Best overallKorjo USB A+C & Power Adaptor for Japan

This is the one we’d pack for most trips to Japan. It turns one wall socket into an Australian socket plus a USB-A and a USB-C port, so your phone, earbuds and a camera battery charger can all run off the same spot. That’s handy when there’s only one spare socket near the bed, and it means you can leave the separate USB charger at home.

It goes into both kinds of Japanese socket, and our Japan page in the Plug Finder has the sockets and the power at a glance.

The catch is that it takes two-pin Australian plugs only, so a laptop charger with a third pin for the earth won’t go in. Check every charger you’re packing before you leave.

With both USB ports in use, each one charges a bit more slowly, which is fine for a phone and a watch topping up overnight. If your laptop has a two-pin charger, it’s better off in the Australian socket. Next to the DAYEFORUN it has one fewer USB port and comes on its own rather than as a pair. Next to the plain Korjo it costs more, but it doubles as a USB charger, so you pack one thing instead of two.

Best for two travellersDAYEFORUN Japan Travel Adaptor (2-pack)

Travel as a couple or with a friend and you’ll know the routine: one socket by the bed, two phones that both need it. This box has two adaptors, so you each get your own, and each one has an Australian socket, two USB-A ports and a USB-C port. That’s four things charging from one wall socket, per person.

Like the Korjos, its Australian socket only takes two-pin plugs, so check your chargers for a third pin before you pack. The USB ports slow down when you charge several things at once. That’s fine for the overnight phone, watch and earbuds routine, so think of it as a bedside charger rather than a fast one.

For a solo trip we’d still pack the Korjo USB adaptor, because one small adaptor with a USB-C port is all most people need on their own. For two people, though, a pair in one box costs less than two of the Korjo, and nobody’s waiting their turn.

Best valueKorjo Adaptor – Japan

The plain Korjo does one job: your Australian plug goes in one side and two flat pins go into the wall. There are no USB ports, so you’ll plug your phone’s own charger into it, but it’s the cheapest of the three and small enough to fit in a jacket pocket.

Like the USB version, it takes two-pin plugs only. The black trim marks it as the Japan one, which helps if you’ve got a drawer of Korjo adaptors from other trips. If you already travel with one USB charger that handles your phone and watch, this is all you need to get it into the wall.
