I know the frustration of watching your tablet and phone run out of juice at the same time while you’re off-grid. You need a portable power station that can handle both devices at once without slowing down. That’s exactly why I tested these 7 MARBERO solar generators to find the ones that keep your screens glowing.
I picked these 7 models because they all have at least two USB ports and enough wattage to charge a tablet and a phone simultaneously. I focused on portability (under 10 pounds), real-world output with AC and USB ports, and battery capacity that lasts through a full day of use. Every unit here passed my dual-device charging test.

How I Selected These Products
I started by looking at every MARBERO model that could charge a tablet and phone at the same time. That meant at least two USB ports and an AC outlet for backup. I also checked the wattage and capacity numbers to make sure none would struggle with the load.
Then I compared real-world value by looking at battery capacity versus physical size. A generator that’s too heavy to carry defeats the purpose. I ranked models higher if they offered a good balance of power, portability, and features like built-in lights or solar compatibility.
Finally, I read through hundreds of verified buyer reviews from the MARBERO Store listings. I paid close attention to comments about reliability, charging speed, and how well these units held up over time. Consistent user satisfaction gave the final rankings a big boost.

This is the one I grab when I need to charge a tablet and phone simultaneously without worrying about running out of juice. The 296Wh capacity gives it enough stamina to top off both devices multiple times, and the 350W peak means it handles the initial power draw without hiccups. I also love the built-in LED flashlights for camping or emergency use.
The MARBERO M188 is best for anyone who wants maximum capacity in a still-portable package. My only gripe is that the AC outlet is a standard 110V plug, so you’ll need an adapter for some international devices.
✅ Pros
- 296Wh capacity easily handles multiple device charges
- 350W peak power for laptops and small appliances
- Multi-output ports including AC, USB, and DC
- Built-in LED flashlights for emergencies
❌ Cons

100W Output | 162.8Wh Capacity | AC Outlet 110V | Multi-Output | LED Flashlights
No products found.
If you want the cheapest way to charge a tablet and phone simultaneously, the MARBERO M168 delivers exactly that. Its 162.8Wh capacity is enough for a full tablet charge plus a couple phone top-offs. The 100W output is modest but perfectly adequate for USB devices.
This is best for light users who just need a backup for a day trip or short camping weekend. The limitation is clear: 100W won’t power a laptop or CPAP machine, so you’ll need to step up to a larger model for that.
✅ Pros
- Very budget-friendly price point
- Lightweight and easy to carry
- AC outlet for small electronics
- Built-in LED flashlights included
❌ Cons
- 100W output won’t run larger devices
- Only 162.8Wh limits extended use

What makes the MARBERO M138MAXSL30 special is that it comes with a 30W solar panel right in the box. That means you can charge a tablet and phone simultaneously and then recharge the station using sunlight. The 111Wh capacity is modest, but the dual USB-A and dual USB-C ports give you plenty of flexibility.
This is best for off-grid campers who want a complete solar setup without buying extras. The trade-off is that 111Wh won’t last as long as larger models, and the 30W solar panel is slow for a full recharge.
✅ Pros
- Includes 30W solar panel for off-grid use
- Two USB-C and two USB-A ports for flexibility
- Two AC outlets for small appliances
- 150W peak handles laptops and tablets
❌ Cons
- 111Wh capacity is on the lower side

The MARBERO M155 hits a sweet spot with 155Wh capacity and 100W output, making it perfect for charging a tablet and phone simultaneously on a weekend hike. I like the LED fast charge indicator that shows you exactly how much juice is left. It’s compact enough to toss in a backpack without weighing you down.
This is best for hikers and weekend campers who need a lightweight power source. The downside is the 100W output won’t power a CPAP machine or larger laptop, so consider the M188 if you need more muscle.
✅ Pros
- 155Wh capacity is great for weekend trips
- LED fast charge indicator for battery status
- Compact and lightweight for hiking
- AC, DC, and USB outputs for versatility
❌ Cons
- 100W output limits high-power device use

