Did you by chance get the Ego One Mega tank? Some of us got them with our purchase of an Ego or eVic as a kit.
As RBA tanks go, it’s not high on my list of ones to use. The stock coils, whether kanthal, Nickel or Titanium, are just not there for me. If someone is moving up from a clearomizer like the Kanger Aerotank or maybe a carto of some kind then yes, it’s a good boost up.
What many people don’t realize is this is actually one that can be rebuilt. Joyetech calls it the CLR Head. It’s easy to build and is a vast improvement over the stock coils. I use mine just because it has the matching paint job as the eVic Vt - which looks so damn cool with that automotive finish.
This is what the RBA looks like when you get it. It comes with a kanthal build preinstalled so you can use it right away. Just wet up the wick, install and vape. Or, if you want to use a different wire like I did, pull that stock coil out and rebuild your way.
Unscrew the top, pull the pin and grommet from the bottom and then remove the coil. So from left to right that is pin, grommet, body and cap (or that’s what I’m calling them).
Next just wind your coil. If you notice, the body has a slot on the top. Its easiest to keep your screwdriver, drill bit or whatever you wound the coil on in place when you insert the coil. These slots can only accommodate about 2.5 mm bit so if you build bigger, like 3mm then just pull your coil off that bit and insert one small enough to go down in the slots. Below is what I did. Built 3mm titanium then once I spaced the windings I moved to a 2.5 mm coil jig bit. Slide that all the way down the slot then rescrew in the cap to hold in place.
Next insert the grommet with one lead going through the grommet and one outside of it. Insert the pin. Then cut the leads as close as possible so as to avoid any shorts.
Once that is done, remove the cap and insert your wick. I find it easier at this point to reinstall into the base. If you have it on your device you can also check resistance at this time.
Next, simply trim the wick back till there’s about 2mm worth still poking out. Wet with juice, reinstall the cap, and as do a test fire. As long as you aren’t shorted out or anything, fill that tank back up and vape one.
Now don’t get me wrong. This still doesn’t produce big clouds. You’re probably not going to impress your neighbors or send smoke signals to your friend down the street. But as mediocre RBA tanks go, this isn’t bad at all and the flavor is quite good.
