Design and build

The panel balances portability with functionality in a foldable format that’s easy to carry and set up. The monocrystalline cells provide a sleek black finish and high efficiency for their size.

Foldability and portability

You’ll appreciate its compact folded dimensions and light weight, which make it simple to pack into a backpack or stash in a van. When unfolded, it gives a larger surface area for sunlight without being too bulky to handle on your own.

Weather resistance and durability

The surface is water-resistant and designed for outdoor use, which means light rain or splashes won’t immediately ruin it. That said, water-resistant is not the same as fully waterproof, so you should avoid prolonged exposure to heavy rain and store it dry when not in use.

Compatibility and outputs

One of the standout features is the included 10 DC adapters, meaning you can pair this panel with most portable power stations and solar generators on the market. That flexibility reduces the guesswork when matching connectors.

Ports explained

You get three output options: a dedicated 18V DC output (up to 2.27A), a USB Type-C port, and a USB QC3.0 port. The DC output is mainly for power stations and larger devices, while USB-C and QC3.0 cover phones, tablets, power banks, cameras, and smaller electronics.

10 DC adapters and power station compatibility

The 10-in-1 connector set is a big convenience; it means you won’t need additional adapters for most power stations. If you already own a portable generator, there’s a good chance this panel will plug right in via one of the included tips.

Performance and charging

With a conversion efficiency up to 22%, this panel can produce a decent amount of power relative to its size when conditions are good. Real-world output depends heavily on sunlight intensity and panel orientation.

Solar efficiency and power under conditions

Under ideal sun (roughly the product’s recommended conditions above 40,000 Lux), you’ll see near the 40W rating on a clear, sunny day at midday. On partly cloudy days or when the panel is not optimally angled, output drops noticeably — that’s normal for small portable panels.

Real-world charging tests

Phone: Using the QC3.0 or USB-C port, you’ll see fast charging for many phones, especially those that support Quick Charge. In full sun, an average smartphone can get a meaningful charge within an hour or two.
Tablet/iPad: Tablets draw more power; USB-C is the better choice if your iPad supports higher input. Charging is slower than a wall adapter but reliable if the sun is strong and steady.
Laptop: Charging a laptop depends on the laptop’s power requirements and whether your laptop supports USB-C charging at the panel’s available wattage. Many laptops need 30W–65W; this 40W panel can top up small or low-power laptops in good sun but may not sustain full-speed operation on power-hungry models.
Portable power station: With the DC 18V connection and the right adapter, you can trickle-charge many small power stations; charge times will vary by battery capacity. Expect slow-but-steady input rates that are best for topping up rather than rapid charging.
Small refrigerator or appliances: The panel can help run or extend the run-time of very small 12V devices in bright sun, but it’s not suitable as the sole power source for high-draw appliances long-term.

Setup and first use

Getting started is straightforward: unfold the panel, face it toward direct sunlight, and connect using the appropriate cable or adapter. Make sure the connectors are securely seated before relying on the panel to charge a device.

How to connect to a portable power station

Unfold the panel and lay it flat or prop it up at an angle to the sun.
Pick the DC adapter tip that matches your power station’s input.
Connect the DC-to-DC cable from the panel to the selected tip.
Plug the adapter into your power station’s solar input and check input indication on the station.
Adjust panel angle for best sunlight and monitor charging.

How to charge devices directly

Choose the correct output port (USB-C for modern devices, USB QC3.0 for fast charge phones, DC for devices needing 18V).
Use your device’s cable to connect to the panel’s USB port or use the included DC cable and tips for other devices.
Place the panel in direct sun with minimal shade.
Check your device for charging indicators — if there’s no response, try repositioning or using another port.

Tips for maximizing power

A few small habits can significantly boost the panel’s daily energy harvest and make charging faster and more dependable. You’ll want to be mindful of angle, shade, and cleanliness.

Best sun positioning and angle

Point the panel toward the sun and angle it perpendicular to the incoming rays for the best output. In general, adjust the tilt based on your latitude and the time of day; a quick re-angle during long sessions can increase energy capture by a sizable margin.

Managing heat and power tracking

Solar panels are less efficient when hot; allow airflow behind the panel to keep temperatures lower. If you have a portable power station with MPPT or advanced solar tracking, pairing it with this panel will improve charge efficiency compared to a basic controller.

Safety and smart charging

You get built-in protections thanks to TIR-C technology, which helps the panel identify devices and prevent overcharging or overcurrent. That makes it safer to leave devices connected while you tend to other tasks around camp.

TIR-C tech and protections

TIR-C helps the panel manage charging profiles and shield connected gear from typical electrical risks like overloading and short-circuiting. You’ll still want to use good-quality cables and avoid forcing mismatched connectors.

Safe handling and maintenance

Avoid leaving the panel in extreme weather, and don’t place heavy objects on the solar cells. When unplugging, pull from the connector rather than yanking the cable to preserve ports and wiring.

Portability and packing

Weighing about 3.3 pounds and folding down to a compact size, you can easily carry this panel in a daypack or tuck it into a small storage area in your vehicle. Its size makes it attractive for short trips where you want supplemental power without a heavy solar setup.

Weight and folded size specifics

At 12.6 x 9.1 x 2 inches folded and 1.5 kg, it’s lighter and more compact than many 40W options that use rigid backing. You’ll find it easy to handle solo and convenient to store with your other outdoor gear.

What fits in a backpack/van

You can slide it into most medium-sized backpacks or sling it in a van overhead or under a seat. Because it folds, it won’t snag gear the way a rigid panel might, and you can often fit it alongside clothing and electronics.

Accessories and included items

The package gives you the basics to get started, which reduces initial accessory purchases. Still, there are optional extras that can improve convenience.

Troubleshooting common issues

If you run into problems, many are fixable with simple checks and adjustments. Below are the most common issues and how you can handle them.

Not generating expected power

Check for shade, even small shadows from leaves or your body can reduce performance.
Re-angle the panel to face direct sun and ensure it’s perpendicular to the sun’s rays for best output.
Confirm the connectors are fully seated and the cable isn’t damaged.
If it’s early morning or late afternoon, remember the sun angle reduces output relative to midday.

Device not charging or charging slowly

Try a different port (USB-C vs QC3.0) to see if one works better for your device.
Use your device’s original charging cable where possible — generic cables can limit current.
Check that the correct DC tip is being used for power stations; mismatches can prevent charging.
If the device needs more wattage than the panel can provide, the panel may only trickle charge or not register as charging.

Maintenance and care

Proper care prolongs the life and maintains the performance of your solar panel, especially since it’s meant for outdoor use.

Cleaning and storage

Clean the solar surface with a soft cloth and mild, soapy water to remove dirt and debris; avoid abrasive cleaners. Store folded in a dry place, and don’t keep it folded wet for long periods.

Long-term care and lifespan

Avoid dropping or bending the panel excessively; repeated stress can damage cells or wiring. With normal use and care, the panel should provide years of service, though solar cell output slowly declines over time like all panels.
