If you’re trying to pick your first solar generator, the MARBERO M155 and the MARBERO M188 are two of the most popular entry-level options. The M155 is a complete kit with a 30W solar panel and a 155Wh battery, while the M188 packs a larger 296Wh capacity but doesn’t include a panel.
This comparison is for anyone who wants a simple, affordable way to keep phones and small devices running during a blackout or camping trip. The main trade-off is portability and an all-in-one kit versus having more battery capacity to run bigger gear. Let me break down which one fits your life better.

I really like the M155 because it’s a true all-in-one starter kit that includes both the power station and a 30W solar panel right out of the box. It weighs only 3.7 pounds, which makes it the lightest option here, and the intelligent LCD display shows you exactly how much battery is left. The QC 3.0 USB port charges phones up to 4x faster than standard ports, which is a nice bonus when you’re off-grid. Just keep in mind the AC output is limited to 100W rated (150W peak), so it’s best for small electronics like phones, tablets, and fans — not power tools or a mini fridge.
✅ Pros
- Ultra-light at just 3.7 lbs, easy to carry anywhere
- 30W solar panel included with 23% conversion efficiency
- Charges phones 4x faster with QC 3.0 USB port
- Whisper-quiet silent fan operation
❌ Cons
- AC output limited to 100W, won’t run larger appliances
- 155Wh capacity is on the smaller side for longer trips

The M188 is the one I’d grab if I needed more juice for longer trips or emergencies. With 296Wh of capacity, it can fully charge a phone 25 times or run a CPAP machine for about 9 hours, which is a huge step up from the M155. It also has a built-in white LED flashlight with SOS mode, which is a thoughtful touch for power outages or camping. The downside is it doesn’t come with a solar panel, so you’ll need to buy one separately if you want to recharge from the sun.
✅ Pros
- 296Wh capacity runs a CPAP for 9 hours or charges a phone 25 times
- 350W peak AC output can handle more devices than the M155
- Built-in LED flashlight with steady and SOS modes
- Weighs only 5.7 lbs with a compact handle for easy carrying
❌ Cons
- Solar panel not included, must buy separately
- Slightly heavier at 5.7 lbs compared to the M155
Which One Should You Buy?
I’ve spent a lot of time with both of these, and honestly, the right pick comes down to whether you want a grab-and-go kit or more battery capacity for longer trips. Let me match you to the perfect one.
MARBERO M155 Solar Generator with 30W Panel is right for you if…
- You want a complete all-in-one kit with a solar panel included so you can start using it right away
- You need something ultra-light at just 3.7 lbs for backpacking, hiking, or tossing in a car trunk
- You only need to charge small electronics like phones, tablets, and fans — the 100W AC output is plenty for that
MARBERO M188 Portable Power Station 296Wh is right for you if…
- You need enough juice to run a CPAP machine for about 9 hours or charge a laptop 4 times
- You’re preparing for longer emergencies or hurricane season and want the extra 296Wh capacity
- You already own a solar panel or don’t mind buying one separately for recharging
❌ Who Should Skip All of These?
If you need to run power tools, a full-size refrigerator, or anything over 350W, neither of these will cut it. You’d be better off looking at a larger portable power station with at least 500Wh capacity and a higher wattage inverter.
For most beginners just wanting to keep phones, tablets, a laptop, or a small fan running during a blackout or camping trip, I’d grab the MARBERO M155 kit. It’s the simplest way to get started with solar power without buying anything extra.
Frequently Asked Questions
Which is better for camping, the MARBERO M155 or M188?
I’d pick the M188 if you’re camping for more than one night, since its 296Wh capacity will keep your phone charged and run a small fan much longer than the M155’s 155Wh. But if you’re a lightweight backpacker who wants to save every ounce, the M155 is way easier to carry at just 3.7 pounds and includes the solar panel so you can recharge during the day. For most car camping trips, the M188’s extra battery life wins for me.
Is the MARBERO M188 worth the extra money over the M155?
In my opinion, yes — if you need the extra runtime. The M188 has nearly double the capacity (296Wh vs 155Wh) and a higher AC output (300W rated vs 100W rated), which means it can power a CPAP machine for about 9 hours or a mini fridge for roughly 10 hours. The M155 is cheaper and comes with a solar panel, but you’re paying for a much smaller battery that won’t stretch as far.
Can the MARBERO M155 charge a laptop?
Yes, it can, as long as your laptop draws less than 100W. The M155 has a QC3.0 USB port and standard USB-A ports, but for most laptops you’ll want to use the AC outlet. The M188 is a better bet for laptops since it has a USB-C port with QC3.0 support and a higher 300W AC output that handles bigger laptops without issue.
How long does it take to recharge each one from a wall outlet?
The M155 takes about 6 hours to fully recharge from a standard wall outlet using the included 115V/2A adapter. The M188 takes a bit longer at around 7-8 hours because its battery is nearly twice as large. If you’re in a hurry, both support solar charging too — the M155 comes with a 30W panel that also takes about 6-7 hours in direct sun.
Which one is better for a power outage or hurricane emergency?
I’d go with the M188 for emergencies without hesitation. Its 296Wh capacity can run a CPAP machine for 9 hours or keep a phone charged 25 times, which is critical when the power might be out for days. The M155 is still useful for keeping a phone and a small light going, but you’ll run out of juice much faster. The M188 also has a built-in LED flashlight with SOS mode, which is a nice safety feature during a blackout.
Does the MARBERO M188 come with a solar panel?
No, it does not — the M188 is sold as just the power station, so you’ll need to buy a solar panel separately if you want to recharge from the sun. It does include MC4 solar connectors so you can hook up any compatible panel. The M155 is the better pick if you want everything in one box, since it includes a 30W foldable solar panel right in the package.
My Final Verdict
If you’re a beginner just getting into solar generators, the MARBERO M155 is my clear winner. It gives you a complete, ready-to-use kit with a 30W solar panel and a 155Wh power station that weighs only 3.7 lbs, so you can start charging devices right out of the box without buying anything extra. The M188 is a better pick if you already have a solar panel or need the extra 296Wh capacity to run a CPAP machine for 9 hours.
Still on the fence? Ask yourself this: do you want to open one box and be ready to go, or do you need more battery life for longer trips? The M155 is the easiest way to start, while the M188 is the upgrade for when you outgrow it.
