Wattage dropping

[Aeden]

Hello,
I have a big issue with my electronic cigarette. I bought uwell nunchaku 2 a half year ago. But last 2 months i have problems with vaping. Whenever i press the fire button, the wattage falls down to 20-27W. It doesnt matter how many watts i have set. I have set 60W and it dropped to 25 or i have set 40W, it falls down to 25W. It feels like a weak pod system. I have tried cleaning the connections between the atomizer and the body of cigarette, but no result. Does anyone have an idea how to fix this problem before the complaint? Thank you very much!

Hi and welcome,
It sounds like a battery issue.
The uwell nunchaku 2 uses a removable 18650 or 20700 or 21700 battery.

What is the brand and model of the battery you are using and what is it's age?

Do you have an external battery charger?

Where are you located?

Cheers
I

I use 18650, 3000mAh, 35A by EFEST. I use the original charger. Its 1 year old battery, but i have an another one which is newer. My friend has got nunchaku 1 and we tried to exchange our atomizers and my worked very well on his body, but his atomizer did the same thing as mine on my cigarette body.
I an from the Czech Republic.

It seems a new battery is in your future.

I use NKON | Home page
In general, select batteries from trusted manufacturers and only buy from trusted vendors.
You may want to consider something like the Samsung 30T or 40T models.

Welcome to Ecf @Aeden

Efest batteries are notorious for being rewrapped seconds from other manufacturers with inflated specifications. I had a couple that crapped out way before their time.

Clean your battery cap threads as well as the threads on the mod. See if that helps a little.

I cleaned it all And i have tried three other batteries but it didnt work
And the Efest battery was recommended by the seller, so i thought it is the best choice. At least i will pay an attention during next shopping!

Well, other than trying the "factory setting" reset function on the mod (which I doubt will do anything, but it's worth a shot), your next troubleshooting step is to use a different battery. Try your friend's battery if you can. If a known good battery doesn't fix the problem, you know the PCB in the mod is toast.

i tried my friends batteries and it didnt help
And excuse me that i forgot to mention that i use 0,4ohm coils. But it is interesting that my old coil works normally, but its burned and the others (even new) do the same problem. So with one coil it works.

And do u think that the company will accept my complaint? i dont think its my fault

The Uwell Nunchaku 2 has some type of motion sensor gimick that can be used to adjust wattage .
If the readout on the screen is dropping down from a set wattage with one coil and not another then maybe this "feature" is activated/malfunctioning.

If I were you I'd try reading the manual or emailing Uwell.
Good luck

What is the resistance of the old coil that works?

Its 0.14 ohms.

All you can do is try. No one can answer that question.
