Solar generators are the perfect addition to your camping or emergency bin, and no matter the size, the best solar generator mixes portability, lightness, and durability with a competitive price.
Let’s look at some of the best solar generators on the market today. Whether you want to bring it camping, use it in your home, prepare for an emergency, or all three, these sweet little packages can cover all your needs.
At the end of our list, we also answer some FAQs about solar generator size, battery type, and equipment. But before we get started, what exactly is a solar generator anyway?
A solar generator is simply a box that contains a battery and an inverter, sleekly designed so you can charge appliances directly off the box. Unlike gas generators, solar generators are quiet, easy to handle and transport, and safe to bring indoors. They’re the perfect option for a week of camping or to simply include in your emergency cabinet.
Inside the generator, the battery stores the electricity and the inverter converts that electricity into AC for your appliances. These solar generators typically have several outlets for different equipment: AC outlets (just like wall outlets in your home) as well as a few USB outlets for your phone and tablet, and finally a few DC outlets for gadgets designed for travel or camping.
You can typically charge your generator via a solar panel (which can be integrated into the generator, but is usually sold separately), a wall outlet at home, or while driving.
If you want to prepare for long-term emergencies or a week of camping, a solar panel allows you to continue using solar generator without any other power source, but usually isn’t as fast as simply plugging it in at home.
Solar generators come in all sizes, from little 150 Wh babies to keep your phone charged on a weekend camping trip, to 1,500+ Wh that can run larger appliances. The best solar generators are durable, easy to use, well-priced, and enjoy great reviews from customers.
Below, we’ve highlighted eight of our favorites, four smaller options (150 – 500 Wh) and four large options (1000+ Wh):
Let’s dig into each of these generators a bit more, starting with the smallest and moving up from there.
These solar generators store between 150 and 500 watt-hours of electricity, enough to power all your gadgets for a weekend camping trip and your CPAP for a night or two, depending on the size.
Prices range from $200 to $500 depending on the size and features of each product.
Quick Look: 150 Wh capacity, 150 W peak, Lithium-ion battery, 2 AC outlets, 4 DC ports, 4 USB ports, 18 month warranty
Number of Laptop Charges: 1.2 charges (based on a laptop charging for 2 hours with a 65 watt charger)
Suaoki’s 150 Wh portable generator is the most portable option on our list. At just 150 watt-hours of capacity from its lightweight lithium-ion battery, this generator weighs just 2.9 pounds and measures 7”X4”x5”, making it small enough to throw in your backpack for an all-day picnic in the park.
With 2 AC outlets (one 3 prong, one 2 prong), 4 DC ports, and 4 USB ports, you and your friends can keep your phones, speakers, and other small items charged. The 150 watt-hour capacity is more than enough to charge up a few phones and a tablet each day, but not much more than that.
The generator can be charged at home, in the car, or via a solar panel. Suaoki recommends a 60 to 100 watt panel to efficiently charge the battery and they also claim that, in full sun, a 60 watt solar panel will charge the battery bank in 6 to 10 hours. The generator actually includes an MC4 to DC port adapter, so you can just buy a solar panel and plug it in without purchasing any extra equipment.
Suaoki provides an 18 month warranty for the generator and customers report that the company is quite easy to work with if something goes wrong. People use these little generators for all sorts of situations: road trips, car camping, and emergency power outages.
Some users have complained it doesn’t power a CPAP for more than a few hours, but that’s just because they more than likely don’t fully understand the power needs of CPAP machines, which need much more electricity than this small unit can provide. Again, this generator is for small gadgets, not larger equipment.
Most customers though love the convenience of backup generator you can simply throw in a backpack, and praise the build quality and styling.
Bottom Line: A well-priced and extremely portable backup generator perfect for keeping phones and tablets charged up. However, if you’re looking to power a real energy-hogger, you’ll need to move up in capacity.

Quick Look: 210 Wh capacity, 150 W peak, Lithium-ion battery, 1 AC outlet, 2 DC ports, 4 USB ports, 12 month warranty
Laptop Charges: 1.6 charges
One of the coolest solar generators out there. If you want to impress friends and feel like a spy all at one time, check out Renogy’s 210 Wh Solar Generator Suitcase. When closed, it looks like any other hard-sided plastic case used by a musician or cameraman. Upon opening, however, you find a 20 watt solar panel with a hidden lithium-ion battery tucked inside!
While more expensive than other similarly-sized generators, the Renogy Phoenix is intelligently designed and well-built and is one of the most-loved products on our list.
The 210 Wh battery is enough to charge up your phones, tablets, DSLR cameras, laptops, and other gadgets, but with a peak power rating of 150 watts, there’s not enough juice to keep energy hogs like a coffee maker or blender going.
