Nitecore UMS4 Intelligent USB Four-Slot Superb Charger

Smart Charging At Its Best

The Nitecore UMS4 Charger is a four-slot smart charger with intuitive features and intelligent charging programs. The QC input of the UMS4 allows for a maximum output of 4,000mA which will quickly recharge your batteries with efficiency and with minimal discharge. If you're only using a single slot, thats no problem, the single slot maximum output of Nitecore UMS4 Charger is 3,000mA which will charge 80 percent of a 3,500mAh battery in 55 minutes, giving you plenty of time to charge up for your next use. Other smart features of this device is the Internal Resistance and Battery Health Detection which will alert you to the state of your battery. The UMS4 also provides real-time charging information, such as battery voltage, charging current and duration, so you can monitor the status of your battery.

Temperature Conscious

The Nitecore UMS4 Charger is designed to prevent overheating of both your batteries and the charger itself. With a built-in fin design at the edges of the charger, the UMS4 is able to bring a cooling performance that will disperse heat rapidly. Plus, the UMS4 has intelligent temperature regulation that prevents the charger from overheating and will ensure a stable charging process. These features, combined with the durable and fire retardant materials that make up the UMS4, will protect you and your batteries from danger. Not to mention that the energy saving function, which is when the charger dims after 3 minutes of inactivity, will ensure that the UMS4 is always ready to use and won't waste any charge of its own.
