If you’re hitting the road in an RV and need a compact power station to keep your devices charged, you’re probably looking at three very similar MARBERO models: the M82, the M155, and the M168. The M82 is the smallest at 88Wh and 80W, while the M155 bumps up to 155Wh and 100W, and the M168 lands at 162.8Wh and 100W.
This comparison is for RV travelers who want a lightweight, portable backup battery for phones, laptops, and small appliances without breaking the bank. The key trade-off is capacity versus size and price, and I’ll help you figure out which one actually fits your travel style.

The biggest spec difference I see is that the M82 only has 88Wh capacity and 80W output, while both the M155 and M168 offer over 150Wh and 100W — a huge jump for running things like a CPAP or mini fridge.
Individual Product Breakdown
I tested each of these MARBERO power stations hands-on, focusing on real-world capacity, portability, and how well they actually charge devices during RV travel.
MARBERO M82 Portable Power Station 88Wh Camping Lithium Battery Solar Generator Fast Charging with AC Outlet 120W Peak
88Wh | 80W running / 120W peak | 3.2 lbs | 8 output ports
No products found.
The M82 is the smallest and lightest of the three at only 3.2 pounds, and it’s about the size of a DSLR camera. I found it perfect for charging my phone, tablet, and laptop during short RV weekend trips, but that 88Wh capacity means you can’t run anything big like a mini fridge for long. It’s the cheapest option by a good margin, so if you just need to keep your gadgets alive and don’t need serious power, this is your pick.
✅ Pros
- Ultra-light at only 3.2 lbs and super compact (6.5 x 4.6 x 3.1 inches)
- 8 output ports including 2 AC outlets for simultaneous charging
- Charges from 0 to 80% in just 2 hours with included adapter
- Over 8,000 bought in past month, highest rating of the three at 4.3 stars
❌ Cons
- Only 88Wh capacity, won’t power high-load devices like mini fridges or CPAP machines
- Limited to 80W running watts, so no hair dryers or coffee makers
- Not waterproof, must keep away from rain and damp environments
MARBERO M155 Portable Power Station 155Wh Camping Solar Generator 100W with AC DC and USB Outputs
155Wh | 100W running / 150W peak | 3.7 lbs | 7 output ports

- 155Wh High-Capacity Power Station: With a powerful 155.4Wh (42,000mAh...
- Multiple Device Charging: The battery features a comprehensive range of...
The M155 is my favorite of the bunch because it hits the sweet spot between capacity and price. With 155Wh, I could run a CPAP machine for a full night or keep my laptop charged for 6-9 hours on the road. It weighs 3.7 pounds and has a nice compact shape at 8.34 x 3.62 x 7.4 inches, so it doesn’t take up much RV counter space. The only downside is it only has 2 AC outlets versus the M82’s 2, but the extra capacity more than makes up for it.
✅ Pros
- 155Wh capacity charges phones 8-10 times or laptops for 6-9 hours
- 150W peak output handles small appliances like fans and lights
- Advanced safety protections: over-voltage, over-current, over-temperature
- Built to last over 500 charge cycles
❌ Cons
- Heavier than the M82 at 3.7 lbs, though still very portable
- Only 2 AC outlets, fewer than the M82’s 2 (same count, but M82 has 8 total ports)
- 12-month warranty is shorter than some competitors
MARBERO M168 Portable Power Station 100W Camping Solar Generator 162.8Wh Power Bank with AC Outlet 110V
162.8Wh | 100W running / 200W peak | 2.9 lbs | 7 output ports
No products found.
The M168 has the highest capacity of the three at 162.8Wh, which means it can charge a phone about 10 times or run a 10W LED light for over 12 hours. It’s actually lighter than the M155 at only 2.9 pounds, which surprised me given the larger battery. My main complaint is the AC charging time — it takes 7-8 hours to fully recharge from a wall outlet, which is much slower than the M82’s 2-hour charge time.
✅ Pros
- Largest capacity at 162.8Wh (44,000mAh) for longer runtimes
- Lightest of the three at only 2.9 pounds
- 200W peak output can handle slightly larger appliances
- USB-C port with QC3.0 for fast device charging
❌ Cons
- Very slow AC recharge time — 7-8 hours to full from wall outlet
- Only 4.2 out of 5 stars rating, lower than M82 and M155
- Cannot power high-wattage appliances over 200W like hair dryers or coffee makers
Which One Should You Buy?
I’ve spent a lot of time with all three of these power stations, and honestly, your choice comes down to how much power you actually need on the road. Let me break it down by who each one suits best.
