If you are in the USA that is not going to happen. Sorry. NO charity capable of issuing a tax legit "vape gear 12K donation" no longer exists. If it's old enough, it might meet the exemption box as being before the deeming date. HOWEVER that does not mean Goodwill is gonna want your gear (Especially with COVID) let alone issue you a 12K DONATION receipt in one receipt that you can use to deduct on your taxes.
The best you are going get is selling it on the classifieds, and taking a hit monetarily and doing the effort of listing it. If it's a bunch of smaller items you may well get away with a smaller or no tax hit because frankly you are not going to get what you PAID for it. It's old. It's used. It is also (IMHO anyway) a shot here at "making the most" with the least effort and if you owe in taxes yes a 12K deduction could be QUTIE SIGNIFICANT.
Unfortunately, the only "nice" thing you can do for vapers generally is to list it for sale in clean, decent condition for reasonable prices. But you aren't going to get a royal flush for this stuff for no effort, sorry. Maybe 2 jacks and an ace of spades, with a bit of work.
Again, sorry. Also, will not be buying although you certainly can sell here like anywhere else.
It's just it sounds more like a quick buck scheme than "honor vaping HELP a charity scheme" if you ask me, and if that is YOUR old stuff or a relatives, MY GUESS is you know "all" about charitable giving and the benefits thereof. Hell, I do too, but I list my stuff on receipts as FAIR MARKET PRICE not what I paid, come on now.
See what you can sell em for or dump them into the bay crying "DAMN DEEMING AND MY TAXES!:
No offense and I could be wrong but calling it like I sees it.
