SparkFun Hydra Power Cable

by Sparkfun

The Hydra breaks out the 5V and GND lines from your USB power supply, computer or otherwise into three connectors: Barrel Plug, JST and alligator clips!

Behold, the Hydra! This USB power cable probably looks a lot like something you've hacked together before. We do it all the time, because what is a computer if not a 5V power supply that happens to run software?

The clips are shrouded to avoid shorts and the barrel plug is center positive. The cable is 6 feet long overall which give you plenty of room to work.

Remember that USB power does have its limitations. Most USB hosts will only provide between 100 and 500mA at 5VDC.

Used this to power a neopixel project so I can just splodge it into a USB adapter and it'll get power. It works really well, the connectors are solid and it's a decent length cable. I'd love to be able to wrap up the crocodile clips fully so while I'm tinkering I don't accidentally short them, but a bit of masking tape sorted that.
