After our fans repeated calls and long-awaited, in 2022, RovyVon finally brings the USB C charging port to the aurora series. Powered by a 330 mAh Li-Po battery, the upgraded A7 can be fully charged in one hour through the USB C charging port, it also supports USB C to USB C charging.  

Another new feature is that the 4th generation A7 comes with a metal switch, a magnetic pocket clip, and a tail base. So you can attach it to the Iron surface as a pending light while you are busy with other works. Oh, yes, it still keeps the GITD feature---glowing (sky blue) in the dark, making it visible in dark places.
