Another fan of Fantikk. I have taken mine (10" x 3") on several long distance trips over a couple of years. VERY reliable. When the battery indicator shows less than three bars, plug it in and in a couple of hours it will recharge. On trips, I check in at motel, unload stuff. kick back until dusk and then head back out with Fantikk and tool kit. Check tires, look over bike for any loose bolts or other issues, check oil, put everything away, wash hands and off to dinner.
