Frequently Asked Questions
No, the RP190 requires a DC 9V power supply, this is AC and incompatible.
Yes, the Intellifex’s power requirements fall within the 2.1A range, but monitor for any unusual noise.
While generally reliable, repeated power cycling can stress any adapter; consider a higher-end, isolated unit for frequent use.
