Wow, that's an interesting little unit! Would sure be easier to use jumping a bike or sled than jumper cables. Will be interesting to see how they hold up (since some of the various lithium battery manufacturers seem to still be working out the durability bugs on their lithium batteries). That DirtWheels magazine article was interesting in how many times they could jump start the atv and a pickup. Might be worth having one of these because I could carry it on the snowbike, snowmobile, ATV, sidexside, dirtbike, motorcycles and car/truck. Probably good for a boater, too. Thanks, bfly, for posting!
Yea, it is a pretty cool idea. I picked one up and carry it in the car most of the time (takes up less space than jumper cables). It will be in my pack for snow bike season and with me on motorcycle road trips as well.
One thing to keep in mind, since it is a LiFePO4 battery it has the same cold temperature issues as the LiFePO4 bike batteries. It is small enough to put in your jacket pocket to warm it up if needed though.
