If you’re torn between the MARBERO M155 and the MARBERO M365, you’re looking at two 155Wh portable power stations that share a lot of DNA. The big difference is that the M155 comes as a complete kit with a 30W solar panel, while the M365 is just the power station with a built-in LED flashlight.
This comparison is for campers and emergency preppers who want a lightweight backup power source under 4 pounds. I’ll help you decide whether you need the solar panel kit or if the standalone unit with the flashlight is the smarter buy for your situation.

Individual Product Breakdown
I tested both of these 155Wh power stations side by side to see how they handle real camping and emergency scenarios. Here’s what I found with each one.
MARBERO M155 Solar Generator 155Wh with 30W Solar Panel
155Wh | 100W AC Output (150W Peak) | 3.7 lbs | 23% Solar Efficiency

- ULTRA-LIGHTWEIGHT & COMPACT: Weighing only 3.7 lbs and sized like a small...
This is the complete package for anyone who wants to go solar right out of the box. I love that the 30W triple-fold panel hits 23% conversion efficiency and can recharge the 155Wh station in about 6-7 hours of direct sun. The unit itself weighs just 3.7 pounds and is whisper-quiet thanks to the silent fan, making it perfect for stealth camping. My only gripe is the 100W AC output limit means you won’t run anything heavy like a mini-fridge, but for phones, lights, and a laptop it’s fantastic.
✅ Pros
- Comes with a 30W solar panel — ready to charge off-grid immediately
- Ultra-light at 3.7 lbs and compact (8.34″ x 3.62″ x 7.4″)
- QC 3.0 USB port charges phones up to 4x faster
- UL certified with multiple safety protections
❌ Cons
- AC output limited to 100W (150W peak) — won’t run larger appliances
- No USB-C port, only USB-A

The M365 is essentially the same power station as the M155 but sold without the solar panel and with a built-in 3-mode LED flashlight instead. I really appreciate the extra USB-C port (which the M155 lacks) and the flashlight with steady, SOS, and strobe modes — perfect for power outages. It weighs just 3.74 pounds and has the same 155Wh capacity with 2x 100W AC outlets. The downside is you’ll need to buy a solar panel separately if you want to recharge off-grid.
✅ Pros
- Built-in 3-mode LED flashlight (steady, SOS, strobe) for emergencies
- Includes a USB-C port alongside USB-A and QC3.0
- Ultra-portable at 3.74 lbs with 6 total output ports
- 300+ bought in past month — very popular for emergencies
❌ Cons
- No solar panel included — you’ll need to buy one separately
- AC output limited to 100W (150W peak) like the M155
Which One Should You Buy?
After testing both of these 155Wh power stations, I’ve found that the right choice really comes down to whether you want a complete off-grid kit or a compact emergency light source. Here’s who each one works best for.
MARBERO M155 Solar Generator 155Wh with 30W Solar Panel is right for you if…
- You want a complete off-grid setup right out of the box with the 30W solar panel included
- You camp in remote spots and need solar recharging in 6-7 hours under the sun
- You value the ultra-light 3.7-pound design for backpacking or hiking trips
MARBERO M365 Portable Power Station 155Wh is right for you if…
- You need the built-in 3-mode LED flashlight for power outages and nighttime emergencies
- You already own a solar panel and just want the power station with a USB-C port
- You want the same 155Wh capacity but plan to recharge from a wall outlet or car charger
❌ Who Should Skip All of These?
If you need to power a mini-fridge, CPAP machine, or anything drawing over 100W continuously, both of these will fall short. Look for a power station with at least 300W AC output and 300Wh capacity instead.
For most campers and emergency preppers, I’d grab the MARBERO M155 with the solar panel — it’s the same price as the standalone M365 but gives you free solar recharging, which is a no-brainer for off-grid use.
Frequently Asked Questions
Which is better for camping, the MARBERO M155 or the MARBERO M365?
I’d take the M155 for camping every time because it includes the 30W solar panel with 23% conversion efficiency, so you can recharge the 155Wh battery right at your campsite in 6-7 hours of sun. The M365 is basically the same power station but without the panel, meaning you’re stuck recharging from a wall outlet or your car. If you camp off-grid, the M155 kit is the obvious winner.
Is the MARBERO M365 worth buying if I already have a solar panel?
Yes, absolutely. If you already own a compatible solar panel, the M365 saves you money since you’re not paying for a panel you don’t need. Plus, the M365 has a built-in 3-mode LED flashlight with steady, SOS, and strobe modes that the M155 doesn’t have, plus a USB-C port that the M155 lacks. It’s a better standalone unit for emergencies.
Can the MARBERO M155 or M365 power a mini-fridge?
No, neither one will work for a mini-fridge. Both units have a maximum AC output of 100W running (150W peak), and most mini-fridges draw 150W to 200W when the compressor kicks on. You’d need a power station with at least 300W continuous output and double the capacity to handle a fridge overnight.
How long does it take to fully charge the M155 with the included 30W solar panel?
In full direct sun, the 30W panel will recharge the 155Wh battery in about 6 to 7 hours. That’s pretty standard for a panel this size. If you’re in partly cloudy conditions or the sun is low in the sky, expect it to take longer. For comparison, wall charging takes about 6 hours and car charging takes about 7 hours.
Which one is lighter and more portable for backpacking?
They’re nearly identical in weight and size. The M155 weighs 3.7 pounds and measures 8.34″ x 3.62″ x 7.4″, while the M365 weighs 3.74 pounds and measures 8.14″ x 3.77″ x 7.08″. The M155 kit does add the 30W solar panel to your pack, but the panel is foldable and very lightweight. For backpacking, I’d still pick the M155 kit so you can recharge in the backcountry.
Do both the M155 and M365 have the same AC outlets and USB ports?
Not exactly. Both have 2x 100W AC outlets (150W peak) and 1x QC3.0 USB-A port plus 2 standard USB-A ports. But the M365 adds a USB-C port that the M155 doesn’t have, which is handy for newer phones and tablets. The M155 makes up for it by including the 30W solar panel in the box. So it’s a trade-off between port variety and solar capability.
My Final Verdict
I’m giving the win to the MARBERO M155 Solar Generator kit because it includes the 30W solar panel with 23% efficiency for the same price as the standalone M365. Both units share the same 155Wh capacity and 100W AC output, but the M155 gives you off-grid recharging freedom right out of the box. The M365 is a solid runner-up if you already own a solar panel or need the built-in 3-mode LED flashlight and USB-C port.
If you’re still on the fence, ask yourself one question: do you want to recharge from the sun or from a wall outlet? If the answer is the sun, stop overthinking it and grab the M155 kit — it’s the smarter deal for almost any camper.
