Nitecore Um 4 USB Charger
A New Level of Smart Charging
The Nitecore UM4 Charger is a four-slot smart charger that will quickly charge batteries of varying chemistries and sizes efficiently. With a single slot max output of 1,500mA, it is possible to charge up to 80% of a 3,500mAh battery in 2 hours - you will always have batteries to use that are charged without losing any power to overheating or overcharging. Not to mention, with the four-slots, this charger is able to charge all four batteries independently from each other and you can control the batteries charging modes on the built-in LCD screen. The Nitcore UM4 Charger has a specially optimized charging program for IMR batteries. The program ensures the cut-off voltage is within safe limits and, unlike chargers without these capabilities, the UM4 will extend the lifespan of the batteries.
Other Unique Features
The Nitecore UM4 Charger has several features that are unique to Nitecore and its charging systems. This includes the inclusion of Over-Discharged IMR Battery Restoration and Over-Discharged Li-ion Battery Activations - these features ensure that your batteries will have an extended lifespan and will be in perfect working condition. There is also an Energy Saving Function within the UM4 which makes it go dim and save energy if there is no action to the buttons or batteries in 3 minutes. Plus, the LCD screen displays real-time charging information in order to help you inform and make your own decisions about your batteries quickly and easily. A perfect charger to add to your repertoire if you're looking for a smart charger that will provide you with anything you could ever need and more.
