Merging two tools in one: smartphone battery and UV lamp

This is firstly a conventional external battery, light and elegant, iPhone or other smartphone, equipped with a USB plug. The charge level of the battery is indicated by blue diodes placed on the side. Space-saving, compact and resistant, the battery fits easily into a handbag or pocket.

The RAVPower Luster also has a second function as a UV lamp. This comes on by sustained pressure on the switch. The blue light will detect in the dark (as in an episode of "Experts") any physiological traces invisible to the naked eye. The lamp can in the same way be used to identify counterfeit. With a form particularly suited to its use, the lamp fits perfectly in your hand.
