A high-quality charger can identify lithium batteries and Ni-MH batteries, and then determine the charging mode. There is an integrated circuit on the protection circuit board of the lithium battery to store the characteristic data of the lithium battery. On the one hand, it allows the charger to identify the lithium battery to determine the "constant current" and "constant voltage" charging mode; on the other hand, it also allows the mobile phone to identify the lithium battery to determine the discharge method.

The charging method of Ni-MH battery adopts "constant current". The NiMH battery itself does not worry about overcharging. When Ni-MH batteries are overcharged, a reverse reaction occurs to prevent excessive voltage rise. This reaction will cause the battery to slightly heat up. In addition, Ni-MH batteries are usually equipped with a thermistor to prevent the battery from overcharging. The operating voltage of most mobile phones is about 3.6V, so three NiMH batteries are required. Generally, Ni-MH batteries will stop after overcharging to about 1.4~1.5V, and the maximum voltage of a three-cell battery is about 4.4V.

The charger is dangerous due to overcharging of lithium batteries, so its charging and discharging conditions are more demanding than nickel-cadmium batteries and nickel-hydrogen batteries. Some chargers on the market cut corners and identify mobile phone batteries as nickel-metal hydride batteries, and charging in "constant current" mode usually leads to overcharge of lithium batteries. A high-quality protection circuit board will protect the lithium battery to prevent the charger from continuing to charge. If you encounter the problem of poor circuit board design, it will not only protect the battery and cause the battery to be overcharged, but also cause the battery cell to deform, leak and explode due to overcharge.

The USB charger can intelligently display the real-time current and charging status of each charging port, including wireless charging on the screen. If you charge multiple devices at the same time, their charging status will be displayed in sequence.

Qi 10W wireless charging intelligently detects your device and automatically adjusts the power between 10W / 7.5W / 5W. USB fast charging 3.0 USB port is 4 times faster than standard charger. QC 3.0 port output: 5V / 3A, 9V / 2A, 12V / 1.5A. The output of the conventional USB port: 5V / 2.4A.

The ventilation holes on the back help the charging station cool down quickly. There is no need to disassemble the rubber/plastic/TPU case when charging the charger, and the electric wave can directly transmit the charging power through the protective case. Make sure that the thickness of your box does not exceed 5mm. Note: Magnetic, metal or other foreign objects can interfere with wireless charging.
