I second or 3rd this... I have a 175 watt and a 300 watt inverter... the 300
can NOT run my laptop... it will charge it (takes a good while) But it will
NOT run and charge it at the same time..... 3 mins into running the fans
kicks in ..less than 5 mins the alarm goes off and it shuts down. The 175
watt one, with no fan would run my old laptop for hours. The New one... will
NOT run my new bigger laptop .. The power brick says ... 120 watts ... go
figure?.. my .02 worth... get a min 750watt inverter... if you're doing
anything more than charging your cell phone or small camera batterys.

not enough.