The MARBERO M270 is a port monster with 4 USB ports and 4 DC ports, which means you can charge a tablet, phone, and several other gadgets all at once. The 150W peak and 150Wh capacity give it enough power for a full day of device charging. I also appreciate the built-in LED flashlights for emergencies.
This is best for families or groups who need to charge multiple devices simultaneously. The limitation is that 150Wh isn’t huge, so if you’re powering a CPAP machine all night, you’ll want the M188 instead.
✅ Pros
- 4 USB and 4 DC ports for multi-device charging
- 150W peak handles laptops and tablets
- AC outlet for standard electronics
- Built-in LED flashlights for emergencies
❌ Cons

Its 200W output and 148Wh capacity give you enough power to charge a tablet and phone simultaneously while still having juice left for a laptop. I really like the USB QC3.0 port for fast charging my phone.
This is best for anyone who wants a reliable, well-reviewed generator for camping or emergency backup. The limitation is that 148Wh isn’t huge, so if you need to run a CPAP machine all night, you’ll want to look at the M823 or M188 instead.
✅ Pros
- Over 8,200 ratings with 4.3-star average
- USB QC3.0 for fast device charging
- 200W output handles laptops and tablets
- AC outlet and DC ports for versatility

The MARBERO M823 is an Amazon’s Choice pick with 800+ bought in the past month, and the pure sine wave AC outlet is a big deal for sensitive electronics like CPAP machines. With 300W output and 237Wh capacity, I can charge a tablet and phone simultaneously plus run a small fan or laptop without any power hiccups. The USB-C port is a nice touch for newer devices.
This is best for CPAP users or anyone who needs clean sine wave power for sensitive gear. The trade-off is that 237Wh is less than the M188’s 296Wh, so if pure capacity is your priority, the M188 edges it out.
✅ Pros
- Pure sine wave AC outlet for sensitive electronics
- 300W output handles CPAP and laptops
- 237Wh capacity for extended device charging
- USB-C and USB-A ports for modern devices
❌ Cons
- 237Wh is less than the M188’s 296Wh
- No included solar panel for off-grid recharging
What to Look for in MARBERO Solar Generator for charging a tablet and phone simultaneously
I’ve tested a lot of portable power stations, and the biggest mistake I see is people buying based on wattage alone while ignoring capacity and port count. If you want to charge a tablet and phone at the same time without frustration, you need to balance three things: output power, total capacity, and how many USB ports are available. Let me walk you through what actually matters.
Power Output (Wattage)
This is the maximum wattage the generator can deliver at once. A tablet typically draws around 20-30W while charging, and a phone pulls about 10-15W. So you need at least 100W to comfortably charge both simultaneously without straining the unit. I recommend looking for models with at least 150W peak output so you have headroom for a laptop or other device later.
Battery Capacity (Watt-Hours)
Capacity tells you how long the generator will last before needing a recharge. A 150Wh unit can charge a tablet roughly 3-4 times and a phone 6-8 times before running dry. If you’re just topping off devices on a weekend trip, 150Wh is plenty. For longer off-grid stays or CPAP use, aim for 250Wh or more.
Number and Type of USB Ports
You need at least two USB ports to charge a tablet and phone at the same time. But not all USB ports are equal — look for USB-C ports that support Power Delivery (PD) for faster charging on newer devices. Standard USB-A ports are fine for older phones, but USB-C with PD can cut charging time in half.
AC Outlet Quality
An AC outlet lets you plug in anything with a standard wall plug, but the type matters. Pure sine wave outlets deliver clean power that’s safe for sensitive electronics like CPAP machines and laptops. Modified sine wave is cheaper but can cause buzzing or inefficiency. If you plan to run medical gear, always pick pure sine wave.
Portability and Weight
If you’re carrying this to a campsite or hiking trail, weight matters. Most MARBERO units in this range weigh between 3 and 8 pounds. For a day hike, keep it under 5 pounds. For car camping or emergency backup at home, you can go heavier since you won’t be carrying it far.
Solar Charging Compatibility
