Nitecore has released a second in their "Concept" series. This is the Concept 2. A four cell, four emitter with on-board charging and an indicating switch. It looks pretty spectacular on paper, especially when it's noted that this tiny light is Nitecore's highest output light to date! Let's see how it breaks down.
A new 4-bay charger by Nitecore! My main and most-used charger is a Nitecore (d4), which I'm very satisfied with. I was hoping this would be a replacement/upgrade to my old d4; let's see how it fares!
