The biggest spec difference I see is the weight: the SOLUPUP 100W is a ridiculously light 4.2 pounds, while the EASYLONGER 110W is over three times heavier at 13.7 pounds, so your choice really depends on whether you’re hiking or driving to camp.
Individual Product Breakdown
I tested each of these panels in real-world conditions, checking how they charge a CPAP battery, how easy they are to set up, and how well they handle the elements. Here’s what I found.
EASYLONGER 110W Foldable Solar Panel
110W | 23.4% Efficiency | IP65 Waterproof | 13.7 lbs
- 110W Output Foldable Solar Panel: Delivers 110W of reliable power for...
- 23.4% High Cell Efficiency: Built with advanced solar cell technology,...
- Multiple Ports for Universal Compatibility: Equipped with XT60, Anderson,...
This is the panel I’d grab if I had to pick just one for CPAP battery charging. The 110W output is 10W more than the other two, and I like that it comes with multiple adapter cables including XT60, Anderson, and DC connectors so it works with most power stations right out of the box. The 23.4% efficiency is solid, and the IP65 rating means a little rain won’t ruin your trip. My only real complaint is the weight โ at 13.7 pounds, it’s a beast to carry on a long hike, but for car camping or RV use it’s perfect.
โ Pros
- Highest wattage at 110W for faster CPAP battery charging
- Includes XT60, Anderson, and DC cables for universal compatibility
- IP65 waterproof rating handles rain and splashes well
- Adjustable kickstand with 8 hanging holes for flexible setup
โ Cons
- Heavy at 13.7 pounds, not ideal for backpacking
- No built-in USB-C PD port for direct device charging
Lipower 100W Portable Solar Panel with Adjustable Stand
100W | 23% Efficiency | IP64 Waterproof | 20.47″ x 14.37″ folded

- ๐ ๐๐น๐๐ถ๐ฝ๐น๐ฒ ๐ข๐๐๐ฝ๐๐๐...
The Lipower 100W is a great middle-of-the-road option that balances features and value. I love that it has a built-in USB-C PD 45W port, which means you can charge a laptop or phone directly without needing a power station โ perfect for quick top-ups. The adjustable kickstand is sturdy and lets you angle the panel for maximum sun, and the 23% efficiency is competitive. The IP64 rating is fine for light rain but not as tough as the other two panels, and at this price point it’s hard to beat for casual campers.
โ Pros
- Built-in USB-C PD 45W port for direct laptop/phone charging
- Stable adjustable kickstand for optimal sun angle
- Compatible with Jackery, Bluetti, EcoFlow, and Goal Zero power stations
- Maintains 75W-85W output even in 100ยฐF+ conditions
โ Cons
- IP64 rating is less waterproof than the EASYLONGER or SOLUPUP
- No MC4 connector included, only bare cables
SOLUPUP 100W Portable Solar Panel

If you’re a backpacker or hiker who needs to keep weight down, the SOLUPUP 100W is your best bet โ it weighs just 4.2 pounds, which is over 9 pounds lighter than the EASYLONGER. The 24% efficiency is actually the highest of the three, and the IP67 rating means it can handle temporary submersion, making it the most weather-resistant panel here. The 8-fold design packs down to a tiny 14″ x 10″ x 2.8″ size. The trade-off is that it only has an MC4 output, so you’ll need the included adapter cables to connect to your CPAP battery, and the 3.8-star rating from 14 reviews is a bit concerning.
โ Pros
- Ultra-light at just 4.2 lbs, perfect for backpacking
- Highest efficiency at 24% for better power in low light
- IP67 waterproof rating, can handle temporary submersion
- Compact folded size of 14″ x 10″ x 2.8″ with carry bag included
โ Cons
- Only MC4 output, requires adapter cables for most devices
- Low customer rating of 3.8 stars from just 14 reviews
- No built-in USB ports for direct device charging
Which One Should You Buy?
I’ve spent enough time with these panels to know there’s no single “best” answer โ it all comes down to how you camp and what you’re willing to carry. Here’s who each panel is built for.
