The battery, although powerful while working, doesn’t hold a charge after the first few times. Lastly, the solar panel to recharge the generator is sold separately.
5. Renogy Phoenix Portable Generator
If you’re looking for a portable generator that includes the solar panels, then the Renogy Phoenix Portable GeneratorRenogy Phoenix Portable Generator is a great option. It has 20-watt monocrystalline solar panels, which are the most efficient kind you can buy. It’s lightweight at 12.8 lbs. Aside from the solar panels, you can also recharge the generator with AC power or your car’s battery.
This is an expensive generator because of the high quality of the included solar panels. Despite being made of high-quality materials, the solar panels charge the unit slowly. There are parts of the generator that do not seem to be made of durable materials. For example, the ports break easily with normal use.
6. Goal Zero Yeti Portable Rechargeable Generator
The Goal Zero Yeti 400 Portable Rechargeable Generator has a 428Wh lithium-ion battery that can power up to seven devices at once. It has a continuous wattage of 300 and a surge of 1,200, so it can handle small devices and appliances easily. It comes with two USB ports and two 12V DC ports. The LCD screen allows you to easily monitor the battery level at a glance.
This is one of the more expensive generators on the list, but its battery doesn’t hold a charge well. The solar panels that can recharge it are sold separately, which is an additional amount. Even though it says it can power seven devices at once, it doesn’t have many outlets and ports.
7. EF ECOFLOW River Portable Power Station Generator
If you want a generator with a wide variety of outlets and ports, then you should consider the EF ECOFLOW River Portable Power Station Generator. It has 11 power generator outlets: four USB, two USB C-type, two AC outlets, two DC outlets, and one 12V car port. The generator is lightweight at 11 lbs. and is quite portable. The battery can hold a charge for up to a year.
This is another pricier option that doesn’t include the solar panels. You’ll have to spend an additional amount if you want to charge your generator that way. Many people use portable generators to power a CPAP machine when they go camping, but this one is not able to. It takes a long time to recharge the battery once it finally dies.
8. Kalisaya Portable Solar Generator System
The Kalisaya Portable Solar Generator System has 384Wh of power, which is powerful enough to power small devices and appliances. Unlike many of the other generators on our list, this one includes a 40-watt monocrystalline solar panel. It has four USB quick-charge ports and two DC ports, which should accommodate most small devices. It allows for remote system monitoring of your generator with a smartphone app, so you can check in while on the go.
The solar panel on this one, though made of high-efficiency mono-crystalline panels, is not that powerful. As such, it takes a long time to recharge the battery once it’s been completely depleted. There isn’t an AC outlet included with this generator, so you’ll need to buy a converter. It’s also difficult to find this mode of generator in stock.
9. Aeiusny Solar Generator Portable Power Station
The Aeiusny Solar Generator Portable Power Station is one of the most lightweight generators on our list at only 7.49 lbs. It has 296Wh to power small devices and appliances, including CPAP machines, which is great if you need one as an emergency backup or while going camping. It has numerous ports: three AC outlets, two DC ports, and four USB ports. Compared to many others on our list, it’s relatively inexpensive.
It takes a long time to recharge the battery, though — with the solar panels, it takes 10-15 hours in full sun. The panels are also sold separately. The battery dies after only a few uses, so it’s not very long-lived. This also isn’t one of the most powerful generators on the list won’t charge your devices as many times.
10. PRYMAX Portable Power Station
The PRYMAX Portable Power Station has 298Wh and can recharge your small devices several times and keep a CPAP machine running for four nights, which is great for camping or emergencies. It’s extremely lightweight at only 6.5 lbs., so you can easily take it with you. It has numerous ports, so you can easily charge all your devices without having to buy new cords or a converter kit.
None of the ports are quick-charge, though. The battery itself takes a long time to recharge too. The solar panels are sold separately, so that’s an additional cost. The power supply also heats up to the point where it seems like it will overheat when charging, which is a safety concern to be aware of. The generator must also be kept cool and does not run well in extreme temperatures. Lastly, this isn’t the most powerful option out there.
There are many things to look for when shopping for solar generators. We’ve included a buyer’s guide so you can feel more informed when you go to buy your new generator.
Types of Solar Panels
There are three types of solar panels used by solar-powered generators: mono-crystalline, poly-crystalline, and thin-film.
Mono-crystalline panels have the highest efficiency rates at 15-20%. They also operate better in high temperatures than the other panels. These two factors mean that these are the priciest panels. They are made from a single crystal.
Poly-crystalline panels have a 13-16% efficiency rate. They work fairly well in high temperatures, but not as well as mono-crystalline panels. They are made from many crystals. Because they are only slightly less efficient than mono-crystalline panels and less expensive, they are the most popular choice.
Thin-film panels are the least expensive option of the three. They’re also the least efficient, with a rating of only 7-13%. They also require a larger area of coverage than mono- or poly-crystalline panels.
For generators, the battery capacity is measured in watt-hours (Wh). It’s important to look at the watt-hours of the devices and appliances you need to be powered by your generator. This way, you can determine how many total watts you’ll need from your solar generator.
The inverter rating of a generator goes hand-in-hand with the battery capacity. It’s the maximum number of watt-hours you can pull from the generator at one time. You have to look at the inverter rating and battery capacity together, though. If you have a large inverter rating, it won’t matter if the battery capacity is small. For maximum efficiency, look for generators with a 1.5:1 watt-hours/inverter rating. This means you want your battery capacity to be 1.5 times that of your inverter rating.
Weight is a major factor in how portable a generator will be, but it also depends on the features of the generator. For example, if a generator has a handle and wheels, it makes it easier to transport even if it’s very heavy. Be sure to research the weight of each generator, as well as how easy each one is to move around.
Extra features can help you decide between two similar solar generators. Many on our list have great features, such as LCD monitors that display critical information at a glance, wireless connectivity to apps on your phone, and the ability to connect extra panels if needed.
The SUAOKI EC03804D-M Solar Generator is our best overall choice because it has a large battery capacity of 500Wh. It’s made for sensitive devices like computers, smartphones, and small appliances. It allows you to recharge it in three different ways, which is very convenient.
The Jackery Portable Power Station Solar Generator is our best value choice because it’s extremely lightweight and portable. It weighs less than 4 lbs., so you can easily bring it along with you. It’s made for sensitive devices, so you can charge your phone, tablet, laptop, and other small electronics.
We hope our reviews and buyer’s guide have pointed you in the direction of the best portable solar generator to meet your needs.
