I keep a couple fully-charged to use as power banks during hurricane season each year. They'll recharge my cell phone, my iSticks, etc.
I'll bet there are at least a few members in need on here, who'd use them if you were PIFing them. I have a supply of NIB MVP2 kits, MVP20W mods, and MVP30W mods. Those suckers are well-built, reliable, and have pretty high mAh capacities.
This conversation spurred me to look for my old Smok Baby-priv with its beat up yellow ProTank tank, and I found it and one unused coil. The thing still holds a charge too. Into my stash it goes. You never know when it might be your last mod!
