Not an Aooci, but I have a Chigee that does the same thing and it’s been great.
I had a pair of USB sockets next to the dash to plug my phone into when on its migsel mount. The power to these was just via wires from the battery, switched via a relay and autoswitch device, to a pair of spade connectors, so easy to remove from the old device and connect the bare wire ends of the Chigee to spades and slot them together. Shrink tube protects it all from the elements and it all took about 20 mins. A 0.75-1 second press of the indicator cancel button actives the relay and powers the Chigee when the ignition is on.
