Review on ⚡️ DEVMO 5PCS Boost Step-up Power Module: 3v-6v to 400kV High-Voltage Generator by Bryan Cavalcante
Learned the hard way that they work
These things pack a punch -2 stars for false advertising - they can never produce 400kW or even close. I would rate them at 20kV max, maybe a bit more if you stress them too much. It definitely felt like 20kV when I accidentally touched it. Not bad overall, but be aware that you won't really get close to 400kV, for that you'll need a much larger unit to accommodate the voltage multiplier.
- handy thing
- very expensive
