Those minis pack a nice hit! I have one left......have had several.
However, compared to regular joyetech ego twist in 1000mah, just didn't get the life from them. I mean lifetime, not just battery life.
I've had several go bad....maybe they can't pack good electroinics into such a small thing........I can tell you that all the 650 and 1000s I have still going.......but have blown through several minis adn they just didn't last. Died on charger, etc.
It would stand to reason that the lower the capacity of the battery, the sooner the battery will die, and need to be replaced. This is simply because if a battery is half the capacity of another battery, you are going to have to recharge it twice as often, which doubles the wear and tear on the electronics.
If a 350mAh battery and a 650mAh battery can both be recharged 300 times before they die, the 650Mah one will last a lot longer, because you wont be charging it as frequently. I don't really think there is an issue with the electronics in the minis, it's just that you are charging them so much more they wear out sooner.
The minis are awesome though. I picked up a pair of Smoktech 350s when they first came out and they are still going strong today. I have a chopped down Smoktech DCT with a shorty drip tip on one of the minis and it's such a compact and useful package.
I'm Not new to Vaping, but New to the Forum! I just wanted to share with everyone that the Ego Mini 450 Mah is totally awesome..
I've been steady vaping with Joy 510's over the past 2 years... Yes I knew about the ego, but I was always turned off by it's size. The Mini is about half the size.. Throat hit is very nice! I love this little device so much I went back and ordered an EGO Twist Unit. I'm currently using 2.0 Carto's from BOGE. Nice clouds of Vapor..
Coolest Part about this device is it's size.. Not even 2 inches long, literally about the length as my standard Cartomiser..
The Smoktechs are unregulated, and if yours is also unregulated it will likely be putting out around 4.2volts fresh off the charger and then go down until about 3.2v when the internal protection will kick in and stop you from running it down anymore. That's probably why you are experiencing better performance from the eGo mini than the 510 you were using. If this is the first time you've experienced a vape at a fresh 4.2v, you'll be amazed if you get a Twist or a Spinner, although they would be larger so you may not like them.
Glad you found something you love, I hope they last you awhile!
