Hi guys,
So this may be a bit more off-topic than usual but here's my dilemma. I have a video camera that records in full HD, nothing special about that right?

The problem is, the battery drains A LOT faster than I feel it should. Even with an upgraded mAH battery I'm lucky to get 40-50 minutes out of it.

So then I started thinking about battery powered USB chargers and how my camera powers through USB. I'm fairly certain most "normal" ones are for smaller devices like phones... but I don't know, maybe one would work.

Anyway, I was wondering if anyone knew of a battery powered usb charger that might be strong enough to power a camera?

My goal (or idea rather) is that I could run it on a device like this and it might buy me 10-30 extra minutes and then it should switch to the battery. And huge plus is that I can easily switch out the batteries that are in the usb charger themselves.

Any advice or tips would be appreciated, unless you're going to tell me "buy a better camera"

    underthegun,

    igo, and probably others(I BELIEVE RAYOVAC) make "universal laptop batteries". The one I have is about 20,000mah. That is enough to have my upper end laptop running full bore for over 3 hours on a dead battery. The one I have goes between the power cable and the power end for the laptop. So it isn't actually INSIDE the laptop.

    The igo has a STUPID "feature". You have to press the test button to turn it on, and it stays on while there is a load.
