A great product for my uses 
This has paid for itself. I have used it now for 2 years to run fans and my credit card machine at outdoor art fairs where there is no power. At home I have used it for other things, to jump the car battery, pump up bike tires, top off car tires, and even to power the sump pump during a torrential rain storm accompanied by power failure. That alone saved my carpeting, as the rainfall was so great my installed battery back-up for the sump pump could not handle it. It does exactly what I bought it for, and more. It is ridiculously easy to use. There was a problem with a broken jack when I got the unit, but Amazon replaced it promptly.
Multi-purpose Powerpack
This is my second purchase of this item. It is really useful, whether inflating flat tires, charging a dead car battery, or powering a fan or TV at the football game. I am sold on this back-up power source.
Better than Described!
I was so pleased with my first unit that I purchased two more. I own five 13Watt solar panels and each Powerpack 400 can be fully charged with a single 13Watt solar panel. I only had to solder Radio Shack plugs to some braided hookup wire. This is covered in the instruction manual and is really easy to do.
The Powerpack batteries are cheap and easily user replaceable. Additionally, I can hookup larger amperage batteries (using the supplied jumper cables) to the Powerpacks - thus increasing running time on each unit.
Since my Radio Shack battery charger (for 9Volt, AAA, AA, and D size NMh batteries) functions with a 12Watt DC current, I can use the Powerpack to charge these little batteries when the grid power is down.
Saved the Day 
This thing saved me! I was 400 miles from home when my battery died. Luckily I had the portable back-up power source to easily jump start my car. What a relief. Absolutely fabulous for running a blender while camping but couldn't handle the electric coffee maker (probably due to the heat element). I would definitely recommend this product.
