One caution about these switchers. Many of the cheap switchers being
made today both as chargers and supplies generate tremendous amounts of
RFI. A number of my ham friends have experienced unbearable
interference from these devices. Note that they have no part 15
certification and you can never locate the actual manufacturer to have
problems corrected. It gets even worse when your NEIGHBOR has these devices.
