i was told you had to use an rba for a mech mod is this true or can you use a tank like the protank
I can relate my own experience with that. I was using a Protank on a spinner battery when I got my first mech a Sigelei 24, and the first vape on it was a real eye opener. Wow, wall clouds happening right away. I was very pleased, but soon found out that a mech will go through Protank coils pretty quick, and I found myself rebuilding them all the time. 1.8 ohm Protank coils didn't last me very long on my mech. Okay, I'm a chain vaper, and was a 3 pack a day smoker before I started vaping, which prolly has something to do with it, but I don't think a Protank is really the way to go on a mech. At least it didn't prove practical for me.
After a period of rebuilding Protank coils and buying enough of them to have a good supply, I decided it was finally RBA time, and ordered up an AGA-T2. It's my daily vape rig now, the RBA and mech, and I'm quite happy with it. I've not used my Protank since. As always your mileage may vary.
You may want to get yourself an RSST, which is a kinda the Ford Taurus of RBA's, and a very good beginner's RBA. You can get one for less than $30 online. The AGA-T2 (the 64 Chevy Impala of RBA's) is also very good, and I think it's better looking.
