4W Solar Panel Charger with 5V Output and 18650 Battery Slots

Stay powered outdoors with a 4W solar panel charger built for compatible 5V low-power devices, remote sensors, LED units, and security cameras.

It combines solar charging, 5V DC input charging, and built-in 18650 battery slots, so you can add backup power where wall outlets are unavailable. Batteries are not included, and it supports at least 1 installed battery.

This unit is designed for 5V devices only and is not supported for 12V cameras. For best results, use it in environments from -10 b0 to 50 b0 with more than 5 hours of sunlight per day.
