Not USB-C as the specifications note

I bought this product because the web site says it is USB-C. It is NOT! Even Nitecore's website pictures show a Micro USB jack, which is what mine arrived with. The charger works, but now I have to change my AC adapter and car cables. What's going on here? Are there two versions out there?

just being honest

I gave a good 3 months plus before I decided to review. Part 1 is, I received a defective unit. They sent me a replacement without asking for the defect, so my rating is much higher for this reason. Unless I'm doing something wrong this new one is heading towards the same issue as the first one. The past month the right side only shows 2 bars, says good, but does not charge even when I take the left side out. So basically this is now a single battery charger which is not ideal as my device needs 2 batteries to function. I have used other outlets, and 4 different battery brands and they all have identical issues. really a shame because the first month was flawless and you cannot beat the price. But maybe that is the issue. You get what you pay for. I am not saying do not shop Nitecore. But I am posting for other people researching chargers. maybe I am the only one at the moment........

Indispensable

Does a quick, efficient job and provides independent feedback on the battery status in each slot. I tested batteries charged while in a flashlight against batteries charged in this unit. The unit was faster yet did a more thorough job, charging the batteries more completely. But it also protects against overloading. With this unit, you can get the longest life out of your batteries. Great product. Now I’m going to get the four-slot.
