Everyone is worried about the price of the larger power stations yet...

Why would you buy a Battleborn battery(cylindrical cells) for just under $1000 when you can buy almost three Ampertime(Eve cells) Zooms/redodo(Ganfeng cells or even Enjoybot(Gotion cells) for the same price?

Again..To each his own..LOL

If you live by the credo 'you get what you pay for' you would.

Because battleborn has a decent reputation and I have never heard of the others.
Given those as my choices, I'll stick with Battleborn!

I have read several technical reviews that solar generators provide very little power except for charging cell phones, laptops, etc. compared to their high cost. But they sure are pretty to look at when visiting RV and Outdoor Camping shows. Cheers to com

I would never buy a battleborn, but I have three Ampere Time LifePo4's from Amazon that are working absolutely perfect for me every day.

For his reviews of solar and battery technology and products, Will Prowse runs electrical tests for capacity, etc. then tears batteries apart to inspect details such as internal lead size, solder/weld quality, BMS and sensor capability, etc. He has panned a number of such as junk, and found a number of gems among the crowded field of companies making this gear. If you search for his youtube channel, you can quickly find both links to good gear at good prices as well as his reviews. He also has detailed plans for making your own systems, and changes recommended gear from time to time as he finds better options. I can recommend both his youtube channel and his book.

She's probably long gone.
Off the top of my head, 190W solar + you add another 100W, in December in AZ on a sunny day will barely harvest enough to run 110V fridge and critically important loads like lights, pumps and furnace. Need to measure duty cycle of the fridge. Might have to stop using coffee maker and microwave.

The easiest solution for technically naive would be replacing your marine batteries with something larger, if it fits.

Jackery has 2-posts red-black port to connect their proprietary 100W or 200W solar panel, however such a portable solution seems inconvenient. And ridiculously expensive @ $300 per 100W panel. And easily steal-able. And inefficient, can't charge on the road. And small, one half of usable charge of the pair of your marine batteries. This gizmo is more for a weekend warrior, think car camping.

Side BAR: Using electricity to heat water (as in coffee maker) makes no sense to me. You can save power by using your gas stove to percolate / press.....

My propane tank is fixed. That means I can't buy propane in low population areas--so I use electricity instead. The system upgrades I've done support my needs.

I should have been more specific of what we have and what we plan on doing. Our travel trailer is a 2022 Microlite 21FBRS. It came with a 190 watt solar panel on the roof with a 1000 watt inverter. We plan on spending January and February in Arizona and expect to do dry camping some of the time, especially at Quartzsite. My main concern is to keep my refrig running. It is a residential 12 volt rated at 11 Amps. How many watts of portable solar panels do I need in addition to the 190 Watts panel on my roof? the trailer has a solar panel plug so it it ready for additional solar panels. And I will use the stove to make my coffee so I wont need power for that. Maybe a little TV watching and interior 12 volt lights.


The using those overpriced portable battery packs are the wrong way of going about this.

Jackery 1,000 has about 40Ahr worth of battery, that's it.

You cannot directly hook the jackery (or any other portable battery/inverter) to your existing 12V battery. They have power limited 12V cig ports to max of 8A.

Some back of the napkin figuring..

To get any sort of "value" from those devices you must use the built in inverter.

The downside to this is the inverter eats up 15% of your portable battery capacity bringing that 40Ah down to 34Ahr..

Now you have 120V but you can't plug that 120V directly to your 12V battery..

So, now we must consider the power loss of your converter.. That is another 15%..

So now your 40Ahr portable battery/inverter now becomes a 28Ahr "generator" and 28Ahr isn't going to get you squat for added camping time.

So, $1000 for 28Ahr portable battery or add some extra batteries and solar to your rig?

$1,000 can buy you a lot of 12V battery and solar capacity.

Cheapest option is adding two GC2 6V batteries (wired in series to get 12V) nets you 210Ahr for $180, granted You don't want to 100% drain the GC2s but you can draw as much as 80% and not take much of a cut in battery life giving you 168Ahr of capacity to work with.

More expensive option is Lithium batteries, they are still a bit on the experimental side of life and expensive but they can pack a lot of energy in that package.. $260 can buy you one 100Ahr Lithium battery (gives you 4 times more capacity than the portable device) and the claim to fame is you can use all of the battery capacity..

Solar panels you can get 100W panels for $90 now days..

As far as battery capacity goes, I use a 10 cu ft residential fridge in my TT and one pair of 6V GCs (wired in series for 12V) gives 210 Ahr and that setup easily powers my fridge plus lights plus furnace overnight for 20hrs-24hrs before needing to recharge.. I do not have any solar..

Those portable battery/inverter things simply do not have enough battery capacity to make a meaningful difference and add in an inverter you didn't need since you already have an inverter.

The manufacturers of those portable battery/inverters have done a very good job appealing to the masses using terms like "generator" or "quiet power" "quiet generator" "clean power" Clean generator" while hiding the downsides like the more power you draw, the less time you get power, all the while beating you over the head with severely over inflated prices..

Wish I had though of that a couple of yrs ago, I could have been a billionaire by now by feeding off folks wishful thinking [emoticon]

Don't get me wrong, they can be somewhat useful, sort of like if you need some 120V power for a short time and don't wish to run 250ft of extension cords to get it to you..



This is the best answer on this tread - full of useful information.

The most important point to the OP or anyone looking at a portable battery, power source, your trailer already has that portable power source. The battery system, solar system, generator, or whatever you use is the same or better than something like a Jackery - so, why waste the money, invest to make your current system better. I don't care what the neighbors think, I run a generator, just long enough to charge my batteries or watch a movie. With 2 6V GC batteries, if I wanted more power storage, I would add 2 more 6v batteries. LiFePO4 would be better if I was a serious boondocker.
