Micro/Type-C USB 5V 2.4A Dual USB 18650 Boost Battery Charger Board Mobile Power Bank Accessories

CHARACTERISTIC PARAMETERS

1. Input interface:

type-C and microusb.

2. Output interface: 2 high quality USB interfaces (high current loss, small loss)

maximum 2.4a.

3. Battery interface: support 3.7V lithium battery (fully charged with 4.2V), welding

connection mode. The maximum charging current of the battery is 2.4a. Apple, Samsung and other high current charging identification IC, give full play to the 2.4a current advantage (mobile phone to carry out 2. la/2.4 high current charging is related protocol)

4. High efficiency charge discharge design, up to 90%

5. Ultra small ultra-thin size, 55 *19* 8mm.

APPLICATION NOTES

Motherboard received, first connected to the charging head test, see the LED light on state.

Normal application, the battery must be welded, (wire twist connection will not supply enoughpower), battery reverse connection motherboard must burn. Be careful.

Batteries can only be connected in parallel, can not be connected in series

Make sure that the battery is good. If the battery is fully charged when it is connected and the mobile phone cannot be discharged, most of the batteries are aged and scrapped.

The battery should not be protected. Some batteries are not originally used for the power bank. They have a protection board, which will limit the current. If it exceeds one or two amperes, the output will be protected and disconnected.

if the board is connected in reverse, it will burn. There will be traces of burning 1C. Only the reverse connection will happen. So we won't bear the consequences of reverse connection

The type-C port is only input, not output

Input current refers to the input current of the battery.
