Our editorial team weighed Jackery's published specifications and how it stacks up against similar products in the generators category. What stands out: Military-Grade Reliability, Pure Sine Wave Output, and Multiple Recharge Options. Where it falls short: 500W Continuous Limit and Solar Panel Sold Separately. That puts it at 8.7/10 on our WG Score – an excellent, well-rounded option.
Reviewed byTristanWhen the lights go out, the first question that comes to mind is usually: how much power do I actually need to keep my essentials running? The answer depends on what you want to power, a few lights and a phone charger, or a refrigerator and a CPAP machine. Based on the specs and user feedback for the models we reviewed, most households find that a portable power station with a capacity between 200Wh and 500Wh can handle a night or two of basic needs without breaking the bank. For more on sizing, check out our guide to portable power stations with solar panels.
What to Know Before Choosing Best Solar Generators For Power Outage
How much battery capacity is enough for a power outage?
Battery capacity is measured in watt-hours (Wh), and it tells you how much energy the generator can store. For a typical overnight outage, a unit like the Jackery Explorer 500 with 518Wh can run a 60W refrigerator for about 8.6 hours (518Wh ÷ 60W = 8.6 hours). If you only need to charge phones and a tablet, a smaller 256Wh model like the EcoFlow RIVER 2 will easily last through a day. Always match the capacity to the devices you plan to power.
What types of batteries are used, and why does it matter?
Most solar generators use either lithium-ion or LiFePO4 (lithium iron phosphate) batteries. LiFePO4 batteries, like the one in the EcoFlow RIVER 2, can be cycled over 3,000 times before reaching 80% capacity, which translates to roughly 10 years of regular use. Lithium-ion batteries, found in the Jackery Explorer 500, are also reliable but may have a shorter lifespan. For long-term emergency preparedness, a LiFePO4 battery offers better longevity.
Can I charge the generator with solar panels during an outage?
Yes, most portable solar generators accept solar input, but the charging speed depends on the panel wattage and the generator’s maximum input. For instance, the EcoFlow RIVER 2 can recharge in as fast as 2.3 hours with a 110W solar panel. The MARBERO M823 supports solar input up to 24V at 2.7A, which means a 60W panel would take roughly 4 hours to fully charge its 237Wh battery. If you want a system that includes a panel, the MARBERO 111Wh kit comes with a 30W panel included.
What can I run simultaneously with a 300W or 500W output?
The AC output rating tells you the maximum power you can draw at once. A 300W unit like the MARBERO M823 can power a small TV (50W), a laptop (60W), and a couple of LED lights (10W total) simultaneously, totaling 120W, well under its limit. The Jackery Explorer 500, with 500W AC output (1000W peak), can handle a mini fridge (100W) and a CPAP machine (30W) at the same time. Always add up the wattages of devices you plan to plug in to avoid overloading the generator.

Buying Guide for 2026
Capacity and Runtime: Matching Wh to Your Needs
The watt-hour rating is the most important spec for determining how long your devices will run. For example, the Jackery Explorer 500 has a 518Wh battery. If you want to power a 50W LED TV for a movie night, it will run for about 10.4 hours (518Wh ÷ 50W = 10.4 hours). For a CPAP machine that draws 30W, the same battery lasts about 17.3 hours. Always consider the total wattage of all devices you plan to connect, and remember that inverters have some efficiency loss (typically 85-90%).
Output Ports and Compatibility
Check the number and type of AC outlets, USB ports, and DC ports. The EcoFlow RIVER 2 offers two AC outlets (300W each) and USB-C, making it versatile for charging modern gadgets. The MARBERO M823 includes two AC outlets (one 2-prong, one 3-prong) and two USB-A QC3.0 ports for fast device charging. If you need to power a CPAP machine or a medical device, ensure the generator provides pure sine wave output, all models here do, which is essential for sensitive electronics.
Charging Speed and Methods
How fast can you recharge the generator after use? The EcoFlow RIVER 2 can be fully charged from an AC outlet in just 1 hour thanks to X-Stream fast charging. The MARBERO M823 takes about 6 hours via wall outlet. Solar charging times vary: with a 110W panel, the RIVER 2 recharges in 2.3 hours; with the included 30W panel on the MARBERO kit, the 111Wh battery takes about 3.7 hours (111Wh ÷ 30W = 3.7 hours). Faster charging means less downtime during extended outages.
Portability and Weight
If you plan to move the generator between rooms or take it camping, weight matters. The Jackery Explorer 500 weighs 13.3 lbs, while the EcoFlow RIVER 2 is just 7.7 lbs. The MARBERO M823 is also lightweight at 2.3 lbs (without panel). For more on lightweight options, see our off-grid solar generators roundup.

Frequently Asked Questions
Can I use a solar generator during a power outage without sunlight?
Yes, you can pre-charge the generator via a wall outlet before the outage. All models here can be charged from an AC outlet. During an outage, if you have solar panels, you can recharge during daylight hours. For tips on maximizing solar charging, see our article on solar panels for power stations.
How long does it take to charge a solar generator from a wall outlet?
Charging times vary by model. The EcoFlow RIVER 2 charges fully in just 1 hour. The Jackery Explorer 500 takes about 8 hours with the included AC adapter. The MARBERO M823 charges in approximately 6 hours. Always check the manufacturer’s specifications for exact times.
What is the difference between pure sine wave and modified sine wave inverters?
Pure sine wave inverters produce clean, stable power that is safe for sensitive electronics like CPAP machines, laptops, and medical devices. All generators in this roundup feature pure sine wave inverters. Modified sine wave inverters are cheaper but can cause buzzing or damage to some electronics. For sensitive devices, always choose a pure sine wave generator.
Can I run a refrigerator on a portable solar generator?
It depends on the refrigerator’s power draw. A typical mini fridge uses about 100W. The Jackery Explorer 500 (500W output) can run it for roughly 5 hours (518Wh ÷ 100W = 5.18 hours). The EcoFlow RIVER 2 (600W output) can run it for about 2.5 hours (256Wh ÷ 100W = 2.56 hours). For a full-size refrigerator (around 200W), only the Jackery Explorer 500 can handle it, and runtime would be about 2.6 hours. Always check the starting surge current, which can be higher.