The integrated 20 watt solar panel can certainly keep the small battery charged up, but be prepared for a wait, as one customer reported it took 10 hours for the solar panel to fully charge the battery under decent sunlight. If you want to speed that process up, you can also connect an auxiliary solar panel – up to 120 watts – to slash that charge time to just a few hours.
A small LCD screen just under the handles shows the sun exposure level, so you can find that perfect spot for the fastest charge, as well as the current battery level. You can also charge the unit at home or in the car with the included AC and DC inputs.
Out of all the solar generators on our list, customers probably love the Renogy Phoenix the most! It’s sleek, lightweight, and easy to use. On top of that, users appreciate the rugged build quality and use the unit for natural disasters, emergencies, and just a weekend out camping.
Bottom Line: You’ll have to dish out a bit more cash for this all-in-one unit, but you’re getting one of the coolest – and most well-built – products on our list.

Quick Look: 288 Wh capacity, 500 W peak, Lithium-ion battery, 3 AC outlets, 4 DC ports, 4 USB ports, 18 month warranty
Laptop Charges: 2.2 charges
Moving up our list, we come to Chafon’s 288 Wh solar generator. A bit larger than the previous two generators, the Chafon includes enough capacity to charge your smartphone 20 times and a your laptop a couple times.
Still, even with this larger size, the Chafon is quite portable, with dimensions of 5”x4”x11” and a weight of just 7.5 pounds. The unit includes an integrated handle on top to easily throw it in the back of the car.
If you’re looking to charge multiple items at once, the Chafon is a great option. On one side, you’ll find three grounded AC outlets (ie 3-prong outlets), with four DC outlets and four USB outlets on the other side.
A simple LCD screen keeps you updated on your current battery life. Chafon notes that charging via an AC wall outlet takes 5 hours, charging in a car takes 7 hours, and via a 100 watt solar panel takes 14.5 hours. The unit comes with all the adapters you need to charge: AC wall outlet, DC car charger, and an MC4 solar adapter, as well as a DC output cable.
The manufacturer officially recommends a 40 to 100 watt solar panel, though the max the generator can handle is 120 watts. Obviously, the larger your solar panel, the shorter the charge time and there are many 80-100 watt foldable solar panels that find a nice balance between power and portability.
Unlike many small solar generators, the Chafon includes a pure sine wave inverter, not a cheaper modified sine wave inverter. Practically speaking, this means you’re able to charge sensitive electronics like some power tools, older CPAP machines, and some laptops. Pure sine wave inverters are certainly a step up in quality and most of the nicer and/or larger solar generators include them.
Like other solar generators, customers use the Chafon generator for camping, emergencies, in the car, and even for running lights during outdoor filmmaking. Many report that charge times are accurate, the unit is lightweight, and just works like a solar generator should.
Bottom Line: The Chafon 288 Wh generator stores enough energy for all the gadgets you’d want to keep topped up and with 500 watts of peak power, you’ve got enough juice to even recharge more energy-heavy items like power tools and the like. A great balance of power and portability.

Quick Look: 500 Wh capacity, 300 W peak, Lithium-ion battery, 2 AC outlets, 3 DC ports (including 1 car port), 3 USB ports (including 1 USB-C port), 24 month warranty
Number of Laptop Charges: 3.8 charges
At 500 watt-hours of energy capacity, the Suaoki G500 is the largest on our list of small solar generators. With 500 Wh at your fingertips, you can power up speakers, projectors, phones, tablets, laptops, and even a mini-fridge – though only for about eight hours or so. A few customers even use the device for their CPAP machine, with one user noting it lasts two nights before he needs to recharge.
Like all higher-end solar generators, the Suaoki G500 includes an integrated pure sine wave inverter, as opposed to cheaper modified sine wave options. This allows the G500 to charge sensitive electronics like CPAPs, power tools, and some electronics.
You can charge the generator at home, in the car, or via solar (120 watts max). While it has fewer outputs than others on the list, there’s actually a wider variety, as you have three USB ports including both a high-speed and USB-C port, three 12V DC ports including a car port, and two AC 3-prong outlets.
On the input side, there’s an adapter charging port and a dedicated solar charging port (which are Powerpole connectors). The kit includes a solar MC4 charging adapter/cable, car charging cable, and standard adapter.
At 24 months, the Suaoki G500 has the longest warranty of all the smaller solar generators on our list. Customers report excellent customer service should something go wrong. The low weight, variety of outputs, and high quality are also big wins according to users.
