1. What is a USB booster cable?
A USB booster cable increases the voltage output from a USB port (usually 5V) to a higher voltage, like 12V, enabling devices requiring higher voltage inputs to be powered via USB. It typically includes built-in circuitry for safety and efficiency.
2. How does step-up converter work?
A step-up or boost converter works by rapidly turning on and off an inductor to increase voltage. The magnetic field of the inductor stores energy when the switch is turned on. The magnetic field collapses and generates a larger voltage output when it is off. Voltage is increased from input to output by this effective technique.
3. Is it safe to use step-up converter?
Yes, step-up converters are generally safe to use. To guarantee safe operation, they are developed with built-in protections such short-circuit, over-current, and over-voltage protection.
4. How does the cable ensure efficiency and safety?
The cable has an internal structure that facilitates efficient heat dissipation, making it safe and reliable for prolonged usage.
5. What materials are used in crafting the cable?
The cable is constructed with a thick copper core to reduce transmission loss, enhance service life, and improve charging efficiency.
