For cutting hair at home, yes — a flat battery halfway through a haircut is the one failure mode that cannot be worked around, and most clippers here run corded.
A shave interrupted by a flat battery is an inconvenience. A haircut interrupted halfway is a problem.
Published on this site: the Remington HC5811 states mains and battery operation with lithium power; both Philips clippers state corded or cordless use; the Remington MB5000 beard trimmer states corded or battery with continuous corded operation.
Where a tool is cordless only — the body groomers, which are designed for the shower — the runtime figure carries more weight.
The second benefit is longevity: a tool used plugged in for long sessions spares the cell, which on most household machines is not replaceable.
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.
