USB Power Supply
/This is a really useful device. You feed it power from a USB socket and it puts out a range of voltages from around 14 volts down to two or three. You can also set it to limit the current supplied and it has a nifty display of current and voltage. Great for testing simple circuits and well worth the price.
I got mine here and the customer service was excellent. My first device arrived with the perpsex covers smashed. I messaged the supplier asking if they could supply a couple of spare covers as the electronics worked fine, but they sent me a complete replacement. Good product and good service. Thanks for that.
Note: One thing to be aware of is that the device arrives with the output voltage set to maximum. Make sure that you adjust this down to your required voltage before you plug it into the device you want to power with it.
