9V DC Battery to DC Plug Cable
Power your Arduino or other device with a 9V battery using this 9V DC Battery to DC Plug Cable from PMD Way.
Look, stop now. We will sell you one of these - however they aren't the best at all for powering things. Why is that? Your average 9V battery has a capacity of around 310 mA (Duracell Coppertop 216).
So if your project draws 100 mAh at the DC socket - the battery will last no more than 3 hours - or less, as the voltage drops towards end of life.
Instead, please consider the 6 x AA cell holders in our Arduino power collection. You'll get a lot more life from your battery doing it that way. However if you really want one of these, we'll sell you one.
