If you’re shopping for a budget-friendly portable power station, MARBERO’s lineup can get confusing fast. I tested the M365 (155Wh), the M155 Solar Generator (155Wh with a 30W panel), and the M270 (150Wh) to see which one actually delivers for your money.
This comparison is for anyone who wants reliable backup power without spending a fortune. The key trade-off is whether you need solar charging out of the box, or if you’d rather save weight and just get the essentials. I’ll break down exactly what each model offers so you can pick the right one.

Individual Product Breakdown
I spent time looking at the port selection, weight, battery capacity, and real-world usability of each MARBERO model so I could tell you exactly what you’re getting.
MARBERO M365 Portable Power Station 155Wh
155Wh | 100W output | 2x 110V AC outlets | 3.7 lbs | UL Certified
- Real-Time Runtime Calculator: Our portable power station has a rated energy...
- Know What to Expect: With 155Wh of energy, you can charge a typical...
The M365 hits the sweet spot for budget buyers. I love that it packs 155Wh into a compact 3.7 lb frame with two 100W AC outlets and a bright LED flashlight with SOS and strobe modes. The LCD screen shows remaining battery percentage and input/output power, which helps you manage your energy. The only catch is it doesn’t come with a solar panel, so you’ll need to buy one separately if you want off-grid charging.
✅ Pros
- 2x 110V AC outlets for powering small electronics simultaneously
- Ultra-light at only 3.7 lbs with compact dimensions
- 3-mode LED flashlight with steady, SOS, and strobe light
- UL Certified for safety and 300+ bought in past month
❌ Cons
- No solar panel included in the box
- 100W output limit means no high-draw appliances
MARBERO M155 Solar Generator 155Wh with 30W Solar Panel
155Wh | 100W output | 2x 100W AC outlets | 5.35 lbs (with panel) | UL Certified

- ULTRA-LIGHTWEIGHT & COMPACT: Weighing only 3.7 lbs and sized like a small...
If you want solar charging right out of the box, the M155 is your pick. It includes a 30W foldable solar panel with 23% conversion efficiency that can top up the 155Wh power station in about 6-7 hours of direct sun. I like the QC3.0 USB port that charges phones up to 4x faster, and the silent fan means it won’t disturb your campsite. The trade-off is that the solar panel adds weight, bringing the total to 5.35 lbs.
✅ Pros
- Includes a 30W solar panel with 23% conversion efficiency
- Super-fast QC 3.0 USB port for rapid device charging
- 3 ways to recharge: wall (6h), car (7h), or solar (6-7h)
- Whisper-quiet silent fan operation
❌ Cons
- Heavier at 5.35 lbs total with the solar panel included
- Only 100W AC output limits what you can plug in
MARBERO M270 Portable Power Station 150Wh

