– USB input with automatic adoption for optimal charging.
– Multiple charging safety valves
– Lightweight and portable for outdoor activities
– Available for large batteries 20700, 21700 and others.
Maximum charging current of up to 800mA
When a battery with a voltage below 2.9V is charged, the U1 will automatically activate the
Low Current chargingfunctionthat charges the battery with a current of 100mA.
If a battery with a voltage higher than 2.9V is charged for charging, the U1 will automatically activate the
chargingfunctionwith the Maximum Current 800mA.
Compatible with 3.6V / 3.7V rechargeable batteries
Available for large batteries such as 20700, 21700.
Smart charge selection function (CC and CV)
Automatic adoption of the optimal charging function
Micro-USB input for outdoor charging.
Compatible with a wide variety of energy sources such as solar panels, USB adapters, power banks etc.
Clear and Simple Power Indicators
For real-time monitoring of battery power level and charge status.
Ability to activate excessively discharged Lithium Ion batteries.
The U1 is capable of activating overcharged Lithium-ion batteries with a protection circuit.
After inserting the battery, U1 will check and activate the battery before charging begins.
Multiple Insurance Lockers during Charging.
– Short Circuit and Reverse Polarity Protection
If a battery with inverted polarity or short circuit is inserted,
all 3 indicator lights will start flashing to indicate the problem.
– Intelligent Thermal Protection.
If the charger overheats due to the high ambient temperature, U1 will adjust the charging current
to protect the charger and battery.
– Automatic termination of charging immediately upon completion.
When the battery is fully charged all three LEDs will light steadily and U1 will end the charging process.
