The long story:

It all begins when I fall in love with USB powered LED bulbs/lights/lamps, early 2015, I saw how cheap LED lights had became when I was browsing Amazon and eBay, some are selling less than $1. So I bought a bunch of different USB bulbs, lamps and night-lights, I choose USB powered ones because I have a few of USB wall chargers (from old Android/iOS phones) collecting dust at home, I also have several USB external batteries.

It was all good until I found few minor problems, most of USB LED bulbs/lights/lamps do not have built-in switch, it is not convenient to plug in and pull out all the time. Some USB battery packs do not have switch, some are not able to turn off, the built-in switch are also easy to break.

I’ve waited for couples of months one to come to the market, finally I decided to design one myself.
