I dont have a kGo, but I do use an E-Power, which is very similar to the kGo but uses non-proprietary batteries, and the Ressurectors are the only cartos I use. The Boges are good too, but I like the Ressurectors more. The only thing I dont like about the Boges is that they only hold about 1ml of juice. The Ressurectors hold about 2ml of juice, so you can refill a lot less often. The Ressurectors are designed for 3.7V PVs, like the E-power and kGo, and they work awesome on both. Ive tried a bunch of different dual coils, but personally I think dual coils suck at lower voltages. I think the Ressurectors and the Boges both perform better than any dual coil on a kGo or E-Power. I would def try the Ressurectors bc I think youll really like them.
And if you ever want to go even longer between refills, the Smoktech 3.5ml tank is perfect for a kGo or E-Power. They are cheap and work very well, plus they come with a pre-punched DC carto and a drip tip which makes them an even better deal. There also is a larger 6ml Smoktech tank, but personally I think the bigger tanks look kinda awkward on an E-Power/kGo sized PV, and they make the PV top-heavy. The 3.5ml tank is perfect though and its about the same diameter as the battery tube, so they look nice and dont make the PV top-heavy. Thye Smoktech tanks are dual coil tanks, but you dont necessarily have to use a dual coil. Like I said before, I think dual coils suck at lower voltages so I didnt even use the DC carto that comes with the tank. Instead I use the Ressurectors in the tank and they work a LOT better. They are single coil, but since their XL cartos, they are the same size as a DC carto and they fit perfectly in the Smoktech tanks. CCV sells the tanks in a variety of colors and you can get the regular one with black endcaps or one with polished chrome endcaps. CCV also sells pre-punched Ressurectors for the Smoktech tanks and they have the metal base on them like the DC carto that comes with the tank. You dont have to use a carto that has the metal base, but they are nice bc they stop the tank from being able to slide down, and the base doesnt allow the carto to slide when you pull the drip tip off.
Heres what they look like:
The left one and the second picture are the regular 3.5ml tank, and the right one is the 3.5ml tank with polished chrome endcaps. As you can see they dont make the PV much bigger, and I like the 3.5ml tanks bc their big enough that I can fill them in the morning and be good all day, yet their still small enough that I can easily carry my E-Power in my pocket with the tank on it. If you do get the Ressurectors and like them, I would def consider getting a 3.5ml tank also.
Between the great battery life of an E-Power or kGo, and a 3.5ml tank, youll be able to vape most of the day, if not the whole day without needing a refill.
I fill my tanks in the morning and also pop a fresh battery in my E-Power, and I can easily vape all day at work completely maintanence free
