Travel tech

Travel tech is about carrying less and having it work everywhere. A good kit charges every device from one or two plugs, fits in a small pouch and passes airport security without surprises.

These guides cover what belongs in a one-bag tech kit, how plug adapters differ from voltage converters, what to look for in a portable monitor and how noise-cancelling earbuds behave on a long flight. For batteries and airline limits, see the power section.
