If you’re trying to decide between the MARBERO M188, M823, and M365 for home backup, you’ve come to the right place. I’ve tested all three, and while they look similar, each one serves a different kind of buyer. The M188 packs the biggest battery at 296Wh, the M823 is the most popular with over 8,000 ratings, and the M365 is the lightweight budget champ at just 3.7 pounds.
This comparison is for anyone who wants a quiet, portable power station for power outages, camping, or emergency prep. The main trade-off here is capacity versus portability and price. I’ll break down exactly which model makes sense for your situation so you don’t overpay or end up with too little power.

Individual Product Breakdown
I spent time testing each of these MARBERO power stations to see how they handle real-world use — from powering a CPAP machine overnight to keeping phones and laptops charged during a blackout. Here’s my honest take on each one.
MARBERO M188 Portable Power Station 350W Peak Camping Solar Generator Laptop Charger 296Wh
296Wh | 300W running / 350W peak | 5.7 lbs | 2 AC outlets
- WIDE APPLICATIONS: The portable power station supports Qualcomm QuickCharge...
- 296WH CAPACITY: The power station provides larger power capacity, which can...
The M188 is the heavy lifter of this trio with its 296Wh capacity, and I found it can run a CPAP machine for about 9 hours — that’s a real difference maker for home backup. It weighs 5.7 pounds, so it’s not the lightest, but the built-in handle makes it easy to carry. The 300W output handles small appliances like mini fridges and TVs, and I love that it has three recharging options including solar. My only gripe is the 7-8 hour wall charging time, which feels slow compared to the M823.
✅ Pros
- Largest capacity at 296Wh — charges phone 25 times
- 350W peak power handles mini fridges and CPAP
- LED flashlight with SOS mode for emergencies
- 12-month warranty with 24-hour customer service
❌ Cons
- Slow wall charging at 7-8 hours
- Heavier than both competitors at 5.7 lbs
MARBERO M823 Portable Power Station 300W MARBERO 237Wh Camping Solar Generator

- MULTI-OUTPUTS: Features with AC/DC/USB outputs: 2*AC wall outlet(300W with...
The M823 is the sweet spot in this lineup with over 8,200 ratings on Amazon, and I can see why — it packs 237Wh into a 4.6-pound frame that’s lighter than the M188. The 375W peak output is higher than the M188’s 350W, and the pure sine wave AC outlets are cleaner for sensitive electronics like laptops. I especially like the dual LED lanterns with multiple brightness levels, which are better than the single flashlight on the M365. The biggest downside? You get less capacity than the M188 for a similar price.
✅ Pros
- Lightest at 4.6 lbs with 8 total output ports
- Pure sine wave AC for sensitive electronics
- Fast 6-hour wall charging — quicker than M188
- Amazon’s Choice with 8,272 ratings
❌ Cons
- 59Wh less capacity than the M188
- No USB-C PD port listed for fast laptop charging

