Frequently Asked Questions

Check the match between the output voltage (V) and the output current (amperage, A) of your original power supply. The voltage must match exactly, while the amperage can be higher than therequired minimum, but never lower.
Look for UL listing or other safety certifications. Avoid generic, unbranded adapters that lack over-current and over-voltage protection, as these can cause permanent hardware failure.
