This is one of the better compact external batteries that I’ve tried. It’s fairly capacious, reliable, and elegantly designed. The small digital display comes in really handy for discerning the remaining amount of charge, and faux leather makes it look and feel like a fairly sophisticated consumer electronics product.

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, when you really want to discharge them, the consumer electronics has become really robust in recent year. 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 4S, iPhone 5S, 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 iBucks fully charged battery. I was also able to charge two devices simultaneously.

To fully charge this battery it takes about five hours. This is somewhat longer than some other such batteries that I have tested, and I think this is primarily due to the fact that it relies on USB connection for powering. 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.

iBucks battery is very well designed and very compact. 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.

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.
