This is a perfect pocket power bank! It's compact and light enough to fit in a pocket or bag easily. With Power Delivery in and out the bank quickly charges your devices and recharges with USB C. If you have any of the pixel phones, or a Nintendo switch this is the charger you want - because otherwise you're slow charging your device on the go. With 10000mAh, you can charge your phone up to 4 times, and your switch up to twice. You can also use it to power some laptops - though obviously not at the full 45w. I have two of these power banks, and three of different sizes and brands, and this is the one I most often choose to take with me.
