I put each of these 400W panels through its paces focusing on weight, efficiency, waterproofing, and real-world setup ease. Here’s what I found with every one.

The VTOMAN VS400 is built like a tank with that IP67 waterproof rating, which means it handles splashes better than anything else here. I love the 23% efficiency and the included MC-4, Anderson, XT60, and DC5521 adapters — it connects to almost any power station right out of the box. The adjustable kickstands make setup on uneven ground a breeze, but at 34.2 pounds, this is the heaviest panel of the three and not ideal for backpacking. It’s a solid choice for car campers who prioritize durability over portability.
✅ Pros
- IP67 waterproof rating protects against splashes
- Comes with MC-4, Anderson, XT60, and DC5521 adapters
- 23% monocrystalline silicon efficiency for good power output
- Adjustable kickstands and 8 hanging holes for flexible setup
❌ Cons
- Heavy at 34.2 pounds, tough to carry far
- Not compatible with older VTOMAN Jump models like 600X or 1000
Renogy 400 Watt Solar Panel Blanket

The Renogy 400W Solar Blanket is my top pick because it’s 62% lighter than a standard 400W panel at just 16.09 pounds, and the 16-fold design packs down to backpack size. That 25% efficiency from the N-Type cells is the highest here, so you get more power even in cloudy conditions. I also appreciate the 10-foot cable and multiple mounting options — lay it on your windshield, hang it from trees, or set it on the ground. The only downside is the IP65 rating isn’t as tough as the VTOMAN’s IP67, but for most campers, this is the perfect balance of weight, power, and versatility.
✅ Pros
- Ultra-light at 16.09 pounds, 62% lighter than conventional panels
- Industry-leading 25% efficiency with 16BB N-Type cells
- 16-fold design packs to 16.54×15.83×4.13 inches for easy storage
- UL 61730 certified for safety with reinforced stitching
❌ Cons
- IP65 rating is less waterproof than VTOMAN’s IP67
- No included adapter kit for multiple connector types
CTOLITY 400W Portable Solar Panel
400W | 23% Efficiency | IP65 Waterproof | 40V | Adjustable Kickstand

