Xcellon 12,000mAh Power Bank with AC and USB Outlets

I have been using this as a supplement battery to my laptop while studying. It is nice to be able to sit anywhere in a coffee shop and not be limited to seats that have an outlet nearby. It also has a convenient USB charge port to charge your phone at the same time. Before you buy, check to make sure your AC adapter for your laptop is 65W or less. If this is the case, this will be a great addition to your mobile workstation.To Xcellon: For a v 2.0, keep this form factor, increase the wattage rating for the AC outlet, and get a capacity closer to 22,000+ mAh for extended use.

This is great. Used it for blowing up air mattresses and charging phones while camping.
