Our products support advanced charging protocols, PD, PPS and wireless Qi2.
What is PPS?
As the major brands in the market have developed their own fast charging protocols, the quick charging protocols in the market are disorderly. Therefore, USB-IF released PPS to summarize and unify different charging protocols.
PPS is a protocol that will be adopted by major brands at present and in the future, such as Apple, Samsung, Huawei, etc. PPS is a power supply type supported in USB PD3.0, which is a kind of USB PD protocol output can achieve voltage and current regulation of the charging standard, PPS specification integrates the current high-voltage and low-current, low-voltage and high-current charging mode, so this charging standard has very good compatibility. In addition, PPS specification can adjust the output voltage according to the power of the equipment, so as to achieve higher efficiency and lower temperature.
The PPS (Programmable Power Supply) standard refers to the power supply can exchange data with the power supply every ten seconds, so that the power supply can dynamically adjust the output voltage and current according to the condition of the receiving product specifications. The voltage range is between 3~ 21V, with increment of 0.02V. Due to PPS, USB-IF Association has also added "PPS Voltage Step Test" and "PPS Current Limit Test" to ensure that the current and voltage dynamic adjustment of the device during the charging process are in compliance with the Association's specifications.
Our omni-directional safety certificates
When designing power bank modules, implementing short circuit protection is a critical safety measure.
Here's a detailed approach we use to ensure effective short circuit protection:
- Sense Resistor and Power MOSFET
- Microcontroller Unit (MCU)
- Fast-Acting Protection Circuit
- Battery Protection Re-activation
- Thermal Shutdown
- Overcurrent and Overvoltage Protection
- Mechanical Design to protect the power bank module and connectors
By integrating these measures into the design of power bank modules, we can significantly enhance the safety and reliability of the device. It's also essential to test the design thoroughly under various conditions to ensure all safety features are functioning correctly.
