Sandberg Solar Charger 21W 2xUSB+USB-C (420-55) combines a foldaway solar panel and a built-in power bank for charging mobile devices when mains power is not at hand. The panel has a 21 W output, and the Li-polymer battery is rated at 10000 mAh.

Three USB charging ports let you connect devices: two USB outputs and a USB-C port that supports Power Delivery input and output, up to 18 W. Pass-through charging lets the power bank charge while it supplies power to a connected device.