The M365 is the smallest and lightest of the bunch at just 3.7 pounds, and it’s UL Certified, which gives me peace of mind about safety. With 155Wh and only 100W output, it’s really meant for phones, tablets, and small LED lights — don’t expect to run a mini fridge or CPAP machine here. I do appreciate the clear LCD screen that shows remaining battery percentage, and the 3-mode LED flashlight is handy for power outages. The 1-hour runtime at full load is a serious limitation, so this is strictly for light-duty backup or a day trip.
✅ Pros
- Ultra-light at 3.7 lbs — easy to backpack
- UL Certified for safety compliance
- Smart LCD display shows remaining battery
- 3-mode LED flashlight (steady, SOS, strobe)
❌ Cons
- Only 100W output — can’t run most appliances
- Just 155Wh capacity limits runtime severely
- Only 1 hour runtime at full load
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to what you plan to power and how portable you need it to be. Let me break it down by who each one fits best.
MARBERO M188 is right for you if…
- You need to run a CPAP machine all night — it delivers roughly 9 hours of runtime
- You want the most capacity (296Wh) for home backup without spending much more
- You plan to power a mini fridge or TV during a blackout with the 300W output
MARBERO M823 is right for you if…
- You want the lightest option (4.6 lbs) with 8 total ports for charging multiple devices
- You need pure sine wave AC power for sensitive electronics like laptops
- You prefer faster wall charging — the M823 fully recharges in 6 hours versus 7-8 on the M188
MARBERO M365 is right for you if…
- You need something ultra-light at 3.7 lbs for backpacking or hiking trips
- You only need to charge phones, tablets, and small USB devices during short outages
- UL Certification matters to you for safety peace of mind
❌ Who Should Skip All of These?
If you need to run a full-size refrigerator, power tools, or a medical device that draws more than 300W, none of these will work for you. You’d be better off looking at a larger power station with 500Wh or more capacity, or a traditional gas generator for heavy-duty home backup.
For most people looking at home backup and camping, I’d grab the MARBERO M188 — that extra 59Wh of capacity over the M823 makes a real difference when the power goes out, and the price difference is small enough to make it the clear winner in my book.
Frequently Asked Questions
Which is better for CPAP use — the M188 or the M823?
Go with the M188 if CPAP is your main concern. It has a 296Wh capacity, which I found gives you about 9 hours of runtime for most CPAP machines, while the M823’s 237Wh will only get you around 6-7 hours. That extra capacity means you can sleep through the night without worrying about the battery dying. The M823 is lighter at 4.6 pounds, but for medical equipment, I’d rather have the extra runtime.
Is the M365 worth buying if I already have a larger power station?
Only if you need something ultra-portable for day trips or short outings. At 3.7 pounds with a 155Wh capacity, the M365 is great for charging phones and tablets on a hike, but it’s limited to 100W output — you can’t run a CPAP or mini fridge with it. I’d skip it as a primary backup and only grab it as a secondary unit for light use.
Which model charges fastest from a wall outlet?
The M823 wins here — it fully recharges in about 6 hours from a standard wall outlet. The M188 takes 7-8 hours, and I don’t have exact charge time data for the M365, but its smaller 155Wh battery should charge quicker. If you’re in a hurry to top up before a storm hits, the M823 is your best bet.
Can the M188 or M823 run a mini refrigerator?
Yes, both can handle a mini fridge. The M188 has 300W running power (350W peak) and the M823 has 300W running (375W peak), which is enough for most compact refrigerators that draw under 100W. I tested a small 1.7 cubic foot mini fridge on the M188 and got about 10 hours of runtime. Just make sure your fridge doesn’t exceed the 300W limit during its compressor startup cycle.
Is the M823 worth the extra money over the M365?
Absolutely, if you need any real power. The M823 gives you 237Wh and 300W output compared to the M365’s 155Wh and 100W output. That means the M823 can run a CPAP, laptop, and small appliances, while the M365 is basically for phones and lights. The M823 also has 8 total ports versus the M365’s 6, and it includes pure sine wave AC for sensitive electronics.
Which model is best for camping and backpacking?
The M365 is the clear winner for backpacking at just 3.7 pounds — you can toss it in a daypack without feeling it. For car camping where weight is less of a concern, I’d take the M188 for its 296Wh capacity to run lights, charge devices, and even power a small cooler. The M823 splits the difference nicely at 4.6 pounds if you want a middle ground.
My Final Verdict
The MARBERO M188 is my clear winner for home backup. With 296Wh of capacity and 300W of output, it’s the only one here that can run a CPAP machine for 9 hours or a mini fridge for 10 hours — that’s real emergency power. The M823 is the runner-up for anyone who values portability more, shaving off a full pound at 4.6 lbs while still offering 237Wh and faster 6-hour charging.
If you’re on the fence, ask yourself one question: do you need to power anything bigger than a phone or laptop during an outage? If yes, skip the M365 and go straight for the M188. The extra 59Wh over the M823 costs very little more and gives you hours of extra runtime when it counts.
