Protection-free board design: integrated protection function on the main board, directly weld the battery to save space and simplify assembly5. Intelligent self-learning power: automatically calibrate the power display after the first use, accurately reflecting the remaining battery powerProduct Name: 22.5W fast charging moduleInput Parameters: 5V3A/9V2A/12V1.5AOutput Parameters: 5V3A/9V2A/12V1.5A/10V2.25AInterfaces: Configure 1 Type-C fast charging port (can be charged as well as output) + 2 USB fast charging output portsProtocol: PD, QC, APPLE, FCP, SCP, VOOCFunction: with over-charging / over-discharging / over-voltage / overheating and other kinds of protection, high conversion rate, current and voltage stabilityNote: 22.5W is the super fast charging protocol, bidirectional fast charging is the PD20W protocol, multiple interfaces at the same time the output of the fast charging of noBattery compatibility: Accommodates two 1260110 cells, requires soldering (batteries not included)Internal installation dimensions: Approx. 110x60x23mmAssembly instructions:1. Because the motherboard screen is fragile, upon receipt, please power on the screen to test whether the screen is normal after welding on the tin, the screen wires will be extruded by external forces will be spent on the screen burst screen, please pay attention to protect the screen when using.2. Normal use, the battery wires are welded up, wire twisting / alligator clips / spring box and other access methods will lead to insufficient power supply to affect the charging and discharging, the battery positive and negative need to do a good job of insulation protection to avoid damage caused by the use of the process of touching with the motherboard.3. motherboard B + position connected to the battery positive, B - position connected to the battery negative, do not connect the reverse, the reverse will burn the motherboard, burn board IC there will be traces, only the reverse or touch connection will occur.4. Access to the battery to use 3.7V ternary lithium batteries, lithium iron phosphate batteries can not be used, the battery parallel welding, not in series, series voltage is too high will burn the motherboard.5. The motherboard has a protection function, welding batteries do not need to add a protection board, the battery protection board has a limit on the current, beyond the limit will disconnect the output.Mobile Power Bank Kit Assembly Instructions:1. The mainboard screen is fragile. Upon receipt, power on to verify screen functionality before soldering. External pressure on the screen flex cable may cause screen distortion or failure. Handle with care to protect the screen during use.2. For normal operation, the battery wires must be soldered directly. Connecting via twisted wires, alligator clips, or spring-loaded terminals may cause insufficient power supply, affecting charging/discharging. Ensure proper insulation of battery terminals to prevent accidental contact with the mainboard during use, which could cause damage.3. Connect the battery positive terminal to the motherboard's B+ pin and the negative terminal to B-. Do not reverse polarity, as this will burn the motherboard. Burned ICs will show visible traces, which only occur from reverse connection 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.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.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 sunken feel when pressing the casing after assembly. Issues like battery rattling or casing collapse 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 under such circumstances.7. The snap-fit casing is not designed for repeated disassembly. Always thoroughly test all functions—including motherboard output/input, fast charging, buttons, and display—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 for use:1. On the activation of cell phone fast charging, cell phone fast charging public and private protocols to distinguish between the motherboard adopts intelligent fast charging chip, compatible with the mainstream public fast charging protocols on the market to meet the needs of different brands of cell phones for fast charging, before placing an order, please confirm that their cell phones are compatible with the public protocols, to avoid not being able to trigger the fast charging!2. On the charging of the motherboard heat problem, charging treasure in the work, the current through the motherboard and the chip, energy conversion will have loss, this part of the loss in the form of heat emitted, fast charging, the power is large, the heat is more obvious, this is a normal physical phenomenon.3. Just connected to the battery digital display power will be inaccurate, the power meter supports battery capacity self-learning function, charge and discharge cycle a few times after the normal.
