## Description

desertcart.com: DC4.8V~6V High Voltage Transformer 50kV-800kV Boost Step-up Inverter Generator Power Module Black : Automotive

Review: Good product - I’m love making small electronic projects. This small product worked very well in a few of my experimental projects.
Review: The High Voltage Output hurts! Be careful!!! - What you should know: #1) The manufacturer is very serious about the input voltage. Less than 4.8 volts and they don't work, over 6 volts and there is a really good chance they will only work once and then be burnt out. #2) Besides the correct voltage, you also need a source that will supply a decent amount of current. How much? I don't know exactly, but I do know that the average phone charger won't cut it. I use a 18650 rechargeable battery and a a simple momentary push button switch (see video) and they work great. #3) These things put out HIGH VOLTAGE and it hurts if you zap yourself (or someone else) so don't freaking do it!!! It won't kill you, but it will get your attention and have you rubbing the spot that got zapped for a while. I use them as a training aid with my dog's. No I don't touch them with it, just the sound of it is enough to make them stop what they are doing. Anyway, be careful and have a good time.

## Questions & Answers

**Q: If lying flat on table. and looking at it from input side. which side is hv output located?**
A: The high voltage side has two same colored wires they are red wires .
The other side has a red and a green wire that's your positive in your ground.

**Q: Could have done a better job of sealing those red wires, eh?**
A: Mine were sealed fairly well but I can understand how one or two sub par units could slip through quality control.

**Q: Can it be used to make an electrostatic precipitator?**
A: I’m not sure it would supply sufficient current although you wouldn’t need much. This device will pulse positive DC in a square way resembling AC but it isn’t so if you presented a large enough ground plane you could theoretically remove particulates by charging the gas/particles dc positive and collect them on your ground dc negative plane. Similar to those “ionic” air filters. I’d go for something a tad stronger(more current)for the desired  effect 1 or 2 amps should do it

**Q: how thick is it?**
A: 15mm to 20mm or approx 5/8 if I remember correctly.

### ⭐ HV defective unit.
*by J***Z on June 21, 2025*

I bought this unit to make a bug zapper, but unfortunately it didn't work. I don't know what's wrong with it. I wouldn't spend any money on it.
