The PT Flap 21W SunPower is a new generation portable and foldable solar charger uses flexible solar cells with very high efficiency (> 20%). It is the first charger in the world to integrate a triple 5V & 12V output as well as MPPT electronics (Maximum Point of Power Tracking) which optimizes the voltage drops of the panel during cloudy periods and thus its efficiency: 3000mA at 5V in USB-C and 1200 mA at 12V for less than 700g! It transforms light directly into 5V / 12V electricity and charges most devices equipped with a USB charger cable (smartphones, GPS running watches, Sport Camera, Powerbank, 12V batteries, etc.) in a few hours. Ultra-flat in shape (4mm), its encapsulation in a high-quality ETFE material optimizes its performance in high heat and extends its resistance to wear. The Flap 21W is the solar station for adventurers who want total autonomy!
