    You know, I'm not sure. I'll put mine on and see. One way sure is to have all four bars 'lit' when you're done.

    Here's a useful test. From cold time how long to say 375 degrees. Then do it again (be sure it's cold again), this time with the charger plugged in. If the charger is working the second time will be a fair bit shorter. Maybe 2/3 or 3/4 the time?

    Edit: That was easier than I thought, it was fully charged. I was going to take it out the other day and changed my mind and used another vape instead. So when charging the bars 'ripple' left to right. Once charged ripple stops with all four lit.

    Ok then my unit has never been fully charged. It always shows the ripple. I will do the heat up test later

    This is making more sense now. It's still possible the charger is low in output, something that's probably not tested before shipment, it sounds like a failure in one of the three square batteries stacked in the lower corner of DV or the charge control board opposite them. Those problems should have been checked for in assembly/test of the unit. The heat up time test may help sort that part out.

    One sure way to solve it is to give the lot back, of course.

    Have you considered the possibility that the vape gods are trying to send you a message about owning a DV?

    Good luck in any event. If you choose to cross the vape gods, I don't know you......

    Ape please just call and return it. If it ripples and you tried charging for so long it is broke. I don't get why you are trying to fix a new vape that should work out of the box beside from having to do burn-ins.

    I have to agree - if you bought a Vape that doesn't work at no fault of your own then why hassle yourself? Karma seems like a really good company and supports their products through and through.

    He basically said why he's reluctant back in his initial post(s): Karma says "not for illegal substances", and he ignored that.

    Ape, ISO it real good, pack it up, call Karma (DaVinci) and send it back... by this time next week, you'll have a brandy-new one.

    There is no issue if you clean it. I have forgotten and sent one recently back without cleaning...not a big deal. Just FYI it wasn't a DV.

    I want nothing other than to return it. I got it at VaporNation and the customer service is horrible. They take days to reply by email. I'm just looking for another number for DaVinci. I don't want to call and get somebody who A) doesn't know what thier talking about and B) can't help with any problems I have. Who can I call or email to talk strictly about returns? Or do I just need to call the same number? II wanted to return it the moment I realized it was defective. I emailed VaporNation last Friday about an hour after I received it, during business hours, and have still yet to receive a return email. Like I said earlier, I'm sick of dealing with this Bullshit customer service.

    This is what I would do:
    Call not email vapenation if you get nowhere call davinci and ask for returns for a defective device. If you get a dumbass then ask for someone else or a stupidvisor.

    I contacted DaVinci and they said they would replace it, but I had to register first( I had forgotten to do so) then they would email me or call me. I registered and still no email. I'll call back tomorrow. I'm glad I have back ups because my DaVinci will not even power on anymore. If I flip the switch, nothing happens. It took 4 days for it to give out hahaha.
    By the way-
    Heat up time from cold to 190 C no charger: 1:38.6

    With the charger: :50.6

    So there was a noticeable difference in heat up time.
    I couldnt use Fahrenheit because of the defect but 190 C is 374 F.
    If nothing else, I figure I might learn to tell the temp in Celsius

    Hey Ape,
    When I got an RMA for mine I did it over e-mail. I talked with Jessica and she was super cool. I highly recommend you contact them through e-mail. She contacted me right away, less than an hour after my e-mail to her. I had my new DV 3 days after talking with her, before they even got my old one.
    Also, I am fairly sure the DV is done charging when all 4 bars show statically without blinking off (as OF suggest.) This is about ~3 hours of charging from a very very low charge. I believe, from what I know about these batteries, the initial charge is very important. So with the new unit make sure you put it on the charger for at least 3 hours before using it.

    I agree with this. In theory this should have been done as part of testing the on board charge controller (remember there are 3 batteries in there to charge....), but IMO doing this is a good plan 'just in case'. It's one of those 'chicken soup moments', you know "can't hurt, might help"?

    For better or worst you own the batteries once you start using it, IMO you don't want to start out with a weak or lame one....hopefully it'll be a long haul for you both.

    Thank you, I've been wanting to email them since Friday. I just never think to use those reports anymore because when I used to I would never get a reply

    EDIT: By the way, I emailed VaporNation about THEM sending me a defective unit last Friday and I still don't have a reply. I would not recommend them at all. That is horrible customer service! I emailed randy once at PuffItUp and seriously got an email back within 2 minutes.

    Hello! I have been reading this thread for a few days now and wished to ask a question:

    Lithium ion batteries get stressed and lose capacity when introduced to prolonged heat. Due to the fact that this portable has overheating issues, would it not render the battery useless after awhile?

    Obviously many of you have owned the DV for awhile without this dilemma (I am assuming). I am just curious as to how Karma overcame this?

    Just ordered a DV and Solo and cannot WAIT to try them out. Current owner of the Extreme Q but have never owned a portable before.

    Thank you to everyone for the great information on this model.

    First off, howdy, welcome to the fun. If you're considering buying this guy, I think it has a lot to offer. There are also some other excellent portable vapes around, you might want to spend a bit of time exploring them?

    Anyway, while high temperature can be an issue, however I'm not aware of any overheating issues that might impact this. Perhaps you could enlighten me?

    It gets hot for sure, but 'too hot to hold comfortably' and 'killing my battery' is a lot of degrees. A lot. High temperature versions of this kind of battery do fine at temperatures you can't hold on a bet. More over they are stacked up in the coolest corner. The electronics, in a hotter area, will take a dive before the battery is threatened. The LCD display before that. We're not really there even.

    I expect mine will go several years (many hundred cycles) before I start noticing battery life going down. From then on it's a matter of how much I'll put up with. Much like a several year old laptop (which uses a similar batter as a rule).

    Welcome to the forum - I have to agree with OF, if you take care of your toys, keep em' clean and charged as needed you should not have any issues. You mention you just ordered a solo and a DV - bravo on both as you just bought two solid pieces of equipment. I for one have both and although I use my solo more both serve a very different purpose. The DV is my on the go vape for sure - easily concealed, doesn't look like a medicating device, and quite candidly - it has a built in storage compartment - it doesn't get easier than that! Again, welcome to FC - keep us posted when you receive either - were all eager to hear your opinion. :peace:

    Howdy, OF

    Thank you very much for the answer.

    I actually ordered both the DV and Solo yesterday. Unfortunately, I work high up in the Canadian Arctic and they will take two weeks to arrive. *sigh*

    Looking to use the Solo at home/work trips/friend's house/etc. and will use my DV for outdoors (Mexico vacation, not the Arctic!).

    Again, I appreciate you taking the time.

    Unfortunately, I have yet to recieve a reply. My fingers are crossed that I get it today. I atleast want to have my new unit by Friday, but it doesn't seem like they are trying to replace it at all. I'll have to say, not too impressed with the customer service. I've e mailed and called VaporNation; no reply. I have called Davinci twice, left a report, then found an email address and emailed them and have still not got a reply. They are the ones that put out a defective unit, idk why I'm having to go through all of this trouble.
