Get a small 150w inverter for charging laptop and phone, it's cheap, MSW type is fine.
No, no! Don't use a MSW inverter for your electronic devices!
I killed my laptop that way, after charging fine the first few times. Plus, the MSW did something to the laptop charger, so when I used the same charger on a different laptop, on 120v shore power, it killed that second laptop too.
Just get 12 volt chargers for your electronics on eBay. About $10 for the laptop and $1 for two phones. Or get a small PSW, if you want to run the TV and stuff.
