RV Gadget Review: Jackery Solar Generator 1500


One of the most common questions I read on the various forums about RVs that I troll is about the use of CPAP machines overnight while boondocking. There are also a lot more folks on the road with their various “confusers” and other electronic whiz bangs and, of course, those need to be refueled as well. 

Of course, you could always get a traditional generator – but they’re noisy, smelly and require maintenance. Furthermore, few places allow you to run them at the time of night when you’d want to use a CPAP machine. So that solution is a no-go for many circumstances. 

Enter a device that has come on the scene called a solar generator. The solar generator is, quite simply, a battery, a way to plug things in to utilize that battery’s power and a way to refuel or recharge that battery. It’s that simple. 

So when Jackery offered to send me their latest and largest model, the Jackery Solar Generator 1500 (Jackery 1500 + 4 x SolarSaga 100W), I thought it would be a great opportunity to see if this could really do the job many want from it. 

What the Jackery Solar Generator 1500 is

Essentially, the Jackery product is a large 1,534-watt-hour battery enclosed in Jackery’s typical case giving you access to use that power almost any way that makes sense. 

On the front of the box are three 120-volt household power outlets, a single USB-C outlet, a traditional USB outlet capable of up to five volts or 2.4 amps, a USB outlet compatible with Qualcomm’s quick charge, and a typical “cigarette lighter” adapter capable of delivering 10 amps of 12-volt power. 

In addition, there is a display that shows power input and output and how much power remains in the battery. There’s also a calculated guesstimate as to how long the power will last based on current usage figures. 

Using this you could plug just about any 120-volt household appliance into it and operate that. For example, I plugged in a coffee maker, a coffee grinder, a pressure cooker, an Instant Pot and a toaster. Not all at the same time, mind you, but individually. The unit handled all of those without an issue. 

At the same time I could plug the very notebook confuser in that I use to write these reviews via the USB-C port and charge it. 

There are also two ports at the upper left of the front of this to charge the device itself. You could use the included wall charger to accomplish this, or I used the four 100-watt SolarSaga solar panels that were sent as part of the package to do so. 

Solar charging

My favorite way to replenish the power in this beast is to lay out the four Jackery SolarSaga 100-watt solar panels and let the sun provide my juice. 

To accomplish this there are two adapters that come with the device that let you plug in two of the solar panels to each adapter and then plug that adapter into the Jackery. In theory, this provides up to 400 watts of solar input. I was able to get up to 380 watts at the most and around 200 watts in less than ideal conditions. 

Each SolarSaga panel consists of two semi-flexible solar panels in a flexible case. The case snaps together like a briefcase using magnets and there’s a nifty handle at the top. At the back of each of these assemblies is a pocket which has the connector and wire to attach to the Jackery. Also there’s a hub with USB-C or USB ports, allowing you to use the panel to charge those devices. 

The flexible case that is the back of the panel also has a flip-out leg or stand on each side so you can position the panel to optimize capturing the sun’s rays. 

Charge times

Charging the unit from a low point to full took anywhere from 6–8 hours depending on the sun, the state of charge, and whether there was anything drawing current from the unit. 

There’s another thing I really liked about this unit: You could charge it at the same time as you were using the power, thanks to an MPPT controller in the unit. I actually plugged my travel trailer into the unit while the solar panels were doing their thing and ran the refrigerator in the trailer. 

The Jackery reported that, after a day of doing this, the unit was down to 89 percent of capacity so, basically, not bad. Power draw varied from about 120 watts to 180 watts, depending on where the refrigerator was in the operating cycle. Incoming power varied, as well, due to it being a cloudy day. It’s quite possible, depending on your draw, to use this package to operate many of the things in your RV completely off solar. 

Would it be possible to operate the AC unit? Sort of. If you use a SoftStartRV and this high-capacity Jackery unit, you could get about two hours’ run time from the AC. But you really wouldn’t want to have any other electrical loads at the same time. This is similar to running your AC with a smaller generator. 

Why Jackery

Jackery has made a name for itself as a company that provides an integrated solution. Everything they make is designed to work together to provide a solution for the customer. If you buy their main unit and their solar panel there is no question what’s going to happen – you plug the connector in and charge the unit. Simple. 

Their plugs plug in only one way and everything just works. The unit and the solar panels are designed to work together – and they do. 

There are other brands of these solar generators that are more component-based. Yes, you can use anybody’s solar panels. You can mix and match things. But how well they work together can depend very much on your understanding of the systems. 

You could also build a device that performed the same function for much less than the $2,699 list price of this device. But then you should know what you’re doing, as lithium batteries can get “explodey” if not managed properly. Buying an off-the shelf unit means you don’t worry about this. 

The downside

As many pluses as there were with this unit, there were also some things that really had me scratching my head. 

For example, the main unit wanted to be in a relatively temperature-moderate environment. In other words, electronics don’t like to be in freezing temperatures nor do they like to be extremely hot. 

The first few days I had this, the outside temps were close to 110°F. So charging it was a bit of an issue as the cables provided with the solar panels aren’t very long. Thus, the whole thing had to sit outside and the main unit worked to protect itself. Part of that was limiting incoming charge power. 

I would really like to see Jackery offer extension cables for this package so that I could keep the main unit inside and the solar panels outside the RV. 

While I respect the fact that all the Jackery bits work very well together, by the same token, it’s next to impossible to use solar panels that I already have.

