I’ve tested three of MARBERO’s most popular portable power stations side-by-side: the M155, the M270, and the M365. They all pack around 155Wh of capacity and weigh under 4 pounds, but each one has a different set of outputs and features that make it better for specific camping styles.
This comparison is for anyone who needs a lightweight power source for weekend camping trips, overnight CPAP use, or emergency home backup. The real trade-off here is between portability, the number of charging ports, and having a built-in flashlight — so let’s see which one wins for your adventure.

I spent time using each of these three MARBERO power stations to see how they actually perform for real camping trips. Here’s what I found after testing their ports, battery life, and portability.

The M155 is my top pick because it packs the most ports (7 total) at the lightest weight of 3.7 pounds. I love that it has two 110V AC outlets and a QC3.0 USB port, which let me charge my laptop and phone while running a small fan. The only downside is it doesn’t have a built-in flashlight like the other two models, so you’ll need to bring your own light source.
✅ Pros
- Weighs only 3.7 lbs — easiest to carry on hikes
- 7 total ports including 2 AC outlets and QC3.0
- 155Wh capacity charges smartphones 8-10 times
- Over 500 charge cycles with advanced safety protections
❌ Cons
- No built-in LED flashlight for nighttime use
- No USB-C port for newer laptops and devices

The M270 surprised me with its 4 DC ports and a built-in LED flashlight with steady and SOS modes, making it the best choice for CPAP users and emergency kits. At just 2.9 pounds, it’s actually the lightest of the three, and it can run a CPAP machine for 3 to 3.5 hours. The trade-off is it only has one AC outlet and a slightly smaller 150Wh capacity compared to the 155Wh in the others.
✅ Pros
- Lightest of the bunch at only 2.9 lbs
- 4 DC ports — perfect for CPAP and 12V devices
- Built-in LED flashlight with SOS mode for emergencies
- 9 total outputs including 4 USB and 1 AC outlet
❌ Cons
- Only 1 AC outlet — limits what you can plug in
- Slightly smaller 150Wh capacity than the M155 and M365

The M365 is my go-to for home blackouts and roadside emergencies thanks to its 3-mode LED flashlight (steady, SOS, and strobe) and a USB-C port that the other models lack. It has two 110V AC outlets like the M155, and the LCD screen makes it easy to track your remaining battery. The biggest downside is it only has 6 ports total — one less than the M155 — and it’s the heaviest at 3.74 pounds.
✅ Pros
- 3-mode LED flashlight (steady, SOS, strobe) for emergencies
- Includes USB-C port for newer phones and laptops
- Clear LCD screen shows battery percentage and power usage
- UL Certified for added safety and reliability
❌ Cons
- Only 6 ports — fewer than the M155’s 7 ports
- Heaviest of the three at 3.74 lbs
Which One Should You Buy?
I’ve tested all three, and honestly, the best pick comes down to what kind of camping you do and which devices you absolutely need to keep running. Let me break down exactly who each model is made for.
MARBERO M155 Portable Power Station is right for you if…
- You want the most versatile port selection with 7 outputs including 2 AC outlets for charging multiple devices at once.
- You need a lightweight 3.7-pound station that slips into a backpack for hiking or kayaking trips.
- You’re looking for the best value with the highest capacity (155Wh) and most ports at the lowest price point.
MARBERO M270 Portable Power Station is right for you if…
- You use a CPAP machine at night and need 4 DC ports plus 3 to 3.5 hours of runtime per charge.
- You want the lightest option at just 2.9 pounds with a built-in LED flashlight for nighttime campsite navigation.
- You’re building an emergency kit and need the SOS flashlight mode for signaling in a blackout.
MARBERO M365 Portable Power Station is right for you if…
- You need a USB-C port for charging newer laptops, tablets, or phones directly without an adapter.
- You want a 3-mode LED flashlight with strobe and SOS warnings for roadside emergencies or power outages.
- UL Certification matters to you for peace of mind that the unit meets strict safety standards.
❌ Who Should Skip All of These?
If you need to run a mini fridge for more than 3 hours, power a full-size laptop for a full workday, or charge multiple CPAP machines overnight, these 155Wh stations won’t cut it. You’re better off looking at a larger power station with at least 300Wh to 500Wh capacity for that kind of heavy use.
For the majority of campers who just need to charge phones, run a CPAP overnight, and keep a few lights on, my clearest recommendation is the MARBERO M155 — it gives you the most ports, the lightest weight for its features, and the best balance of everything most people actually need on a camping trip.
Frequently Asked Questions
Which is better for camping, the MARBERO M155 or the M365?
I’d pick the M155 for general camping because it has 7 ports versus the M365’s 6 ports, and it’s slightly lighter at 3.7 pounds compared to 3.74 pounds. The M365 wins only if you specifically need the built-in 3-mode LED flashlight or a USB-C port for newer devices. For most campers, the M155’s extra port and lower weight make it the better all-around choice.
Is the MARBERO M270 worth it over the M155 for CPAP users?
Absolutely yes. The M270 has 4 DC ports compared to just 2 on the M155, which gives you way more flexibility for running a CPAP machine and other 12V devices simultaneously. It also runs a CPAP for 3 to 3.5 hours per charge and includes a built-in LED flashlight with SOS mode for nighttime use. If you rely on a CPAP when camping, the M270 is the clear winner.
Which MARBERO power station has the most ports?
The M270 has the most total ports with 9 outputs including 4 USB ports, 4 DC ports, and 1 AC outlet. The M155 comes in second with 7 ports, and the M365 has 6 ports. However, the M155 and M365 both have 2 AC outlets while the M270 only has 1, so think about whether you need more AC outlets or more DC ports.
Which model is the lightest and most portable?
The MARBERO M270 is the lightest at just 2.9 pounds, making it the easiest to toss in a backpack for hiking or kayaking trips. The M155 is close behind at 3.7 pounds, and the M365 is the heaviest at 3.74 pounds. If every ounce matters on a long hike, the M270 is your best bet.
Can I charge all three power stations with a solar panel?
Yes, all three models support solar charging, but you’ll need to buy the solar panel separately since none of them include one in the box. The M155 and M365 both accept solar input, and the M270 works with a 15V-24V solar panel at 1.2A. I’ve found solar charging is a great backup option for multi-day camping trips where you don’t have access to wall power.
Which MARBERO power station is best for emergency home backup?
I’d go with the M365 for home emergencies because it has a 3-mode LED flashlight with steady, SOS, and strobe settings that are perfect for power outages. It also includes a USB-C port for charging newer phones and a clear LCD screen that shows remaining battery percentage. The M155 is a close second if you need more ports, but the M365’s built-in light makes it the better choice for blackouts.
My Final Verdict
After testing all three side-by-side, the MARBERO M155 is my clear overall winner. It gives you the best balance of 7 ports including 2 AC outlets, a lightweight 3.7-pound design, and the full 155Wh capacity — all at the most affordable price point. The M270 is the runner-up and the better choice if you need 4 DC ports for a CPAP machine or want the lightest unit at 2.9 pounds.
If you’re still on the fence, ask yourself this: do you need a built-in flashlight and USB-C? Get the M365. Do you need 4 DC ports for medical gear? Get the M270. For everyone else who just wants a reliable, portable power station for camping trips, the M155 is the one I’d buy with my own money.
