Many people that are looking for a portable power solution are going to be better off skipping the solar charger altogether and starting with a USB battery pack. Our large battery pick will keep a smartphone charged every night for a week and is no bigger than a paperback novel. However, if you will be on the trail for more than a week, you can’t be sure of your power needs, or you want something to tuck into your emergency kit, a solar charger could refill a small battery pack in a day or directly charge a smartphone in two to three hours.
This amazing 20W Solar Charger and Power Bank feeds power directly to your device or a power bank (purchased separately), it allows you to detach your USB port from the panel up to a distance of one meter, so that you can leave it outside while charging your phone safely indoors via the USB port.
