It’s 2022 which means AAA batteries have become the norm. Numerous headlamps have complied with USB-rechargeable models, and this one from Petzl Actik Core is by the far our top pick. This headlamp is a complete package with 450 lumens of maximum brightness, a lengthy battery life, with consistent performance throughout its duration of burn (some headlamps dim out, however the Actik remains bright until the finish) and a weight of less than 3 ounces and an intuitive interface. The French-based Petzl is at the forefront of headlamp technology for a long time with their Actik Core is an example of this the right direction.
USB rechargeable models are not ideal for extended stays out in outdoors (unless you carry an external solar panel or power bank) However, the Actik Core is a great solution that comes in the form of the battery pack, which can be used to replace AAA batteries. The headlamp was an excellent choice that we have used before, but this flexibility puts it at the top of our list of. The Petzl is so durable that you may not require an old battery. A single charge gave us for the duration of a 6-day biking excursion within the San Juan Mountains (our BioLite 330 required numerous charges). The Actik’s water resistance isn’t groundbreaking (IPX4 protects against water and rain) and you’ll have to pay for the highest-end technology at $70, but they aren’t major sacrifices to get an efficient headlamp that can last for a long the years.
