This indicates support for Quick Charge 3.0 protocols with a maximum output of 18 Watts . This allows the device to function not just as a vehicle emergency tool, but as a high-speed power bank for smartphones and tablets.
The hardware core of a board stamped with Cjs02-qc18w-v1.3 is engineered to bridge high-amperage output requirements (like cranking an engine) with low-voltage step-down logic (like charging a phone). Component Parameter Specification Purpose / Functionality USB Type-C (5V/3A, 9V/2A) Rapid replenishment of internal lithium cells. Output Port 1 (USB-A) Qualcomm QC 3.0 (18W Max) Variable voltage: 5V/3A, 9V/2A, 12V/1.5A. Output Port 2 (USB-C) Bi-directional PD / Smart 5V Output Universal compatibility with smartphones and tablets. EC5 Jump Start Terminal 12V DC Native Pass-through Outputs peak currents for engine cranking. Voltage Range Tolerance 3.0V – 4.2V per cell bank
: The "QC18W" designation confirms it supports Qualcomm Quick Charge 3.0 standards, providing up to 18W of power through its USB-A or USB-C ports to rapidly charge smartphones and tablets. Cjs02-qc18w-v1.3
: It manages the transition between the high-amperage jump-start port (direct battery access) and the USB outputs (regulated 5V, 9V, or 12V). Key Components & Features
Whether you require for passengers. Share public link This indicates support for Quick Charge 3
The v1.3 layout incorporates dedicated onboard hardware protection circuits to safeguard the battery cells and connected electronics:
Long-term feedback across retail platforms reveals that consumers appreciate the durability of the platform compared to generic, unbranded gas-station chargers. EC5 Jump Start Terminal 12V DC Native Pass-through
: Capable of jump-starting 12V vehicles with a starting current of and a peak current of Safety Protections : Includes "safe and smart" features like polarity protection (prevents damage if cables are reversed) and overcharge protection Power & Charging Specs 18W Quick Charge (QC18W) : The "QC18W" in the model name indicates support for 18W Fast Charging for mobile devices. Multiple USB Ports : Features 4 USB ports
Locate the HT7550-1 chip on the PCB. Check the voltage between its output pin and ground. If the input pin shows battery voltage but the output pin reads 0V, the regulator is blown and needs replacement.
In the year 2157, in a world where technology had advanced beyond recognition, a top-secret research facility known as "The Citadel" had been working on a mysterious project codenamed "Cjs02-qc18w-v1.3." The project was shrouded in secrecy, with only a select few privy to its details.
