In the second post of my series “How to survive a day in Japan” I want to cover the topic Battery. It seamlessly follows the post how to stay connected to the Internet.
When being on the road all day, using your smartphone for navigation, reading, gaming and photography it is just a matter of time until you will run out of battery. During our preparation we read about powerbanks. You can find a various in all common stores such as Media Markt. They are cheap but not always of sufficient battery size or the quality we were looking for.
After reading some test-reports we decided to order 2 powerbanks:
Both come with a small bag which was ideal for putting the phone to charge next to the powerbank. Of course a cable is inclusive as well.
We wanted to use the smaller one for our daily tours and the bigger one for charging our devices in the evening in case we’d lack a power supply.
Since we were playing PokémonGo a lot we were quite happy to have a powerbank with us. And when we experienced that our Pocket-WiFi had a weak battery we were even more happy to have an additional battery pack with us.
During our stay in Japan we managed it quite well to have always one of the 2 powerbanks fully charged with us. Only during the first day we had some issues due to a wrong socket adapter. We bought one of Type B at Media Markt for Japan and experienced it to be completely useless (one of the topics we didn’t prepare well). It has the 3rd round connector which we noticed is rarely used in Japan. Our investment in two of these adapters turned out to be wasted. We bought a new one in a Japanese electronics market. It is Type C to Type A.
We didn’t use a special DC converter. In Japan you will have 100V instead of 230V in Germany for example. You should make sure that your devices are still running with this lower voltage and with the given frequency (50-60 Hz). We hadn’t any issue with our devices used in Japan (2 smartphones, 1 MacBook, the Pocket Wi-Fi, and sometimes one of the powerbanks as well).
For our next time we definitively will buy an additional socket adapter, because sometimes we had not enough space to charge all of our devices.
