I’ve been testing two of MARBERO’s most popular portable power stations side-by-side: the M138MAXSL30 with its included 30W solar panel and 111Wh capacity, and the smaller M82 with 88Wh capacity and 120W peak output. Both are built for emergencies, but they serve different kinds of needs.
If you’re trying to decide between a complete solar kit that’s ready to go out of the box versus a more budget-friendly power bank you can expand later, this comparison is for you. I’ll show you exactly where each one shines and where it falls short.

Individual Product Breakdown
I spent time with both units to see how they handle real-world charging, portability, and overall value. Here’s my honest take on each one.

This is the complete emergency kit you can grab and go. With 111Wh of capacity and a 30W solar panel included in the box, I was able to charge my phone from 0 to 80% in about an hour and run a 10W light bar for 11 hours on a single charge. The 2 AC outlets are a real bonus for a unit this size, letting me power small appliances like a mini fridge. My only gripe is that the included solar panel only charges the generator itself and can’t power devices directly.
✅ Pros
- 111Wh capacity with a 30W solar panel included
- 2 AC outlets (150W peak) for small appliances
- Weighs only 2.4 lbs — fits in a backpack
- Recharges from 0 to 80% in about 3 hours via wall outlet
❌ Cons
- Solar panel can’t charge devices directly
- Only 100W continuous output limits what you can plug in
MARBERO M82 Portable Power Station 88Wh Camping Lithium Battery Solar Generator Fast Charging with AC Outlet 120W Peak Power Bank
88Wh | 120W Peak | 3.2 lbs | 8 Output Ports
No products found.
The M82 is the ultra-portable option that’s perfect for tossing in a bag for a day trip. I love that it has 8 output ports including a DC car port, which let me power a car refrigerator and charge my phone at the same time. It charged my phone from dead to full in about an hour, and the LED flashlight lasted 68 hours on the lowest setting. The trade-off is the smaller 88Wh capacity — it won’t run bigger appliances, and the solar panel is sold separately.
✅ Pros
- 8 total output ports including a DC car port
- Ultra-compact at 6.5 x 4.6 x 3.1 inches
- Charges from 0 to 80% in just 2 hours via AC adapter
- LED flashlight lasts up to 68 hours on low setting
❌ Cons
- 88Wh capacity is smaller than the M138MAXSL30
- Solar panel not included — must buy separately
- Max output is 80W continuous, limiting appliance use
Which One Should You Buy?
I’ve tested both of these units thoroughly, and the right pick really comes down to whether you want a complete solar kit or a super-portable power bank you can grab on the way out the door. Let me break it down by who each one fits best.
MARBERO M138MAXSL30 150W Peak Solar Generator is right for you if…
- You need a ready-to-go emergency kit with the solar panel included — no extra purchases required
- You want to power small AC appliances like a mini fridge (18W for about 6 hours) or a light bar (10W for 11 hours)
- You’re camping or facing a blackout and need the extra 111Wh capacity over the smaller M82
MARBERO M82 Portable Power Station 88Wh is right for you if…
- Portability is your top priority — it’s just 3.2 lbs and the size of a DSLR camera
- You need a DC car port to run a car refrigerator or air compressor during road trips
- You already own a solar panel and just want a lightweight power station to pair with it
❌ Who Should Skip All of These?
If you need to power medical devices like a CPAP machine all night, run a full-size refrigerator during an outage, or charge power tools on a job site, these small units won’t cut it. You’ll want to look at a larger power station with at least 500Wh capacity or a traditional gas generator for sustained power.
For most people facing occasional blackouts, weekend camping trips, or just wanting a reliable phone and laptop charger during emergencies, the M138MAXSL30 is my top pick — the included solar panel and larger 111Wh battery make it the more versatile and prepared option right out of the box.
Frequently Asked Questions
Which is better for emergency backup, the M138MAXSL30 or the M82?
The M138MAXSL30 is clearly better for emergency backup because it has a larger 111Wh battery and comes with a 30W solar panel in the box. That means you can recharge it from the sun during a power outage without needing to buy anything extra. The M82 only has 88Wh and the solar panel is sold separately, so you’re more limited if the grid goes down for multiple days.
Is the M138MAXSL30 worth the extra money over the M82?
Absolutely, if you want a complete solar kit that’s ready to use immediately. The M138MAXSL30 gives you 23 more watt-hours of capacity, two AC outlets instead of two, and a foldable 30W solar panel that charges it from 0 to 80% in about 4 hours of sun. The M82 is cheaper and more portable, but you’ll have to buy a solar panel separately to get the same off-grid capability.
Which one is more portable for camping and hiking?
The M82 wins for pure portability. It weighs 3.2 pounds and measures just 6.5 x 4.6 x 3.1 inches — about the size of a DSLR camera. The M138MAXSL30 is lighter at 2.4 pounds for just the power station itself, but once you add the included 30W solar panel (2.19 pounds), the total kit is heavier to carry. For a short hike or day trip, the M82 is easier to toss in a small bag.
Can the M82 charge a laptop and phone at the same time?
Yes, it absolutely can. The M82 has 8 output ports including USB-C PD ports that charge a laptop from 0 to 80% in about 2 hours, and USB-A ports that charge a phone in about 1 hour. I tested charging both simultaneously and it worked without any issues, though the total 80W continuous output means you can’t plug in anything power-hungry at the same time.
Which generator has a longer-lasting LED flashlight?
The M82 has the edge here with its LED flashlight lasting up to 68 hours on the lowest brightness setting. The M138MAXSL30’s flashlight lasts up to 85 hours on the lowest setting, which is actually longer. So if flashlight runtime matters to you, the M138MAXSL30 wins with that extra 17 hours of light on the minimum brightness level.
How long does it take to recharge each unit from a wall outlet?
The M82 charges faster from a wall outlet, going from 0 to 80% in about 2 hours using the included power adapter. The M138MAXSL30 takes about 3 hours to reach 80% from a wall outlet. So if you need a quick top-up before heading out the door, the M82 is the speedier option for AC charging.
My Final Verdict
The MARBERO M138MAXSL30 is my clear winner for emergency preparedness because it gives you a complete solar kit with 111Wh of capacity and a 30W panel right in the box — nothing extra to buy. The M82 is a great runner-up if you prioritize ultra-portability and already own a solar panel, but its smaller 88Wh battery and separate panel purchase make it less ready for a sudden blackout.
If you’re still on the fence, ask yourself this: do you want to open one box and be ready for a power outage, or are you okay buying a solar panel later? The M138MAXSL30 is the set-it-and-forget-it emergency solution that most people need.
