Npro is my 1st vaping device. It was cheap @ $20. But the refills were $15 & they do not last very long. After some testing I found that the cartos from 21st Century actually fit & they produce more vapor. I got a disposable 21st Century from Circle K for $10. You can pop the top and refill this cart or use the cap method. This is working for me right now while I save up.

that's bizarre and i had to double check it---the batteries of those two brands won't use the same charger, so i never thought about the cartridges fitting before and i'm really amazed that they do. njoy cartridges are more expenses in my locale [$20/5].if you are really careful, you can pop the top or pop the case off of the bottom to add ejuice. it doesn't make it taste awesome, but i've had success making it taste better, while i waited on my first eGo. i'd like to find a source for refillable cartos for it and pass the batteries and chargers on to another.

Good Prophets and Azsmokefree have some RN4081 stuff.
is the njoy battery a RN4081? i had looked and couldn't figure it out.

When I first started out, I also bought an Njoy from the gas station. I used a company called neusmoke.com, thy aren't on the official supplier list, but I've ever had any problems with them. They have blank cartomizers at ~$1.50 a piece. I cant vouch for the quality, as I was using a 3 piece system at the time (battery, atomizer, and cartridge).

The 21st Century cart is different. However once it is pushed down to the end, the thread screws in enough for it to stay on. I do not know if 21st Century has different styles, but the disposable ones I use work. I found that it is easier to pop the top of the Cart and drip my juice. I will post a video in a few days. For me this was a good way of trying vaping without spending a load of money online trying different devices. For now it works, my bottle of ejuice will last at least a month & I will be able to save up and do my research as to what upgrade model I will purchase next. I was a Cigar and Pipe Tobacco smoker. I have not touched either for more than 2 weeks. The vaping tastes different and I am looking for a good pipe tobacco ejuice, but I have not wanted the real thing since I started.

21 century and Njoy have a different treads. I just tried and 21 Century carto has smaller tread and doesn't fit properly in to Njoy battery.

I just tried again and it doesn't work. The connector diameter is smaller on 21 century carto than on Njoy battery. May be it's different on disposable. I have 21 century a full kit and Njoy pro (both from gas stations).

So with that adapter all that is needed now is a 510 atomizer & a drip tip or tank?

Yep. Just don't use low resistance (stay within the 2.0ohm to 3.0ohm ohm range and 2.0 is pushing it on those weak batteries) or dual coil on those little batteries. And dripping can be messy and isn't recommended with automatic batteries.

Mad vapes also sells kr808d and 510 semi-disposable kits that will last a long time for $10. the batteries are good but the prefilled carts are nasty

Here is the video. Please forgive the noobish quality and child like shenanigans, I refuse to grow up :)
I hear that a dark back ground shows vapor better, so I used one of my shirts.

Thanks for the video. I do managed to get 3 out of 6 cartos work with Njoy battery.
It's not a tread holds carto but a battery pole fits nicely in to
the carto end opening.
Njoy battery works much better than naitive 21 century one.

I edited the video. I noticed that when I vape its in stereo because I was so close to the microphone. It should be better now. I recently got some refill carts and they were dry and tasted nasty right out of the box. So I am experimenting on ways to clean them so I can use my own juice without the old tobacco lingering. I'll keep you all posted on how that goes.
