I've found that a lot of wall-wart chargers deliver dirty power. They are typically used for just charging batteries so it doesn't matter if they produce spikes or DC in pulses.
I'm using this inexpensive DC-DC converter to clean and step down the output of my wall charger; http://www.amazon.com/gp/product/B008BHAOQO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 They are small, only about $4 shipped, and they will take a wide range of input voltages and step it down to whatever you want as clean DC power. -- You received this message because you are subscribed to the Google Groups "ioio-users" group.
