Nitecore UMS2 Intelligent USB Dual-Slot Superb Charger
Maximum Power and Performance
The Nitecore UMS2 Charger is a smart battery charger that will quickly and easily bring your batteries back up to performance standard. With a maximum output of 4,000mA, the UMS2 will efficiently charge your batteries in a quick manner, with a single slot being able to charge batteries back up to 80 percent in 55 minutes. Plus, with its intuitive charging capabilities and equipped LCD display, the UMS2 will alert you to any and all aspects of your battery. The Internal Resistance and Battery Health Detection will alert you to the internal resistance of that battery as well as its current condition. This feature will allow you to determine how useful these batteries will be and will enable you to make precise decisions about the longevity and lifespan of your rechargeable batteries.
Intuitive Design
The Nitecore UMS2 Charger features an intuitive and simple design that will prevent any harm from succumbing to your batteries. The UMS2 features an energy saving function that if there is no activity with the buttons or batteries within 10 minutes, the LCD screen will dim to save energy. Not to mention, that the design of the USM2 utilizes intelligent temperature regulation that will prevent the charger from overheating and ensure stable charging. The fin designs on the Nitecore UMS2 Charger will provide an enhanced cooling performance to disspate heat at a fast rate and avoid possible hazards, so you will never have to worry about your batteries or the state of your UMS2.

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.
