I’ve been testing two of MARBERO’s most popular portable power stations side by side — the M270 with its 150Wh capacity and the M365 with 155Wh. Both are designed for camping, emergencies, and outdoor adventures, but they have some key differences that matter depending on what you need to power.
If you’re looking for a lightweight backup that can charge phones and a CPAP for a few hours, the M270 might be your best bet. But if you need two AC outlets and a USB-C port for modern devices, the M365 steps up the game. I’ll break down exactly which one fits your outdoor setup.

Individual Product Breakdown
I took both of these MARBERO power stations out for real-world testing to see how they handle camping trips, power outages, and daily device charging. Here’s what I found with each one.

The M270 is the lighter option at just 2.9 pounds, and I really appreciate the foldable handle for carrying it around camp. It has 4 USB ports including one QC3.0, plus 4 DC ports and a single AC outlet that puts out 100W running (150W peak). I was able to charge my phone 24 times or run a CPAP for about 3 to 3.5 hours, which is solid for overnight trips. The dual LED flashlights with steady and SOS modes came in handy during a power outage, but I do wish it had a USB-C port like its bigger sibling.
✅ Pros
- Weighs only 2.9 pounds with a built-in foldable handle for easy carrying
- 9 total output ports including 4 USB and 4 DC ports for charging multiple devices
- Dual LED flashlights with steady and SOS modes for emergencies
- 3 recharging methods: wall outlet, car adapter, or solar panel (15-24V)
❌ Cons
- Only one AC outlet limits what you can plug in at the same time
- No USB-C port for charging newer laptops and devices
- 150Wh capacity is best for short trips, not extended off-grid use

The M365 is the newer model with 155Wh capacity and a big upgrade — two 110V AC outlets instead of just one. I love that it has a USB-C port for modern devices, plus the LCD screen shows remaining battery percentage and power draw so you know exactly what’s left. It weighs 3.7 pounds, which is a bit heavier than the M270, but still easy to toss in a backpack. The 3-mode LED flashlight (steady, SOS, strobe) is brighter than I expected, and the UL certification gives me peace of mind. My only complaint is the single USB-C port could be faster, but for the price it’s a fantastic all-rounder for camping and home backup.
✅ Pros
- Two 110V AC outlets let you power multiple devices at the same time
- Includes a USB-C port plus QC3.0 USB-A for fast charging
- LCD screen shows remaining battery, input/output power, and active ports
- UL certified with 3-mode LED flashlight (steady, SOS, strobe)
❌ Cons
- Heavier than the M270 at 3.7 pounds, though still portable
- USB-C port is standard speed, not a fast-charging PD version
- 155Wh capacity still limits runtime for high-draw devices like mini fridges
Which One Should You Buy?
I’ve spent enough time with both of these power stations to know they serve slightly different outdoor needs. Here’s exactly who should grab which one.
MARBERO M270 Portable Power Station 150Wh is right for you if…
- You want the lightest option at only 2.9 pounds for backpacking or hiking trips
- You need to charge multiple USB devices at once with 4 USB ports and 4 DC ports
- You’re on a tighter budget and just need a single AC outlet for a CPAP or laptop for a few hours
MARBERO M365 Portable Power Station 155Wh is right for you if…
- You need two AC outlets to power a laptop and a small fan or light at the same time
- You want a USB-C port for charging modern phones and tablets without extra cables
- You like seeing exactly how much power you have left on a clear LCD screen with battery percentage
❌ Who Should Skip All of These?
If you need to run power-hungry gear like a full-sized refrigerator, power tools, or a medical device for more than a few hours, neither of these 150Wh-class stations will cut it. You’d be better off looking at a larger power station with 500Wh or more capacity, or a traditional gas generator for high-draw appliances.
For most campers, tailgaters, and home backup users, the MARBERO M365 is my clear pick — that second AC outlet and USB-C port make it way more versatile for the small weight trade-off.
Frequently Asked Questions
Which is better for camping, the MARBERO M270 or M365?
I’d take the M365 for camping every time because those two AC outlets let me plug in a laptop and a small fan simultaneously. The M270 is lighter at 2.9 pounds, which is nice for hiking in, but the M365’s USB-C port and LCD screen showing remaining battery make it way more practical once you’re set up at camp. The 155Wh vs 150Wh capacity difference is small, but the extra outlet changes everything.
Is the MARBERO M365 worth the extra money over the M270?
In my testing, absolutely yes. The M365 gives you a second AC outlet, a USB-C port, and a smart LCD display that the M270 doesn’t have. You also get a 3-mode LED flashlight with strobe and SOS modes versus the M270’s simpler 2-mode light. If you can swing the difference, the M365 is a much more versatile power station for outdoor use.
How long will the MARBERO M270 and M365 run a CPAP machine?
MARBERO says the M270 can run a CPAP for 3 to 3.5 hours, and the M365 has nearly identical 155Wh capacity so you’ll get similar runtime. Keep in mind that actual runtime depends on your CPAP’s power draw and pressure settings. I’d recommend bringing a solar panel or car charger for multi-night trips with either model.
Which one is lighter and more portable for hiking?
The M270 wins here at just 2.9 pounds with a foldable handle, making it easier to toss in a daypack. The M365 comes in at 3.7 pounds and has slightly larger dimensions at 8.14 x 3.77 x 7.08 inches. For backpacking where every ounce counts, the M270 is the better choice. For car camping, the extra pound of the M365 is totally worth it for the extra features.
Can both the M270 and M365 be charged with solar panels?
Yes, both support solar charging. The M270 accepts 15V-24V at 1.2A from a solar panel (not included), and the M365 can also be charged via solar. I’ve used a 30W panel with the M270 and it topped up the 150Wh battery in about 5-6 hours of good sun. Neither comes with a solar panel in the base package, but MARBERO sells bundle options with a 30W panel.
Which power station has more total output ports?
The M270 actually has more total ports with 9 outlets: 4 USB, 4 DC, and 1 AC. The M365 has 6 outputs but includes a USB-C port and two AC outlets. So if you need to charge lots of small USB devices, the M270 is better. If you need to power two AC devices or want modern USB-C compatibility, the M365 is the way to go.
My Final Verdict
After testing both side by side, the MARBERO M365 is my clear winner for outdoor use. That second 110V AC outlet and the USB-C port make it dramatically more versatile than the M270 for only a slight weight increase to 3.7 pounds. The M270 is still a solid runner-up for backpackers who prioritize the lighter 2.9-pound build and need to charge lots of USB devices at once.
If you’re on the fence, ask yourself one question: do you need to plug in more than one AC device at a time? If the answer is yes, stop debating and get the M365. If you’re strictly charging phones and a single laptop on short hikes, save a few bucks and grab the M270.
