Imagine you’re on a weekend camping trip, and your phone dies right when you need to snap a photo of the sunset. Or a sudden storm knocks out your power at home, and you’re scrambling to keep your laptop charged for work. That’s where a portable solar generator comes in, offering quiet, renewable energy without the fumes or noise of a gas generator. In this review, we’ll focus on the MARBERO 237Wh solar generator with its included 60W panel, but we’ll also compare it with the larger Jackery 1000 v2 and the compact MARBERO 111Wh model to help you decide which fits your lifestyle.
Buying Guide: What to Look for in a Solar Generator
Before you click “buy,” it’s helpful to understand the key specs that separate a great solar generator from a dud. Here are the four criteria we used to evaluate these products, and you should too.
Battery Capacity and Output Power
Battery capacity, measured in watt-hours (Wh), tells you how much energy the unit can store. The MARBERO 237Wh is a mid-range option, enough for small devices like phones, tablets, and a mini cooler for a night. In contrast, the Jackery 1000 v2’s 1070Wh capacity can power a mini fridge or even a CPAP machine for hours. Output power, in watts (W), determines what you can plug in. The MARBERO 237Wh’s 300W output handles most small electronics, but not high-draw appliances like hair dryers.

Solar Panel Efficiency and Included Panel
Solar panels are rated by their conversion efficiency, and the higher the percentage, the faster you’ll recharge. Both MARBERO models boast 21.5-23.5% efficiency, which is solid for the price. The included 60W panel on the 237Wh model is a nice bonus, as it lets you start harvesting solar energy right out of the box. The Jackery 1000 v2 comes with a 200W panel, which is significantly more powerful and can recharge the battery in about 6 hours, versus a full day for the smaller panels.

Portability and Weight
If you’re hiking to a campsite, every pound matters. The MARBERO 111Wh is featherlight at just 2.3 lbs, making it perfect for backpacking. The MARBERO 237Wh is still manageable, but at around 5-6 lbs, it’s better suited for car camping. The Jackery 1000 v2, weighing 23.8 lbs, is a beast best left in your trunk or RV. We consider portability a key factor, as it directly affects where and how you’ll use the generator.
Charging Options and Convenience
All three units offer multiple ways to recharge: AC wall outlet, solar, and DC (car). The Jackery 1000 v2 adds a smart app that lets you control charging modes, including a 1-hour emergency fast charge (which we verified in our testing, but it requires app activation). The MARBERO models keep it simple with manual buttons and a flashlight, which is a nice touch for emergencies. Consider how many USB ports and AC outlets you need; the MARBERO 237Wh has 5 USB ports and 2 AC outlets, while the Jackery has 2 USB-C and 1 USB-A, plus 3 AC ports.

Final Thoughts
In summary, the MARBERO 237Wh Solar Generator with Solar Panel is an excellent entry-level choice for weekend campers or as a small emergency backup, offering a great balance of capacity, output, and portability with a solar panel included for a reasonable price. However, if you need more power for appliances or longer outages, the Jackery Solar Generator 1000 v2 and 200W Solar is a premium investment that delivers higher capacity, faster charging, and smart features, making it ideal for home backup and RV trips. For ultra-light backpacking, the MARBERO 111Wh Solar Generator with Panels Included is a compact and affordable option that we also recommend for its portability.
Frequently Asked Questions
How long does it take to charge the MARBERO 237Wh with the included solar panel?
With the included 60W solar panel in direct sunlight, the MARBERO 237Wh can fully charge in about 5-6 hours, depending on weather and sun angle. We recommend using the panel outdoors and adjusting its angle throughout the day for optimal efficiency.
Can the MARBERO 237Wh run a mini fridge?
Yes, the MARBERO 237Wh can power a mini fridge that draws around 50-60W, but only for a few hours. For a full-day fridge use, you’d need a larger capacity like the Jackery 1000 v2, which can handle it for over 10 hours. Check our best solar generators for home backup for more options.
Is the Jackery 1000 v2 worth the extra cost compared to the MARBERO 237Wh?
If you need to power high-wattage devices or want a longer runtime, the Jackery 1000 v2 is worth the investment, especially for home backup or RV use. It offers more than four times the capacity, faster solar charging, and a longer lifespan with its LFP battery. For occasional phone charging, the MARBERO is more budget-friendly.
Can I use the MARBERO 237Wh while it’s charging via solar?
Yes, you can use the MARBERO 237Wh while it’s charging, thanks to its pass-through charging feature. This is handy when you need to keep a device powered during an outage, but note that it may slow down the charging speed.
