I took delivery of one of the TabletKiosk MP3400 battery pack units last week and have just kicked off a test that I think is going to last for nearly 10 hours!

I’ve connected it to a fully charged Kohjinsha SA1 which, with its 29W/hr battery, should last for about 3 hours in this test. The 56W/hr of the battery pack should, however, power it for 6 hours before the UMPC battery kicks-in.

The test scenario is fairy heavy on the battery as I’m running the Kohjinsha with 50% screen, WiFi on, no power-saving features turned on and its playing a 2mbps DivX non-stop. Under normal operation I get 3.5 hours on the Kohjinsha so that would equate to 10 hours normal mobility with the batt. pack.

After the test I’ll take some pictures and write a little report but so far I like what I have here. More details on the TabletKiosk website.

[Full disclosure: I received a small discount on the product.]
