I'm currently looking for a car inverter to charge my laptop while i travel long distance. However, I search through all the website such as ebay and so on, there are many types of inverter, so now I begins to confuse which is the best inverter to support my laptop: My laptop is HP Pavilion dv6, the charger output is 100-240 V-2 A 50-60Hz. So could you advise me whether should buy 150W or 200W or 300W car inverter please.
The HP Pavilion dv6 has a 90W power supply so I will suggest the 200W inverter since inverters run quite hot at maximum power. Keeping it under 50% draw will keep it cooler.
One piece of advice here, have a hard surface for the laptop to set upon - sitting it on the seat next to you may block the intakes causing it to overheat.
