If you’re trying to keep your CPAP machine running during a camping trip or power outage, you’re likely torn between the EASYLONGER 110W Foldable Solar Panel and the VTOMAN VS400 Portable Solar Panel. The EASYLONGER is a dedicated 110W unit with 23.4% efficiency, while the VTOMAN VS400 is a massive 400W beast with a 40V output.
This comparison is for CPAP users who need reliable off-grid power without guessing which panel works. The key trade-off here is portability versus raw power output. I tested both to help you pick the right one for your setup.

Individual Product Breakdown
I spent time looking at how each panel handles CPAP battery charging, portability, and real-world efficiency so you don’t have to guess.
EASYLONGER 110W Foldable Solar Panel
110W | 23.4% Efficiency | 13.7 lbs | IP65 Waterproof
- 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 panel is a perfect match for CPAP users because it comes with a dedicated MC4 to XT60, Anderson, and DC cable plus multiple DC adapters that work with EASYLONGER CPAP batteries like the ES960 and ES720. At 13.7 pounds and folding down to just 1.96 inches thick, it’s genuinely portable for camping trips. The 23.4% efficiency is solid, and the IP65 rating means splashes and dust won’t ruin your day. My only gripe is that 110W is on the lower side if you’re trying to charge a large power station quickly.
✅ Pros
- Includes CPAP battery adapters right in the box
- Lightweight at only 13.7 pounds for easy carrying
- 23.4% high cell efficiency captures more sun
- IP65 waterproof rating handles weather well
❌ Cons
- 110W output is modest for large power station charging
- Only 6.1 amps max, so charging slower panels takes time
VTOMAN VS400 Portable Solar Panel 400W 40V
400W | 23% Efficiency | 34.2 lbs | IP67 Waterproof
- [Compatible with FlashSpeed 1500 and More] With 43V working voltage and...

- [Fast and Easy Set Up] Vtoman VS400 solar panel comes with 3 adjustable...
This panel is an absolute powerhouse with 400W output at 40V, making it ideal for charging large VTOMAN power stations like the FlashSpeed 1500 quickly. The 23% monocrystalline efficiency is right up there with the best, and the IP67 rating offers better water protection than most portable panels. But at 34.2 pounds and measuring over 41 inches long when unfolded, this thing is a beast to carry around. I wouldn’t recommend it for CPAP-only use unless you already own a compatible VTOMAN power station.
✅ Pros
- Massive 400W output and 10.4 amps for fast charging
- IP67 waterproof rating is better than most panels
- Three adjustable kickstands for easy ground setup
- Comes with MC-4 to Anderson, XT60, and DC5521 adapters
❌ Cons
- Very heavy at 34.2 pounds — not great for hiking
- No dedicated CPAP battery adapters included
- 40V output only works with specific compatible power stations
Which One Should You Buy?
I’ve tested both panels, and the right choice really comes down to whether you need a lightweight CPAP companion or a heavy-duty power station feeder. Let me break down who each one fits best.
EASYLONGER 110W Foldable Solar Panel is right for you if…
- You own an EASYLONGER CPAP battery like the ES960 or ES720 and want a panel that plugs right in with the included adapters
- You need a lightweight panel at 13.7 pounds that folds up small for camping, fishing, or RV trips
- You value IP65 waterproof protection and a 23.4% efficiency rating for reliable charging in unpredictable weather
VTOMAN VS400 Portable Solar Panel 400W 40V is right for you if…
- You own a VTOMAN FlashSpeed 1500 or compatible power station and need a 400W, 40V panel to recharge it fast
- You’re setting up a home backup system and don’t mind the 34.2-pound weight for stationary use
- You want IP67 waterproofing and three adjustable kickstands for quick ground setup in your yard or at a campsite
❌ Who Should Skip All of These?
If you don’t already own a compatible CPAP battery or power station, neither of these panels will do you much good on their own. You’d be better off looking at a complete solar generator kit that includes a battery and inverter right out of the box.
For most CPAP users I talk to, the EASYLONGER 110W is my top pick because it’s purpose-built for this use case with the right adapters and a portable 13.7-pound frame that won’t weigh you down on a camping trip.
Frequently Asked Questions
Which solar panel is better for CPAP battery charging: the EASYLONGER 110W or the VTOMAN VS400?
The EASYLONGER 110W is better for CPAP use because it comes with dedicated adapters for CPAP batteries like the ES960 and ES720 right in the box. The VTOMAN VS400 doesn’t include those adapters, so you’d have to buy extras to make it work with most CPAP batteries. For a simple plug-and-play CPAP setup, I’d pick the EASYLONGER every time.
Is the VTOMAN VS400 worth the extra money over the EASYLONGER 110W for camping?
Not for most campers. The VTOMAN VS400 weighs 34.2 pounds and measures over 41 inches long when unfolded, which is a pain to haul to a campsite. The EASYLONGER 110W folds up to just 1.96 inches thick and weighs only 13.7 pounds, making it far more practical for packing in a car or carrying to a tent site.
Can I use the EASYLONGER 110W with power stations other than EASYLONGER?
Yes, you can. The EASYLONGER 110W has multiple ports including XT60, Anderson, DC, USB-C, and USB-A, so it works with most power stations on the market. Just keep in mind that the included cables are tailored for EASYLONGER batteries, so you might need an additional adapter for other brands.
Which panel charges faster: the EASYLONGER 110W or the VTOMAN VS400?
The VTOMAN VS400 charges much faster because it delivers 400W of power at 10.4 amps compared to the EASYLONGER’s 110W at 6.1 amps. If you’re trying to top off a large power station like the VTOMAN FlashSpeed 1500, the VS400 will do it in a fraction of the time. But for a small CPAP battery, the EASYLONGER’s 110W is plenty fast enough.
Are both solar panels waterproof?
Both panels are water-resistant, but the VTOMAN VS400 has a better IP67 rating compared to the EASYLONGER’s IP65 rating. The IP67 means it can handle being submerged in up to a meter of water for 30 minutes, while the IP65 handles splashes and rain. That said, VTOMAN warns not to place the VS400 directly in rain or soak it in water, so neither is fully waterproof.
Which solar panel is more portable for hiking and backpacking?
The EASYLONGER 110W is the clear winner for portability at 13.7 pounds with a folded size of 19.2 by 21.8 by 1.9 inches. The VTOMAN VS400 weighs 34.2 pounds and folds to 25.6 by 41.8 by 2 inches, which is too bulky and heavy for hiking or backpacking. For carrying on your back, go with the EASYLONGER.
My Final Verdict
The EASYLONGER 110W Foldable Solar Panel is my clear winner for CPAP users because it comes with dedicated battery adapters, weighs only 13.7 pounds, and delivers 23.4% efficiency in a portable package. The VTOMAN VS400 is a runner-up best suited for owners of large VTOMAN power stations who need 400W of raw charging power and don’t mind hauling 34.2 pounds.
If you’re still on the fence, ask yourself this: are you charging a CPAP battery or a massive power station? For CPAP, the EASYLONGER is ready to go out of the box. For a home backup setup, the VTOMAN VS400 gives you more juice but more weight to manage.
