E40PRO · 40W FOLDABLE SOLAR CHARGER
More ways to connect your outdoor essentials.
The E40PRO brings USB-A, USB-C and a 19V DC output together in a foldable 40W solar charger. At 750g, it is easy to add to a travel kit when you want connection options for compatible USB electronics and small devices with a matching DC input.
Made for everyday use
A closer look.
Choose USB or a matching DC input
Use USB-A or USB-C for compatible portable electronics, or the 5.5 × 2.1 mm DC connection for equipment that accepts 19V input. Check the device's electrical requirements before connecting; a plug that fits is only one part of compatibility.
Up to 18W through USB-A
The QC3.0 USB-A output supports 5V/3A, 9V/2A and 12V/1.5A profiles, up to 18W. Supported devices can use the appropriate profile, subject to the sunlight available. The panel's 40W rating should not be read as 40W from every output.
750g of foldable solar charging
The monocrystalline panel opens to 1142 × 250 mm and folds for transport between campsites or travel stops. Two included carabiners provide attachment options. For charging, open the panel completely and give the full solar surface a clear view of direct sunlight.
A mixed camping kit
Bring one panel for compatible USB gear and a small power station whose solar input matches the panel's 19V DC output.
Daylight charging on a trip
Set it up during a sunny break to charge a phone or power bank before packing it away for the next stop.
Check both the connection and the input rating
For DC use, confirm the device accepts 19V and matches the 5.5 × 2.1 mm plug, polarity and input limits. Use a suitable cable for USB devices. USB-C compatibility and charging speed depend on the connected device; the 40W panel rating is not a per-port guarantee.

Before you get started
A few useful answers.
Does this panel store energy?
No. It supplies solar energy in real time. Use a compatible power bank or power station if you need to store energy for later.
Can I use DC and USB at the same time?
Use either DC or USB charging for the intended setup. The current product guidance advises against combining DC and USB outputs.
Will it work with any small power station?
No. Check the station's accepted voltage range, current and power limits, connector and polarity against the panel's DC output.
Is the junction box waterproof?
No. Keep the junction box, ports, cable connections and connected devices dry when using the panel outdoors.
