QC fast charge, total output current 4000mA
Single tank charging current up to 3000mA
Optimized charging program for IMR battery
UMS2 has an optimized charging program, which is fully optimized for the charging status of the IMR battery and closely monitored the whole process to ensure that the charging cut-off voltage of the IMR battery is within a safe range. The safety performance is greatly upgraded, and the battery life is greatly extended.
HD LCD display, real-time monitoring of charging status
Battery health monitoring
Real-time monitoring of charging status
Short press "V" key to switch to display charging status, charging information, etc.
Smart charging mode
UMS2 automatically selects the appropriate voltage and charging mode for charging (CC, CV, -dV/dt) according to the battery type and capacity.
Smart charging mode
For various charging needs, the charging mode can be set manually.
Long press the "C" key to enter the setting mode: charging voltage (3.7V/4.2V/4.3V) and charging current (100mA~3000mA) can be selected
Micro USB interface multi-source input
It is suitable for various outdoor power sources such as mobile power supplies, solar panels, and USB adapter input to ensure uninterrupted outdoor power consumption.
Lithium battery repair function
When an over-discharged IMR lithium battery is inserted, the display will show "EE EE". If you need to repair, long press the "V" key to enter the repair mode, after the repair is completed, it will automatically enter the normal charging mode.
Battery activation function
UMS2 has an activation function for over-discharge lithium batteries with battery protection circuits. When the battery is inserted, the battery will be detected and automatically activated. A battery that cannot be activated will be regarded as a damaged battery, and the display will show "EE EE" to prompt the user.
Anti-reverse and short circuit protection
When the battery is reversely connected or short-circuited, the display will show EE flashing alarm.
Energy-saving charging mode
The LCD high-definition display will automatically dim after 10 minutes of lighting to enter power-saving mode
Made of PC fire-retardant materials
No fear of complex and changeable outdoor charging environment
Fully automatic intelligent temperature control protection program
Built-in real-time temperature control protection system to prevent high temperature and ensure the stability of the charging process.
Unique cooling fin design
The heat dissipation design of UMS2 is distributed on the left and right sides of the device, which can better accelerate heat dissipation and avoid the possibility of heat accumulation.
