inverter review Victron 350 watt pure sine wave

Hi all,

I finally got the Victron 350 watt pure sine wave inverter wired up with a cigarette lighter plug.

It is intended for use with a laptop and heating pad.

Demand with the old 400 watt MSW Motor Master (from Canadian tire) was about 5 amps running the laptop. The MSW got quite warm running just the laptop, and the power supply as well as the laptop got extra warm. The fan would run when booting the computer. When I would add the heating pad the cooling fan ran constantly.

On the Victron demand is down to 3.78 amps, the power supply is much cooler as is the laptop. The case on the Victron doesn't warm up at all. Adding the heating pad did not cause the cooling fan to come on. I should have made this jump a long time ago.

Cost for the Victron was a scant $80 USD.

It is considerably heavier than the MSW unit, and about three times the physical size. I've not looked inside, but I think there may be a nice big transformer in the Victron.

Conclusion:

Highly Recommended!

  • The Victron weighs 7 lbs.

    Time2roll, It would run the absorption fridge (325 watts) IF it were not connected to a 15 amp fused circuit.

    BFL13 computers are run by a switched power supply. Mine clearly doesn't "like" MSW as well as it likes PSW.
  • Yeah the Harbor Fright Salvage 600 watt MSW perverter weighs 1.1 pounds cause of the "transformer with all that copper". High Freak does not rely on transformers only piddly inductors. Chew & Spit technology recycle parts.

    It is all resistive loads, so how do you explain the difference other than by size of transformer?


    the laptop is not a resistive load
  • Fridge on a DC 8a cig plug? If it has a second set of Dc cables with clamps, you could do the time2roll trick behind the Dc fuse panel, but the continuous watts must be around 300. Fridge needs 600 -1000w?