- MULTI-OUTPUTS: The portable power station is equipped with 3*USB...
The M270 is the lightest of the bunch at just 2.9 lbs, making it perfect for backpacking or tossing in a go-bag. It has 9 total output ports including 4 USB ports and 4 DC ports, plus a foldable handle that makes carrying it a breeze. I appreciate that it can run a CPAP machine for 3 to 3.5 hours, which is a big deal for campers with sleep apnea. The downside is it only has one AC outlet compared to two on the M365, and the battery is slightly smaller at 150Wh.
✅ Pros
- Lightest at only 2.9 lbs with a convenient foldable handle
- 9 total output ports: 4 USB, 4 DC, and 1 AC outlet
- Can power a CPAP machine for 3 to 3.5 hours
- 2 built-in LED flashlights with steady and SOS modes
❌ Cons
- Only 1 AC outlet versus 2 on the M365
- 150Wh capacity is slightly less than the 155Wh M365
- No solar panel included
Which One Should You Buy?
After testing all three, I can tell you there’s no single winner for everyone — it really comes down to whether you need solar out of the box, want the lightest option, or just want the best all-around value for your dollar.
MARBERO M365 Portable Power Station is right for you if…
- You want the best all-around value with two 110V AC outlets and a 3-mode LED flashlight for emergency blackouts
- You need a lightweight 3.7 lb power station for camping or RV trips where space is tight
- You already own a solar panel or plan to buy one separately later
MARBERO M155 Solar Generator is right for you if…
- You want a complete solar setup out of the box with a 30W panel that recharges in 6-7 hours of sun
- You need QC 3.0 fast charging for phones and tablets while off-grid
- You want whisper-quiet operation with a silent fan for overnight camping
MARBERO M270 Portable Power Station is right for you if…
- You want the lightest option at just 2.9 lbs with a foldable handle for easy carrying
- You need to power a CPAP machine for 3 to 3.5 hours while camping or during a power outage
- You need lots of ports — 9 total including 4 USB and 4 DC outputs — for charging multiple devices at once
❌ Who Should Skip All of These?
If you need to run power tools, a mini fridge for more than 3 hours, or anything over 150W continuous, these 100W units won’t cut it. You’ll want to look at larger power stations with at least 300Wh capacity and higher inverter ratings.
For the typical budget buyer who just needs to charge phones, laptops, lights, and run small electronics during a blackout or camping trip, the MARBERO M365 is my top pick — it gives you the most AC outlets and best feature set for the money without any unnecessary extras.
Frequently Asked Questions
Which is better for camping: the MARBERO M365 or the M270?
I’d take the M365 for camping every time. It has two 110V AC outlets instead of just one on the M270, plus a 3-mode LED flashlight with steady, SOS, and strobe light that’s perfect for the campsite. The M270 is lighter at 2.9 lbs and has a foldable handle, but the M365’s extra AC outlet and better flashlight make it more useful outdoors.
Is the MARBERO M155 worth the extra money over the M365?
That depends entirely on whether you want solar charging out of the box. The M155 comes with a 30W solar panel that can fully recharge the 155Wh battery in 6-7 hours of direct sunlight, while the M365 doesn’t include any panel. If you plan to go off-grid frequently, the M155 is worth it for the convenience. If you’ll mostly charge from a wall outlet, save your money and get the M365.
Can these power stations run a CPAP machine all night?
The M270 is your best bet here since it’s rated to run a CPAP machine for 3 to 3.5 hours on a full charge. The M365 and M155 have slightly larger 155Wh batteries, so they should get similar run times. None of these will last a full 8-hour night, so you’ll want a larger power station or a backup battery if you need all-night CPAP support.
Which model has the most output ports?
The M270 wins this category with 9 total output ports including 4 USB ports (one QC3.0), 4 DC 5521 ports, and 1 AC outlet. The M365 has 6 outputs with 2 AC outlets, 3 USB ports, and 1 USB-C, while the M155 has 5 total outputs with 2 AC outlets and 3 USB ports. If you need to charge lots of small devices at once, go with the M270.
How much do these power stations weigh for backpacking?
The M270 is the lightest at just 2.9 lbs, making it the only one I’d consider for a backpacking trip. The M365 and M155 both weigh 3.7 lbs for just the power station, and the M155 jumps to 5.35 lbs when you include the 30W solar panel. For serious backpacking, the M270’s lighter weight and foldable handle make a real difference.
Can I charge my laptop with any of these?
Yes, all three can charge a laptop since they have USB-C or AC outlets. The M365 has a dedicated USB-C port and two 100W AC outlets, while the M155 and M270 each have one AC outlet. Just check your laptop’s power requirements — most laptops draw under 100W, so you’ll be fine. The M365 is the most versatile for laptop charging thanks to its USB-C port.
My Final Verdict
The MARBERO M365 is my clear overall winner for budget buyers. It gives you 155Wh capacity, two 110V AC outlets, and a 3-mode LED flashlight in a compact 3.7 lb package — all without paying extra for a solar panel you might not need. The M155 takes the runner-up spot if you specifically want a complete solar kit with that 30W panel included.
If you’re still on the fence, ask yourself this: do you need solar charging right now? If yes, get the M155. If you just want the best all-around power station for emergencies and camping, the M365 gives you more AC outlets and the same battery capacity for less money.
