## Overview

The Step Up Voltage Converter is a versatile 5V to 9V/12V USB to 2.1mm DC booster cable, measuring 1.2 meters in length, designed to enhance your device's power capabilities with efficiency and ease.

## Description

This cable is kinda fascinating - it has an integrated boost converter, so you can plug it into any USB port (from a computer, battery pack, etc) and it will give you a higher DC voltage! It's a handy way to power 9V powered devices with a center-positive 2.1mm DC barrel jack from a USB port. We also have a version that provides 12V, and if you just need a passthough cable, here's one for 5VDC. These are rated at 500mA output, but you can go a little higher, we pulled 700mA and we got a little voltage droop but it worked fine. Probably best not to draw 700mA continuously though! Here's our measurements for various current draws when we set our bench supply to provide a steady 5V voltage 50mA (9.0V output), 100mA, 90% efficiency 100ma (8.95), 205mA in, 87% efficiency 200ma (8.9V): 410mA in, 86% efficiency 300ma (8.8V): 620mA in, 85% efficiency 500ma (8.8V): 1060mA in, 83% efficiency 700ma (8.8V): 1550mA in, 80% efficiency So, overall there's a 90% efficiency at low current draw that drops do about 80% at high current use. There's also a 3 mA quiescent current. Note that often times the USB port voltage can droop too, and in addition you may have power losses with any thin or low quality cables with high resistivity!
