EXCELLENT REVIEW!
I had totally missed this one. Really impressive what Nitecore did here. I like the premise of an external USB docked powersource and it’s smart that Nitecore didn’t try to go all proprietary with this. Obviously something like that Xiaomi power bank can deliver so much more than the Nitecore power bank, but then, doesn’t have the convenient and highly water resistant form factor of the Nitecore.
If I was a caver, I would definitely get this headlamp. Especially since deals are now coming up, lopping off $25 or more from the previously discounted price.
