20W Flexible Solar Panel Kit for 12V Batteries and USB Devices

Product Overview

Build a compact daylight charging setup with this 20W flexible solar panel kit. The monocrystalline panel operates at 18V and measures 425 × 250mm, with an approximate net weight of 285g. Its flexible body and corner eyelets help with placement around a parked vehicle or outdoor charging area.

The kit combines a battery connection lead with a separate dual USB adapter. Choose the appropriate connection for the load: the battery circuit uses the panel output, while the adapter supplies regulated 5V USB power.

Package Contents

Includes one 20W solar panel, one approximately 1.5m battery-clip lead, one dual USB car adapter, one approximately 1.5m cigarette-socket lead and one DC female-to-two-male splitter. Two cell layouts are supplied at random; they are not a two-panel set. Phones and other example devices are excluded.

Key Features

• 20W peak monocrystalline panel with approximately 19.5% conversion efficiency.

Compatibility & Notes

Match the charging arrangement to the voltage and chemistry of your 12V battery, including an appropriate controller when required. Reverse-current protection is not overcharge protection, and the kit does not include a controller or battery.

Check polarity and whether the vehicle socket permits battery charging before connecting it. Keep the panel unshaded, avoid sharp creases, and protect connectors from water. Actual current varies with sunlight and load; the two USB ports do not each provide the full panel wattage.