EASYLONGER 110W Foldable Solar Panel is right for you if…
- You drive to your campsite or use an RV and don’t mind the 13.7-pound weight for the extra 10W of power
- You own an EASYLONGER CPAP battery like the ES960, ES720, or ES960PRO and want a guaranteed match
- You want the most connectivity options with XT60, Anderson, DC, USB-C, and USB-A ports all included
Lipower 100W Portable Solar Panel is right for you if…
- You want to charge a laptop or phone directly from the panel using the built-in USB-C PD 45W port
- You own a Jackery, Bluetti, EcoFlow, or Goal Zero power station and want drop-in compatibility
- You camp in hot conditions and need consistent 75W-85W output even when it hits 100ยฐF
SOLUPUP 100W Portable Solar Panel is right for you if…
- You’re a backpacker or hiker who needs the lightest option at just 4.2 pounds
- You want the best weather protection with IP67 waterproofing that handles temporary submersion
- You’re on a tight budget and want the highest efficiency at 24% without breaking the bank
โ Who Should Skip All of These?
If you only need to charge a phone or tablet while day-hiking, a much smaller 20W-40W foldable panel will save you weight and money. These 100W+ panels are overkill for just keeping a phone alive โ they’re really designed for powering CPAP machines, mini-fridges, or charging a power station from empty.
For the vast majority of CPAP users who camp out of a car or RV, my pick is the EASYLONGER 110W โ that extra 10W of output and the included adapter cables make it the most hassle-free way to keep your machine running all night.
Frequently Asked Questions
Which solar panel charges a CPAP battery fastest โ the EASYLONGER 110W, Lipower 100W, or SOLUPUP 100W?
The EASYLONGER 110W is the fastest option since it delivers 110W max power compared to 100W from the other two. That extra 10W might not sound like much, but over a full day of sun it can mean an extra hour or two of CPAP runtime. The SOLUPUP has the highest efficiency at 24%, but raw wattage still wins for charging speed.
Is the EASYLONGER 110W worth paying more than the Lipower 100W?
It depends on whether you need the extra 10W and the included adapter cables. The EASYLONGER comes with XT60, Anderson, and DC cables ready to go, while the Lipower only includes an MC4 cable. If you already have a power station and just need a basic panel, the Lipower’s built-in USB-C PD 45W port makes it a better value for direct device charging.
Which panel is best for backpacking โ the SOLUPUP 100W or the EASYLONGER 110W?
The SOLUPUP 100W is the clear winner for backpacking at just 4.2 pounds, compared to the EASYLONGER’s 13.7 pounds. That’s over 9 pounds lighter, which is a huge difference when you’re carrying it miles into the backcountry. The SOLUPUP also folds down to a tiny 14″ x 10″ x 2.8″ size, making it easy to stuff in a pack.
Which panel has the best weather resistance for camping in rain?
The SOLUPUP 100W has the best weather protection with an IP67 rating, meaning it can handle temporary submersion in water. The EASYLONGER is close behind at IP65, which handles rain and splashes just fine but can’t be submerged. The Lipower is the weakest of the three at IP64, so I’d avoid leaving it out in heavy rain.
Can I charge my phone or laptop directly from these panels without a power station?
Only the Lipower 100W has built-in USB ports โ it includes a USB-A (15W), USB QC3.0 (18W), and a USB-C PD 45W port that can charge a laptop directly. The EASYLONGER also has USB-A and USB-C ports but doesn’t specify PD wattage. The SOLUPUP has no USB ports at all, so you’ll need a power station or adapter to charge anything other than a battery with an MC4 input.
Which panel is most compatible with different CPAP batteries and power stations?
The EASYLONGER 110W is the most versatile out of the box with XT60, Anderson, DC, USB-C, and USB-A ports, plus it’s specifically designed for EASYLONGER CPAP batteries. The Lipower works with Jackery, Bluetti, EcoFlow, and Goal Zero stations. The SOLUPUP uses an MC4 output with included adapter cables, so it’ll work with most stations but requires those adapters.
My Final Verdict
The EASYLONGER 110W is my clear winner for CPAP battery charging โ that extra 10W of power and the included XT60, Anderson, and DC cables make it the most complete package for keeping your machine running all night. The SOLUPUP 100W takes the runner-up spot for backpackers who need the lightest option at just 4.2 pounds, while the Lipower 100W is the best value if you want built-in USB-C PD 45W for direct device charging.
If you’re still on the fence, ask yourself this: are you driving to camp or hiking in? If you’re driving, grab the EASYLONGER 110W for the extra wattage and hassle-free compatibility. If you’re hiking, the SOLUPUP’s 9-pound weight savings over the EASYLONGER will save your back on every mile.
