Seeking old school pcb protected mod

What's an old school e-power unit?

What's wrong with them? Are the buttons/switches starting to fail?

Maybe a mech with a kick in it will suit you just fine; the kick is the pcb part


The poldiac is one of the few top fired mechs:

Do you want the power to be regulated to stay the same as the battery discharges? Do you have cost and quality preferences?

On another note, variable voltage and variable wattage are so prevalent these days, you're really limiting yourselves by not considering them. If you set one at say 3.8 volts, or say 8 watts and leave it there all the time it becomes irrelevant. Just a thought

 

Provape makes a fixed power regulated mod

 

I used both the 14 and 18 E-Powers and loved them, still have them. I think the closest you'll come nowadays is the Joye Ego-T Mod.
