How does this work? VV/VW

[highweigh]

Hello all! New to the forums and somewhat new to vaping.

My question is in regards to the VV/VW devices such as the Hana dna 30 or other clones.

For example I am using a Sony VTC4 30a 18650 battery, with a peak of 4.2 volts. If I'm using a 1.5 ohm coil, at 20 watts, it should require about 5.5 volts to reach 20 watts at this resistance.

I'm having a hard time understanding how these devices put out more volts than the peak voltage of the battery. Can anyone elaborate? Thanks!!

The electronics (chip) in the device boost the voltage. It can boost the battery voltage but not buck it down

There's lots of different ways to achieve it... You can use a voltage doubler for example, which then would bump the 4.2 to 8.4, then regulate it down to the desired voltage... You can use a DC to DC converter... An iron core transformer... Or you can bump it up (i.e. doubler) then use pulse wave modulation to "simulate" the voltage you want applied, etc...

But the important part is this... Voltage and Current are exchangeable... You can take 5v at 10amps and "transform" it to 10v at 5amps... or take 5v at 10amps and "transform" it to 2.5v at 20amps, etc....

A boost regulator is used to increase battery voltage.
