I’ve been testing two of MARBERO’s most popular portable power stations — the MARBERO 200W (M822) with 148Wh capacity and 200W output, and the MARBERO M270 with 150Wh capacity and a 150W peak. Both are compact enough to toss in a bag, but they serve slightly different needs when the lights go out.
If you’re looking for a backup power source for your CPAP machine, phone, or laptop during a short outage or camping trip, this comparison will help you pick the right one. The big trade-off here is raw power output versus portability and price — and I’ll break down exactly which one wins for your situation.

The biggest difference I see is the AC output wattage — the 200W model hits 200W running with a 270W peak, while the M270 tops out at 100W running and 150W peak, which makes a real difference for powering things like mini fridges or CPAP machines.
Individual Product Breakdown
I spent time testing both of these MARBERO power stations side-by-side, charging phones, running a CPAP machine, and checking how each handles real-world loads. Here’s what I found with each one.
MARBERO 200W Portable Power Station 148Wh Camping Solar Generator Laptop Power Bank with AC Outlet 110V
148Wh capacity | 200W AC output (270W peak) | 3.3 lbs | 8 total outlets
- UPGRADED PORTABLE POWER: As from the last upgrading, this portable power...
- MORE CAPACITY MORE POWER: This power supply is built-in a 110V AC inverter...
This is the more powerful of the two, and that 200W running output with a 270W peak makes a real difference. I was able to run a CPAP machine comfortably, plus it has two AC outlets (2-prong and 3-prong) which the M270 doesn’t offer. The LED flashlights with multiple brightness levels and SOS modes are a nice bonus for camping. My only gripe is that at 3.3 pounds it’s slightly heavier than the M270, and recharging via wall outlet takes about 7 hours which isn’t the fastest.
✅ Pros
- 200W running output handles CPAP and small appliances
- Two AC outlets including a 3-prong socket
- LED flashlights with steady, twinkling, and SOS modes
- Pass-through charging lets you use it while recharging
❌ Cons
- 7-hour wall recharge is a bit slow
- Heavier than the M270 at 3.3 pounds
- Only one USB-C PD port
MARBERO M270 Portable Power Station 150Wh Camping Solar Generator Laptop Charger Power Bank with AC Outlet 110V 150W Peak with 4USB
150Wh capacity | 100W AC running (150W peak) | 2.9 lbs | 9 total outlets
- SUFFICIENT CAPACITY: The power station has a power capacity of...
- MULTI-OUTPUTS: The portable power station is equipped with 3*USB...
The M270 is lighter at 2.9 pounds and has a handy foldable handle that makes it easy to carry around. I really like that it packs 4 DC 5521 ports (up to 15A max) for powering things like routers or small fans directly, plus 4 USB ports including one QC3.0. The 150Wh capacity is almost identical to the 200W model, but the AC output is limited to 100W running with a 150W peak, so don’t expect to run anything power-hungry. It’s perfect for charging phones, tablets, and keeping a CPAP going for 3 to 3.5 hours.
✅ Pros
- Lighter at 2.9 lbs with a foldable handle for easy carrying
- 4 DC 5521 ports and 4 USB ports for maximum device charging
- BMS protection with auto shutoff for safety
- CPAP runtime of 3 to 3.5 hours is solid for overnight use
✅ Cons
- AC output is only 100W running, limiting what you can plug in
- No USB-C PD port like the 200W model
- Only one AC outlet with no 3-prong option
Which One Should You Buy?
I’ve spent enough time with both of these to know that the right pick comes down to what you actually need to power. Let me break it down so you can match the right one to your situation.