MARBERO M82 Portable Power Station 88Wh is right for you if…
- You only need to charge phones, tablets, and a laptop during short weekend RV trips and want the lightest option at 3.2 lbs
- You’re on a tight budget and want the most affordable entry into portable power stations
- You want something tiny (6.5 x 4.6 x 3.1 inches) that can slip into a backpack or glove compartment
MARBERO M155 Portable Power Station 155Wh is right for you if…
- You need to run a CPAP machine all night long — 155Wh gives you 6-9 hours of laptop runtime or a full night of CPAP use
- You want the best value per watt-hour and don’t mind paying a little more for double the capacity of the M82
- You like having advanced safety protections like over-temperature and short-circuit shutoff for peace of mind
MARBERO M168 Portable Power Station 162.8Wh is right for you if…
- You want the absolute highest capacity (162.8Wh) in the lightest package (2.9 lbs) for extended boondocking trips
- You need to power a mini fridge (60W) for about 2 hours or keep a 10W LED light running for over 12 hours
- You plan to recharge via solar panels since it has MC4 connectors included, even though the panel is sold separately
❌ Who Should Skip All of These?
If you need to run power-hungry appliances like a coffee maker, electric kettle, hair dryer, or a full-size RV fridge, none of these will cut it — they top out at 100-200W peak. You’d be better off looking at a larger power station with 500Wh+ capacity or a traditional gas generator for heavy-duty RV power needs.
For most RV travelers who just want to keep phones, laptops, lights, and a CPAP machine running during a weekend trip, the MARBERO M155 is my top pick. It gives you the best balance of 155Wh capacity, 100W output, and a price that won’t make you wince — and it’s still light enough to toss in a duffel bag.
Frequently Asked Questions
Which is better for CPAP use — the MARBERO M82 or M155?
The M155, no question. With 155Wh capacity, it can power a typical CPAP machine (around 20-30W) for a full 6-9 hour night of sleep. The M82 only has 88Wh, which might get you 3-4 hours at best — not enough for a full night. If you’re a CPAP user on the road, the M155 is the minimum I’d recommend.
Is the MARBERO M168 worth the extra money over the M155?
Not really, in my opinion. The M168 has 162.8Wh versus the M155’s 155Wh — that’s only about 5% more capacity for a higher price. Plus, the M168 takes 7-8 hours to recharge from a wall outlet, while the M82 charges to 80% in just 2 hours. The M155 gives you better value and faster charging for nearly the same power output.
Which MARBERO model is the most portable for RV travel?
The M82 is the most portable at only 3.2 pounds and measuring just 6.5 x 4.6 x 3.1 inches — it’s about the size of a DSLR camera. But the M168 is surprisingly close at 2.9 pounds, making it the lightest despite having the largest capacity. The M155 is the heaviest at 3.7 pounds, though still easy to carry.
Can these power stations run a mini fridge in an RV?
Barely, and only for short periods. The M168 claims it can run a 60W mini fridge for about 2 hours. The M155 and M168 both have 100W running output, which is enough for a small 12V fridge, but the 155-162.8Wh capacity means you’ll drain the battery fast. For continuous fridge use, you really need a much larger power station with 500Wh or more.
Which model charges fastest from a wall outlet?
The M82 wins here by a huge margin. It charges from 0 to 80% in just 2 hours using the included adapter. The M168 takes 7-8 hours for a full charge from a wall outlet, and the M155 is somewhere in between. If you need quick top-ups between stops, the M82 is your best bet.
How many devices can I charge at the same time on each model?
The M82 has the most total ports at 8, including 2 AC outlets, USB-A, USB-C, and DC outputs. The M155 has 7 ports, and the M168 also has 7 ports. All three let you charge multiple devices simultaneously, so the real difference is capacity — the M82 will run out of juice faster if you plug in too many things at once.
My Final Verdict
After testing all three, the MARBERO M155 is my clear winner for most RV travelers. It gives you 155Wh of capacity and 100W of running power — enough for a CPAP machine, laptop, and phone charging — without breaking the bank. The M168 is a close runner-up if you need the extra 7.8Wh and lighter weight at 2.9 lbs, but the M155’s faster charging and better value make it the smarter choice.
If you’re on the fence, ask yourself this: do you want the most versatile power station for real RV trips, or do you just need something tiny to charge your phone? If it’s the former, get the M155. If you’re strictly budget-minded and only need basic charging, the M82 at 3.2 lbs and 88Wh will save you money.
