or set it on percent, and when you see it get to a certain level like 75% or 50% do a recharge
it varies depending on your style of camping
the first day you might want to go about your normal USE routine, and then check the ah count and percent numbers before the recharge ?
we are heavy users and recharge every day, but you may not need to
