Description
Nitecore UM2 Intelligent USB Dual-Slot Charger
Quick and Intelligent Charging
The Nitecore UM2 Charger is an intelligent USB dual-slot charger that will change the way you charge batteries. The UM2 has a QC input that enables a total max output of 3000mA, so that you can realistically charge a single 3,500mAh battery up to 80 percent in 2 hours in one slot. You will be able to charge batteries quickly and put them back to use just as fast with the Nitecore UM2. This charger has the capability to charge two batteries simultaneously while controlling both of the slots independently, meaning that you will be able to see how much charge your batteries get without worrying about any discharge making your batteries last much longer. The Nitecore UM2 will automatically detect your battery's charge level and provide appropriate voltage and charging time to ensure the safety and longevity of battery life.
The Nitecore UM2 Charger is equipped an LCD display so you can watch your batteries charge in real-time and see the information in a quick glance. You will never worry about your batteries overheating, overcharging, or losing power because you will know as soon as the charger does. Moreover, this charger has a unique cooling fin design that dissipates heat rapidly to enable a cooling performance while simultaneously protecting you and your batteries from possible hazards. Plus, with the addition of intelligent temperature regulation, this charger will not overheat and ensure the stability of the charging process. These features make the Nitecore UM2 Charger a necessity in making sure your rechargeable batteries last and last.
