I would recommend u a Kemei clippers they are copy of a wahl but they work very well. They gonna do job for u and they are cheap. If u not planing to Invest a lot of money. I think clipper is better option for u if u are gonna do the hair too. Just my advice and opinion but they are not charegeable with USB just to mention. Here it is on amazon : https://www.amazon.com/Professional-Clippers-Trimmer-Cordless-Stylists/dp/B083LLY3GS Cuz small trimmers have no lot of power and they gonna last u less than clippers. But if u prefer solid trimmers with small size i recommend Braun 3020. They cut good and they are small in size and they got s setup for changig size from 0-10 mm its good for fading your own beard but only problem is charging they charge 8 hours for one hour of working.
