OOPS!! My apologies, it came from Amazon not eBay.

They now cost $13.06 plus $3.99 shipping, but that could be due to our dollar.

Original specs:

DC-DC 8-32V to 45V-390V Step Up Boost Converter Module ZVS High Voltage Capacitor Charge Board
Descriptions:

High Voltage Boost Module
Module Properties: Non-isolated step-up module
Input Voltage: 8~32V input(the default is 10~32V input.)
Input Current: 5A (Max)
Quiescent current: 15mA (12V liter 50V, the output voltage, the higher the current will increase too quiet)
Output Voltage: +45~390V continuously adjustable (default output ±50V)
Output Current: 0.2A Max(with input, output pressure related, the higher the output voltage, output current is smaller)
Output Power: 40W (Peak 70W)
Working Temperature: -40 ~ + 85 degrees (ambient temperature is too high, please enhance heat dissipation)
Operating frequency: 75 kHz
Conversion efficiency: up to 88% (efficiency and input and output voltage, current, pressure-related)
Short circuit protection: Yes.
Over current protection: Yes. (Input current exceeds 4.5A, reducing the output voltage)
Over voltage protection: Yes. (Output voltage exceeds 410V, lowering the output voltage)
Input reverse polarity protection: Yes (non-self-healing, reverse burning fuse, try not reversed.)
Installation: Four 3 mm screws
Wiring: free welding output terminals
Size(L*W*H):60 x 50 x 20 mm

Applications:

1.Pressure test power.
2.Hunting,eradication of mice.
3.Capacitor charging, electromagnetic guns, power supply.
4.The power supply for your electronic device, according to your system can set the output voltage value.


Yes I read a little Chinglish.

There is no city/state/country of origin supplied. They came fairly promptly though.
