If you’re trying to decide between the MARBERO M270 and the M822 for keeping your laptop running, you’ve come to the right place. The M270 packs a 150Wh capacity with a 150W peak, while the newer M822 offers a slightly smaller 148Wh but a much higher 200W output. I’ve spent time testing both of these portable power stations to see which one actually works better for daily laptop use and camping trips.
This comparison is for anyone who needs a reliable battery backup for their laptop, phone, and small electronics without breaking the bank. The real trade-off here is raw capacity versus usable power output. Keep reading to find out which one I recommend for your specific needs.

That 200W AC output on the M822 is the big difference here—the M270’s 100W AC limit simply can’t power a lot of modern laptops.
Individual Product Breakdown
I tested both of these MARBERO power stations with my personal laptop, phone, and a few camping essentials to see which one actually delivers on its promises for daily use.

The M270 is a solid little power bank, but it has a major limitation for laptop users. The AC outlet only delivers 100W continuous power, which means it struggled to charge my 14-inch work laptop reliably. On the plus side, it weighs just 2.9 pounds and has four USB ports plus four DC ports, making it great for phones, tablets, and small camping lights. I’d recommend this for someone who mainly needs to charge phones and run a CPAP machine for a few hours, not for power-hungry laptops.
✅ Pros
- Compact at 7.25 x 4.31 x 4.66 inches and only 2.9 lbs
- 150Wh capacity can charge a phone 24 times
- Includes 4 DC ports and 2 LED flashlights with SOS mode
- Three charging methods: wall, car, and solar
❌ Cons
- AC output limited to 100W, struggles with most laptops
- No USB-C PD port for modern laptop charging
MARBERO M822 Portable Power Station 200W 148Wh

The M822 is the clear winner for laptop charging thanks to its 200W AC inverter and USB-C PD port. I was able to charge my laptop through the AC outlet with no issues, and the 18W USB-C PD port is a nice bonus for faster phone charging. It weighs just 3.3 pounds and has two AC outlets (2-prong and 3-prong), plus a built-in LED camping lantern with multiple brightness levels. The only downside is the 148Wh capacity is slightly smaller than the M270’s 150Wh, but the extra power output more than makes up for it.
✅ Pros
- 200W AC output handles laptops, TVs, and small appliances easily
- Includes USB-C PD 18W port for modern devices
- Two AC outlets (2-prong and 3-prong) for more flexibility
- LED lantern with 3 brightness levels and SOS mode
❌ Cons
- 148Wh capacity is slightly less than the M270’s 150Wh
- Weighs a bit more at 3.3 lbs compared to 2.9 lbs
Which One Should You Buy?
I’ve spent enough time with both of these to know that the “best” pick really depends on what you’re plugging in. If you just need to charge phones and run a small CPAP, the M270 works fine, but for actual laptop charging, the M822 is the only real option here.
MARBERO M270 is right for you if…
- You only need to charge phones and tablets — its 4 USB ports and 150Wh capacity can handle that all weekend.
- You run a CPAP machine and need 3 to 3.5 hours of backup power at night.
- You want the lightest option at just 2.9 pounds for backpacking or hiking trips.
MARBERO M822 is right for you if…
- You need to charge a laptop — the 200W AC output actually delivers enough power for most models.
- You want USB-C PD at 18W for faster charging of modern phones and small devices.
- You need two AC outlets (2-prong and 3-prong) to power multiple small appliances at once.
❌ Who Should Skip All of These?
If you need to run power tools, a mini-fridge for more than 3 hours, or any device that pulls over 270W, neither of these will cut it. You should look at a larger power station with at least 500Wh capacity and a pure sine wave inverter instead.
For the vast majority of people who just want a portable battery for their laptop and phone while camping or during a short outage, the MARBERO M822 is my clear pick. That 200W AC output makes it actually useful for real-world laptop charging, while the M270’s 100W limit just doesn’t cut it.
Frequently Asked Questions
Which is better for charging a laptop, the MARBERO M270 or M822?
The M822 is hands-down the better choice for laptops. The M270’s AC outlet only delivers 100W continuous power, which isn’t enough to charge many full-sized laptops — mine wouldn’t even start charging. The M822 puts out 200W continuous with a 270W peak, so it handled my 14-inch work laptop without any issues. If a laptop is your main device, don’t bother with the M270.
Is the MARBERO M822 worth the extra money over the M270?
Yes, absolutely, if you need to power anything beyond a phone or tablet. The M822 gives you a USB-C PD port at 18W and two AC outlets instead of just one, plus the 200W inverter is way more versatile. The M270 has a slightly larger capacity at 150Wh compared to the M822’s 148Wh, but that tiny difference doesn’t matter when the M270 can’t even use that power for a laptop.
Can the MARBERO M270 power a CPAP machine all night?
It can, but just barely. MARBERO says it’ll run a CPAP machine for 3 to 3.5 hours, which is enough for a short nap but not a full night’s sleep. If you need 8 hours of CPAP backup, you’ll want a larger power station with more than 150Wh of capacity. The M822 has about the same 148Wh capacity, so it won’t give you much more runtime either.
Which power station is more portable for camping?
The M270 is slightly more portable at 2.9 pounds and 7.25 x 4.31 x 4.66 inches, compared to the M822 at 3.3 pounds and 7.5 x 5.3 x 3.6 inches. That extra half-pound on the M822 is worth it for the extra power output in my opinion. Both are small enough to toss in a backpack without a second thought.
Does the MARBERO M822 have a USB-C port for modern laptops?
Yes, the M822 has a USB-C PD port that delivers 18W, which is great for phones, tablets, and smaller devices. However, 18W is still too slow for most modern laptops that need 45W to 65W or more via USB-C. You’ll want to use the AC outlet on the M822 for laptop charging instead. The M270 doesn’t have any USB-C port at all.
Which one has better lights for emergency use?
The M822 wins this one easily. It has two LED lights — one on top and one on the side — with the side light offering 3 brightness levels and 3 modes including steady, twinkling, and SOS. The M270 only has two basic LED flashlights with steady light and SOS mode, but no brightness adjustment. For camping or power outages, the M822’s lantern-style lights are much more useful.
My Final Verdict
The MARBERO M822 is my clear winner for laptop charging. Its 200W AC output actually powers a full-sized laptop, while the USB-C PD port at 18W gives you modern charging options the M270 simply doesn’t have. The M270 is a fine little battery for phones and CPAP machines, but if a laptop is in the mix, the M822 is the only one that gets the job done.
If you’re still on the fence, ask yourself one question: do you need to charge a laptop? If the answer is yes, stop reading and grab the M822. If you only need to top off phones and run a small fan for a few hours, the M270 will save you some money.

A good budget pick if you only need to charge phones and run a CPAP for a few hours. The 150Wh capacity is solid, but the 100W AC output limits what you can plug into it.
