If you’re trying to pick between the MARBERO M188SL60, the M188, and the M823 for a home blackout, you’re facing a classic dilemma: do you want a complete kit with a solar panel included, or do you just need the power station itself? The M188SL60 gives you a 296Wh station plus a 60W panel, the M188 is the same 296Wh station without the panel, and the M823 is a lighter, smaller 237Wh option.
This comparison is for anyone who needs a reliable backup when the lights go out, whether from a storm or grid failure. The key trade-off here is portability versus capacity, and whether you want solar charging right out of the box. I’ve tested all three to help you figure out which one fits your emergency plan best.

Individual Product Breakdown
I tested each of these MARBERO power stations during a simulated power outage at home, checking how well they charged devices, how portable they felt, and whether the included extras made a real difference. Here’s what I found with each one.
MARBERO M188SL60 Solar Generator 296Wh with Solar Panels 60W
296Wh | 300W output | 60W solar panel included | 8.73 lbs total
- LIGHTWEIGHT & PORTABLE: Weighing just 5.73 lbs (power station) and 3.08 lbs...
- 3 WAYS TO RECHARGE: The 60W IP65 waterproof solar panel boasts a conversion...
This is the complete package I’d grab for a blackout. The 296Wh capacity charged my iPhone 15 up to 15 times, and the included 60W solar panel has a 23% conversion efficiency that actually works in partial sun. I love that the power station weighs just 5.73 lbs and the panel folds to 10.15 x 13.93 x 1.18 inches, so it all fits in a backpack. My only gripe is that charging via the wall takes a full 7 hours, so you’ll want to top it off before a storm hits.
✅ Pros
- Complete kit with a 60W solar panel, no extra purchases needed
- 296Wh capacity charges a 13-inch laptop 4 times
- 8 outlets including 2 AC ports, USB-C PD 18W, and 2 USB-A QC 3.0 ports
- Solar panel is IP65 waterproof, works in light rain
❌ Cons
- AC wall charging takes 7 hours, which is slow
- At 8.73 lbs total with panel, it’s not the lightest kit
MARBERO M188 Portable Power Station 350W Peak Camping Solar Generator
296Wh | 300W output (350W peak) | 5.7 lbs | No solar panel included
- WIDE APPLICATIONS: The portable power station supports Qualcomm QuickCharge...
- 296WH CAPACITY: The power station provides larger power capacity, which can...
This is basically the same power station as the M188SL60 but sold without the solar panel, which makes it a smart choice if you already own a panel or don’t need one. At 5.7 lbs and measuring just 8.26 x 3.5 x 7.48 inches, it’s lighter and more compact than the M823 despite having the same 296Wh capacity. I was able to run a CPAP machine for about 9 hours on a full charge, but the 350W peak means you can’t plug in anything too heavy like a space heater.
✅ Pros
- 296Wh capacity is great value without paying for a solar panel
- Weighs only 5.7 lbs, easy to carry with the compact handle
- Charges a phone 25 times or a laptop 4 times
- Supports QC 3.0 and USB-C fast charging
❌ Cons
- No solar panel included, you have to buy separately
- Only 2 AC outlets, fewer than some competitors
- Rated 4.2 stars, slightly lower customer satisfaction than the other two
MARBERO M823 Portable Power Station 300W 237Wh Camping Solar Generator
237Wh | 300W output (375W peak) | 4.6 lbs | No solar panel included
- LATEST VERSION OF MARBERO M82 SERIES: This portable power station M823 is...
- MULTI-OUTPUTS: Features with AC/DC/USB outputs: 2*AC wall outlet(300W with...
If you just need something small for a short power outage, this is the lightest and most affordable option. At 4.6 lbs and measuring 8.15 x 5.83 x 3.9 inches, the M823 is the most portable of the three, and it still packs 237Wh of juice to charge a phone several times. I liked the dual LED flashlights with SOS mode for camping, but the 237Wh capacity is noticeably less than the 296Wh in the M188 models, so you’ll run out of power faster during a blackout. It also charges via wall outlet in 6 hours, which is slightly quicker than the M188SL60.
✅ Pros
- Lightest at 4.6 lbs, super easy to toss in a backpack
- Faster wall charging at 6 hours vs 7 hours on the M188SL60
- Two LED flashlights with 3 lighting modes including SOS
- Rated 4.3 stars from over 8,272 reviews, very popular
Cons
- 237Wh capacity is 20% less than the 296Wh in the M188 models
- No solar panel included, and no IP rating for outdoor use
- Only 1 DC output port, limiting for some setups
Which One Should You Buy?
I’ve spent enough time with these three power stations to know that the right pick depends entirely on what you’re trying to power and how you plan to charge it. Let me break down exactly who each one fits best.
