Just to let you know in the future you can usually save some money by buying everything together in their "kits" when I first got started I bought a 510Mega kit (its like the 510battery you bought, but longer, thus nit lasts longer) I paid $60 for it, since then others have mentioned to other new comers that some sites sell them for as low as $30. But the reason to buy the kit is because you get two batteries, two atomizers, somewhere between 5-10 new cartridges, and a charger.
When I outgrew (read the batteries didn't last long enough) the 510Mega I once again bought a kit, that time it was for a Joye Ego clone. Those batteries last for 8-10 hours chain vaping like I do compared to the one hour I was getting on the other one.
But to let you know what is compatible with what. It's all in the threads. You bought a 510. So all that you have to look for is something that says 510 in the name/description. The way they sell atomizers is they list them as what is compatible with what, so it will be listed as a "510 such and such ohm atomizer" and if you are thinking of ordering some more in the future, you might as well just order a kit its not to late, and you will find yourself collecting PV'S before you know it. I'm going into my third week and I currently have 4 different models. Each one having AT LEAST 2 batteries (one has 4), and the best thing is that they are ALL 510 compatible! So if one atomizer dies, I've got plenty of backups.
Just to point you in a direction to window shop too, check out the website called "liberty flights" when you go there look in the upper left hand corner, they have a button that says 20% off. Click that before you start shopping. But go ahead and click on one of their kits called a "Riva 510". They have one model selling for $29.99, for that price you get 2 of everything that is compatible with that 510 that you just ordered. The Riva 510 is a Joye Ego clone personal vaporizer, but it is actually better then the original, the battery on that one lasts for an hour longer then the Ego. The biggest difference between that and the 510 is that it is not in the same shape as a cigarette. The Joye 510 is.
I'm more of a function over form man myself. As I said it can become addictive, and expensive. I ordered TWO Joye Ego-T kits today. One for me and one for the wife. Those models are very cool. They have a tank for the juice. No more dripping for me!
And no more leaking juice either!
Good luck, welcome to the wonderful world of vaping.
I went from smoking 3-5 packs a day to straight vaping overnight. It is a miracle, and the most amazing thing is that I DON'T MISS SMOKING. I can enjoy a cup of coffee in the morning, and I don't want to smoke.
These things are amazing.
Good luck, and welcome to the forum too!
