The Fenix Lighting HP30R V2.0 Rechargeable Headlamp features a separate battery case, powered by two 21700 Li-ion batteries. The headlamp is rechargeable via the USB-C port in the battery case, and the battery can be used as a power bank to charge other devices. The dial switch allows users to switch between four white spotlight output levels, and three neutral white floodlight output levels. The spot- and floodlight can be switched on simultaneously to deliver a max output of 3,000 lm.
