E15 · Portable solar charging
A compact solar charger for your next stop.
Bring daylight charging along on hikes, camping trips and outdoor breaks. The FlexSolar E15 pairs a 15W folding monocrystalline solar panel with a USB-A output for compatible phones, power banks and small USB essentials.
Made for everyday use
A closer look.
A familiar USB connection
The USB-A output is rated at 5V / 3A max. Use a suitable charging cable for a compatible phone, power bank or USB accessory. Charging performance depends on both the available sunlight and the device's input requirements.
Fold it into your travel kit
The panel folds to 212 × 189 × 18 mm for storage and opens to 569 × 212 × 3 mm. Its folding design lets you pack the solar surface away between sunny stops.
Choose a clear view of the sun
Four attachment points and two included carabiners offer placement options. Fully unfold the panel in a stable, unshaded position when charging; keep the connected device shaded and ventilated.
A sunny break on the trail
Set up the panel while you pause to rest, and use the daylight to top up a compatible phone or power bank.
Small essentials at camp
Keep a solar charging option with your outdoor kit for compatible USB lights, fans and other small rechargeable devices.
Check the input requirement
Choose devices that accept 5V USB power and use a compatible cable. A USB-A port can work with a device-side USB-C, Micro-USB or Lightning cable when the device's charging requirements are met. The connector alone does not establish compatibility.
Included accessories
E15 solar panel, two carabiners and a USB-A male to USB-C female adapter.

Before you get started
A few useful answers.
Will it charge without sunlight?
Solar charging needs available light. Direct, unobstructed sunlight provides better conditions than shade or charging through glass.
Does the wattage guarantee a charging speed?
No. 15W is the panel rating under standard test conditions. Device requirements and outdoor conditions determine actual charging output.
Can it charge a laptop?
Check the laptop input first. Many laptops require higher-voltage charging that a 5V USB-A charger does not provide.
How should I position my phone?
Keep the solar panel in sunlight and the phone shaded and ventilated. Check the phone to confirm that charging has started.
