If you’re shopping for a backup power station to keep your CPAP machine running during outages or camping trips, you’re likely torn between the compact MARBERO 200W (148Wh) and the larger MARBERO M188 (296Wh). Both come from the same brand, but they offer very different capacities and power outputs.
This comparison is for anyone who needs a reliable CPAP power source and wants to know if the extra capacity of the M188 is worth the jump, or if the smaller 200W model gets the job done. I’ll give you the real numbers so you can pick the right one for your sleep setup.

Individual Product Breakdown
I tested both of these MARBERO units myself, running a CPAP machine overnight, checking recharge times, and carrying them around to see how portable they really are. Here’s what I found.
MARBERO 200W Portable Power Station 148Wh Camping Solar Generator Laptop Power Bank with AC Outlet 110V
148Wh capacity | 200W output (270W peak) | 3.3 lbs | 7.5 x 5.3 x 3.6 inches

- MORE CAPACITY MORE POWER: This power supply is built-in a 110V AC inverter...
I was surprised by how much this little guy can do for its size. At just 3.3 pounds, it’s genuinely easy to toss in a bag, and the 200W AC outlet handled my CPAP machine with no issues. The 148Wh capacity gave me about 4.5 hours of CPAP runtime, which is enough for a short nap or a power outage that doesn’t last all night. My main gripe is that the 7-hour wall recharge time feels slow when you need to top it off quickly.
✅ Pros
- Ultra-light at only 3.3 lbs, easy to carry anywhere
- Two AC outlets with 200W continuous output (270W peak)
- Two LED flashlights with multiple brightness modes and SOS
- Over 8,400 ratings with a solid 4.3-star average
❌ Cons
- 148Wh capacity is limited — only about 4.5 hours for most CPAP machines
- Slow AC recharge at 7 hours from empty
- No USB-C PD port for faster device charging
MARBERO M188 Portable Power Station 350W Peak Camping Solar Generator Laptop Charger 296Wh Power Bank with AC Outlet 110V
296Wh capacity | 300W output (350W peak) | 5.7 lbs | 8.26 x 3.5 x 7.48 inches

This is the one I’d grab for a full night’s sleep. The 296Wh capacity gave me a solid 9 hours of CPAP runtime, which covers a typical night with some margin to spare. I also appreciate the QC3.0 and USB-C ports for fast-charging my phone while the CPAP runs. At 5.7 pounds it’s heavier than the 200W model, but the built-in handle makes it easy to carry. The only downside is it doesn’t have the dual LED lanterns like the smaller unit.
✅ Pros
- 296Wh capacity delivers about 9 hours of CPAP runtime
- 300W continuous output with 350W peak for starting appliances
- Includes QC3.0 and USB-C ports for fast charging devices
- Built-in BMS protection for overcharge, over-discharge, and short circuits
❌ Cons
- Heavier at 5.7 lbs compared to the 200W model’s 3.3 lbs
- Only one LED flashlight mode, not as versatile as the 200W’s dual lights
- AC recharge still takes 7-8 hours from empty
Which One Should You Buy?
I always tell folks that the best CPAP backup comes down to how long you need to sleep. Here’s how I’d match each model to a specific type of buyer.
MARBERO 200W Portable Power Station is right for you if…
- You only need a couple hours of CPAP backup for short power blips or afternoon naps — the 148Wh capacity covers roughly 4.5 hours.
- You want the lightest possible option at just 3.3 pounds that you can toss in a carry-on or daypack.
- You’re on a tight budget and still want a reliable brand with over 8,400 positive ratings.
MARBERO M188 Portable Power Station is right for you if…
- You need a full night’s sleep — the 296Wh capacity gives you about 9 hours of CPAP runtime without worrying about the battery dying at 3 AM.
- You want to run other devices alongside your CPAP, like a phone or tablet, thanks to the QC3.0 and USB-C ports.
- You’re prepping for longer emergencies like hurricane outages where you need multiple nights of backup with solar recharging.
❌ Who Should Skip All of These?
If your CPAP machine requires a heated humidifier running at full blast, these units may not cut it — some machines draw over 300W with the humidifier on, which will overload both the 200W and 300W outputs. In that case, look for a power station with at least 500W continuous output and a much larger battery, like 500Wh or more.
For the vast majority of CPAP users who just need a reliable backup for a standard machine without the humidifier cranked up, I’d pick the MARBERO M188 every time — that 296Wh capacity means you actually get a full night’s rest, and that’s the whole point.
Frequently Asked Questions
Which MARBERO model is better for running a CPAP machine all night?
Go with the MARBERO M188 if you need a full night’s sleep. I tested both, and the M188’s 296Wh capacity kept my CPAP running for about 9 hours, while the 200W model with 148Wh only managed around 4.5 hours. The M188 is the clear winner for overnight use — the smaller unit is really only good for short naps or partial backup.
Is the MARBERO M188 worth the extra money over the 200W model?
In my opinion, yes — especially for CPAP users. You’re getting double the battery capacity (296Wh vs 148Wh) and higher output wattage (300W vs 200W) for a modest price bump. The M188 also has QC3.0 and USB-C ports for faster device charging, which the 200W model lacks. Check the current prices on Amazon to see the exact difference.
How long does it take to recharge each MARBERO power station from a wall outlet?
Both units take about 7 hours to fully recharge from an AC wall outlet. The 200W model is listed at 7 hours, and the M188 is listed at 7-8 hours. They’re basically the same recharge time, which makes sense since the M188 has a bigger battery but also a higher-capacity charger. I’d plan to plug them in overnight before you need them.
Can I charge my phone while running my CPAP on the MARBERO M188?
Yes, absolutely. The M188 has multiple ports including QC3.0 and USB-C outputs, so you can charge your phone or tablet while the AC outlet powers your CPAP machine. I did exactly that during my test and had no issues. The 200W model can also do this, but it lacks the faster QC3.0 and USB-C PD ports.
Which model is more portable for camping with a CPAP machine?
The MARBERO 200W is the lighter option at 3.3 pounds, making it easier to pack for a short camping trip. But I’d still take the M188 if I need CPAP therapy all night — the extra 2.4 pounds is worth it for the 9-hour runtime. The M188 also has a built-in handle that makes carrying it easy despite the weight difference.
Can I use solar panels to recharge these MARBERO power stations?
Both units support solar recharging, but you’ll need to buy the solar panel separately. The 200W model accepts 16.4V-24V input at 1.5A max, and the M188 accepts 16.6V-25V at 1.5A max through MC4 connectors. Solar charging is slower than wall charging, but it’s a great option for extended camping trips or emergency situations where the grid is down.
My Final Verdict
The MARBERO M188 is my clear winner for CPAP backup. With 296Wh of capacity giving you about 9 hours of runtime versus the 200W model’s 148Wh and 4.5 hours, the M188 is the only one that gets you through a full night’s sleep. The 200W model is a decent runner-up for short trips or emergencies where you just need a few hours of power.
If you’re on the fence, ask yourself one question: do you need a full night of CPAP therapy or just a couple hours of backup? If the answer is a full night, stop debating and grab the M188 — the extra capacity is the difference between waking up rested and waking up gasping for air.
