Most headlamps fit a pretty standard profile these days - a couple different brightness settings, some weather durability, and possibly a red-light function to preserve your night vision. Black Diamond's ReVolt has these standard features, but it’s also rechargeable via USB which is a huge advantage for most backcountry uses. This isn’t a review which pits multiple rechargeable headlamps against each other in order to nitpick the minor differences, rather it’s a quick rundown of why the ReVolt works for the majority of my needs and why you might consider getting a rechargeable headlamp in the future.
