This is an after Kickstarter sale of the popular USB912™ adapter.
USB912™ is a small DC to DC converter that converts 5V from USB port to 9V or 12V selectable by a switch, one end plugs into a USB port, the other end has a standard 5.5/2.1mm DC jack. It's meant to be used with a 2A USB battery bank, but it can be also used with a PC USB port provided you don't need to draw much power since those are limited to only 500mA.
It's great to power various 12V car gadgets, LED strips, PC fans, etc ... With a battery bank it can be used as a portable isolated power supply. (It doesn't provide isolation by itself though, battery bank not included)
DC to DC converter is based on a low EMI controller utilizing dithering to spread the operating frequency spectrum. LC filter on output is used to achieve almost no output ripple and small ripple noise even when drawing higher current. The adapter has short circuit protection and overheating protection. The adapter will not draw more than 1.2A from a USB port. Maximum output current capability depends on the selected output voltage and max current rating of a USB port.
In addition to a standard 9V/12V edition, other output voltages are available as well. You can also request a custom set of two voltages from 5V to 30V if the one you are looking for is not in the list. (Contact me before ordering for details)
Optional extras include set of eight barrel adapters and a 9V battery adapter. With the 9V battery adapter you can use USB912 to power a device that requires a 9V battery. Note: Do NOT connect a 9V battery to it, although it looks tempting. This will damage the adapter.
Specifications are listed in the table bellow. Exact output voltage is 9.0V and 12.3V ±2%
