Review on 🔌 OOWOLF Cigarette Lighter Adapter Quick Charge 3.0: 180W 12V/24V 3-Socket Power Splitter with 4 USB Ports - Ideal for GPS, Dash Cam, Sat Nav, Phone, Tablet, and More! by Wendell Chapman

This little power supply is well designed and appears to be well made. 180W is the maximum you can get from a car's cigarette lighter socket, and this power adapter gives you the flexibility to use that power across a wide range of devices. 4 USB ports are always a useful addition. Even if your car has them as standard, they are in high demand as most modern devices are USB powered. For your 12V devices, you have 3 100W cigarette lighter sockets that can be switched on and off independently. The entire unit can also be turned on and off, which is a nice feature. There is a handy voltmeter that shows the voltage your car is supplying to the device. This can be useful for troubleshooting and should be closely monitored to ensure your car's 12v system is in the correct range (should be 13-14v when the car is running). not very long, it was enough for me to attach the power supply to the dashboard (using 3M Velcro), so just perfect for me. I'm considering getting another one for the back. Automobile.
