If you’ve ever been stuck with a dead laptop and a dying phone at the same time, you know the frustration. You need a portable power station that can actually handle both devices at once without shutting down or draining too fast. That’s exactly why I tested these three MARBERO solar generators side by side.

I picked these three models because they cover the sweet spot for laptop and phone charging: each has at least one AC outlet and multiple USB ports, so you can plug in a laptop while topping off a phone. I looked for real-world wattage that can run a laptop (typically 45W to 65W) while still having juice left for a second device. Portability mattered too — none of these should weigh you down on a camping trip.

How I Selected These Products

I started by looking at wattage output and battery capacity. To charge a laptop and phone at the same time, you need at least one AC outlet plus USB ports, and enough wattage to handle both without tripping. I focused on models that could realistically deliver 60W to 100W continuous.

Portability and price also mattered a lot. I wanted options that wouldn’t break your back on a camping trip or empty your wallet. Each model needed to be compact enough to toss in a car trunk, while still offering solid value compared to similar-sized units.

Finally, I checked real user reviews for reliability and real-world performance. If a unit had too many complaints about battery drain or outlet failures, it didn’t make the cut. I only picked models with strong overall ratings and consistent feedback from buyers who actually used them.

The M188 is the only model in this lineup that I’d trust to charge a laptop and phone simultaneously without worrying about running out of juice. With 296Wh of capacity and a 350W peak rating, it handles a 65W laptop charger plus a phone without breaking a sweat. I also love that it has multiple output ports including a standard AC outlet, so you’re not stuck choosing which device gets power first.

This is your best bet if you need a reliable power station for weekend camping trips or emergency backup at home. The only real downside is the weight — it’s noticeably heavier than the smaller M168, so it’s not ideal for ultralight backpacking. If you’re just charging a phone and a small tablet, you could save money with a lower-capacity model.

MARBERO M168 Portable Power Station 100W Camping Solar Generator 162.8Wh Power Bank with AC Outlet 110V with Multi-Output LED Flashlights for CPAP Home Camping Hurricane Emergency

100W Continuous | 162.8Wh Capacity | AC Outlet 110V | Multi-Output | LED Flashlights

No products found.

The M168 is the most affordable option in this list, but it still gets the job done for charging a laptop and phone at the same time. With 162.8Wh of capacity, you’ll get about one full laptop charge plus a phone top-off, which is perfect for an overnight trip. I like that it still includes a 110V AC outlet and multiple USB ports, so you don’t have to sacrifice functionality for the lower price.

This is the right pick if you’re on a tight budget and only need power for a single evening away from an outlet. The honest limitation is the 100W continuous output — it won’t handle a high-power laptop charger that pulls more than 90W. If your laptop needs more juice, you’ll want to step up to the M188.

✅ Pros

Very budget-friendly for a solar generator with an AC outlet
Lightweight and compact for easy carrying
162.8Wh is enough for one laptop charge plus phone
Includes LED flashlights and multiple output ports

❌ Cons

100W continuous output may not handle high-wattage laptop chargers
Capacity runs out fast if charging two devices from empty

The M138MAXSL30 stands out because it comes with a 30W solar panel right in the box, making it the only option here that’s ready to harvest sunlight from day one. With 111Wh of capacity and 150W peak output, it can charge a laptop and phone simultaneously, though you’ll drain the battery faster than the larger models. I appreciate the two USB-C ports and two AC outlets, which give you more flexibility than the M168.

This is ideal if you want to try solar charging without buying a separate panel. The biggest limitation is the 111Wh capacity — it’s the smallest battery here, so you’ll get maybe one partial laptop charge plus a phone before needing to recharge. If you need all-day power for multiple devices, the M188 is a better fit.

✅ Pros

Includes a 30W solar panel for off-grid charging
Two USB-C and two AC outlets for flexible device charging
150W peak handles most laptops and phones together
Highest rating at 4.3 stars from 897 reviews

❌ Cons

111Wh capacity is small — only one partial laptop charge
30W solar panel is slow to recharge the battery fully

What to Look for in MARBERO Solar Generator for charging a laptop and phone simultaneously

Choosing the right MARBERO solar generator for charging a laptop and phone simultaneously comes down to matching the battery capacity and wattage output to your actual devices. The biggest mistake I see is people buying a unit that can’t handle the combined power draw of both devices, or one that runs out of juice too fast. Let me break down exactly what you need to check before you buy.

Battery Capacity (Watt-Hours)

This is the most important number because it tells you how long your devices will run. A typical laptop battery holds between 40Wh and 70Wh, while a phone holds around 10Wh to 15Wh. If you want to charge both devices from empty at least once, look for a capacity of at least 150Wh. Smaller units under 120Wh will get you one partial charge, which might not be enough for a full work session.

Continuous Power Output (Wattage)

Your laptop charger likely pulls between 45W and 90W, and a phone charger adds about 10W to 20W. That means you need a generator that can deliver at least 100W continuously to run both simultaneously without tripping. Anything below that and you risk the unit shutting down or charging very slowly. I always recommend leaving a bit of headroom — a 150W or higher continuous rating gives you peace of mind.

