Herborizer corner

thats nice ! I have been eyeing these kind of power supplies on aliex for a while but never pulled the trigger... I'd like one in a smaller form factor (I know they exist).

Have you been able to test amps variation instead of volts ?

Hi Radwin Bodnic
The downside of the device is its size and the active cooling fan that makes noise (like a PC's).
However, it's really stable, and the main amps are 5. They clearly increase as the volts increase. I usually range between 7.70 and 9.50 volts. I never reach the maximum of 12 or 5 amps.
However, they increase slightly while vaping, but it's just a matter of cents

Lovely set up. Had a big weed guy over and introduced him to a lot of my vapes. It is the Herborizer that he was most interested in buying. (#2 was Anvil)

With this vape you can really taste the terps and the various flavors... in my experience no other vape gives me this...

Thanks for the reply.
I was eyeing miniature units that doesn't have a fan so the noise shouldn't be an issue.

Aren't you able to change the amps delivered by the unit ?
What I understand is that you're using it as a potentiometer (tension (V) variation). I'd like to know how it behaves when used as a rheostat (current (A) variation).

The resistor of the heater (just like any resistor, thank god) has a value that increase with temperature. So when you draw, you cool the resistor and the resistance value lowers. As the power supply delivers a steady voltage it has to increase the amps slightly to cover the lower resistance value. Just the time for the heater to recover the temperature lost during the draw. That's totally normal behavior and shows a good regulation.

An opposite example is the Chinese vvps that comes with the herbo. It is not steady (voltage lowers over time) because it has a fixed current (amps) and the increasing resistance (ohms) of the heating element cause it to lower the voltage to deliver the same amount of power. That's why it stop lowering after a certain time : when temperature is perfectly stabilized.
This is not an issue per se but causes longer heating times.

That's exactly how I'm using it.

that's what happens when I vape!!!

I couldn't explain it better!!!
