1-10 Uds 22,5 W banco de energía 5 puertos bidireccionales carga rápida módulo de energía móvil placa de circuito DIY Kit de placa base QC4 + PD3.0

Product parameters:

The charging process is divided into the following three processes: trickle mode, constant current mode, constant voltage mode. When the battery voltage is lower than 3V, the charging module is in trickle mode and the charging current is 300mA. When the battery voltage is greater than 3V, the charging module enters the constant current mode and charges at full speed according to the set target current, with the power of about 21W. When the battery voltage rises to the target charging voltage (such as 4.2V), the charging module enters the constant voltage mode, and the current gradually decreases while the terminal voltage of the battery remains unchanged. When the charging current decreases to the charging cutoff current, the charging ends. If the battery voltage drops to 0.1V lower than the target charge, the battery automatically starts charging again. (Note: If the voltage exceeds 4.2V, it is normal and will not damage the battery. If the voltage is 4.2V, the lamp still flashes, which means it is not full yet. Full charge is not just to see the charging voltage.)

The motherboard has a total of 5 USB ports, Are respectively the Type A1 + A2 + Type Micro - B + C + 20 Type, including the Type A1 and Type - A2 support QC3.0 / QC2.0 AFC/FCP/SCP/PE2.0 / PE1.1 / SFCP/VOOC quick charge output;

Type C support PPS/PD3.0 PD2.0 / QC4 + / QC3.0 / QC2.0 AFC/FCP/SCP/PE2.0 / PE1.1 SFCP quick charge output, support PD3.0 PD2.0 /

Note:

1: motherboard external battery line needs to be able to pass 10A current, at least with more than 1 square copper wire, ordinary line to use 1.5 square. It doesn't have to be too thick, but it shouldn't be too thin. Too thin could be a safety hazard. (because there is a lot of current at the battery end)

2: The motherboard comes with a protection chip, the battery can not be added to the protection board, if there is please remove the protection board, directly our motherboard connected to the battery. (Because the own can not be too much current, the output power is protected)

3: The use of crocodile clip motherboard test use of small partners please do not charge mobile phones, do not ask why, in short, can not be used in this way. Need to charge mobile phone must be welded must be welded (very many buyers are not obedient, a problem on my motherboard how bad, motherboard how can not fast charge, motherboard how can power restart, etc., trouble according to the requirements of the operation, don't be self-righteous.)

4:4.2V 18650/ polymer/ternary lithium battery can be used for the battery, large single unit can be used, multiple 18650 parallel can also be used, can not use iron lithium battery, disposable dry battery, nickel hydride, lead-acid battery, nickel cadmium battery, etc. Batteries cannot be connected in series. For the first time, there will be power display is not allowed to wait, please discharge the power and then full, the first charge can continue to charge for more than 5 hours when the four lights are fully on, will not charge the battery, there is no need to worry.

5: the motherboard must be preset battery capacity, so about how much battery capacity must be noted or with customer service, otherwise take the shell of the default 30000mAh, without the shell single motherboard default 20000mAh. Or later replace the resistance by itself.

6: Support OPPO flash charge, support Huawei Super Fast charge, different protocols have different power, know well before shooting. This plan has been around for a long time and supports everything except for some phones that don't support fast charging. (The mobile phone is not supported because the agreement of the mobile phone is not open, so the third party can not use it. If you want to use it, you can only go to the official website of the mobile phone to buy.)

7: This shop 22.5W motherboard are the same scheme, the agreement is the same, comprehensive, the basic shape is not the same, which to shoot which, the shell will have a map behind the details, no shell is only the motherboard in the shipment.

D3, D4, D5 and D6 are power LED. LED1 is the fast charge indicator.
