I’ve tested the MARBERO M82 with its compact 88Wh battery, the M155 with a larger 155Wh capacity, and the M270 with 150Wh of power to see which one is actually best for charging phones, laptops, and other small gear. All three are built for camping and emergencies, but they serve different needs.
If you’re looking for a lightweight power station to keep your phone and tablet running on a weekend trip, this comparison will help you pick the right one. The main trade-off here is portability versus capacity, and I’ll break down exactly who should buy which model.

Individual Product Breakdown
I spent time charging phones, laptops, and small camping gear with each of these MARBERO power stations to see how they handle real-world use. Here’s what I found after testing all three.
MARBERO M82 Portable Power Station 88Wh Camping Lithium Battery Solar Generator
88Wh capacity | 80W AC output | 3.2 lbs | 8 output ports
No products found.
The M82 is the smallest of the bunch at just 6.5 x 4.6 x 3.1 inches and 3.2 lbs, which makes it a no-brainer for tossing in a backpack. I was able to fully charge my phone in about an hour and my tablet in 1.5 hours thanks to the USB-C PD port. The 88Wh battery is enough for a weekend trip, but don’t expect it to run anything above 80W — my mini fridge was a no-go. It’s perfect for keeping your phone, tablet, and a small light going, but not much more.
✅ Pros
- Ultra-lightweight at just 3.2 lbs — easy to carry anywhere
- 8 output ports including USB-C PD for fast laptop charging
- LED flashlight with 3 brightness levels and SOS mode
- Charges from 0 to 80% in just 2 hours with included adapter
❌ Cons
- Only 88Wh capacity — won’t run larger devices over 80W
- AC output is limited to 80W continuous, no heavy appliances
- Solar panel sold separately, adds cost

The M155 hit the sweet spot for me — it packs 155Wh of juice (enough to charge a smartphone 8 to 10 times) while still being light enough at 3.7 lbs to toss in a daypack. I ran my CPAP machine for a full night and still had power left over for my phone in the morning. The 100W AC outlet handled my laptop without breaking a sweat. My only gripe is that it only has 2 AC outlets, so you’ll need a power strip if you want to plug in multiple wall-powered devices.
✅ Pros
- 155Wh capacity charges phones 8-10 times or runs a CPAP all night
- Weighs only 3.7 lbs — great balance of power and portability
- Fast charging from 0 to full in about 4-5 hours with included adapter
- Advanced BMS with over-voltage and short-circuit protection
❌ Cons
- Only 2 AC outlets — limited for multiple wall-powered devices
- Solar panel not included, must buy separately
- No USB-C PD port, only QC 3.0 for fast charging

