A travel-specific tool is usually a compromise, and three things make an ordinary one travel well: dual voltage, a travel lock and a case.
Rather than a second machine, check whether the one you own already travels.
Dual voltage. 100–240 V printed on the body means a plug adapter is enough.
A travel lock, or a long-press equivalent in the manual, stops the tool running itself flat in a bag.
A case with published internal dimensions. The ProCase for the OneBlade states 20 × 12.5 × 5.5 cm — about 7.9 × 4.9 × 2.2 inches — and names the ten models it fits.
Where a genuinely small tool helps is the nose and ear family — but check which half you are buying. Five of the twelve here run on a single AA or AAA and need no charger at all; five are USB rechargeable and need one; and the ROYAL at $16 is turned by hand, which is the only tool on the site that cannot run flat.
And the battery inside the tool may travel in either bag — it is a spare cell or a power bank that has to stay in the cabin, which this page sets out.
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.
