I like the cheap ones since I can leave it untended on the bike for worry free hiking. If someone takes it no big deal. If I had the expensive model I would either have to worry or carry it; both options detracting from the primary goal of having fun adventures on the TW. Smart operation eliminates concern about overheating and a possible short duty cycle since I only use it on a motorcycle. Just a few minutes does the job.Thank both gentlemen.
We're hijacking the thread here a little but I'm tempted to figure out whether or not I could wire in an extra battery for when the system is perhaps overcharging a bit. Could be useful for a variety of things at camp with the right wiring. There are different ways of doing this but I dunno much about modern batteries. More research is required.
