The COMPASS 12/230 V 300 W voltage converter is a great companion for trips and for cars without a 230 V socket. Portable, powerful and reliable, the small details in the minuses do not detract from the overall comfort of use. Ideal for powering small electronics and charging devices on the go.
Easy connection to car battery or car charger - ideal for travel and trips
300 W continuous power and 600 W peak power - allows you to power smaller appliances without problems.
Output voltage 230 V with modified sinusoid, suitable for common electronics.
Built-in active fan and USB connector for charging other devices.
Compact and lightweight - easy to carry even in a smaller car (0.61 kg).
Modified sine wave may not be suitable for very sensitive appliances, e.g. some laptops or audio devices.
Only one 230 V socket - a splitter is needed for more devices.

I don' t know if the converter “misunderstands“ the laptop power supply, but when I connected the power source - even without load, the converter went out.
I don't know
after connecting the power source to the laptop, it malfunctioned, so I' m returning it
does not have a standard CS socket

It works
Charges laptop and all mobile phones at once without problems (via three)
It is stupidly held in it by a 230V plug
The fan hums like crazy, like a hair dryer.
After two years (= week of use) the fan has left. I'm gonna file a claim.
