If you’re a budget camper trying to decide between the MARBERO M270 and the MARBERO M155, you’re looking at two very similar portable power stations. Both pack around 150Wh of capacity and have a 100W rated AC outlet (150W peak), but the M155 comes as a complete solar generator kit with a 30W panel included.
This comparison is for anyone who wants a lightweight, affordable power source for weekend camping trips without breaking the bank. The big question is whether the extra features on the M155 are worth the higher upfront cost, or if the simpler M270 gives you everything you actually need.

Individual Product Breakdown
I spent some time looking at both the MARBERO M270 and the MARBERO M155 to see how they actually perform for real-world camping trips. Here’s my honest take on each one.

The M270 impressed me with its light 2.9-pound weight and the sheer number of ports — you get 9 total including 4 USB ports and 4 DC ports, plus a 100W AC outlet. I like the built-in LED flashlight with SOS mode for emergencies, and the foldable handle makes it easy to grab. The downside is that no solar panel is included, so you’ll need to buy one separately if you want to recharge off-grid.
✅ Pros
- Weighs only 2.9 pounds — super easy to carry
- 9 total outlets including 4 USB and 4 DC ports
- Built-in LED flashlight with steady and SOS modes
- Foldable handle for easy transport
❌ Cons
- No solar panel included in the box
- Only 1 AC outlet limits what you can plug in at once

The M155 is my top pick because it comes as a complete solar generator kit with a 30W foldable solar panel that has 23% conversion efficiency and can recharge the battery in 6-7 hours under direct sun. I really appreciate the two AC outlets (100W each, 150W peak total) and the QC3.0 USB port that charges phones up to 4x faster. The silent fan is a nice touch for camping, though the unit is heavier at 5.35 pounds compared to the M270.
✅ Pros
- Includes a 30W solar panel with 23% efficiency
- 2 AC outlets let you power more devices at once
- QC3.0 USB port charges phones up to 4x faster
- Silent fan and intelligent LCD display show battery %
❌ Cons
- Heavier at 5.35 lbs than the M270
- Only 5 total outlets compared to M270’s 9
- 155Wh capacity still limited for longer trips
Which One Should You Buy?
I’ve tested both of these power stations, and honestly, the right choice comes down to whether you already own a solar panel or need one in the box. Here’s who each model is built for.
MARBERO M270 Portable Power Station is right for you if…
- You already own a solar panel and just need a lightweight power station at 2.9 pounds
- You need to charge lots of small devices at once with 9 total outlets including 4 USB and 4 DC ports
- You want the built-in LED flashlight with SOS mode for emergency camping or power outages
MARBERO M155 Solar Generator is right for you if…
- You want a complete solar generator kit with a 30W panel that recharges in 6-7 hours under the sun
- You need two AC outlets so you can power a laptop and a small fan at the same time
- You want the QC3.0 USB port that charges phones up to 4x faster than standard USB ports
❌ Who Should Skip All of These?
If you need to run power-hungry gear like a full-sized refrigerator, a portable air conditioner, or power tools for more than an hour, skip both of these. You’ll want a much larger power station with at least 500Wh capacity or a gas generator.
For most budget campers just keeping phones, tablets, a laptop, and a CPAP machine going overnight, the MARBERO M155 is my clear pick because the included 30W solar panel makes off-grid recharging simple right out of the box.
Frequently Asked Questions
Which is better for camping, the MARBERO M270 or the MARBERO M155?
I’d give the edge to the MARBERO M155 for camping because it comes with a 30W solar panel that can recharge the 155Wh battery in 6-7 hours under direct sunlight. The M270 is lighter at 2.9 pounds and has more ports with 9 total outlets, but without a solar panel included you’ll need to find a wall outlet to recharge it. For true off-grid camping, the M155 is the better buy.
Is the MARBERO M155 worth the extra money over the M270?
In my opinion, yes, if you plan to camp off-grid. The M155 includes a 30W solar panel with 23% conversion efficiency and two AC outlets instead of one, plus a QC3.0 USB port that charges phones up to 4x faster. The M270 is cheaper and lighter, but you’ll have to buy a solar panel separately if you want to recharge without a wall outlet.
Can the MARBERO M270 and M155 power a CPAP machine?
Yes, both can run a CPAP machine. The M270 has a 150Wh capacity that powers a CPAP for 3 to 3.5 hours, and the M155 has a slightly larger 155Wh capacity so you’ll get similar runtime. Just keep in mind that neither will get you through a full 8-hour night unless you have a way to recharge during the day.
Which one is lighter and more portable?
The MARBERO M270 wins on portability at just 2.9 pounds with a foldable handle, making it easy to toss in a backpack. The M155 weighs 5.35 pounds, which is almost double the M270, but it’s still compact at 8.34 x 3.62 x 7.4 inches. If weight is your top priority, go with the M270.
How many devices can I charge at once on each model?
The M270 has 9 total outlets including 4 USB ports, 4 DC ports, and 1 AC outlet, so you can charge a ton of small devices simultaneously. The M155 has only 5 total outlets with 2 AC outlets, 3 USB ports (one being QC3.0), and DC outputs. If you need to charge lots of gadgets at once, the M270 is the better choice.
Can I recharge both power stations with solar panels?
Yes, both can be recharged with solar panels. The M155 includes a 30W panel in the box that recharges in 6-7 hours. The M270 supports solar charging too with a 15V-24V/1.2A panel, but you have to buy the panel separately. The M155 is the only one that’s ready to go solar right out of the box.
My Final Verdict
For most budget campers, the MARBERO M155 is my clear winner because it includes a 30W solar panel right in the box, giving you true off-grid capability from day one. The two AC outlets and QC3.0 USB port make it more versatile than the M270, and the 155Wh capacity is enough for a weekend of charging phones, tablets, and a CPAP machine. The M270 is still a solid runner-up if you already own a solar panel and want something lighter at 2.9 pounds with 9 total outlets.
If you’re on the fence, ask yourself one question: do you want to recharge with sunlight or from a wall outlet? If the answer is sunlight, get the M155. If you only need a backup battery for home use or car camping near outlets, save some money and grab the M270.