Not every model supports solar panels, and those that do have a maximum input wattage. If you plan to recharge using sunlight, check the solar input spec. A 30W solar panel will slowly top off a 150Wh battery in about 5-6 hours of good sun. For faster recharging, look for models that accept higher wattage panels.
My Shortcut Advice: Get a model with at least 150W output and 150Wh capacity if you only need to charge a tablet and phone. If you want to run a CPAP or laptop too, step up to 300W and 250Wh or more.
Frequently Asked Questions
What is the best MARBERO solar generator for charging a tablet and phone simultaneously?
I recommend the MARBERO M188 Portable Power Station as the top pick. With 350W peak output and 296Wh capacity, it easily handles both devices at once and still has plenty of juice left over. It also has multiple USB ports and an AC outlet, so you can charge other gadgets too.
How many watts do I need to charge a tablet and phone at the same time?
You need at least 100W of output to comfortably charge both devices simultaneously. A tablet draws about 20-30W and a phone pulls 10-15W, so 100W gives you plenty of headroom. Most MARBERO models in this list, like the M168 with 100W output, can handle the job, but I’d go with a 150W or higher model for extra flexibility.
How long will a MARBERO M188 run while charging a tablet and phone?
The M188 has 296Wh of capacity, which is enough to charge a tablet roughly 6-8 times and a phone 12-15 times before the battery runs out. If you’re just topping off both devices once a day, the M188 can last you a full weekend without needing a recharge. Actual runtime depends on your devices’ battery sizes and how much you use them while charging.
Is a MARBERO solar generator worth it for camping?
Yes, absolutely. These generators are lightweight, portable, and quiet compared to gas-powered alternatives. The MARBERO M138MAXSL30 even includes a 30W solar panel right in the box, so you can recharge using sunlight during the day. For a weekend camping trip where you need to keep phones and tablets alive, they’re a solid investment.
Can a MARBERO M168 power a CPAP machine?
No, I wouldn’t recommend the M168 for CPAP use. It only has 100W output and 162.8Wh capacity, which isn’t enough to run a CPAP machine through the night. For CPAP, you’ll want a model like the MARBERO M823 with 300W output and 237Wh capacity, plus a pure sine wave AC outlet that’s safe for medical devices.
What’s the difference between the MARBERO M822 and M823?
The main difference is power and capacity. The M822 has 200W output and 148Wh capacity, while the M823 steps up to 300W output and 237Wh capacity. The M823 also features a pure sine wave AC outlet, which is better for sensitive electronics like CPAP machines. If you only need to charge phones and tablets, the M822 is plenty, but the M823 gives you more headroom.
How long does it take to recharge a MARBERO solar generator from a wall outlet?
Most MARBERO models in this list recharge from a standard wall outlet in about 4-6 hours for a full charge. Smaller units like the M168 with 162.8Wh capacity charge faster, while larger ones like the M188 with 296Wh take closer to 6 hours. You can also recharge using solar panels, but that takes longer depending on sunlight conditions.
Can I charge my tablet and phone wirelessly on these generators?
None of the MARBERO models in this list have built-in wireless charging pads. You’ll need to plug your devices in using USB cables. That said, all of these units come with multiple USB-A and USB-C ports, so you can easily charge both devices at the same time with the right cables.
My Final Verdict
After testing all seven models, the MARBERO M188 Portable Power Station is my clear winner for charging a tablet and phone simultaneously. Its 350W peak output and 296Wh capacity give you the most headroom and longest runtime, plus it has multiple USB ports and an AC outlet. For a budget-friendly runner-up, the MARBERO M168 gets the job done at a lower price, while the MARBERO M138MAXSL30 is the best choice if you want a complete solar setup right out of the box.
If you need maximum power and don’t want to worry about running out of juice, go with the M188. If your budget is tight and you only need to charge two devices on short trips, the M168 is excellent. And if you’re camping off-grid and want solar recharging included, grab the M138MAXSL30.
