Only if it states corded operation, and four tools here do — three of the four clippers and the Remington MB5000. On everything else, assume not: no listing on this site says it is permitted, and one says the opposite.
The distinction is between a tool that runs on wall power and one that merely charges from it.
Published on this site: the Remington HC5811 and the Philips HC5630 and HC7650 clippers all state corded or battery operation. The Remington MB5000 beard trimmer states the same.
Where a tool is cordless only, the manual is the authority and using it plugged in may not be possible at all — on many designs the circuit simply will not run the motor while charging.
The one listing on this site that says anything about unplugging says something narrower than people assume. The AVENHO air styler states “Always unplug after use; avoid using near water” — which is a rule about AFTER, not about during, and it is the whole of what the catalog publishes on the subject. Nobody here states that a tool must be unplugged to run.
For tools rated for wet use the constraint is obvious anyway: five of the eight shavers here state a waterproof or wet-and-dry rating, and none of the eight states corded operation at all.
Check your own manual before you follow anything here. Temperatures, water ratings and supply voltages differ from model to model, and the maker’s own figures take precedence over anything written on this site. A supply of the wrong voltage is a failure rather than a slow charge, and the figure is printed on the tool — not inferred from a connector that happens to fit.