Bottom Line: A pure sine wave inverter and enough capacity to keep your finest gadgets topped up and running. Tack on the excellent customer reviews and the longer-than-most warranty and you’ve got a fine mid-sized solar generator. If you’re hoping to keep an armada of small to medium-sized gadgets topped up, the Suaoki G500 can handle it.

Now let’s move on to the larger solar generators. These come in at 1000 to 2000 watt-hours of capacity and are designed for heavier use than the products above. At this size, you have enough juice to power basically everything in your camp: phones, tablets, lights, coffee makers, water pumps, and anything else within reason. Of course, with all this capacity comes cost. Be ready to spend $1,000 to $2000 on these kits.
Being 2x to 8x larger than the smaller generators above, these large solar generators aren’t really designed to throw in a backpack. Instead, they’ve got wheels or two handles. Instead of a shoe box size, think more like an ice cooler.
Let’s take a look at our four top choices for large solar generators.
Quick Look: 1000 Wh capacity, 900 W peak, Lithium-ion battery, 2 AC outlets, 1 DC port, 2 USB ports, unknown warranty
Laptop Charges: 7.7 charges
The Peppermint Energy Forty2 Pro+ is another suitcase-styled solar generator. The reviews aren’t quite as good as Renogy’s solar suitcase and there are certainly some quirks, but whereas the Renogy’s capacity is a mere 210 Wh, Peppermint Energy offers the 1000 Wh Forty2 Pro+ and the 2000 Wh Max. If you’re dead set on a solar suitcase, this is your only option if you want something larger.
At 1000 Wh, you’re able to charge all the gadgets you’d like with energy to spare, and it can even handle big ticket items like power tools and laptops. Unfortunately there are a few quirks though with the excellent design.
First and foremost, the Forty2 Pro+ weighs in at 62 pounds, so it’s like carrying around a big, heavy, oversized briefcase. The integrated handle looks pretty beefy, so we’re not worried about it breaking, but we know we’d get tired of lugging that thing around all the time. One reviewer noted that it does get tiring carrying the large suitcase and that wheels and handle would be nice upgrades in the future.
Secondly, the integrated inverter is a modified sine wave, instead of a more expensive pure sine wave inverter typically found in higher-end solar generators like this one. Some electronics, like CPAP machines, power tools, and some laptops, can’t run off modified sine wave inverters, so research your equipment’s needs if you’re worried.
Next, there’s no option to charge via 12 volt DC, ie while driving. You can of course charge via the solar panels as well as a wall plug, either of which should take about 6 hours to fully charge the batteries, but there’s no car port.
Lastly, tthe Forty2 Pro+ doesn’t have quite as many output ports as the other solar generators on our list, with only 2 AC outlets, 2 USB ports, and 1 DC port. If it’s just you using the device, you’ll probably be alright, but if you’re blessing the rest of the group with your amazing toy, you’ll probably have to take turns sharing the outputs.
There’s little info available on the finer details of the product, and one buyer even complained that even the box didn’t include any warranty info, so do your homework beforehand. Still, the Forty2 Pro+ looks great, works as a solar generator should, and is quite unique, landing it a spot on our list.
Bottom Line: Peppermint Energy’s Forty Pro+ looks great and functions well, but there’s a few kinks they need to work out, namely around the weight and the inverter type. Even still it’s a great option if you want a sleek, all-in-one solar generator package.

Renogy is a well-known manufacturer of small-scale solar and battery equipment, so it makes sense they’re on our list of best solar generators. Their Lycan Powerbox is a modern, well-designed product with two wheels and a suitcase handle to pull it along after you. And at 60 pounds, you’re going to want wheels.
With 1,075 watt-hours of energy capacity and 1200 watts of peak power, the Lycan Powerbox can power just about anything you can throw at it. Of course, it’ll power all the usual gadgets like phones and tablets, but it’s also powerful enough for hair dryers, toasters, and other high energy use devices. At 1,075 Wh of electricity storage, you’d be able to use that 1,000 watt toaster for over an hour straight!
The high capacity paired with the pure sine wave inverter (as opposed to cheaper modified sine wave inverters) also means CPAP machines and other sensitive electronics aren’t an issue at all for this thing.
The inputs and outputs are easily accessible right on the front of the box, with 4 AC outlets (the most of any generator yet!), 4 USB outlets, and 4 DC ports. On the input side, there’s a shared solar/car port (Powerpole) and an AC port. The LCD screen gives you a battery reading and notes whether you’re outputting AC or DC electricity.
Solar panels can be connected in series, up to 36 volts to allow for faster charging. The Lycan also includes an MPPT controller (aka Maximum Power Point Tracking), which allows even more efficient charging – a huge plus for this unit.
