Got the original mini in December. Just got the Mini 2 today. Thx for the PWM v. DC-DC info. The "instructions" that came with the Mini 2 were the same as my originalThe fire button seems "softer" on the 2 than on the original. I had a little trouble with the battery chamber - it seemed narrower than on my original. Battery slides right in on the original, but seemed like it was catching on something on the 2.
Haven't cranked it up yet, but very pleased with it. Vapenw now has them for $59.99.
Your Welcome.
With the battery out, Check the (2) pins that hole the Cattery cap Ring in the mod(threaded ring on bottom) One is probably a bit long and rubbing the battery as it is pushed in. One of mine is like that. A little filing would correct.(open to service)
