The Angel Eyes E4 is powered by the RovyVon hybrid battery system: the USB-C charges the built-in Lipo battery for daily use and high performance, while the replaceable AAA battery is for long runtime like camping, hiking, or whenever there’s no access to charging. The E4 body is made of lightweight and durable titanium.
The E4 has a dual summary, one has the default function and the other one is dedicated to quick access to Strobe and Momentary on. Blue charging indicator means in charge and the solid green means fully charged.
