NITECORE UM4 UM2 C4 VC4 LCD Smart Battery Charger for Li-ion/IMR/INR/ICR/LiFePO4 18650 14500 26650 AA 3.7 1.2V 1.5V Batteries D4

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.

  UM4 is a QC input available intelligent USB four-slot charger with a total max output of 3,000 mA and a single slot max output ofo 1,500 mA. With LCD dispaly for real-time charging infomation, it is equipped with a USB charging port for outdoor
  Nitecore UM4 is a universal smart charger compatible with almost all cylindrical rechargeable batteries, thus eliminating the need to own several chargers. The UM4 automatically detects Li-ion, Ni-MH and Ni-Cd batteries, and through manual selection is also capable of charging LiFePO4 batteries. Intelligent charging circuitry selects the optimal charging mode (CC, CV and dV/dt) for a given battery and each of the UM2's four microcomputer-controlled charging slots then monitors and charges the battery independently. Furthermore, an integrated digital LCD screen clearly displays charging progress, voltage, current while an intelligent automatic power-off function terminates current when charging is complete. The Nitecore UM4: The world's most advanced fully-automatic digital charger. It's as simple as insert, detect and charge.
