Discover a mobile battery for smartphones at the 100-yen shop Daiso! It's a 500 yen product, but it's an affordable price for a mobile battery. I was curious about this item, which is indispensable for travel and leisure, which is increasing during this period, so I tried it.

Daiso's mobile battery

The product name is "1 port mobile battery for smartphones". Available in two colors, white and black, both are simple and plain. This time I chose white.


The size is about 11.5 cm in length x 7 cm in width x 9.5 cm in thickness. It weighs 103g (3.63oz). Comes with a microUSB cable for charging. A separate USB outlet is required for charging.




The spec is 3,000mAh capacity and 5V-1A input / output. It can be fully charged in about 4 hours. The blue LED light on the side informs you of the degree of charging, which is convenient. It is full when four shine.


When connecting a smartphone, the attached cable is OK for microUSB, but in other cases such as iPhone, a USB cable to connect to the battery is required separately. You can use the one you normally use for charging.


When I charged it with iPhone6, I was able to charge the remaining 23% of the battery to 80% in about 1 hour and 99% in about 2 hours. It's slower than the power supply, but it's not noticeable. Without being disconnected on the way.




At this point, three LED lights were shining, so can I go again? I thought, but the power was cut off at 16% → 44%. It seems good to think that it can be fully charged once.

It's not as good as it sounds, but it's a thin, light, and affordable mobile battery. It looks good to decorate with stickers etc. ♪
