Individual Product Breakdown
I took each of these MARBERO power stations for a test run to see how they actually perform during a blackout. Here is my honest take on each one.
MARBERO M270 Portable Power Station 150Wh

The M270 is the smallest and lightest of the three at just 2.9 pounds, making it the easiest to toss in a bag for a short outage. I like that it has 4 USB ports and 4 DC ports for charging multiple phones or a tablet at once, but the 150Wh capacity only runs a CPAP machine for about 3 to 3.5 hours. This is a solid pick if you just need to keep phones and a laptop alive during a brief blackout, but don’t expect it to power a mini fridge for long.
✅ Pros
- Extremely portable at only 2.9 pounds
- 9 total output ports including 4 USB and 4 DC
- Built-in LED flashlight with steady and SOS modes
❌ Cons
- Only 150Wh capacity limits runtime for larger devices
- AC outlet limited to 100W continuous with 150W peak
MARBERO M365 Portable Power Station 155Wh
155Wh | 100W Output | 2 AC Outlets | 3.74 lbs

The M365 is a nice upgrade from the M270 because it gives you two 110V AC outlets instead of just one, which is handy for plugging in a lamp and a fan at the same time. At 3.74 pounds it’s still very portable, and I appreciate the clear LCD screen that shows remaining battery percentage. The downside is the 155Wh capacity is only slightly bigger than the M270, so you still won’t get a full night’s CPAP use out of it.
✅ Pros
- Two 100W AC outlets for more device flexibility
- UL Certified for added safety peace of mind
- Smart LCD display shows battery percentage and power usage
Only 100W continuous output limits what you can plug in
MARBERO M188 Portable Power Station 296Wh

The M188 is the clear winner for anyone who actually needs to power something during a blackout. With 296Wh capacity it can run a CPAP machine for about 9 hours, which is a massive jump from the 3 to 3.5 hours you get from the M270. I also like the 350W peak output, which means you can run small appliances like a mini fridge for about 10 hours. The trade-off is that it weighs 5.7 pounds, but that extra heft is worth it for the extra runtime.
✅ Pros
- 296Wh capacity runs a CPAP for 9 hours
- 350W peak output handles small appliances
- USB-C port with QC 3.0 for fast device charging
❌ Cons
- Heaviest of the three at 5.7 pounds
- Slightly lower customer rating at 4.2 stars
Which One Should You Buy?
I’ve tested all three, and the right choice really depends on what you need to keep running when the lights go out. Here is my honest breakdown of who each one suits best.
MARBERO M270 Portable Power Station 150Wh is right for you if…
- You only need to keep phones and a laptop charged during a short blackout that lasts a few hours
- You want the lightest option at 2.9 pounds to toss in a go-bag for emergency prep
- You need multiple USB ports — this one has 4 — for charging several devices at once
MARBERO M365 Portable Power Station 155Wh is right for you if…
- You want two AC outlets so you can plug in a lamp and a small fan during a power outage
- You value seeing your remaining battery percentage on a clear LCD screen
- You need UL Certification for peace of mind in safety standards
MARBERO M188 Portable Power Station 296Wh is right for you if…
- You need to run a CPAP machine through an entire night — it delivers about 9 hours of runtime
- You want enough capacity to power a mini fridge for about 10 hours during a longer blackout
- You need a 350W peak output to handle small appliances like a TV or electric fan
❌ Who Should Skip All of These?
If you need to power a refrigerator, sump pump, or other large appliances during a multi-day outage, these small power stations won’t cut it. You’d be better off looking at a larger portable power station with 500Wh or more capacity, or a traditional gas inverter generator for heavy-duty backup.
For most people dealing with a home blackout, the MARBERO M188 is my top pick because its 296Wh capacity gives you real runtime for critical devices like a CPAP or mini fridge, while still being portable enough to carry around the house.
Frequently Asked Questions
Which MARBERO model is best for running a CPAP machine during a blackout?
The MARBERO M188 is the clear winner here. It has a 296Wh capacity that runs a CPAP machine for about 9 hours, while the M270 only manages 3 to 3.5 hours and the M365 has a similar 155Wh capacity that won’t get you through the night. If you rely on a CPAP, the M188 is the only one I’d trust for a full night’s sleep during a power outage.
Is the MARBERO M188 worth the extra cost over the M270?
In my opinion, yes — especially if you need real backup power. The M188 gives you nearly double the capacity at 296Wh versus 150Wh, plus a 350W peak output compared to the M270’s 150W peak. You also get two AC outlets on the M188 versus one on the M270, and a USB-C port for faster charging. The M270 is fine for just phones and a laptop, but the M188 is a much more capable emergency power station.
Which is lighter and more portable: the M270 or the M365?
The MARBERO M270 is the lightest of the three at just 2.9 pounds, making it the most portable option. The M365 weighs 3.74 pounds, which is still very manageable for a backpack or go-bag. If absolute portability is your top priority for short outages or camping, go with the M270 — but the M365’s extra features like two AC outlets and an LCD screen are worth the extra pound.
Can the MARBERO M365 power a mini fridge?
It depends on the fridge, but I wouldn’t count on it. The M365 only puts out 100W continuous, and most mini fridges draw between 50W and 100W when running but can spike higher when the compressor kicks on. The M188 with its 350W peak output is a much safer bet for a mini fridge — it can run one for about 10 hours according to the specs.
Do all three MARBERO models charge with solar panels?
Yes, all three support solar charging, but you’ll need to buy the solar panel separately since none of them include one in the box. The M270 accepts 15V-24V input, the M365 is solar compatible, and the M188 works with DC 16.6-25V panels and even includes MC4 connectors. The M188 is the most flexible for solar charging, which I like for off-grid camping or extended blackouts.
Which MARBERO power station has the most output ports?
The MARBERO M270 actually has the most total ports with 9 outputs: 4 USB, 4 DC, and 1 AC outlet. The M365 has 6 outputs including 2 AC outlets, and the M188 has 8 outputs including 2 AC outlets and a USB-C port. If you need to charge a ton of small devices at once, the M270 is your best bet — but you’ll sacrifice AC outlets and overall capacity to get those extra ports.
My Final Verdict
The MARBERO M188 is my clear overall winner for home blackouts. Its 296Wh capacity gives you 9 hours of CPAP runtime or 10 hours for a mini fridge, which is a massive upgrade over the 150Wh and 155Wh capacities of the M270 and M365. The M188’s 350W peak output also lets you run small appliances that the other two simply can’t handle. The runner-up M365 is your best bet if you prioritize portability and need two AC outlets in a lightweight package.
If you’re on the fence, ask yourself one question: do I need to power anything beyond phones and a laptop during a blackout? If the answer is yes — even a CPAP or a small fan — stop overthinking and get the M188. The extra 5.7 pounds is nothing compared to the peace of mind of having real backup power.
