EcoFlow Portable Jerry Can. Does this make sense?

I think I forgot an important part noted in a few posts:

Is this true? I suspect I need the ground..

That might work, if the problem is ground rather than power quality. Just make sure you don't plug that little doohickey into a home electrical system.

Thanks! Ordered. Keep you posted.

Unfortunately at that price point it probably doesn't include a sine wave inverter, meaning a lot of sensitive devices like chargers won't want to work on it. It is probably failing on power quality.

Also, keep in mind that even if you got it connected to the car, charging the car with it would mean running it at > 1.0C discharge, which will wear out the internal battery real fast. Best case scenario would be that you would charge all day from solar, then connect to the car and charge it for ~1hr, and get about 1kWh into the car for two days of work. You could probably just push the car by hand and get further than that in a day of work...

Experiments like these really show how much energy cars take - most people don't realize that their car is the most energy intensive thing they own by a big margin, all those details are hidden when using gasoline, but very apparent when using electricity which is easier to compare with the other things in our life. A car, even a very efficient EV, requires a lot of energy, and it isn't easy to make and store that much juice.

exactly......

rolling down the highway at 60mph on a flat road requires about 20kW of power.... 20 vacuum cleaners running at the same time. Putting Energy in at 1.2 kW doesn't get you very far very fast.

The other way to look at is to think about how much Solar it takes to support a typical L2 charger if doing a direct charge... about 7kW... which is about 18 full size residential solar modules.

power x time = energy

ordered what?

It is an exercise in futility to try to charge a BEV with a 1 or 2 kWhr portable and less than 1500 watts of Solar. Moreover, a cheap modified-sine Inverter may not put out acceptable power even after you add a ground rod.

I am basing testing on this dudes video:

that dudes setup can't possibly be effective for more than about an hour... Yielding maybe 1 kWhr of Energy before it sucks the portable battery empty.

To have a continuous L1 charge at 1200 watts, you'd need at least 1500 watts of Solar to 'pass thru'. This means a lot more solar, a much bigger charge controller, and a good pure-sine inverter with a solid ground to satisfy the charger.

I completely get what you are saying. Purely a test for what appears to be a $20 part (ground bonding plug) Again, main reason for Jackery is keeping a fridge going (which it can do) and camping/remote power tool.

read thru the Jackery specs carefully.... unless it says 'pure-sine', and gives quality power (60hz +/- .05hz, 120v +/- 5%), then I would not risk using it with expensive electronics like a charger or modern refrigerator.

So, I did the test with Jackery 1500 and 4x 100 watt panels.

There should be no surprise that in a span of ~1hr 15 min, my genny at a starting of 84% was drained. There was no increase in the car %. However, the miles/range went up by 3. Couple of points in the experiment:

1. You do need the ground plug with a power bar to charge. You cannot your car charger directly to the genny. I used this one:

2. Panels were producing 400W steady but this obviously cannot keep up with the 1200 watt draw
3. What was interesting was that when the genny was sub 10% it basically died and charging stopped as well as output. I am reaching out to Jackery to find out what happened.

Conclusion: No big shocker here. The Youtube videos suggesting a Jackery or equivalent can be used as an EV gas can are not very useful. Sure, you can charge. But, it will take you about 2 weeks to get enough to drive to the corner 7-11..
