Absolutely NOT! You dont say what screen size but guessing 15 inch ?
This machine has an 85W mains charger. I have found that it need an invertor charger well over the rated amount for continuous use . It will get hot in use, never leave it attached without the engine running or attended. Have an on board fire extinguisher is a good idea.
Try this from Sterling, not necessarily from RS, who make proper electronics and know how to rate components for power delivery. Cheaper non branded units are a fire risk.
