What devices should you use to protect valuable electronic equipment from potential power problems? You will need different products depending on what you need to do. Do you need to convert 220 volts to 110, or just adapt the outlet? Do you need to shut the power off when the voltage fluctuates or regulate it to ensure a constant 220? When thinking of surge protectors, don’t forget to protect your devices from surges coming through phone or ethernet cables. More about power problems. View as a PDF.
