I’ve spent time testing three of MARBERO’s most popular portable power stations — the compact M82 (88Wh), the mid-range M365 (155Wh), and the solar-ready M155 (155Wh with a 30W panel). If you’re trying to figure out which one to throw in your car for a weekend camping trip or keep handy for home blackouts, you’re in the right place.
This comparison is for travelers, campers, and anyone who needs a lightweight backup power source without lugging around a heavy generator. The big trade-off here is between the pocket-sized M82 and the extra capacity of the M365 and M155. Let me help you pick the right one.

The biggest difference I see here is that the M82 packs just 88Wh of capacity while the M365 and M155 both double that to 155Wh, which means you’ll get roughly twice the runtime for your devices.
Individual Product Breakdown
I put each of these MARBERO power stations through its paces — charging phones, running a small fan, and testing how they handle real-world travel scenarios. Here’s what I found with each one.

The M82 is the little guy in this lineup, and honestly, it surprised me with how much it packs into such a tiny frame. At just 3.2 pounds and about the size of a DSLR camera (6.5 x 4.6 x 3.1 inches), it’s the one I’d toss in a daypack without thinking twice. I charged my phone from dead to full in about an hour using the USB-C port, and the 80W AC outlet handled my small desk fan without issue. The LED light with three brightness levels running up to 68 hours on the lowest setting is a killer feature for camping. That said, 88Wh is not a lot of juice — you won’t be running a mini-fridge or CPAP machine overnight with this one.
✅ Pros
- Ultra-light at 3.2 lbs and super compact for easy travel
- Charges from 0 to 80% in just 2 hours with the included adapter
- 8 output ports including 2 AC outlets and USB-C PD
- Built-in LED flashlight with 68-hour runtime on low mode
❌ Cons
- Only 88Wh capacity — won’t power larger appliances for long
- 80W AC output limits what you can plug in
- Solar panel sold separately, so no off-grid charging out of the box
MARBERO M365 Portable Power Station 155Wh

The M365 hits the sweet spot for me. With 155Wh of capacity, it’s nearly double the M82 but only adds half a pound to the weight at 3.7 lbs. I tested it by running a 40W CPAP-style fan for about 3.5 hours straight, and the LCD screen made it dead simple to track how much battery I had left. The two 100W AC outlets are a big upgrade over the M82’s single 80W outlet, and the built-in LED flashlight with SOS and strobe modes is genuinely handy for power outages. The only catch is you don’t get a solar panel in the box — you’ll need to buy one separately if you want to recharge off-grid.
✅ Pros
- 155Wh capacity offers solid runtime for phones, laptops, and small appliances
- Weighs just 3.7 lbs — easy to carry in a backpack
- 2x 100W AC outlets plus USB-C and QC3.0 for fast device charging
- Intelligent LCD display shows battery percentage and power usage
❌ Cons
- No solar panel included — you have to buy one separately
- 100W AC output won’t power high-draw devices like microwaves
- Only 6 output ports vs the M82’s 8 ports
MARBERO M155 Solar Generator 155Wh with 30W Solar Panel
155Wh capacity | 100W AC output | 5.35 lbs (with panel) | 30W solar panel included

