110V pure or modified sine wave?

[QCRanger48]

Is the 110v outlet in the rear seat a pure sine wave?

That’s a loaded question, being inverted it definitely will have distortions. Why do you ask?

I guess the simple answer is no. Okay what type of distortion and harmonic content is measured under different load conditions.. I think that’s your question. I don’t know the answer because I’ve never measured it.

I have an ecoflow solar generator and the warranty is voided if its charged via a source that isn't a pure sine wave. I suppose I could daisy chain a dc to ac converter and then use a DC to AC pure sine wave inverter but I don't really like that idea.

Measure it.

Modified. The outlet in my ‘17 (350) and ‘20 (450) both were. They were both also limited to 300W or so. If it were pure sine wave, you can be damn sure the marketing department would have noted it.

If I had the right tool I would, was just seeing if anyone had already measured it.

The 300W is fine, I think in the Ranger it is actually 150W according to the manual. I figured they would advertise as pure sine wave if it was, just wanted to ask.

Then get an isolation transformer rated at K32!! Ok the thought of pure sine wave is impossible to create or prove, it’s simple physics unless you go cryogenic. Ok that said they are saying keep away from square wave looking chargers like a battery charger with no filters. You should be ok just using DC, or the trucks 110 AC.

Their problem is handling fast rise times for voltage regulation.. really you should be ok, if not then it was a wall socket problem at home. Seriously any modern inverter should be ok. Truck or not..

I think you’re worried over nothing if you plug it into your Ranger… Just an overstated disclaimer to refuse warranty..

Someone did put a scope on it in another thread - its a square wave. Marketing types like to call it a modified sine wave to sound good, but its just a pulse-width-modified square wave.

I tried an LED nitelite in mine to defeat the A.S.S and it fried almost immediately. A heated perfume thingy, without perfume installed, is working nicely. The perfume heater is just a resistive heating element, it doesn't much care about what kind of power it gets.

Many LED lights use a capacitor divider with a diode to get the right voltage and I think that type won't work with a square wave inverter. Many AC-DC power supplies won't be happy either.

You can get a 150W square wave inverter for about $20-30. It seems like Ford could have done a little better on a $40K truck. Same inverter is used on my Transit van, just useless in my opinion.

QCRanger, some chargers are unhappy with modified sine wave inverter power--they'll overheat or otherwise be damaged. Your best bet is to get a pure sine wave inverter and either plug it into a 12 V outlet or hardwire it. This Bestek one, for example, costs less than fifty bucks. I've had a number of Bestek inverters over the years (although not this particular model) and have never had a problem with one.

Note that while this unit is rated for 300 watts output, you probably won't be able to get that from one of the Ranger's 12 V outlets without either overheating the plug or blowing a fuse. But as long as your Ecoflow's charger doesn't need more than 150 watts or so, you should be fine... and you'll be safely within its warranty.
