Here are some demos:
VoltBot is outputting 36V with the help of a cheap adapter.
Outputting 16.5V to power a Macbook.
Outputting -12V for application of operational amplifier.
Outputting 3.3V8A would suit to most processors’ power-rails.
After you skimmed the demos, here comes the details. This kit consists of three USB gadgets.
The Voltage Lifter works in this way:
The negative converter could convert 5V into -5V or 12V into -12V. The current limit varies from the voltage difference of the output. For example, it is 2A for +5/-5V conversion, but 1A for +12/-12V conversion.
The low voltage converter will cover the low voltage range where VoltBot cannot reach, and providing the strong current capacity to power a processor power-rail, or rate a shorted board under thermal imaging.
It is opening for orders now, you could order it on Indiegogo.
