One year has passed since the release in March 2016, and at the end of September it becomes the second generation model "Apple Watch Series 2"In collaboration model with Nike in October"Apple Watch Nike +"Also appeared Apple Watch.

The package of Power Bank for Apple Watch looks something like this.


I tried to take out the main body from inside. A pedestal for charging Apple Watch is embedded, and a film is affixed to this.


It is about this size when placed on the palm of your hand. It is extremely compact and looks just like the keys of a car, and the size feel is similar.


It is also characterized by metal fittings attached and hanging from key chain.


On the back is "Oittm" logo. The battery capacity of Power Bank for Apple Watch is 700 mAh.


The bottom of the main unit of the Power Bank for Apple Watch has a Micro - USB terminal for charging.


When charging the main body by inserting Micro-USB, the blue LED lamp blinks like this.


Power button on the side.


Nothing is on the other side.


That's why I tried charging the 42 mm model of the original Apple Watch completely discharged using a fully charged Power Bank for Apple Watch.


Because it is disturbing if you keep on a band ......


When charging it seems better to remove the band and place it on the Power Bank for Apple Watch.


To charge Apple Watch with Power Bank for Apple Watch, press and hold the power button on the side of the main unit for about 3 seconds.


Apple Watch turned on in about 5 minutes from the start of charging.


In 30 minutes from the charge start, the battery of Apple Watch was able to charge up to 27%.


After 40 minutes, the number of blue LED lamps of Power Bank for Apple Watch turned from four lights to three lights turned on.


After 45 minutes, Apple Watch's battery is fully charged up to 41%.


I was able to charge up to 58% over 1 hour, but the blue Blue LED lamp of Power Bank for Apple Watch decreased to 2 lights around here.


At 1 hour 30 minutes later, the battery of Apple Watch was able to charge up to 89%.


With 1 hour 45 minutes passed, the battery is 94%.


Up to two hours from the start of charging, I had a battery of Power Bank for Apple Watch, but the blue lamp ceased to light up when I passed 2 hours and 3 minutes, the battery became empty. At this point Apple Watch was able to charge from 0% to 97% of the battery.


The battery capacity of Power Bank for Apple Watch is 700 mAh, the battery capacity of Apple Watch is 205 mAh of the first 38 mm, 273 mAh of 38 mm of the second generation, 246 mAh of the first 42 mm, and 334 mAh of 42 mm of the second generation. I was able to charge the 42 mm model of the original Apple Watch from 0 to 97%, so it seems impossible to fully charge the Apple Watch Series 2 with Power Bank for Apple Watch. However, if you have a fully charged Power Bank for Apple Watch, it is obvious that the battery of Apple Watch can be charged as much as a whole day, so it might be perfect for carrying around if it is for you.

In addition, Power Bank for Apple Watch is sold for $ 49.99 (about 5300 yen) on Amazon.com, but in Japan's Amazon.co.jp it is not handled at the time of article creation.
