on cloudy days, the charging capacity will vary depending on the clouds in the sky, but it should be able to charge anywhere from 20% and above, which will be very useful, especially in emergencies.

this solar charger is made of three nine-watt SunPower solar panels sewn into durable leather. Small pouch to store your phones while charging, thus protecting them from direct sunlight and overheating. however, if you have a long enough charging cable, it's best to move your device to a cool place. You can also easily store all your small accessories in the bag.

There are three USB ports inside the pouch, each port can supply up to 2.4A or a total of 5V/4A (depending on the direct sunlight on the solar panel), 3prosper solar charger weighs 480 grams, the whole solar charger is folded about 30mm thick. this makes it ideal to take with you while traveling, backpacking for hikes, to work or school.

to get the most out of your portable solar devices, we highly recommend pairing the 3prosper charger with a USB battery pack. for example, the 20,000 mAh power bank is fully compatible with the 3prosper 27W solar charger, which can store enough energy to charge your phone from zero to six times. Portable battery packs like this are essential because solar chargers by themselves cannot store energy or provide power during the night when the sun is out. with a power bank, you can supply power 24H a day.