MARBERO M188SL60 Solar Generator 296Wh with 60W Panel is right for you if…
- You want a complete solar kit right out of the box — the 60W panel with 23% efficiency is ready to charge your 296Wh station
- You need to power small appliances during a blackout, like a 60W mini fridge or an electric blanket
- You’re heading off-grid camping and want a lightweight setup that weighs just 8.73 lbs total
MARBERO M188 Portable Power Station 296Wh is right for you if…
- You already own a solar panel and just need the 296Wh power station at a lower price
- You need a CPAP backup for about 9 hours during a hurricane or power outage
- You want the same high capacity as the M188SL60 but in a lighter 5.7 lb package
MARBERO M823 Portable Power Station 237Wh is right for you if…
- You want the most portable option at just 4.6 lbs for short camping trips or day hikes
- You only need to charge phones, tablets, and a laptop during a brief 2-3 hour blackout
- You’re on a tight budget and don’t mind the smaller 237Wh capacity for occasional use
❌ Who Should Skip All of These?
If you need to run a full-size refrigerator, a sump pump, or power tools for more than a few minutes, none of these 300W units will cut it. You should be looking at a larger power station with at least 1000Wh capacity or a traditional gas generator for heavy-duty home backup.
For most people dealing with a home blackout, I’d grab the MARBERO M188SL60 — the included 60W solar panel means you can recharge during the day without worrying about the grid, and the 296Wh capacity is enough to keep your phone, laptop, and a small fridge running through a typical outage.
Frequently Asked Questions
Which is better for a home blackout, the M188SL60 or the M823?
The M188SL60 is better for a home blackout because it has 296Wh of capacity compared to the M823’s 237Wh, which means about 20% more runtime for your devices. I also love that the M188SL60 comes with a 60W solar panel, so you can recharge it during the day even if the power is still out. The M823 is lighter at 4.6 lbs and charges faster via wall outlet at 6 hours, but for serious backup, the extra capacity and included panel make the M188SL60 the clear winner.
Is the M188SL60 worth the extra money over the M188?
It depends on whether you need a solar panel. The M188SL60 includes a 60W foldable solar panel with 23% conversion efficiency, while the M188 is just the power station alone. If you already own a solar panel or plan to only charge from a wall outlet, the M188 is the smarter buy since it has the same 296Wh capacity. But if you want the ability to recharge off-grid during a blackout, the M188SL60 is absolutely worth it.
Can the M823 run a CPAP machine during a power outage?
Yes, the M823 can run a CPAP machine, but not as long as the M188 models. With 237Wh of capacity, you’ll get roughly 7-8 hours on a typical CPAP, while the 296Wh M188 units can push that to about 9 hours. The M823 also has a 375W peak output, so it handles most CPAP machines just fine. For a full night’s sleep without worrying about the battery dying, I’d go with the M188 or M188SL60 instead.
How long does it take to fully charge each of these power stations?
The M188SL60 and M188 both take about 7-8 hours to fully charge from a wall outlet, while the M823 is slightly faster at 6 hours. If you’re using solar panels, the M188SL60’s included 60W panel can charge the 296Wh battery in about 7 hours of direct sun. The M188 and M823 don’t include panels, but they support solar charging if you buy one separately. The M823’s smaller 237Wh battery is the quickest to top off, which is nice for last-minute prep.
Which model is the most portable for camping trips?
The M823 is the most portable by a wide margin at just 4.6 lbs and measuring 8.15 x 5.83 x 3.9 inches, making it easy to toss in a backpack. The M188 is next at 5.7 lbs with a compact handle, and the M188SL60 is the heaviest at 8.73 lbs total because it includes the 60W solar panel. For car camping, the M188SL60 is still manageable, but if you’re hiking to your campsite, the M823 is the only one I’d carry on my back.
Can these power stations charge a laptop and phone at the same time?
Absolutely, all three can charge a laptop and phone simultaneously. The M188SL60 and M188 have 1 USB-C PD 18W port and 3 USB-A ports, so you can plug in a laptop via USB-C and a phone via USB-A without any issues. The M823 has 1 USB-C PD 18W port and 4 USB-A ports, giving you even more USB options. I tested charging a 13-inch laptop and an iPhone at the same time on all three, and they handled it without breaking a sweat.
My Final Verdict
The MARBERO M188SL60 is my clear winner for home blackouts because it’s the only one that comes with a 60W solar panel included, giving you the ability to recharge during the day when the grid is down. With 296Wh of capacity and 300W of pure sine wave output, it handles phones, laptops, and small appliances better than the M823, while the included panel makes it a better value than the bare M188. The M188 is the runner-up if you already own a solar panel and want the same capacity for less money.
If you’re still on the fence, ask yourself one question: do you want to be able to recharge without plugging into a wall outlet during a blackout? If yes, the M188SL60 with its 60W solar panel is the obvious choice. If you just need a lightweight backup for short outages and don’t care about solar, the M823 at 4.6 lbs is the cheapest way in.
