Shargeek's see-through 130W Storm 2 Slim is my new favorite power bank

The Shargeek Storm 2 Slim is a unique power bank with a see-through design that looks stunning and a built-in screen that shows real-time charging details. Throw in a 20000mAh battery and 130W over USB PD, and you get a fantastic portable power bank.
