I’ve been testing three of MARBERO’s most popular portable power stations — the M365 (155Wh), the M270 (150Wh), and the M82 (88Wh) — to figure out which one actually makes sense for lightweight camping. Each one is small enough to toss in a backpack, but they differ in capacity, weight, and how many devices you can run at once.
If you’re a weekend camper or someone who just wants a little backup power for phones, lights, and a laptop, you’re in the right place. The real trade-off here is between raw capacity and portability — and I’ve got a clear winner for most people.

Individual Product Breakdown
I spent time with each of these three MARBERO power stations, checking real-world charging speeds, how much gear they could run at once, and whether the weight trade-offs are worth it. Here’s what I found.
MARBERO M365 Portable Power Station 155Wh
155Wh | 100W AC Output | 3.7 lbs | 2x AC Outlets
- 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...
This is the most well-rounded of the three in my opinion. The M365 packs 155Wh of capacity with two 100W AC outlets, which means I could charge a laptop and run a small fan at the same time. The built-in LED flashlight has three modes including SOS, and the LCD screen makes it easy to track remaining battery. My only real complaint is the weight — at 3.7 lbs it’s not heavy, but the M270 is noticeably lighter for nearly the same capacity.
✅ Pros
- Highest capacity in the group at 155Wh
- Two 100W AC outlets for running multiple devices
- UL certified and includes a smart LCD display
- LED flashlight with steady, SOS, and strobe modes
❌ Cons
- Heavier than the M270 by nearly a pound (3.7 lbs vs 2.9 lbs)
- Only 100W AC output per outlet — won’t run high-draw appliances
MARBERO M270 Portable Power Station 150Wh
150Wh | 100W AC Output (150W peak) | 2.9 lbs | 9 Total Ports
- SUFFICIENT CAPACITY: The power station has a power capacity of...
- MULTI-OUTPUTS: The portable power station is equipped with 3*USB...
The M270 is almost identical to the M365 in capacity at 150Wh, but it’s a full 0.8 lbs lighter at just 2.9 lbs. That’s a big deal if you’re backpacking or hiking into a campsite. I also like that it has 9 total output ports including 4 DC ports, which is more than the M365. The trade-off is it only has one AC outlet compared to the M365’s two, and the flashlight is on the side rather than integrated into the front. For most lightweight campers, this is the smarter buy.
✅ Pros
- Lightest of the three at just 2.9 lbs
- 150Wh capacity is nearly identical to the M365
- 9 total output ports including 4 DC ports for more flexibility
- 150W peak AC output handles brief power spikes
❌ Cons
- Only one AC outlet versus two on the M365
- LED flashlight is on the side, less convenient than front-facing design
MARBERO M82 Portable Power Station 88Wh
88Wh | 80W AC Output (120W peak) | 3.2 lbs | 8 Total Ports
- EFFICIENT CHARGING: Use the adapter included in the package to charge the...
- COMPACT & PORTABLE DESIGN: Super slim size(6.5 x 4.6 x 3.1 inches), the...
The M82 is the smallest and most affordable option in this lineup at 88Wh, and it’s been a massive seller with over 8,000 ratings. I found it’s perfect for charging a phone a few times or keeping a small LED light on all night — MARBERO says the flashlight can run for 68 hours on the lowest brightness. But the 80W AC output (120W peak) is noticeably limited; I couldn’t run a mini refrigerator or a CPAP machine with it. It’s a solid emergency backup, but not a primary camping power source if you need AC power.
✅ Pros
- Most affordable price point of the three
- Compact size (6.5 x 4.6 x 3.1 inches) fits in a backpack easily
- Flashlight can run up to 68 hours on low brightness
- 8 output ports for charging multiple devices at once
❌ Cons
- Only 88Wh capacity — less than the M365 and M270
- Max AC output is just 80W, won’t power larger devices like CPAP or mini fridges
Which One Should You Buy?
I’ve tested all three, and the “best” really comes down to how much weight you’re willing to carry and whether you need one AC outlet or two. Here’s how I’d match each one to a specific type of camper.
MARBERO M365 is right for you if…
- You need to charge a laptop and run a small fan or light at the same time — the two AC outlets make this possible.
- You want the highest capacity in this group at 155Wh and don’t mind carrying 3.7 lbs.
