Umates PowerMate is a new revolutionary converter for operating 220V devices in your car or your boat without the need for special 12V chargers! Umates Power Mate supplies your car with 220V from the 12V socket. This means you can charge your laptop or other 220V product without the need for a special charger for each. You no longer need to invest in several special adapters - your 220V cable fits into the PowerMate. Outputs 220V Umates PowerMate converts 12V to 220V, ensuring less wear and tear than when charging devices at 12V. And charging at 220V is faster than charging at 12V. The charger that knows when to stop. With the car engine switched off, the converter stops drawing power when the car battery level has reached 10.5V, which is the power your car needs to start. Use it in the boat. The converter also enables you to use your laptop or perhaps a small TV in your boat.
