Ultra-lightweight and designed specifically for charge speed and portability, this adapter is perfect for quickly charging your high drain devices like a laptop, drone or tablet at up to 100W. Features: Ultra-lightweight and mini design makes it perfect for space saving, like when backpacking. This adapter is pocket sized and it's our most portable USB-C adapter Capable of step-up or step-down (can provide 20V output even if solar panel input is less than 20V)! Power Delivery means the latest industry standard USB-C port with the protocols to charge nearly any smartphone, or tablet. The built-in Power Delivery system on the USB-C port intuitively gauges the maximum charge rate for devices requiring up to 100W to provide enough power to charge a compatible iPhone to 50% in 30 minutes — without the fear of overloading the unit! Designed to work in the hot sun! An all-aluminum housing keeps the internal regulator cool so you can truly harness the power of the sun.
