The idea behind this item is very good. It supposes to deal with an input Voltage in the range of 6 Volts to 24 Volts. Unfortunately, the received item was not working and seller has no interested on verifying the issue, so a Refund asking was necessary. As said, a very nice item, if it worked well.
