SUSTAINABILITY

Everyday I use this system for charging Li-ion batteries which provide energy to my .ipod touch and smart phone.

However, for three year using, I have found something broken.

The serious case is a charge controller.. The reason , I believe, is that the machine itself is a cheap one. I assume that there are emerging so many same models by different makers in Chinese markets, if the products are found profitable. Some is good but....

I chose a following Taiwan made one. This is designed by a Japanese firm Denryo..
For 2 years, no problem so far.

The following photos show disconnection of a red wire on the back of a panel and a wire of a cigar socket..

The broken parts are fragile and are easily bent then it happens.
However, the both are not serious damages and can be mended.

For us, it is better to know where vulnerable parts are in the system.
