کابل افزاینده 9 ولت

Description:
This DC-DC step-up cable converter can boost the USB 5V to 9V DC and is also very simple, light, and comfortable. With this module, you can convert the common +5V from mobile chargers, power banks, and computer USB jacks to another widespread 9V DC voltage. DC-DC converters come with different prices and size factors, but in the case of this particular model, by limiting to only one function, you save space and cost, such as the cable. Dropping voltage is a relatively easy process, but creating a higher voltage out of a lower voltage almost seems like alchemy. It can only work within the limits of physics, which means the output power (volts*amps) of it will always be lower than the input power (volts*amps).
