Inside a Cooyuen USB rechargeable keychain light.

A more down to earth LED keychain light with integrated USB plug for charging, a generous 80mAh cell and bright output, but with limited functions.
This LED flashlight uses two standard 5mm LEDs which are pushed quite hard at 40mA each. The circuitry is fairly sensible and the only thing really missing is a lower intensity mode for high run time, and the ability to detect when it's been on for a few seconds and to turn off on the next button press instead of cycling through the three modes.
Despite being cheap, it actually comes in very good packaging and seems to be quite well thought out.
The light also has a high output UV LED on the side which is capable of making UV identifiers in banknotes glow.
