I picked up this 65-Watt USB-C Charger to cut down the recharge time on my Sherpa 100AC, and it does exactly that. The USB-C PD output hits 20V at up to 3.25A, so it maxes out at 65W, and the extra USB-A port (12W) is handy for a phone at the same time. It's compact at 2.4 x 2.4 x 1.2 in. and only 4.48 oz, so it lives in my bag. Build feels solid and it works with my tablet and laptop too. No complaints so far.
