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. ## Features - This module is a finished module of transformer/booster for small scientific production - It can output high voltage arc, small size and high efficiency - The input voltage is DC4.8V-6V and will output 50kV-800kV high voltage - It can be used for high voltage experiment, teaching in high school or college - The peripheral circuit is simple, simply connect to switch and battery, and the discharge is great ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078SSC1GW | | Best Sellers Rank | #865,980 in Automotive ( See Top 100 in Automotive ) #869 in Power Inverters #5,595 in Car Audio & Video Accessories | | Brand Name | Walfront | | Current Rating | 5 Amps | | Customer Reviews | 3.9 3.9 out of 5 stars (86) | | Item Weight | 0.04 Kilograms | | Manufacturer | Walfront | | Minimum Frequency | 50 Hz | | Model | Walfront8tvfmg032k | | Mounting Type | Surface Mount | | Part Number | Walfront8tvfmg032k | | Power Source | Battery Powered, Corded Electric | | UPC | 663862652895 | ## Product Details - **Brand:** Walfront - **Current Rating:** 5 Amps - **Item Weight:** 0.04 Kilograms - **Mounting Type:** Surface Mount - **Power Source:** Battery Powered, Corded Electric ## Images ![DC4.8V~6V High Voltage Transformer 50kV-800kV Boost Step-up Inverter Generator Power Module Black - Image 1](https://m.media-amazon.com/images/I/61641ovGhnL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by L***E on July 28, 2025* I’m love making small electronic projects.
