Japanese power outlet

If packing for a vacation to Japan it's helpful to know if you'll be able to power your vital electronics when you arrive. However without knowing which power supply is used you could bring the wrong charger, therefore leaving you having to buy or borrow a suitable adaptor on arrival. Varying different combinations of frequencies and region codes can all cause confusion when planning on staying in another country especially if you've never visited before. This isn't as complex as it appears, with only a handful of different types of plug sockets being used throughout the world this article tells you exactly what you'll need in advance to power the iPhone 3GS in Japan. This guide has been specifically written to stop you worrying if you'll be able to charge the iPhone 3GS when abroad.When travelling to Japan this page has useful instructions showing you how to supply power to your iPhone 3GS using their Type B or A Japanese 100 volt 60Hz wall outlets, please be aware that Type B wall outlets will be typically used by a majority of Japanese. Most power supplies will vary depending on which country you're taking a trip to therefore please read the WikiConnections travel power sockets list for a full list showing countries. If your iPhone 3GS charges slowly or does not power up when visiting Japan from a different region please check that it is compatible with a 110 volt power supply. Devices which come from another country which use a higher voltage (for example 240 volts) can take longer to charge or won't power up, so check that the iPhone 3GS is dual voltage (you'll find these are normally indicated by 100-240 volts) else you may need to use an additional transformer to ensure proper use. If you plan on staying somewhere like Tokyo we also suggest referring to the Japan National Tourism Organization Web Site [1] for more indepth details prior to travelling to the area. These instructions assume you are running Apple iOS 6 or greater on the iPhone 3GS.

What is the best power charger for the iPhone 3GS in Japan?

If travelling to multiple countries the best travel charger for Japan to buy is a multiple USB port adapter which includes compatible plugs such as a 4 port USB travel charger [8]. Japanese use two different types of plug sockets (B and A) and bringing this will ensure that you are covered for type A.

As these types of chargers are supplied with interchangeable pins and handle 100 - 240 volts will mean that you can travel to over 100 countries in North America, Europe, Asia and Africa just by switching the included plugs. If your iPhone 3GS supports Fast Charge (please note that not all USB devices do) then you'll benefit from much quicker charging times with one of these power chargers, along with additional compatibility with more power hungry devices. Unlike other chargers this will also allow you to charge multiple devices at once without needing to pack seperate power adapters on your trip to Japan. Because you are only packing a single lightweight USB travel charger will also keep the overall size and weight down, making it ideal to store in hand baggage as well as being convenient for recharging your iPhone 3GS at the airport or on the plane. Due to their flexibility these types of adapters can be used when back at home not just abroad so when you're not travelling they can sit under your bedside table charging multiple phones, tablets and speakers without using up an additional power outlet.

We suggest buying this type of flexible travel adapter at an electronics retailer. The power adapter illustrated below is the iKits 4 Port USB Wall Charger [8] which has been tested successfully for recharging multiple USB devices in numerous different countries.
