Various voltages and standards can often be confusing when planning to travel to a different country especially for the first time traveller. These instructions were written to prevent you worrying if you'll be able to charge your iPhone 3GS when you are staying abroad.This page contains a useful guide telling you what you'll need to supply power to your iPhone 3GS when you are travelling to Japan by using the standard Type B or A 100 volt 60Hz power outlets, a majority of Japanese normally use the Type B wall outlets. If the iPhone 3GS slowly recharges or doesn't turn on when you are visiting Japan from a different region please check that it is compatible with a 110 volt power supply. Typically devices which originated from a country which use a higher voltage such as 220 volts either take longer to charge or won't turn on, check your device is dual voltage (you'll find these are normally marked with 100-240 volts) otherwise you may need to use an additional power converter to ensure proper use. These instructions assume that you have installed 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.
