Review on Hardwire Supply Wilson DataPro Boosters by Bryan Gilliam

So I have a WeBoost Signal 4G car amplifier on my desk. It originally comes with a 120V outlet, part number 859948, according to the Signal 4G user guide. The power connector on the Signal 4G is a 5mm jack, so a 5mm plug is required for power. The 859989 power supply IS LISTED AS AN ACCESSORY IN THE SIGNAL 4G USER MANUAL, however this power supply has a USB Type B connector. This adapter is not compatible with Signal 4G and nowhere in the documentation on the WeBoost website is it mentioned the types of connectors this adapter has. I'll be sending it back and looking for other options to power this amp so I don't have to hook up a 120v inverter in my work truck as well.