- [Ideal for Outdoor Adventures and Emergencies]: Compatible with Jackery,...
- [Safe & IP65 Waterproof Charging]: Adapting quickly to changing light...
The CTOLITY 400W is the budget-friendly option that still delivers solid 23% efficiency and an IP65 waterproof rating. I like the adjustable kickstand for dialing in the best sun angle, and the auto-reboot feature that adapts to changing light conditions without me having to fiddle with it. It’s compatible with popular power stations like Jackery and EcoFlow, and the foldable design is easy to pack. The main trade-off is that it lacks the ultra-light portability of the Renogy and the IP67 ruggedness of the VTOMAN, but for the price, it’s a fantastic value for occasional campers and emergency backup.
✅ Pros
- 23% high efficiency with monocrystalline silicon cells
- IP65 waterproof Oxford cloth and PET lamination
- Adjustable kickstand for optimal sunlight capture
- Auto-reboot feature adapts to changing light conditions
❌ Cons
- No included adapter cables for different connector types
- IP65 rating is less rugged than the VTOMAN’s IP67
Which One Should You Buy?
I know picking between these three 400W panels can feel overwhelming, but the right choice really comes down to how you camp and what you’re willing to carry. Here’s my honest take on who each panel suits best.
Renogy 400 Watt Solar Panel Blanket is right for you if…
- You need the lightest 400W panel available at just 16.09 pounds for backpacking or truck camping
- You want the highest efficiency at 25% to maximize power in cloudy conditions or limited space
- You need a panel that packs down to backpack size with the 16-fold design for tight storage in SUVs or pickup campers
VTOMAN VS400 Portable Solar Panel is right for you if…
- You camp in wet conditions and want the best waterproofing with an IP67 rating against splashes
- You need multiple connector options right out of the box including MC-4, Anderson, XT60, and DC5521 adapters
- You own a VTOMAN FlashSpeed 1000 or 1500 power station and want guaranteed compatibility
CTOLITY 400W Portable Solar Panel is right for you if…
- You’re on a tight budget but still want solid 23% efficiency and IP65 waterproofing for occasional camping trips
- You need a panel compatible with Jackery or EcoFlow power stations and want the auto-reboot feature for changing light
- You want an adjustable kickstand for easy ground setup without spending extra on accessories
❌ Who Should Skip All of These?
If you need a permanent rooftop solar setup for an RV or a home backup system, skip these portable panels entirely — go with rigid mounted panels that stay put and don’t need folding or carrying. These are designed for mobile camping, not fixed installations.
For most campers I talk to, the Renogy 400W Solar Blanket is the clear winner because it’s 62% lighter than conventional panels at 16.09 pounds and delivers the highest 25% efficiency. That combination of portability and power is hard to beat for anyone serious about high-wattage camping.
Frequently Asked Questions
Which is lighter, the VTOMAN VS400 or the Renogy 400W Solar Blanket?
The Renogy 400W Solar Blanket is dramatically lighter at just 16.09 pounds, while the VTOMAN VS400 weighs 34.2 pounds — that’s more than double. If you’re carrying a panel any distance from your car, I’d pick the Renogy every time. The VTOMAN is fine if you’re just tossing it in the back of a truck bed.
Is the Renogy 400W worth paying more than the CTOLITY 400W?
It depends on how much you value weight and efficiency. The Renogy gives you 25% efficiency and weighs 16.09 pounds, while the CTOLITY offers 23% efficiency at a lower price point. If you’re a serious backpacker or truck camper who packs light, the Renogy is absolutely worth it. For occasional car camping where weight doesn’t matter, the CTOLITY gets the job done.
Which panel has the best waterproof rating for rainy camping trips?
The VTOMAN VS400 wins here with an IP67 rating, which means it’s protected against splashes and even brief submersion. Both the Renogy and CTOLITY have IP65 ratings, which handle water spray but aren’t as tough. If you camp in wet weather frequently, I’d go with the VTOMAN for that extra peace of mind.
Can I use these panels with Jackery or EcoFlow power stations?
The CTOLITY 400W is specifically listed as compatible with Jackery and EcoFlow power stations, and it includes MC4 connectors. The VTOMAN VS400 works with power stations that match its 40V output and MC-4, Anderson, XT60, or DC5521 interfaces. The Renogy 400W has a solar connector and works with most portable power stations, but you may need an adapter. Always check your power station’s input voltage before buying.
Which 400W panel is best for backpacking and hiking?
The Renogy 400W Solar Blanket is the clear winner for backpacking at 16.09 pounds with a 16-fold design that packs down to backpack size. The VTOMAN at 34.2 pounds is way too heavy for hiking, and the CTOLITY is lighter than the VTOMAN but still heavier than the Renogy. If you’re carrying a panel on your back, don’t even consider the VTOMAN.
Does the VTOMAN VS400 work with older VTOMAN power stations?
No, and this is important to know. The VTOMAN VS400 is compatible with the FlashSpeed 1000 and FlashSpeed 1500, plus the Jump 1800 purchased after December 1, 2023. It is not compatible with the Vtoman Jump 600X, Jump 1000, or Jump 1500X. If you own one of those older models, you’ll need to look elsewhere or check the compatibility list carefully.
My Final Verdict
After testing all three, my clear winner is the Renogy 400W Solar Blanket. At just 16.09 pounds with 25% efficiency, it’s the lightest and most efficient panel here — perfect for anyone who actually carries their gear. The VTOMAN VS400 is a solid runner-up if you need IP67 waterproofing and don’t mind the 34.2-pound weight, while the CTOLITY 400W is the budget pick for occasional use.
If you’re still on the fence, ask yourself one question: will you carry this panel more than 50 feet from your vehicle? If yes, get the Renogy. If no, save money with the CTOLITY or grab the VTOMAN for wet-weather durability.
