I need to buy an inverter that goes straight from my ciggy lighter that can power a laptop. What kinda power do I need? This isn't going to be used often (trip down to London from Newcastle and DVD's on the lappy should keep my son happy for a bit).
Bay of E have some smashing 75w inverters for pennies:
This one too...
Would either power a laptop as stated in the ad, dont want to melt my laptop of kill my battery!!!
cheers in advance
