This trip wasn't about what the equipment said it could do. I wanted to know what it would actually do during several days in a wooded campground with changing sun, clouds, shade and normal everyday use.
My setup was a Jackery Explorer 2000 v2 paired with a Renogy 400W portable solar blanket.
The Jackery powered my 12V refrigerator while also handling my fan, phone, laptop, camera gear and other small devices.
And yes, I also experimented with my electric kettle.
That turned out to be an important part of the test. 😂
The Numbers
I wanted actual battery percentages rather than guesses.
Day 1, Tuesday
I arrived with the Jackery at approximately 93%.
With good solar, it reached 97% at 1:07 PM and 99% at 1:20 PM.
Day 2, Wednesday
At 10:31 AM, after running the refrigerator and fan overnight and using my laptop, I was at 78%.
Day 3, Thursday
I started the morning at approximately 67%.
By 11:37 AM, after normal use, I was at 51%, and I put the solar blanket out.
This became one of the most useful tests of the trip because the sky was increasingly cloudy.
With very little sun, the blanket produced only about 27–30 watts, roughly enough to offset what the refrigerator was using. The Jackery simply held at 51%.
Then the sun would break through.
Solar input jumped as high as 308 watts.
At 12:47 PM, the battery reached 55%.
Around 1:00 PM, it reached 56%.
At approximately 1:20 PM, I moved the blanket flat onto the ground in full sun. Within minutes I was seeing roughly 300 watts again, and the battery reached 59%.
At 1:30 PM, darker clouds were moving in and I called the solar experiment.
Ending battery level: 60%.
Despite intermittent sunshine and the refrigerator running continuously:
51% → 60% in less than two hours.
That impressed me.
Three Positions, One Important Lesson
I tried the Renogy blanket in three different positions.
On the picnic table, it was convenient, clean and capable of excellent production when the sun reached it.
Flat on the ground, it produced some of my strongest numbers when it had unobstructed sunlight.
On the hood of the van, it became useful when the sun shifted and other parts of the campsite moved into shade.
My conclusion was simple:
Follow the sun, not the clock.
If the blanket is producing well where it is, leave it alone. Move it when the shade tells you to, not because the clock does.
The Kettle Lesson
Then there was my electric kettle.
It can pull around 1,500 watts while heating, and I used it twice during the trip.
Could the Jackery handle it?
Absolutely.
Was using battery power to boil water the smartest choice in a heavily wooded campground when I had a butane stove sitting there?
Probably not. 😂
Those two uses likely accounted for a noticeable portion of my battery consumption.
For longer remote camping, my strategy became pretty simple:
Limited solar? Use butane.
Plenty of sun and battery? Enjoy the electric conveniences.
Last morning with plenty of battery left? I'm making coffee the lazy way.
Could I Stay Out Longer?
Based on this test, yes.
The refrigerator wasn't the problem. Charging small devices wasn't the problem.
The Jackery gave me enough reserve that I wasn't worried about running out of power.
By Thursday afternoon, I wasn't charging because I needed electricity. I kept the blanket out because I wanted to see what it could recover before the rain arrived.
For remote camping, this setup could support my needs for several days, especially if I reserve electricity for refrigeration, electronics, the fan and camera equipment and use butane for high-draw cooking when solar conditions aren't ideal.
There was one limitation to the solar blanket that had nothing to do with watts.
I won't leave it unattended.
A portable 400W solar blanket sitting at an empty campsite is simply too easy to grab and run.
When I leave camp, the blanket gets packed away and the Jackery takes over.
That's another reason I'm glad I chose the larger power station.
After three nights, I wasn't wondering anymore whether my system could keep up.
I had the numbers.
More importantly, I had learned how I wanted to use the system in the real world.
