The LiitoKala Lii-L4 is a 4-channel charger suitable for all popular sizes of Li-Ion (lithium-ion) batteries.
Charges at a fixed current of 500 mAh, which is normal and recommended for almost all sizes of Li-ion batteries.
The charging channels are independent, so the Lii-L4 can charge 1, 2, 3 or 4 batteries simultaneously.
Charging indication is implemented using two-color indicators for each channel separately: the LED lights up red during charging and green when finished.
LiitoKala Lii-L4 is powered by a standard 5V USB port, it is recommended to use high-quality network adapters with an output current of at least 2 A. The set includes a charging cable (USB-microUSB).
As a power source you can use, for example, a smartphone power adapter, a car cigarette lighter adapter, a solar panel with a USB output or a PowerBank device (mobile power source).
Despite the apparent simplicity of this charger, it uses an optimal charging algorithm and is equipped with all the necessary protections against short circuit, overcurrent and incorrect battery insertion (polarity error).
Movable spring-loaded negative contacts adapt to the length of the batteries for a secure connection.
To ensure safety, the charger body is made of non-flammable plastic.
