Found myself in the pucker brush the other day and had left the dome light on in the truck for several hours and had a dead battery.
I did have a Bosh 18 volt lithium ion powered drill in the cab and having seen small jump boxes now being offered for sale I thought what the heck and with two jumper wires that small battery pack had
enough juice to turn over the truck and get me started.
I don't mind a walk in the woods as long as they are a planned walk in the woods.