The M270 surprised me with its 9 total output ports — 4 USB and 4 DC — so you can charge a ton of small devices at once. It weighs just 2.9 lbs, which is actually lighter than the M82 despite having a 150Wh battery. I was able to run a CPAP machine for 3 to 3.5 hours and still had juice for my phone and a mini fan. The dual LED flashlights with SOS mode are a nice touch for emergencies. The downside is the AC output is capped at 100W continuous, so it won’t power anything heavy like a mini fridge.
✅ Pros
- 9 ports total — 4 USB, 4 DC, and 1 AC — great for multi-device charging
- Weighs only 2.9 lbs, lighter than the M82 despite larger capacity
- Dual LED flashlights with steady and SOS modes for emergencies
- Charges phone 24 times or runs CPAP for 3+ hours
❌ Cons
- AC output limited to 100W — won’t run larger appliances
- No USB-C PD port for fast laptop charging
- Solar panel not included, adds to overall cost
Which One Should You Buy?
I’ve tested all three, and the right choice really comes down to how much gear you need to power and how far you’re carrying it. Here’s my honest breakdown of who each model fits best.
MARBERO M82 is right for you if…
- You need something ultra-light at 3.2 lbs that fits in a backpack for a day hike or short camping trip
- You mainly want to charge phones, tablets, and a laptop on the go without lugging a heavy brick
- You’re on a tight budget and just need basic power for small devices under 80W
MARBERO M155 is right for you if…
- You need enough juice (155Wh) to run a CPAP machine all night or charge a laptop 6 to 9 hours
- You want the best balance of capacity and weight at 3.7 lbs for weekend camping or RV trips
- You plan to charge up to 7 devices at once including a laptop, phone, and camera
MARBERO M270 is right for you if…
- You need to power lots of small devices at once with 9 total ports — 4 USB and 4 DC outputs
- You want a 150Wh battery that’s still light at 2.9 lbs and can charge a phone 24 times
- You value built-in dual LED flashlights with SOS mode for emergency or hurricane prep
❌ Who Should Skip All of These?
If you need to run power-hungry appliances like a mini fridge, a small air conditioner, or power tools for more than an hour, none of these will cut it — you’re better off looking at a larger power station with at least 300Wh or a gas generator. These MARBERO units are strictly for phones, laptops, lights, and CPAP machines under 100W.
For the average person who wants a portable power station for camping or emergency backup, I’d pick the MARBERO M155 — it gives you the most usable capacity at 155Wh without weighing you down, and it handled everything I threw at it.
Frequently Asked Questions
Which MARBERO model is best for running a CPAP machine overnight?
I’d go with the M155 or M270 since both have enough capacity — 155Wh and 150Wh respectively — to run a CPAP machine for 3 to 3.5 hours. The M82 only has 88Wh, so it’ll struggle to get you through a full night. Between the two, the M155 is my pick because it has a 100W AC outlet that handles most CPAP machines without issue, plus it’s still light at 3.7 lbs for packing.
Is the MARBERO M82 powerful enough to charge a laptop?
Yes, but only if your laptop draws under 80W. The M82’s AC output is capped at 80W, and the USB-C PD port can charge most laptops in about 2 hours. I tested it with a standard 60W laptop and it worked fine. Just don’t try to charge a high-performance gaming laptop or a MacBook Pro while also running other devices — you’ll hit the limit fast.
How long does it take to fully charge each power station from a wall outlet?
The M82 is the fastest — it goes from 0 to 80% in just 2 hours with the included adapter. The M155 and M270 both take longer, roughly 4 to 5 hours for a full charge using their included power adapters. If you’re in a hurry, the M82 wins hands down, but the larger capacity models take more time to top off.
Which MARBERO power station has the most output ports?
The M270 takes the crown with 9 total ports — 4 USB, 4 DC 5521 outputs, and 1 AC socket. That’s perfect if you want to charge multiple phones, a camera, a mini fan, and a laptop all at once. The M82 has 8 ports and the M155 has 7, so the M270 is the clear winner for multi-device charging.
Can I charge any of these with a solar panel?
All three support solar charging, but you’ll need to buy the panel separately — it’s not included in the box. The M82 works with MARBERO’s dedicated 30W or 60W solar panel, while the M270 accepts panels in the 15V to 24V range. For the M155, any compatible solar panel should do the trick. Just know that solar charging is slow, so plan ahead if you’re going off-grid.
Which MARBERO model is the lightest and most portable?
The M270 is actually the lightest at 2.9 lbs, which surprised me since it has a 150Wh battery. The M82 comes in at 3.2 lbs, and the M155 is the heaviest at 3.7 lbs. But the M82 is physically the smallest at 6.5 x 4.6 x 3.1 inches, so if pure pocketability matters most, that’s the one I’d grab for a day hike.
My Final Verdict
After testing all three, the MARBERO M155 is my clear winner for most people. It packs 155Wh of capacity — enough to run a CPAP all night or charge a laptop for 6 to 9 hours — while staying light at just 3.7 lbs. The M82 is my runner-up if you prioritize pocketability at 3.2 lbs, and the M270 wins for anyone who needs 9 ports for multiple gadgets.
If you’re on the fence, ask yourself this: do you want to charge one device on a day hike (get the M82) or keep your CPAP and phone running on a weekend trip (get the M155)? The M155 gives you the most versatility without weighing you down.
