Technaxx TX-207 21-watt Solar Charging Case - Black

This solar charger is manufactured for camping trips or traveling to areas without power supply. The TX-207 is 2.2 lbs and has dimensions of 12.3" x 7.87" x 1.73"; it easily fits in a backpack so you can use the solar panel on the go and charge devices everywhere. Put the solar panel in a bright place with long exposure to sunlight, the best performance is achieved when the sun hits the panel at an angle of 90°; avoid shady areas. The TX-207 monocrystalline solar cell converts up to 19% of solar energy into free energy with sufficient sunlight, which is better than polycrystalline solar panels in low light conditions.