Customers have generally favorable comments on Renogy products and the Lycan Powerbox is no different. Users praise the Lycan’s value, fast charging capabilities, and performance, but some warn that the integrated cooling fan can be loud and at least two customers have complained that their units unexpectedly turn off sometimes.
That’s not something you want to hear, but the Lycan’s still a great option, especially with Renogy’s well-known excellent customer service.
Bottom Line: Renogy’s Lycan Powerbox is a well-designed solar generator. The wheels and collapsible handle make for easy transport and the capacity is high enough to power almost any gadget you could need on a camping trip or in an emergency.

Quick Look: 1200 Wh capacity, 1500 W peak, Lead-acid battery, 2 AC outlets, 2 DC ports (car ports), 2 USB ports, 24 month warranty (6 months for battery), 80 watts of integrated solar panels
Laptop charges: 9.2 charges
Wagan’s ePower Cube is probably the most unique product on our list. Similar to the briefcases, it’s an all-in-one solar generator, complete with 80 watts of integrated solar panels that slide and fold out of the top of the generator. Unlike the other solar briefcases though, this generator uses lead-acid batteries instead of the more expensive lithium-ion, so the price is much lower out of the box.
In fact, every other solar generator on our list uses lithium-ion batteries instead of lead-acid, and this is the biggest difference between the Wagan ePower Cube and all the others. Lead-acid is cheaper, but manufacturers consistently choose lithium-ion for portable solar generators because they weigh about 2/3 less than similarly-sized lead-acid batteries, have more usable energy, recharge more quickly, and last longer. As you can see, there are a lot of benefits to lithium-ion!
Because of the lead-acid battery, the Wagan weighs a full 122 pounds, by far the heaviest generator on our list and about 2x as heavy as the simarly-sized Renogy generator above. Since it’s built like a cooler, replete with wheels and a collapsible handle, moving the generator around isn’t a huge hassle, but lifting it in and out of cars is certainly going to get annoying.
One buyer warned the generator must be on a flat, smooth surface for the wheels to work and if you’re not careful, the handle can snap from the heavy weight. As such, consider the Wagan ePower Cube more for emergency power around the home and maybe the occasional camping trip.
Weight aside, the real benefit of the lead-acid battery is the low cost, and this solar generator comes in hundreds of dollars less than other products here. If you’re looking for a larger solar generator at the lowest price point, the Wagan is probably your best bet.
The integrated solar panels provide 80 watts of solar power, which should be enough to efficiently recharge on a sunny day, but you can also an additional solar panels as well as batteries for greater capacity.
Like the other large generators we review, the Wagan’s 1200 Wh capacity and 1500 watt peak power is more than enough to run appliances like hair dryers and blenders, laptops, and all your gadgets, but with just a modified sine wave inverter, as opposed to the more expensive pure sine wave inverter, some sensitive electronic gadgets – especially older models – simply won’t work with this device.
Bottom Line: While it certainly has a few design flaws, namely the heavy weight, the Wagan ePower Cube is a convenient, all-in-one solar generator that comes in at a much lower price point than any of the others on our list.

Quick Look: 1425 Wh capacity, 1500 W peak, Lithium-ion battery, 2 AC outlets, 4 DC ports, 4 USB ports (including 2 USB-C ports), 6 month warranty
Laptop Charges: 11 charges
Goal Zero is the supreme leader of solar generators for the outdoor enthusiast. Their products are more expensive than others, but they’re well known for their ruggedness and dependability. Their products are designed for heavy outdoor usage and as such they’re built to last.
The Yeti 1400 is the largest solar generator on our list, at 1425 Wh of capacity. With this much storage, as well as the pure sine wave inverter’s 1500 watt peak power, you can run just about everything you’d need on a camping trip or in emergencies: phones and tablets, laptops, power tools, coffee makers, CPAP machines, blenders, TVs, and medical devices. With 1425 Wh of power, you can keep a typical CPAP machine going for five to six nights without recharging.
The generator includes two 3-prong AC outlets, 4 USB ports (including 2 USB-C ports), and four DC ports (including two smaller ports, one car port, and one Anderson Powerpole Port). You can recharge the generator via solar panels or an AC wall outlet, which takes 25 hours.
If you want a faster recharge, you can hook multiple solar panels up, but you’ll need adapters as Goal Zero products can’t handle the higher voltage of solar panels connected in series (ie daisy-chained together).
At just 44 pounds (thanks to the lithium-ion battery) and with beefy handles on either side, the Yeti 1400 is easy to put in the back of the car, though some users do note that wheels would be a nice touch, similar to other large generators. A small storage area on top of the unit allows you to store cords for easy access later on, a nice feature that only this generator includes.
