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), weldingconnection mode.The maximum charging current of the battery is 2.4a. Apple,Samsung and other high current charging identification lC, give full play to the 2.4acurrent advantage (mobile phone to carry out 2.1a/2.4 high current charging isrelated 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 enough power), battery reverse connection motherboard must burn. Be careful.
Battery and motherboard cable should not be too thin, as thick as possible. It can pass 5A current. It can't be too long. The interface needs to be welded.
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 IC. 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.

Multiple lithium batteries connected to the main board of mobile power supply need to be connected in parallel (not in series), the theoretical upper limit of the number of parallel connection.

Different specifications of lithium batteries should not be put together to avoid large battery loss, safety and other issues.
*In order to better protect the battery and prolong the service life of the battery, the simple method is to charge the batteries in parallel with the same voltage and then solder the wires.
*After parallel connection, the battery positive (B +) port of the battery positive connection plate and the battery negative pole (B -) port of the negative electrode connecting plate must not be connected in reverse, otherwise the board will be burned.
*Generally, it is not easy to tin the lithium battery. Generally, it is spot welding. If you use a soldering iron, the temperature of the soldering iron must be high.
