new dna40 tempeature protection board

[geordie_vaper]

no dry hits
no burnt wicks apparently

[geordie_vaper]

i dont no what to think of this, it could be a good idea, but dont see how you could never get a dry hit or a burnt wick,
part of me thinks they thought of somthing that hasnt been done thats not really going to improve the vape but still be a new technology, least when there out in new mods the dna20 and 30 mods will drop in price

I read an article on it about a week ago asking the question "is it outdated technology before its even released"

The vapourshark and hana are the first to get it

I wouldn't place much faith in VaporJoes tech opnion and he does like to stir things up.  He suggest it maybe cloned, they haven't successfully cloned the DNA20 or 30 yet, just made look a likes.

Just starting on the video, but expect it to perform as well as Evolv claim and preventing burning your wicks and overheating the liquid will allow a lot more vapers to get a high power vape without such a big learning curve.

i dont know how it will stop burnt wicks and dry hits, as they are caused by user error,

It has to use nickel wire (not nichrome, but the pure nickle non-res wire) to use this, it monitors the current and can tell when the coil goes over a set temp then soft limits (turns down) the power.  So when your wick gets dry it will prevent the power heating over the limit, you will get a dry hit, but not like the nasty ones you get now.  I can still use Kanthal, but the temp limit doesn't work with it.

Reverse Battery Protection
Fires down to 1 watt !!!
Fires down to 0.06 ? nickel 0.16 ? Kanthal
Soft limits: when you go beyond these levels it just limits the power and you can still vape
Even better battery protection

Having the step-down is a big thing, all the newer 50 W+ mods are missing the low power end as the previous DNAs did.

(Only 35 mins into the video)

i should of watched all the video but had to do some work,

I see temperature is the innovation with it, but dont see how that can work if the atty doesn`t have a sensor. I can see it being just the thing for all in one mods (where a sensor could be built in to the atty or for burning a few leaves slowly  the current reading would need to be incredibly sensitive. "Step Down" is really needed, so many manufacturers and suppliers claiming their mods will go below battery voltage when they wont.

My signature pic below is probably quite relevant

There will be Kanger, Aspire & Innokin heads with the nickel coils available. They will later release a 25 W version that will be cheaper for mass market mods.

What will it mean to the vaper:

• You will be able to use all the juice in your tank (steel tanks & drippers) without worrying if you are going to run dry and kill your wick.
• People that are moving up from gen 2 will get a much easier transition with the lower watts.
• People that are starting rebuilding are going to make a coil that vape quicker.
• You can keep vaping (at lower power) if you let your battery run down and forget a spare.
• It will work with coils down to 0.05 ?, but will limit the power for Kanthal at this level.
• It will protect people who can't be bothered to learn battery safety when they have a bash at sub-ohming.
• It wont self destruct if you put the battery in the wrong way round like the previous DNAs.

Evolv have always had top notch reliability and smooth power delivery, unlike the new 50 W+ chips and clones the clones. It will only be 20% more expensive than the DNA30 and a version will be made with the temperature in Celsius. No release date yet, but my guess would be around xm@55. Some will winge that it is only 40 W, but very few people vape at that level, I have read more threads from people with problems from mods now going low enough. I will try and get one when they hit the UK and make another 75 x 22 x 38 mm 18650 mod, just wont bother with the charger board this time.

It is a max temperature limit, not temperature adjustment.  You have to use pure nickel wire and it can tell by the change in current drawn that it has changed resistance due to temperature so will back off the power until you back under the temperature limit.

It will let you use low spec batteries, but the soft limiter will back off as soon as they go down to 2.75 V under load.

So it`s gonna measure the current when you hit the fire button and then monitor it looking for a pre determined rise in current which will mean the temp has risen as the coil is not getting cooled by the wicking ability due to low level of liquid. The liquid is in fact a coolant for the coil. It makes good sense.

Official release date for the DNA 40 is Tuesday October 14th (To US manufactures)

I'll have a couple of DNA 40 sharks in a heartbeat

I watched the video and the Evolv guy's main aim is always vaping safely which in my book is the number one priority to get all the regulatory bodies to leave us in peace to vape.
