Tekkeon TekCharge MP1860A Dual Port Power Pack for MiFi, Blackberry, iPhone, & More
[MP1860A]

I recently used the TehCharge for the first time and it worked wonderfully on my MiFi. My battery on my Ipod also ran out while I was on the road and i just plugged in the TekCharge and charged it right up. I would recommend this item fort anyone that is on the road a lot and may not have a chance to plug in somewhere. It was a life saver.
