- Button-top cells only: Tenergy says flat-top cells do not make contact.
- Runs from the 12 V adapter or a car socket, not from USB.
Affiliate link: if you buy through it, the merchant pays us a commission at no cost to you; that commission pays for the cart tests behind every code here. Price, availability and each code were checked on the merchant's own US store on the dates shown; they change, so the store's checkout is the source of truth. Full disclosure.
