This adapter is for use if you are using an 510 e-cigarette battery. With this adapter you can use our V3 (KR808D-1) cartomizers on your 510 device.
Popular 510 devices include the electronic cigarette brands like E-lites and Skycig. These devices run at a lower voltage than our batteries, but you will still get good results using our carts. Our carts are easily refillable and are more cost effective solution.
It's important to note that this adapter will not connect your 510 connection carts to our KR-808 batteries, it only works the other way around.
