Specification:

• Brand new

• Type: 2S 8.4V 1A / 2S 8.4V 2A / 2S 8.4V 4A / 3S 12.6V 1A / 3S 12.6V 2A / 3S 12.6V 4A / 4S 16.8V 1A / 4S 16.8V 2A / 4S 16.8V 4A (optional)

• Working ambient temperature: -40℃ to +85℃

• Size: approx. 39*18*6.3mm

• Switching frequency up to 1MHz half-CV mode to compensate for voltage loss on battery internal resistance and trace resistor, automatic charge protection lower than input and short battery for battery voltage adapt well to input supply battery surge protection with limited driving capability.

• Apps: PDA, MP3 players, MP4 players digital cameras Bluetooth applications game player laptop li-on lithium battery 18650 mobile phone solar charger audio equipment portable devices POS, electric Fan TYPE-C charging equipment

• The input current is determined by the value of the two RCs, the charging voltage is determined by the chip and cannot be changed by the resistor.

• Fine workmanship and good performance.

• Easy to use.

• Long service life.
