How to Disassemble and Refill the NJOY Pre-Filled Tank

A while ago I did a review of the NJOY Convenient System, which is basically NJOY’s vape pen kit and it’s one of my most popular videos ever. I think it’s because it’s a beginner setup that’s extremely accessible since you can find it a Walgreens and 7-Eleven.

In my original review, I mentioned that other people online have said that they’ve been able to take the pre-filled cartridge apart and refill it. I’ve tried many times to get it apart with no luck, but this weekend, I was determined to do it, even if I had to break one to see how it was put together. And I’m happy to say that I figured it out and have now done it on three tanks.

5 Ways to Make E-Juice Thinner


I came across a really interesting thread online about thinning out e-juice. This person has a friend that has an allergic reaction to PG, so his friend asked him to create a PG-free e-juice.

Here’s what I found.

Vape Battery Safety Guide for 2017

There has been a lot of talk of battery safety lately because there have been a lot of stories in the news about vape explosions. While the media claims that these explosions are caused by electronic cigarettes, the culprits are actually caused by improper use of the batteries that people are using in their devices.

Look at any e-cig explosion in the news and you’ll see that in every case, they are happening to people using mechanical mods or people carrying loose spare batteries in their pockets. I can’t think of one example of one of these disasters happening to anyone using a regulated device or someone who carries batteries in a protective case.

So with all of these stories in the media right now, it makes sense that would put out a guide to battery safety.

I’ll run through some of the tips that they’ve compiled along with my own thoughts and insight for each tip.

Building My First Twisted Coil

I haven’t really had much of an interest in building advanced coils because they seem so time-consuming, but I received a comment yesterday on a thread I started a while ago on ECF.
