4* 21700 Battery Holder USB DIY Power Bank Box 22.5W Fast Charging Housing Battery Case Quick Charge Solderless Mobile Power bank Kit (battery not included)
4* 21700 Battery Holder USB DIY Power Bank Box 22.5W Fast Charging Housing Battery Case Quick Charge Solderless Mobile Power bank Kit (battery not included)
● Output power: 22.5W (peak 27W)
● USB output: 5V/4.5A (VOOC), 9V/2.5A, 12V/1.87A (only 5V for multiple ports at the same time);
● IN input (Lightning): 5V/2A;
● Type-C output: 5V/3.1A, 9V/2.22A, 12V/1.67A (output is available only when PD protocol is supported);
● Type-C input: 5V/3A, 9V/2A, 12V/1.5A (does not support simultaneous input);
● Other functions: long press to turn on the LED light; reverse installation will not burn the motherboard.
● Color: Black, Orange
● Effective voltage: 3.3V-4.15V (spring has voltage drop)
● Supported Capacity: Up to 20000mAh (batteries not included)
Capacity requirement: The minimum actual capacity of the battery pack cannot be less than 10,000 mAh; otherwise, the battery will not be able to discharge power even if the power is not fully consumed.
Note: If the private protocol of the mobile phone is not supported (USB does not support fast charging), you can use PD charging (TYPE-C output). The PD public protocol output is more stable.
Fast charging specifications (supported protocols):
● (With data transmission charging cable, communication handshake is successful with one of the following protocols.)
● Support 5V, 9V, and 12V voltage input/output;
● Compatible with BC1.2, Apple, Samsung mobile phone fast charging
● Integrated Huawei SCP25W super fast charging output protocol;
● Integrated OPPO VOOC22.5W flash charging output protocol;
● Integrated QC2.0/QC3.0 Qualcomm output fast charging protocol;
● Integrated FCP Huawei, AFC Samsung input/output fast charging protocol;
● Integrated USB C DRP protocol, supports input/output fast charging;
● Integrated USB Power Delivery (PD2.0/3.0) protocol
● Support PD2.0/3.0 input/output
Charging specifications:
● Supports 18W charging, the battery end current is automatically adjusted, and the charging current can reach 5A.
● (For the first charge, it is recommended to charge to 100% and then charge for a few more hours to allow the battery to be thoroughly balanced.)
Discharge specifications:
● Output current capability: 5V/3.1A; 9V/2.22A; 12V/1.67A
● Support line compensation, synchronous switch discharge (5V/2A) efficiency can reach more than 95%
Multiple protections, high reliability:
● Built-in input overvoltage and undervoltage protection; integrated output overcurrent, overvoltage, and short circuit protection; built-in battery overcharge, over-discharge, and overcurrent protection; built-in IC overtemperature protection;
Note:
● The product is only allowed to install 21700 (21*70MM) or 20650 (20*65MM) batteries with a voltage between 3.5V and 4.2V. Batteries that are more than two years old and have more than 300 cycles are not durable.
● It is found that the charging is intermittent and can only be used for a few minutes or more than ten minutes.
● The mobile phone cannot be charged half of the time.
● These are all reasons for poor battery performance. In addition, the product does not support modification or welding.
● If a battery that does not meet the requirements is used, we are not responsible for after-sales service.
● The motherboard is equipped with an anti-reverse installation chip, and the motherboard will not be burned if it is installed in reverse. However, since the spring shrapnel is integrated, the battery is broken and short-circuited, one positive and one negative, and the series connection will cause the spring to burn.
● However, after reinstalling correctly, the motherboard can always be used normally and will not burn.
