To calculate the output power of the unit, use the specifications listed under "output". Yes, you can use a power supply with a higher wattage, however you need to pay attention that the voltage doesn't deviate more than one volt from the voltage of the original power supply. It also doesn't work the other way around; your new power supply needs to have at least the same wattage as the old one. To use your laptop in a vehicle you need a car-adapter, which converts the 12 Volt your car provides to 19 Volt most Laptops need.
If there is no car-adapter, that is compatible to your notebook, you can use an inverter which generates mains power from the power, supplied by the car. You can then plug your normal power supply into it. Not necessarily, try taking your battery out if possible and starting the computer while connected to the charger in question.
If it starts, the power supply is working but something in the Notebook is broken. There are also multiple indicator lights, on the laptop, whether it is being charged, also this can be seen in most operating systems. You can also use the indicator light found on some chargers to diagnose an issue with a cable. The most amount of heat is produced when working on the Notebook and charging the battery at the same time.
As long as you can touch your charger without getting burnt, its temperature is probably within specification. However, it is most important, that the heat can be dissipated, therefor you should never put your power supply under a blanket or in a closed drawer.
The CE-mark confirms, that the power supply is compliant with all EU regulations. If the CCC-certificate is present, the power supply may be im- or exported to and from China. The Singapur Safety-Mark is issued by the technical inspection agency of singapur. The technical inspection agency inspects for compliance with the product safety law, integrates many other product specific checks and asserts whether the manual is correct and complete. The UL-certification mark for sustainable products indicates, that a product has been tested by the UL Environment Inc.
The UL Listed-mark indicates, that a representative unit has been tested by the UL and meets their safety criteria. These criteria are largely based on the safety standards published by the UL. A Qualified Vendor List QVL is a list supplied by a system or motherboard manufacturer of parts tested and confirmed by that manufacturer to work in their hardware.
