With a total maximum output of 4,000 mA and a single slot maximum output of 3,000 mA, NITECORE is introducing its brand-new UMS2, an intelligent USB dual-slot charger with QC input available that can charge two batteries at once and regulate each slot separately. A 3,500mAh battery may be charged to 80% capacity in just 55 minutes. Real-time battery health information, including "Good" or "Poor," internal resistance, charging current, voltage, charged volume, and charging time, may be seen on the LCD screen. It has the ability to automatically detect the battery's power level, choose the best voltage and charging method, and choose between three charging modes (CC, CV, and -dV/dt). Various charging needs can be satisfied by manually adjusting the charging parameters. To provide an infinite supply of power, the specially designed Micro USB port is compatible with a variety of transportable power sources, solar panels, and USB adaptors. In order to prolong the life of the batteries, UMS2 has an enhanced IMR battery charging algorithm that can monitor the entire charging procedure and make sure the cut-off voltage is always kept within safe bounds. 3.2V LiFePO4 batteries, 1.2V Ni-MH/Ni-Cd rechargeable batteries, 3.6V/3.7V Li-ion rechargeable batteries, and 3.8V Li-ion rechargeable batteries are all compatible with the UMS2. Several safety measures guarantee a safe charging process: automatic detection of internal resistance in batteries, protection against reverse polarity and short circuiting, protection against overtime charging, activation of Li-ion batteries after they have been overdischarged, and restoration of IMR batteries after they have been overdischarged. In addition to being made of sturdy, fire-resistant PC materials, the integrated temperature control system guards against overheating and maintains the stability of the charging process. NITECORE UMS2 Charger and NITECORE Keychain Tag are included in the package.
