Description
Home Arduino Module Sensor Chips About Us Product Features: 1. Compact size: Dimensions only 16*12*4.4mm. 2. Operates at 4.5-5.5V, compatible with single-cell lithium batteries (parallel connections unrestricted), maximum 1.2A. Provides stable 1A current under specified conditions. 3. Compatible with various 3.7V lithium batteries, including 18650 and polymer cells. 4. Features overcharge and over-discharge protection. Over-discharge cutoff at 2.9V, charge cutoff at 4.2V! 5. Automatically switches to output mode when no external input voltage is present. Supports low-current output at 5V, delivering approximately 450mA. When outputting 1A, voltage fluctuates between 4.9V and 4.5V based on battery capacity. 6. Automatically switches input/output: Charges battery when external voltage is present; discharges otherwise. Charging: Green LED flashes; full charge: steady green. Discharging: No LED on idle; blue LED on under load. Standby power consumption: approx. 0.8mA. Product Specifications: Input/Output: 5V Current: 1A (max 1.2A) Battery Type: 3.7V Lithium Battery Interface: Type-C Port (Input/Output Capable) Charging Current: Max 5V 1.2A Output: Suitable for Low Current Applications Switching: Auto Switching / Permanent Output Indicator Lights: Input/Output Display Dimensions: 4.2V/4.35V Approx.: 16.8*12*4.4mm; 5V: Approx. 16*12*4.4mm Applications: DIY lithium battery charging, small appliance modifications, adding charging ports to tablets, low-power electrical devices Usage Instructions: Connect the module to the positive and negative terminals of a 3.7V lithium battery for operation. The module features built-in overcharge and over-discharge protection; a protection board can also be added to the lithium battery. The Type-C port, solder pads, and rear reserved input/output interfaces are identical sets. Their circuits are directly interconnected, making all three sets functionally equivalent. Wire according to markings (physically connected where colors match). Input can be via Type-C port or direct wiring. Batteries must be connected in parallel, not series. Wires require soldering and should not be too thin to ensure proper operation. Reverse battery connection is prohibited. Function Overview: * When charging current drops to 100mA after reaching final float voltage, the charging cycle automatically terminates. * Maximum charging current: 1.2A. Under proper usage and sufficient power supply, stable charging above 1.1A is achievable. * When battery voltage falls below 2.9V, pre-charging at 200mA commences. * Features a protection board with overvoltage, over-discharge, and overcurrent protection. Over-discharge threshold: 2.9V. * Requires initial power connection to activate the protection board when first using the battery. Precautions: * Do not reverse the battery connection; doing so will burn the board. * Connect the charger before attaching the battery to verify the charging indicator light functions correctly. * Cables must not be too thin, as this may cause insufficient power delivery. All connections must be soldered. * Batteries may be connected in parallel, not in series. Only 3.7V lithium batteries are compatible, with a full charge voltage around 4.2V. * This product is not intended for use as a power bank. Its power output is relatively low, maxing out at 4-5 watts. It also lacks charging protocols. This may cause compatibility issues with certain smartphones. Therefore, when modifying power banks for use with this product, our store assumes no responsibility for any resulting issues with specific mobile devices. FAQ 1. What is this product used for? Answer: Low-power devices, backup power circuits, DIY modifications. 2. Is the input/output switching seamless? Answer: Switching requires approximately 1-2 seconds.

Overall, we had a good experience with the seller We purchased item "1PCS NEW ABB Type AX18-30-10-84 Block Type AC Contactor 110V 50Hz" There was a mix up with our tracking number and another customer's tracking number in the beginning, but this was figured out in a timely manner Then the courier service attempted to deliver our package, but it was after our business hours, so they did not deliver the package on the day it was expected Eventually, items received Have not used items yet
Slight mix-up on the quantity of the order but the seller was very responsive and immediately sent the balance of the propellers ordered along with a sincere apology. Mistakes happen and this seller dealt with it like a professional! I would gladly do business with plc-electric again in the future. Thank you!
Quality new condition perfect value excellent appearance identical this guy got the colour right for me not like some some don’t care and they try to palm you up with anything this guy didn’t he supplied me with what I asked for and I received what I asked for A1 to this guy
