I've posted this pic before, but for the new members...if you happen to have a frame house and live in hurricane country, a good 18v cordless drill is a serious labor saving device if you board your windows with plywood... have a spare battery... but I have 27 windows to cover so use a Stanley "Yankee Screwdriver" as a manual backup...the spiral groove rotates the tool bit when downward force is applied... I have my deep discharge trolling battery on float charge, but give the Eneloops, Ridgid battery packs, and other 12v's a good charge at the beginning of the hurricane season, and again with an approaching storm
