Innergie

It has been several years since I called USB the Universal Supply Bus and I'm happy to see how much improvement is being done in this area. Innergie is the new player in this field and takes the market by storm thanks to the no-compromise approach.

I report to be a very satisfied user of the dual - port 15W USB charger and the 3000mAh rechargeable emergency battery. Both share several common design goals:

• Output rating of 2.1A per port - meaning they will fast-charge the most power hungry tablets and smartphones (including the Galaxy Note II, the Google Nexus 10 and the iPads.
• Size / weight squeezed to the minimum 

I happen to travel with several USB - powered devices all the time. It is always the Galaxy Note II and then a smartwatch (the Pebble), a backup battery (the Innergie), a backup wireless data server (the AirStash), a portable WiFi AP (the Huawei hotspot). Therefore a dual - port, high output USB charger is a must and it has greatly simplified my mobile setup.

Having a 3000mAh of backup juice at hand anytime is equally important. I do not use it very often, but like a spare wheel, it gives me a complete piece of mind.

On top of the set, Innergie adds a universal charging cable, that works for all devices I have (although you may have to wait for the version that includes Apple Lightning.
