onite battery fully charged. I was also able to charge two devices simultaneously.

To fully charge this battery it takes about five hours. This is somewhat on par with the other similar batteries that I have tested. The best way to charge this battery is to leave it plugged in overnight. You can plug it into your computer or a stand-alone USB charger.

Onite battery is very well designed and very compact. It’s slightly thicker than two iPhone 5/5S, and about as long as those. It looks very elegant and sophisticated, and it is not out of place even with the most fancy consumer electronic devices. It’s also fairly light, and overall very convenient and portable.

The battery comes with a whole selection of different attachments, and they can be used with almost any small electronic device on the market. There is also a small bag that can be used to carry the battery and all of the attachments as well.

Overall, I am very pleased and impressed with this battery supply. It is effective, portable, and very affordable. I would recommend it to anyone who travels a lot or uses their gadgets on the go all the time.
