Topbox Nano, jumping voltage problem

[thijs]

Hello,

I have nearly brand new topbox Nano with a 0.5 ohm coil in it

the problem is when I hit the fire button the voltage changes

it are big changes; i vape at 20watts and normally its around 3.8 volts
but about half of the times the voltages get up to 4.3 volts

every hit is different like; 3.8 then 4 and sometimes even 4.5 volts

do you guys know what this problem might be?

greetings Thijs

Are you using a temp control coil, for example one out of stainless steel? The volts would then jump to maintain the watts as the coil resistance changes with the temperature.

thanks for reply

no im not using a temp controled coil, it is set on 20 watts on a normal kanger subohm coil.

i think i has nothing to do with the temperature because when its cold it sometimes also jumps to 4.2 volts
and normally it has to be around 3.7 volts i think

its a big difference and i can taste the difference

Have you Double Checked to make sure the Coil Screws are Tight?

 

[thijs]

Yes i cleaned it and checked for loose screws, the coil is almost New so i didnt replace that.
Its a facorty Made coil

It's weird though as at 20w on a .5Ω coil you should be at 3.16v. At 4.2v you'd be getting 35w. I'm not familiar with the Topbox but could it be that it's the battery voltage you're seeing?

Its indeed very weird,
The topbox says my coil is 0.7 Ohm no problem but the jumping Voltage is very weird sometimes even at 5volts! I really hope its a bad coil what is causing All this trouble, if not i made a bad choice buying this from fasttech

 

[KenD]

Try another coil. Fasttech are generally very good with returns. Just open a ticket and make sure you get an RMA number before you send the mod back.

yes i will do that, tomorrow comes my new juice and coils, if that not works i dont know
anything more i can do then sending it back

Those mods are garbage! You get what you pay for. Trust me. I have mods that can't even reach 10 Watts anymore. Its like sucking into a coffee straw! SMok products are garbage too.

 

[thijs]

All keep you updated, i like my toptank nano and dont think its garbage but we will see....

 

[thijs]

So i tried the New coil Without succes, the Voltage Just Keep jumping around with like +- 1volt!

I read that it might Be because of the tanks insulator pin, i cleaned that still Without succes.

Has anybody an idea what IT might Be and what i can try??

 

[thijs]

after a few more cleanings it suddenly works great again.

what the problem is/was i dont know

im still open for suggestions

If you Cleaned the 510 Connector, it could be that the Center Pin got Smushed Down and wasn't making a Good Contact with the Atomizer. And that when you Cleaned it, the Jostling caused it to De-Smush itself?

Or it could be that the Vaping Gods smiled down on you for some Nice Thing you did for a Vaper once?

I dunno?

 

[thijs]

yes i think also it has someting to do with the subtank, the coil or center pin in it

it's now most of the times good but i still dont trust it all the way

and the vaping gods just dont know if they like me, maybe because everbody i know
just smokes cigarettes haha
