I will say NITECORE is one of those brands that believe in innovation which is why they are the leader in certain products. I've had multiple NITECORE chargers for over a decade and every single one is still going strong with zero malfunctions.. I highly advise/recommend that you verify you are receiving AUTHENTIC NITECORE products with utilization of the verification process on NITECORE's website.. There are plenty of counterfeit products, that don't come close to the authentic products. Quality, craftsmanship, durability, attention to detail, longevity, ease of use, and customer support of NITECORE is second to none. I advise all buyers add the car charger to these products.. Thank you for supporting America and it's Armed Forces!!
