Its only slim ecigs , like the v2 and elite 808, that can only use standard resistance cartos. Bigger battery PVs, like the kGo, can use LR or SR cartos.
If you get Boges, I would get the LR 2.0ohm cartos. The 2.0ohm ones will provide a warmer vape and more TH compared to the 3.0ohm ones. The Boges do work well, but their only downside is that they only hold about 1ml of
juice.
Another option is to get some Smoktech 1.7ohm XL cartos (also called the Ressurector by CCV).
I recommend getting the Ressurector cartos bc I think youll really like them. I use an E-Power, which is similar to the kGo and is 3.7V like the kGo, and the Ressurector cartos are the only cartos I use. They are designed for 3.7V PVs, like the E-Power and kGo, and they work awesome on both. The Ressurectors are 1.7ohm so they will give a nice warm vape with really nice TH, and they produce a LOT of vapor. They are single coil, but many people feel they produce vapor similar to a dual coil. They also hold about 2ml of
juice, which is about twice as much as the Boges, so they last a pretty long time between refills.
Hoosier sells them and calls them the SMoktech 1.7ohm XL cartos, or you can get them from CCV and they call them the Ressurectors, but their the same cartos regardless of what the name is.
I buy all of mine from CCV bc they have free shipping which is nice when you just want cartos, and their prices are good. Also if you get a 15-pack you get a free drip tip. Dont forget to put in "ecf5off" to get 5% off the order. With the discount you can get 15 Ressurectors for under $21 shipped.
And you could always use a tank later to make them last even longer. The Smoktech 3.5ml tank is perfect for the E-Power and kGo bc it works great and isnt overly big. I use the 3.5ml tanks on my E-Power and love it. They are dual coil tanks, but I think dual coil cartos suck at lower voltages, so I use the Ressurectors in the tank instead and their a LOT better.
CCV and Hoosier both sell pre-punched Ressurectors too for the Smoktech tanks and they have the metal base on them like the carto that comes with the tank
