If you’re prepping for a home blackout, the MARBERO M270 and M365 look nearly identical on paper, but they have key differences that matter when the lights go out. Both are portable power stations around 150Wh, but the M365 packs two AC outlets instead of one and adds a USB-C port.

This comparison is for anyone looking for a lightweight emergency backup that can keep phones, a CPAP machine, or a small fan running during a power outage. I’ll break down the real trade-offs so you can decide which one fits your blackout plan better.

The M270 is a solid little workhorse at just 2.9 pounds, making it the lighter option between these two. I like that it has 4 DC ports — that’s more than the M365 — which is handy if you’re powering multiple 12V devices like a mini fridge or fan. It can run a CPAP machine for 3 to 3.5 hours, which is a big deal for campers or emergency preppers. My main gripe is the single AC outlet; during a blackout, I’d rather have two so I can plug in a lamp and charge a laptop at the same time.

✅ Pros

Very lightweight at only 2.9 lbs — easy to grab during an emergency
4 DC ports give you more 12V options than the M365
Two built-in LED flashlights with steady and SOS modes
Can charge a phone 24 times or a laptop 3 times

❌ Cons

Only one AC outlet — limits what you can plug in during a blackout
No USB-C port, which is becoming standard for modern devices

The M365 is my pick for home blackouts because it has two 110V AC outlets instead of just one, so you can power a lamp and a laptop simultaneously. It also packs a USB-C port and a total of 6 outputs, which is more versatile than the M270’s setup. It’s slightly heavier at 3.74 lbs and has a slightly larger 155Wh capacity, but that extra weight is worth it for the added ports. The built-in LCD screen showing remaining battery percentage is a smart touch I really appreciate during an outage.

✅ Pros

Two AC outlets double the plug-in options compared to the M270
Includes a USB-C port for modern phones and tablets
UL Certified for added safety assurance
LCD screen shows remaining battery, input/output power, and active ports

❌ Cons

Heavier at 3.74 lbs vs the M270’s 2.9 lbs
Only 3 DC outputs compared to the M270’s 4

Which One Should You Buy?

I’ve tested the specs on both of these, and honestly, the right pick comes down to what you’re trying to power during a blackout. Here’s how I’d match each unit to the right buyer.

MARBERO M270 Portable Power Station 150Wh is right for you if…

You need the lightest possible backup at just 2.9 lbs for carrying in a go-bag or to a campsite
You plan to power multiple 12V devices like a mini fridge and fan thanks to the 4 DC ports
You want a dedicated CPAP backup that can run for 3 to 3.5 hours and has built-in flashlights

MARBERO M365 Portable Power Station 155Wh is right for you if…

You need two AC outlets so you can plug in a lamp and a laptop at the same time during a blackout
You carry modern gadgets that charge via USB-C and want a single cable to handle them
You want UL Certification and an LCD screen that shows remaining battery percentage and active ports

❌ Who Should Skip All of These?

If you need to power a full-size refrigerator, sump pump, or any appliance over 100W, skip both of these. You’re better off looking at a larger power station with at least 500Wh capacity or a traditional gas generator for whole-home backup.

For most people dealing with a short home blackout, I’d grab the M365 because those two AC outlets and the USB-C port make it more flexible when the power goes out. It’s the better all-around emergency companion.

Frequently Asked Questions

Which is better for home blackouts, the M270 or M365?

I’d pick the M365 for home blackouts because it has two 110V AC outlets instead of just one. That means you can plug in a lamp and a laptop charger at the same time, which is way more useful when the power’s out. The M270 is fine if you only need one AC device, but the M365 gives you more flexibility.

Is the M365 worth the extra weight over the M270?

The M365 weighs 3.74 lbs compared to the M270’s 2.9 lbs, so it’s about 0.84 lbs heavier. For me, that small weight difference is absolutely worth it for the extra AC outlet and the USB-C port. Unless you’re backpacking and counting every ounce, the M365 is the better value.

Can either of these run a CPAP machine during a power outage?

Yes, both can handle a CPAP machine. The M270 claims 3 to 3.5 hours of run time, and the M365 has a slightly larger 155Wh capacity for potentially a bit more. Just keep in mind that if your CPAP has a heated humidifier, it’ll drain the battery faster — you might want to turn that feature off to stretch the run time.

Which has more ports and outlets, the M270 or M365?

The M365 wins on total outlets with 6 outputs including 2 AC outlets, 1 USB-C, 3 USB-A, and 3 DC ports. The M270 has 9 total outputs but only 1 AC outlet and no USB-C. For modern devices, the M365’s USB-C is a big advantage, though the M270 has more DC ports if you’re running 12V gear.

Can I charge these with solar panels?

Both units support solar charging. The M270 accepts 15V-24V at 1.2A, and the M365 also works with solar panels. Neither comes with a solar panel in the box, so you’ll need to buy one separately. I’d recommend at least a 60W panel to keep charging times reasonable.

Which one is more portable for emergency go-bags?

The M270 is the clear winner for portability at just 2.9 lbs with dimensions of 7.25 x 4.31 x 4.66 inches. It’s noticeably lighter than the M365 at 3.74 lbs. If you’re packing a go-bag for hurricane season or car camping, the M270 is easier to toss in and forget about until you need it.

My Final Verdict

For home blackouts, the MARBERO M365 is my clear winner. Those two AC outlets and the USB-C port make it far more practical when the power goes out, and the 155Wh capacity gives you a slight edge over the M270’s 150Wh. The M270 is still a great choice if you need the lightest possible unit at 2.9 lbs or if you’re running multiple 12V devices thanks to its 4 DC ports.

If you’re on the fence, ask yourself this: do you need to plug in more than one AC device at a time? If yes, go M365. If you’re strictly powering 12V gear or need the absolute lightest option for a go-bag, the M270 will serve you well.
