Скачать или смотреть First look at a cheap USB power bank from a "dollar store" in Tokyo

We take a look at a USB power bank sold at Daiso (a "100 yen store"; an equivalent to a "dollar store" in Japan) which is being sold for 300 yen (approximately 3 USD). These things are generally called "mobile batteries" in Japan.

It exhibits some strange behavior, such as power cutting out every few seconds, when using a load that it probably is not designed for. The page which contains details (in Japanese) that I mentioned in the video is here: http://d.hatena.ne.jp/wakwak_koba/201...

I've tried connecting a resistor that pulls 1A, along with a power LED connected through a boost converter to bring the voltage up to 12 V; the "mobile battery" behaved in different ways when each of those things were connected.
