Type C Input: 5V 3A / 9V 2A / 12V 1.5A
Output Parameters:
Micro USB Output: 4.5V 5A / 5V 3A / 9V 2A / 12V 1.5A
Type C Output: 5V 3A / 9V 2.2A / 12V 1.6A
Mainboard Interfaces: 1 Type C fast charging port (supports both charging and output) + 2 USB fast charging output ports
Battery Compatibility: Accommodates 2 x 1260110 battery cells (soldering required; batteries not included)
Internal Installation Dimensions: Approx. 110x60x23mm
Mainboard Features: Comprehensive protection including overcharge/over-discharge/overvoltage/overheat safeguards. High conversion efficiency with stable current and voltage output.
Note: 22.5W is the super-fast charging protocol ,VOOC Flash Charge, Bidirectional fast charging uses the PD 20W protocol. Simultaneous output from multiple ports 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. Connecting via twisted wires, alligator clips, or spring-loaded connectors may cause insufficient power supply, affecting charging/discharging. Ensure proper insulation protection for battery terminals to prevent accidental contact with the mainboard during assembly, which could cause damage.
3. Connect the battery positive terminal to the mainboard's B+ pin and the negative terminal to the B- pin. Do not reverse polarity, as this will burn the motherboard and ICs, leaving visible traces. This only occurs with reverse polarity or accidental contact.
4. Use 3.7V 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 motherboard. Burned boards are not covered under warranty.
5. The motherboard includes built-in protection. Soldered batteries require no additional protection board. Battery protection boards limit current; exceeding this limit will cut off output.
6. After installing the mainboard and batteries, secure the batteries with adhesive tape. For battery models with thickness discrepancies relative to the casing, assess whether spacers are needed to prevent a sagging sensation when pressing the casing after assembly. Issues like battery rattling or casing deformation due to failure to check thickness differences or secure batteries with tape constitute improper assembly. We assume no responsibility for casing damage or battery failure resulting from disassembly.
7. The snap-fit casing is not designed for repeated disassembly. Always test all functions—motherboard output/input, fast charging, buttons, display, etc.—before closing the casing. Ideally, perform several charge/discharge cycles to confirm functionality before sealing. Issues arising from assembling and closing the casing without prior testing constitute improper assembly. We assume no responsibility for casing damage or battery failure resulting from disassembly required due to such issues.
Instructions:
1. Regarding activating fast charging for your phone: Fast charging protocols are categorized as public or proprietary. This motherboard incorporates an intelligent fast-charging chip compatible with mainstream public fast-charging protocols, supporting rapid charging for various smartphone s. Before ordering, please verify your phone's compatibility with public protocols to ensure fast charging functionality.
2. Regarding heat generation during charging: When the power bank operates, current flows through the motherboard and chips, resulting in energy conversion losses. These losses dissipate as heat. During fast charging, higher power consumption causes more noticeable heat—a normal physical phenomenon.
3. Battery level display may appear inaccurate immediately after connecting the battery. The battery meter features self-learning capacity recognition. It will display accurately after several charge/discharge cycles.
