Charger Nitecore UM4 Review

The NiteCore UM4 is a state of the art charger with a high performance board that supports Quick Charge 2.0. Recharging the battery is fast enough, which saves time. The current supply for each slot is separate. This guarantees an increase in the level of charging of batteries of different volume and size. The device automatically selects the system on which it will work, recognizes the current entering the device when the battery is connected, and then determines the desired operating mode: Fast - the highest initial current is 1500mA when synchronously charging 2 batteries at once. For four, each slot receives 750mA. Standard mode - one charging channel has 1500mA, 2 - 1000mA. Synchronous charging of all elements - 500mA. Connecting to external adapters The NiteCore UM4 charger is portable because it is equipped with a microUSB input that allows you to connect various USB power sources: solar panels, Power Bank, USB car chargers. Compatibility The charger works with many rechargeable batteries. Thanks to the modern assembly, regardless of the size, each element receives the required current indicator. Works with: Ni-MH / Ni-Cd 1.2V; Li-ion models 3.6V, 3.7V and 3.8V, 3.2V. LCD display The manufacturer has created a universal device with a display that makes it more functional and convenient to use. A good screen resolution allows you to get all the necessary information about the charge in real time, track the recharging period and the state of the device. Advantages of the model The four-channel NiteCore UM4 has a number of advantages: Quick Charge 2.0 modification fast charging systems. Synchronous current supply to 4 batteries. Independent control of each slot. The highest current value of one channel is up to 1500mA. Automatic charging detection and operating mode selection. Overcharge, overvoltage protection. Cooling fins dissipate heat to keep the device at an optimal temperature. Power supply from an external USB port Supply voltage (V) - 5.0, 9.0 Output voltage (V) - 1.48, 3.7, 4.2, 4.35 Charge current (mA) - 1000, 1500, 500, 750 Type of rechargeable batteries - IMR, Li-Ion, LiFePO4, Ni-Cd, Ni-Mh Battery size 10440, 14500, 14650, 16340, 16500, 16650, 17350, 17500, 17650, 17670, 17700, 18350, 18490, 18500, 18 650, 18700, 20700, 21700, 22500, 22650, 25500, 26500, 26650, 26700, AA, AAA, AAAA, C (R14), D (R20) Number of charge channels - 4 Number of independent charge channels - 4 Charging mode -dV / dt, constant charging voltage (CV), constant charging current (CC) Charging control type - automatic Charge indication - LCD display Protection against polarity reversal and overvoltage Protection against installation of batteries Temperature control Shutdown timer