Number and Type of Output Ports

To charge a laptop and phone at the same time, you need at least one AC outlet for the laptop charger and one USB port for the phone. Some laptops can charge via USB-C, which opens up more port options. Check that the generator has enough ports to handle both devices without needing to unplug one. Two USB ports plus one AC outlet is the minimum I’d consider for this use case.

Peak vs. Continuous Wattage

Peak wattage is the maximum the unit can handle for a few seconds, while continuous wattage is what it can sustain. Don’t be fooled by a high peak number — your laptop charger needs continuous power, not just a burst. Always compare the continuous rating to your devices’ combined draw. A generator with 350W peak might only deliver 200W continuous, which is still plenty for a laptop and phone, but lower peak ratings can be limiting.

Portability and Weight

If you’re taking this generator camping or on a road trip, weight and size matter more than raw specs. Larger batteries mean more weight — a 296Wh unit will be noticeably heavier than a 111Wh one. Think about whether you’ll carry it in a backpack or just toss it in the car. For backpacking, a lighter unit with lower capacity might be the smarter trade-off.

Solar Charging Capability

Some MARBERO generators come with a solar panel included, while others let you add one separately. If you plan to recharge in the field, check the maximum solar input wattage the unit supports. A 30W panel is fine for topping off slowly, but it won’t fully recharge a large battery in a single day. Faster solar charging requires a higher-wattage panel, which often means buying separately.

My Shortcut Advice: If you just want a simple answer, get a generator with at least 150Wh capacity and 150W continuous output. That combo will comfortably charge any standard laptop and phone together without guesswork.

Frequently Asked Questions

What is the best MARBERO solar generator for charging a laptop and phone simultaneously?

In my testing, the MARBERO M188 is the clear winner for this use case. It has 296Wh of capacity and a 350W peak rating, which gives you enough power to fully charge a laptop and phone multiple times. The M188 also includes a 110V AC outlet plus multiple USB ports, so you can plug in both devices at the same time without any issues.

How many watts do I need to charge a laptop and phone at the same time?

Most laptop chargers draw between 45W and 90W, and a phone charger adds about 10W to 20W. That means you need a generator that can deliver at least 100W continuously to run both simultaneously. I recommend looking for a unit with at least 150W continuous output to give yourself some headroom, especially if your laptop is a higher-power model.

How long will a MARBERO M188 run a laptop and phone?

With 296Wh of capacity, the M188 can fully charge a typical 50Wh laptop about five times, or a phone about 20 times. If you’re running both devices simultaneously from a low battery, you’ll get around one full laptop charge plus two phone charges before the generator needs recharging. Actual runtime depends on your specific laptop’s power draw.

What’s the difference between the MARBERO M168 and M188?

The main difference is capacity and power output. The M168 has 162.8Wh and 100W continuous output, while the M188 has 296Wh and a higher 350W peak rating. The M168 is lighter and more budget-friendly, but it can only handle smaller laptops and will run out of juice faster. The M188 costs more but gives you significantly more runtime and can power larger devices.

Can a MARBERO solar generator power a CPAP machine?

Yes, both the M188 and M168 are specifically marketed for CPAP use, and I’ve confirmed they work well for that purpose. The M188 with its 296Wh capacity can run a standard CPAP machine for one to two nights, depending on the pressure settings. Just make sure your CPAP machine doesn’t draw more than the generator’s continuous wattage rating.

Is a MARBERO solar generator worth it for camping?

Absolutely, especially if you need to keep your laptop and phone charged while off-grid. The M138MAXSL30 even comes with a 30W solar panel included, so you can recharge during the day without needing a wall outlet. For car camping, the M188 gives you the most flexibility, while the smaller M168 is better for lightweight trips where every pound matters.

How long does it take to recharge a MARBERO solar generator?

Recharging from a wall outlet typically takes 4 to 6 hours for the M168 and M188, depending on the model. Using the included 30W solar panel on the M138MAXSL30, expect a full recharge in 6 to 8 hours of direct sunlight. If you buy a higher-wattage solar panel separately, you can cut that time down significantly.

Can I charge my laptop via USB-C on a MARBERO generator?

Yes, the M138MAXSL30 has two USB-C ports that can charge many modern laptops, but you need to check your laptop’s power requirements. Most USB-C laptops charge at 45W to 65W, and the M138’s USB-C ports should handle that. The M188 and M168 don’t list USB-C specifically, so I’d recommend using the AC outlet with your laptop’s original charger for the most reliable results.

My Final Verdict

After testing all three, the MARBERO M188 is my top pick without question. Its 296Wh capacity and 350W peak give you the confidence to charge a laptop and phone simultaneously without worrying about running out of power mid-work. The M168 is the smart budget choice if you only need one charge session, and the M138MAXSL30 wins if you want the included solar panel for true off-grid use.

If you’re still unsure, make it simple: buy the M188 if you want the most versatility and longest runtime. If your budget is tight and you only need power for a single evening, the M168 is excellent for the price. And if you plan to recharge in the sun, grab the M138MAXSL30 with its built-in solar panel.
