I picked up the 45-Watt USB-C Charger to cut down recharge times on my Sherpa 100PD, and it does exactly that. The USB-C PD output covers 5V up to 20V at 3A, so my power bank tops up noticeably faster than with the stock wall adapter. It's compact at 2.4 x 2.4 x 1.2 in and light at 4.48 oz, so it lives in my bag without adding bulk. The extra USB-A port at 12W is handy for a phone. Only reason it's not five stars is that 45W max is the ceiling, so it won't fast-charge bigger laptops.
