That’s right, your eyes aren’t deceiving you, the Primus boasts a full 300 watt max output. Of course with all that power, you’re gonna need a ton of battery life to support this beast of a mod. (3) 18650 batteries (batteries sold separately) are required to power the Primus up and are easily accessed via the magnetic battery panel.