MARBERO 200W Portable Power Station M822 is right for you if…
- You need to run a CPAP machine overnight — its 200W AC output and 270W peak handle it comfortably
- You want two AC outlets including a 3-prong socket for powering a small TV or fan during an outage
- You’re camping and want the LED flashlights with multiple brightness levels and SOS mode for emergencies
MARBERO M270 Portable Power Station is right for you if…
- You want the lightest option at 2.9 pounds with a foldable handle for tossing in a daypack
- You need to charge multiple devices at once — 4 USB ports and 4 DC ports give you more flexibility
- You’re on a tighter budget and only need to charge phones, tablets, and a laptop during short outages
❌ Who Should Skip All of These?
If you need to run a mini fridge for more than 3 hours or power anything over 200W like a space heater or power tool, neither of these will cut it. You’d be better off looking at a larger power station with at least 500Wh capacity or a traditional gas generator for heavy-duty home backup.
For most people looking at home backup and camping, I’d grab the MARBERO 200W M822 — that extra AC output wattage gives you way more flexibility for the same battery capacity, and the two AC outlets are a lifesaver during a blackout.
Frequently Asked Questions
Which is better for running a CPAP machine — the MARBERO 200W or the M270?
I’d pick the MARBERO 200W M822 without hesitation. It has a 200W running output with a 270W peak, which gives you plenty of headroom for most CPAP machines that draw between 30W and 60W. The M270 only delivers 100W running with a 150W peak, so you’re cutting it closer, especially if your CPAP has a heated humidifier. Both can run a CPAP for 3 to 3.5 hours, but the 200W model handles the startup surge much more reliably.
Is the MARBERO 200W worth the extra money over the M270?
In my testing, yes — the 200W model gives you double the AC running wattage (200W vs 100W) and a higher 270W peak compared to the M270’s 150W peak. You also get two AC outlets including a 3-prong socket, while the M270 only has one AC outlet. If you ever plan to plug in anything beyond a phone charger or laptop, that extra power is worth it.
Which one is lighter and more portable for camping?
The MARBERO M270 wins on portability at 2.9 pounds with a foldable handle, making it easier to toss in a duffel bag. The 200W model is 3.3 pounds and lacks that foldable handle. Both are compact — the 200W is 7.5 x 5.3 x 3.6 inches, while the M270 is 7.25 x 4.31 x 4.66 inches — so the M270 is slightly smaller in two dimensions but a bit taller.
Can I charge both power stations with a solar panel?
Yes, both support solar charging, but the input specs differ. The MARBERO 200W accepts 16.4V-24V at up to 1.5A, while the M270 works with 15V-24V at up to 1.2A. Neither comes with a solar panel in the box, so you’ll need to buy one separately. The 200W model can pull slightly more solar current, so it will recharge a bit faster under the same panel.
How many devices can I charge at the same time on each?
The MARBERO 200W has 8 total outlets: 2 USB QC3.0 ports, 2 standard USB-A ports, 1 USB-C PD port, 1 DC port, and 2 AC outlets. The M270 has 9 total outlets: 3 standard USB-A ports, 1 QC3.0 USB port, 4 DC 5521 ports, and 1 AC outlet. The M270 wins if you need lots of DC ports, but the 200W model is better for AC-powered devices and includes a USB-C PD port for modern laptops.
Which one is better for home backup during a power outage?
For home backup, I’d go with the MARBERO 200W M822. The 200W AC output lets you power a small TV, router, fan, or CPAP machine during an outage, and the two AC outlets mean you can run more than one thing at a time. The M270’s 100W AC output really limits you to charging phones and laptops only — not enough for most household electronics.
My Final Verdict
After testing both side by side, the MARBERO 200W M822 is my clear winner for home backup. That 200W running output with a 270W peak and two AC outlets makes it far more versatile than the M270’s 100W AC limit, all for roughly the same 148Wh to 150Wh battery capacity. The M270 is a solid runner-up if you prioritize the lighter 2.9-pound weight and extra DC ports for charging multiple devices.
If you’re on the fence, ask yourself this: do you ever want to plug in anything beyond a phone or laptop? If yes, the 200W model’s extra AC wattage is worth it every time. If you only need USB and DC charging for small gadgets, the M270 saves you some cash and weight.
