Question about Vector VEC 024 400-Watt Power Inverter (VEC 024) 400-Watt Power Supply
Power inverters can do this if they are internally shorted or they are being over loaded. If you are just using it to charge a phone or a computer it should not be over loaded. Now if you are charging a computer and running a small cooler at the same time, that may be real close to max which may blow a fuse. Have you tried hooking it straight to the battery to see if it will run what ever you are running. It has it's own fuse so if it has an internal short it will blow that fuse. It if works hooked to the battery and is just blowing the cig lighter or acc. fuse it can be a weak socket. If the socket is hot it may have a loose wire on the back side causing low voltage which can blow a fuse. So hook it to the battery direct, if it works ok there, reconnect it to your acc port and if it is getting hot it may be the weak socket. If it will not run hooked to the battery, it has an internal short and it would be better to buy new than try and fix. Sorry.

The reason its probably blowing the car fuses is because its drawing too much current which blows the fuse which could be a component shorting inside the inverter. This is usually down to either blown Power Transistors , Capacitors or Diodes. Has the same problem with a car amp, kept blowing the fuses and was found out that all of the power mosfet transistors had shorted out and burnt as well as the main diode.
Hope this helps.