The Yeti also comes with a Wi-Fi mobile app that allows you to remotely check battery life and turn ports on and off, a fun addition, though users complain that setting up the Wi-Fi connection is a serious pain. Beyond the WiFi setup issue, customers report that the unit is easy to set up and carry and as expected, is quite rugged – perfect for camping and emergencies.
Bottom Line: If you’re an outdoor enthusiast looking for a large, heavy-duty generator that your whole camp can use, the Yeti 1400 is it.

Now that we’ve gone through our list of the best solar generators, let’s answer a few questions that we all have, starting with the benefits and drawbacks of solar generators over gas generators.
Of course, solar generators also have their downsides.
Both gas and solar generators have their places. If you just want a power source in emergencies or for week-long camping trips, a solar generator is perfect for your needs, as they’re quiet and safe to bring inside. If you’re looking to run power tools directly off your generator while you build your off-grid cabin though, a gas generator probably makes more sense.
Here’s a few more answers to commonly asked questions around solar generators.
You should base the size of your solar generator on your energy needs. If you just want to keep your smartphone and tablet charged during an emergency, a generator that is 500 Wh or less should do just fine. If you’re looking to actually power appliances, like a CPAP or coffee maker, you’ll probably want something 1,000 Wh or more.
Actually figuring out your exact energy needs is an easy, fun problem. Just make a list of everything you want the generator to power, their wattage, and how long you expect to use them on a single charge from the generator. Your list will likely look something like this:
Most manufacturers recommend only using 80% of a lithium battery’s full capacity, so let’s account for that as well:
So for the example above, you’d need at least a 465 Wh generator, so the Suaoki G500 above would be the perfect option. Open up a Word Doc and make your own list!
Manufacturers always note their generators’ watt-hour capacity as well as their peak power, measured in watts. While they sound similar, they actually measure two very different facets of the generator:
Watt-hours (or Wh) is a measure of the battery’s capacity. If your battery is a bucket, this tells you how large the bucket is. A 1,200 Wh battery stores more than a 120 Wh battery, and as such could run a gadget 10x longer than the latter.
Watts is a measure of the inverter’s peak power. If watt-hours is the bucket, consider watts as the diameter of the bucket’s opening. In other words, how much electricity it can provide at one time. A 1500 watt generator can provide 3x more electricity at one time than a 500 watt generator. High-energy items like hair dryers and coffee makers require anywhere from 1,000 to 2000 watts just to turn on, while laptops and smartphones only need 15 to 60 watts.
Both your capacity (watt-hours) and peak power (watts) are determined by your energy needs, so take a look at your gadgets and make the call.
Most solar generator use lithium-ion batteries to store electricity. While they’re much more expensive than lead-acid batteries, their unique benefits make them the perfect choice for portable solar generators.
First, they’re extremely compact and lightweight. Lithium batteries are typically 1/2 to 1/3 the weight of similarly-sized lead-acid batteries. Needless to say, this is quite nice when you’re lugging your generator in and out of cars all weekend.
Second, lithium-batteries can be discharged down to 80% of more of their total capacity, compared to lead-acid’s recommended 50%. This gives you more usable energy than a lead-acid battery with a similar capacity.
Third, they’re able to charge much more quickly than lead-acid batteries, a nice feature while driving or running late to that tail-gating event.
Lastly, lithium batteries don’t produce noxious fumes like lead-acid and don’t use any caustic components inside, so they’re generally a safer option.
The downside to lithium, of course, is its high sticker price. However, considering all the benefits above, we think it’s an easy choice to make.
All solar generators above can be charged via solar panels or a normal AC outlet like you have in your home, and most can be charged via a DC car charger as well. If you’re going on a weekend camping trip, simply charging your generator before leaving the house should be enough, depending on the size of the generator and your energy needs while out in the wild.
If you’ll be out for an extended trip, a solar panel is a good investment. A few of the solar generators above include solar panels integrated into the generator, but most require you to connect a separate solar panel.
The size of the panel depends on how large your generator is and how quickly you want to recharge the batteries. The larger the generator, the more solar panel you need, but 60 to 80 watts for the smaller generators and 120 to 180 watts for the larger units should let you recharge fairly efficiently. Manufacturers will typically recommend a specific panel size, so take a look at the product manual before making any purchases.
We hope you enjoyed out list of the best solar generators for 2019! Let’s take a look at our list one more time:
In an emergency or while camping, these generators really do pull their weight, as they’re powerful, quiet, and easy to use. Now all you need to do is calculate your energy needs and pick the best solar generator for you!
