This one's not stealthable, but just got off the phone with the rep at the company and it has a whopping 11,000 mAh at 5v!

This one's more stealthable, and still has 3400 mAh:

I'm doing the exact same with my MR-1...
I'm a bit confused from the page - can it provide power to say, the mini-usb on my Microtrack 2496, or must you use one of the regular round dc connectors it comes with?
Similar question: someone gave me a LilSync 4 AA pack that takes either alkalines or NiCad (according to the Web site). The retractable cable he had with it is usb on one end, but some sort of specialized connector on the other end (wider/flatter than USB, and locks into place). Can I get a LilSync cable to use this pack with my Microtrack?
Interestingly, I tried hooking up the LilSync pack to my Microtrack using a conventional USB cable plus an a Radio Shack adaptr to get to the right mini-usb size, and nothing! No juice from battery pack to Microtrack. Does this pack really only work with LilSync brand cables? Bizarre!
Sorry for the really beginner type questions - I'm not at all a IDIY type.
thanks