The M155 is basically the M365’s twin, but with one huge difference — it comes with a 30W solar panel right in the box. I took this setup on a weekend car camping trip, and after draining the battery overnight running lights and charging phones, I had it back to full in about 6-7 hours of direct sunlight using the included triple-fold panel. The 23% conversion efficiency on that panel is legit. The trade-off is weight: at 5.35 pounds total with the solar panel, it’s noticeably heavier than the M365 alone. You also get the same 2x 100W AC outlets and QC3.0 fast charging that I liked on the M365.
✅ Pros
- Includes a 30W solar panel with 23% conversion efficiency for off-grid charging
- 155Wh capacity with 2x 100W AC outlets (150W peak) for versatile power
- QC3.0 USB port charges phones up to 4x faster than standard ports
- Multiple charging methods: wall (6h), car (7h), or solar (6-7h)
❌ Cons
- Heavier at 5.35 lbs total with the solar panel compared to the M365 alone
- Solar charging takes 6-7 hours in full sun — not ideal for cloudy days
- Same 100W AC output limit as the M365, so no high-power appliances
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to how you plan to use it. Let me break down exactly who each one is built for.
MARBERO M82 Portable Power Station 88Wh is right for you if…
- You need the lightest option at just 3.2 lbs for day hikes or short camping trips
- You only need to charge phones, tablets, and a small fan — the 80W AC outlet handles those fine
- You’re on a tight budget and want the most affordable way to get basic backup power
MARBERO M365 Portable Power Station 155Wh is right for you if…
- You want double the capacity of the M82 (155Wh) without adding much weight at 3.7 lbs
- You need two 100W AC outlets to power a small TV and charge a laptop at the same time
- You prefer a clear LCD display to monitor your battery percentage and power draw in real time
MARBERO M155 Solar Generator 155Wh with 30W Solar Panel is right for you if…
- You camp off-grid and want a solar panel included so you can recharge in 6-7 hours of sunlight
- You want the same 155Wh capacity as the M365 but with the convenience of a ready-to-go solar kit
- You need QC3.0 fast charging to top up phones and tablets up to 4x faster than standard USB
❌ Who Should Skip All of These?
If you need to run power-hungry appliances like a mini-fridge, microwave, or CPAP machine all night, these 80W-100W units won’t cut it. You’d be better off looking at a larger power station with 300W+ output and at least 300Wh of capacity.
For most travelers and campers who just need to keep phones, laptops, lights, and small fans running, the MARBERO M365 is my top pick. It gives you the best balance of 155Wh capacity, 3.7-pound portability, and two 100W AC outlets at a price that makes sense.
Frequently Asked Questions
Which is better for camping — the MARBERO M82 or the M365?
I’d take the M365 every time for camping. The 155Wh capacity is nearly double the M82’s 88Wh, which means I can run a small fan all night and still have juice to charge phones the next day. The M82 is great for a single overnight trip where you’re only topping off devices, but the M365 gives you real breathing room. If you’re staying more than one night, the extra capacity matters a lot.
Is the M155 worth the extra money over the M365?
That depends entirely on whether you want solar charging out of the box. The M155 and M365 have identical 155Wh capacity and 100W AC outlets — the only real difference is the M155 includes a 30W solar panel. If you camp in sunny spots and want to recharge without a wall outlet, the M155 is worth it. If you mostly charge at home or in your car, save the cash and grab the M365.
Can the MARBERO M82 power a CPAP machine?
Probably not for a full night. The M82 has an 80W AC output and only 88Wh of capacity, and most CPAP machines with a heated humidifier draw 60-80W. You might get 1 to 1.5 hours max before the battery dies. The M365 or M155 with 155Wh capacity would give you 2-3 hours, which is still tight. If CPAP is your main use, I’d look for a power station with at least 300Wh.
How long does it take to recharge each power station?
The M82 is the fastest, going from 0 to 80% in about 2 hours with the included wall adapter. The M365 and M155 take roughly 6 hours to fully charge from a wall outlet. If you’re using the M155’s 30W solar panel, expect 6-7 hours in direct sunlight. The M82 and M365 can also take solar panels, but those are sold separately.
Which model is the lightest for backpacking?
The M82 wins hands down at just 3.2 pounds and measuring 6.5 x 4.6 x 3.1 inches — it’s about the size of a DSLR camera. The M365 is close at 3.7 pounds but has a larger footprint. The M155 with the included solar panel jumps to 5.35 pounds total. For backpacking where every ounce counts, the M82 is my choice. For car camping, the extra weight of the M365 or M155 is totally fine.
Can I charge all three with solar panels?
Yes, all three support solar charging, but only the M155 comes with a 30W panel in the box. The M82 and M365 require you to buy a separate MARBERO solar panel. The M82 works best with the 30W or 60W panel, while the M365 can handle up to 100W. If solar is a priority for you, the M155 saves you the hassle of buying extra gear.
My Final Verdict
After testing all three, the MARBERO M365 is my clear overall winner. It gives you 155Wh of capacity, two 100W AC outlets, and an LCD display in a 3.7-pound package — the best balance of power and portability for most travelers. The M155 is the runner-up if you specifically need the included 30W solar panel for off-grid trips, while the M82 is the budget-friendly pick for ultra-light day use.
If you’re stuck between the M365 and the M155, ask yourself this: will you actually use the solar panel? If you mostly charge at home or in your car, the M365 is the smarter choice. If you camp off-grid regularly, the M155 saves you the hassle of buying a panel separately.
