Ujjdwiurgh Full Protocol 22.5W Quick Charging Mobile Power Module QC4.0 Type-C USB Mobile Power Bank Circuit Diy Motherboard B

2. Small size, high power, low power ripple, sufficient materials, full protocol, good compatibility, stable performance 4. High efficiency, complete protocols, mainstream open protocols are basically supported. Most of the models support fast charging, in addition to cell phones if you support the 9V/2A protocol can also be fast charging 1.module for 3.2V lithium iron phosphate batteries, need to that the battery is not aging, the battery can be used in parallel not in series! 3. The product supports small current mode, digital tube display and LED power indication, more convenient to use. 5. Module volume is relatively small, the heat dissipation area is limited, high-power output heat is a normal phenomenon, we use high-quality materials, do not have to worry about the impact of heat !
