Multiple interface design: Type C + USB + Micro USB, supports simultaneous charging of multiple devices 4. Built-in multi-protection mechanisms: comprehensive safety safeguards against overvoltage, overheating, and overcharging/discharging 5. High conversion efficiency circuit design minimizes power loss for stable and efficient charging Parameter: Product Name: 22.5W Fast Charging Module Fast Charge Chip: IP5356 Input Parameters: 5V2A/5V3A/9V2.2A/12V1.6A Output Parameters: 5V2A/5V3A/9V2.2A/12V1.6A/10V2.25A Interfaces: 1 Type-C port + 2 USB ports + 1 Micro USB port Protocols: PD, QC, Apple, FCP, SCP, VOOC, etc. Display: LED display Features: Comprehensive motherboard protection including overcharge/over-discharge/overvoltage/overheat safeguards. High conversion efficiency with stable current and voltage output. Note: 22.5W supports VOOC Flash Charge protocol. Bidirectional fast charging operates at PD 20W protocol. Simultaneous multi-port output does not support fast charging. Assembly Instructions: 1. Upon receiving the mainboard, first connect the charging cable for input testing. Observe the display status and confirm the screen illuminates before proceeding with soldering. 2. For normal operation, the battery wires must be soldered directly. Connections via wire twists, alligator clips, or spring clips may cause insufficient power supply, affecting charging/discharging. Ensure proper insulation protection for the battery terminals to prevent accidental contact with the mainboard during use, which could cause damage. 3. Connect the battery positive terminal to the B+ pin on the mainboard and the negative terminal to the B- pin. Do not reverse polarity. Reversal will burn the mainboard; burnt ICs will show visible traces. This damage occurs only from reverse connection or accidental contact. 4. Use 3.7V ternary lithium batteries only. Lithium iron phosphate batteries are not compatible. Connect batteries in parallel, not series. Series connection creates excessive voltage that will burn the mainboard. 5. The mainboard incorporates built-in protection. Soldered batteries require no additional protection board. Battery protection boards impose current limits; exceeding these limits will cause output disconnection. Usage Instructions: 1. Regarding activating fast charging for phones: Phone fast charging protocols are categorized as public or proprietary. This motherboard employs an intelligent fast-charging chip compatible with mainstream public fast-charging protocols, supporting rapid charging for various phone s. Before ordering, confirm your phone supports public protocols to ensure fast charging functionality. 2. Regarding motherboard heating during charging: When the power bank operates, current flows through the motherboard and chip, causing energy conversion losses. These losses dissipate as heat. During fast charging, higher power output results in more noticeable heating—this is a normal physical phenomenon. 3. Battery level display may be inaccurate immediately after connecting the battery. The battery meter supports self-learning of battery capacity and will display accurately after several charge/discharge cycles. Package include: Module x1 Cable x2 label:yes
