USB 5V to 9V DC-DC Boost Converter Cable for Routers, Modems and POS

The 9v-USB-cable is a compact DC-DC step-up converter cable designed to boost a standard 5V USB power source to a stable 9V DC output. This cable allows users to power 9V devices directly from any USB port, power bank, computer, or solar panel, eliminating the need for a dedicated 9V adapter. With a maximum input current of 2A and a maximum output current of 800mA, this boost converter cable provides reliable power for a wide range of low-power 9V equipment.

The cable features a standard USB-A input connector on one end and a 5.5mm × 2.1mm DC barrel plug on the other, making it compatible with many common routers, ADSL modems, wireless access points, speakers, and audio devices. Measuring 1 meter in length, the cable offers sufficient reach for flexible placement of the power source and the powered device. The boost conversion circuitry is integrated directly into the cable, resulting in a simple, lightweight, and cost-effective solution compared to traditional box-style boost modules.

This USB to 9V step-up cable is particularly useful during power outages, allowing users to keep critical devices such as ADSL modems, WiFi routers, and card readers operational by connecting them to a USB power bank. It is also suitable for powering 9V study lamps, small audio equipment, and other electronic circuits that require a 9V DC supply. The cable is an ideal choice for field work, portable setups, and emergency backup power scenarios where a 9V source is not otherwise available.