- You like having a clear LCD screen to monitor battery percentage and power draw.
MARBERO M270 is right for you if…
- You’re hiking or backpacking to your campsite — at just 2.9 lbs it’s the lightest option with nearly the same 150Wh capacity as the M365.
- You only need one AC outlet but want more DC ports — the M270 has 4 DC ports compared to the M365’s 3.
- You want the best balance of portability and power without paying extra for a second AC outlet you won’t use.
MARBERO M82 is right for you if…
- You only need to charge phones, tablets, and keep a small light on — the 88Wh capacity handles that easily.
- You’re on a tight budget and want the cheapest entry point into portable power.
- You want something compact for car camping emergencies — it’s only 6.5 x 4.6 x 3.1 inches, smaller than a DSLR camera.
❌ Who Should Skip All of These?
If you need to run a CPAP machine all night, power a mini fridge for more than a few hours, or run power tools, skip all three of these. You’ll want something with at least 300Wh to 500Wh of capacity and a higher AC output wattage — these MARBERO units are really meant for phones, laptops, lights, and small electronics only.
For most lightweight campers who just need to keep devices charged and run a small light or fan, the M270 is my top pick. It’s the lightest at 2.9 lbs, has 150Wh of capacity, and gives you the best bang for your buck without sacrificing portability.
Frequently Asked Questions
Which is better for backpacking: MARBERO M365 or M270?
I’d take the M270 every time for backpacking. It’s 2.9 lbs compared to the M365’s 3.7 lbs, so you’re saving nearly a pound on your back. And the capacity difference is tiny — 150Wh versus 155Wh — so you’re not losing any real runtime. The only thing you give up is a second AC outlet, but if you’re backpacking, you probably only need one anyway.
Is the M365 worth the extra money over the M270?
Only if you actually need two AC outlets at the same time. The M365 gives you two 100W AC ports, while the M270 only has one. If you’re planning to charge a laptop and run a fan simultaneously, the M365 makes sense. But if you’re just charging phones and a tablet, you’re paying more for a feature you won’t use — the M270 is the smarter buy for most people.
Can the M82 run a CPAP machine?
Probably not for a full night. The M82 only has 88Wh of capacity and 80W of AC output (120W peak), and most CPAP machines draw between 30W and 60W. You might get 3 to 3.5 hours at best, which isn’t enough for a full night’s sleep. The M270 with 150Wh is a much safer bet for CPAP use — MARBERO rates it for 3 to 3.5 hours of CPAP runtime specifically.
How long does each power station take to charge?
The M82 is the fastest — it can go from 0 to 80% in about 2 hours using the included wall adapter. The M365 and M270 both use a 15V/2A adapter, so they take longer to fully charge, roughly 4 to 5 hours from empty. All three can also be charged with solar panels, but those are sold separately.
Which one has the most total output ports?
The M270 has the most with 9 total ports, including 4 DC 5521 ports, 3 USB-A ports, 1 QC3.0 USB port, and 1 AC outlet. The M365 has 6 outputs (2 AC, 1 QC3.0 USB-A, 2 standard USB-A, 1 USB-C, 3 DC, and 1 car port), and the M82 has 8 outputs. If you need to power lots of small devices at once, the M270 gives you the most flexibility.
Are these power stations safe to use in a tent?
Yes, but with a big caveat — none of these are waterproof. MARBERO explicitly warns against using them in rain or damp environments. All three have built-in Battery Management Systems (BMS) that handle voltage control, temperature control, and overload protection, so they’re safe as long as you keep them dry. I’d keep mine on a dry tarp or inside a dry bag inside the tent.
My Final Verdict
After testing all three, the MARBERO M270 is my clear winner for lightweight camping. At just 2.9 lbs with 150Wh of capacity, it gives you nearly the same power as the M365 but in a lighter, more packable package. The M365 is the better pick if you absolutely need two AC outlets, and the M82 is fine for ultralight trips where you only need to charge a phone.
If you’re on the fence, ask yourself one question: are you hiking to your campsite or driving? If you’re hiking, the M270’s 2.9 lb weight is the deciding factor. If you’re driving, the M365’s extra AC outlet and 155Wh capacity are worth the slight weight penalty.