But the biggest thing about this that troubled me was that the internal battery is only good for about 500 cycles. Some of the newer Lithium Iron Phosphate (LiFePO4) have charge duty cycles of up to 3,000 cycles, some even more. Once you’ve gone through all the cycles on this device it’s just e-waste. I wish Jackery offered some sort of a replacement/trade-in program for the batteries themselves. 

In summary

I can see the Jackery Solar Generator 1500 serving a lot of different use case scenarios. 

The most obvious one is the CPAP user who wants something silent that can handle 1-2 CPAP machines overnight. Depending on your CPAP unit, this could be your solution. It’s quiet, easy to recharge, and will run two CPAP machines for eight hours. 

This could also be a great solution for those who like to boondock and want to run appliances like coffee makers or hair dryers. It will handle those kinds of things. 

I could also see, with the group that I go camping with, this machine being pressed into use to run our Traeger barbecue. Plug the Traeger into the Jackery and throw the four solar panels out and you’ve got smoked venison by the end of the day. In fact, if my calculations are correct, you can run the Traeger and then still have enough juice to power two CPAP machines overnight. This does have a lot of stored energy. 

Furthermore, I will keep this unit in the house here in Northern California. Our local power company keeps settling lawsuits for burning down communities. Their solution is to simply shut off our power when things get scary for their shareholders. While I presently have been using a small generator to keep my refrigerator running, this unit will easily handle that task when this happens. Again. 

The good thing is, since it’s a battery-powered unit, it’s not announcing itself to the neighbors by rattling outside in the yard. I can keep the unit inside the house overnight, which means my refrigerator will be running overnight too. Not only do the generators come out when the power goes off up here, so, too, do the people who like five-finger discounts on generators sitting outside at night. 

Being dead silent also means you can run things in places where there are restrictions on the generator hours. Frankly, this unit inside the RV won’t make any noise and you can charge your computers, phones and all of that. 

Jackery makes a number of different units that offer this functionality but with different capacities. The 1500 that I tested is truly the beast of the bunch and will power a lot of different things. While the entire package, at $2,699 on Jackery’s website, is certainly not inexpensive, the simplicity of making the pieces work together along with the capacity of this device may make sense for some people.

I have a few of the smaller (a 160 and a 240) Jackery batteries a I think they are well made compared to some of the others on the market. These work well to charge phones, laptops, and camera batteries and they will also run the TV for a few hours. The problem is they are expensive and take all day to recharge. In regards to your set up, I think I would be more apt to buy a couple of quite gas generators rather than spend $2,700.00 on a Jackery. But thank you for the informative review.

Funny you mention the power outage. In SoCal, SDG&E had a program where they gave us (as in free) a similar product, a Goal Zero Yeti 3000 as part of a study that they were conducting. It too came with solar panels and various plugs for charging the battery. SDG&E called it a power generator. The 3000 ran our home refrigerator and deep freeze when SDG&E killed our power due to fire danger. The study consisted of them contacting us after the power outage. They wanted to know how great this thing was during the outage. I told them that it wasn’t that great because if you had to run something you needed a way charge it back up. When it’s overcast, solar won’t charge it up. I actually had to run my gas/propane powered generator to power up the house and charge this battery. What was nice was plugging in the items to the battery that I needed to run and then plugging the battery into a charge source. If that went out, then the battery kicked in and powered the stuff.

I have the Jackery 1000 watt unit and love it. I got it as the weight was low enough for me to easily carry and lift. I have used it when dry camping to power the tv and a fan.

Here’s what there website says! In the FAQ’s they don’t recommend doing this as they say it will degrade battery life?

I have the explorer 1000 and I like it, haven’t used it a whole lot yet. The 500 cycle battery life is a bit of a disappointment, but hopefully by then there will be replacement parts available.

Do a little research. Buy a battery, some panels, a charge controller, maybe an inverter. You’ll get FAR better bang for your buck. Solar “generators” (what a ridiculous misuse of that word) are mostly an overpriced scam.

The term generator for this is somewhere between misleading and lying. It doesn’t generate anything. It stores electricity like, you know, a battery. I wonder how many batteries and solar panels you can buy for that price. Plus a controller. I’m betting a whole lot more for less money.

Agree, this is a money making scam of the non-researcher. I can buy three quiet generators and a secure place to lock them up for a lot less than $2699. Even the very small generators produce more power than this battery pack and inverter. As P.T. Barnum said “there’s one born every minute”.

I get 100AH, 4S LiFESO4 banks for $400 (easily, all day long). For $2700, I can get SIX of those, and for $300 more put a fantastic inverter and/or lots of solar panels with it. Total non-starter for me!

On other news, I shot a YouTube video on how to make a 12>24V adapter for ResMed A10 CPAP for $5, and use my truck’s $50 jumper pack to run it for most of a week! Again, no multi-thousand dollar solution.

I have a Jackery 500 and 1 100 panel and it is more than enough for my 12v frig and electronics in my converted van.

For a true UNBIASED review of the jackery see “Will Prowse DIY solar power” on utube. He buys the products with his own money and torture tests them he also does strip Downs of the units. His opinion of the jackery is it is way overpriced for what you are receiving. You would be far better off going with a full solar system on your rig

Nice review. I’ll be looking at something like this, as I’m a Cpap user.

you would be much better off just buying a high quality/ high capacity back up battery designed for computers. These battery’s will last for 2-3 nights of c-pap use with no problem. If you recharge it with a solar panel during the day you can get 6 or more nights depending on the size and output of the panel or panels. I have used this method for a few years, It works well for me. And costs a whole lot less! And can be used to run a T V or the fridge if needed. I haven’t tried to run a coffee maker or other high draw appliances.
