I saw this in boating mag & thought I would post it here for those cold mornings when your sled /car/ boat battery needs some boost to get you going & moving with little hassle. Very small fits in glove box or sled bag & charge lasts super long time without recharge. Nice saftey net & can run devices off it too. I have seen on the net for as low as $129. Let me know what you think?
