A setting that prevents the tool switching on in a bag. Two products here publish one: the Panasonic ES-ALT4B shaver, and the MANSCAPED Pro trimmer, which engages it by a three-second press.
The problem it solves is a power button pressed against the inside of a case for four hours, and a tool that arrives flat.
Panasonic states it among the features of the Series 700 shaver. The MANSCAPED Pro at $40 publishes the mechanism as well as the feature — press and hold the lock button for three seconds — which is the only place on this site the sequence is written down.
It is worth knowing how rare that is. Two other trimmers on the same shelf carry a “Travel lock” line with “Not published” against it, which is a maker being asked the question and not answering it. Where no maker lists it, the manual often describes a button-hold sequence that does the same thing, and that is where to look before assuming the tool has none.
It is a small feature and it is the difference between a shaver that works on the first morning of a trip and one that does not.
Two related travel points from our pages: a tool with its cell installed may go in either bag — only a spare cell or a power bank stays in the cabin — and the voltage rating decides whether a plug adapter is enough.
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.
