Battery life is short when used above 3.7V/ 7watts.
You're telling me. I currently have a 1300 mah vision spinner that I'm more than happy with. I was going to order another spinner but I've read a lot of comments about the spinner's button going in short order. So I thought, maybe not a second spinner and stumbled upon the emax. I love the size of the spinner and this is almost identical (a little taller). And I thought battery warning notification and VW to boot, why not?
So I've only had it a day so this review will be brief but not thrilled so far.
I use my spinner at 3.8 v and works like a champ. Get about 12-13 hours out of it, I use it a good bit throughout the day as I can vape at my desk at work. I continued using my spinner and thought I should give the emax a full charge before using. I know they ship with a partial charge but thought I'll top it up. It was charging (light red) and went green in only about a half hour. I thought cool, it came with a good charge.
I used it about an hour, maybe an hour and a half last night and went to bed. I used my spinner throughout the day today. I got home and thought I'll charge my spinner and switch to the emax. Using it about 30 minutes and now the led cycles white/red/blue upon pressing. 5 presses or 3 presses does nothing. So I assume the battery is drained but I'm thinking what the hell? I got two hours out of this and where was the low battery notification? I'm going to chalk this up to a first charge cycle (I doubt that but I hope anyway). So it's charging now.
The other negatives are the dial feels very crunchy to turn. Granted, that's better than loose, but it just doesn't feel right. The other negative is the font is light and really thin very difficult to read the current setting. I got the chrome one as my spinner is black. I was going to get black again but the emax has a shiny finish on the chrome and black (unlike the spinner that has that kind of grippy, rubberized finish that I like on their black model) So the font is very hard to read on the chrome one. Not sure about the black one. And I've read the red marker indicator on the dial wears off very easily, but obviously haven't encountered that yet.
The dial and the font aren't too big a deal, but if that first charge is any indication, then it's junk.
Oh one other negative. The threading isn't the greatest on the 510 connection. I have 3 beauty rings (one for a mini, two for regular size clearo tank). I can't get the mini beauty ring to thread no matter how many times I tried but I can get the other two. All 3 of these thread easy on the spinner.
And doing the shake test the button moves more than the spinner. I hope the short charge was just a one time thing, but I don't see this being better than the spinner. Haven't testing vw yet.
Does anyone know how it indicates the battery is low? I'd like to see the 30% warning. And will it warn you only once or on each press?
