“Will this work with an Arris SB33 modem? It has positive polarity & requires 12v, 1.5amps. The plug adapter fits, but the box looks like it provides 3amps for that size. As long as I select the correct voltage, will the amperage adjust to 1.5 or stay at 3”

Thank you for your inquiry! Yes, the Insignia™ - 3,000 mA 5’ Universal AC Adapter for High-Output Devices can work with your Arris SB33 modem, which requires 12V and 1.5A. The adapter provides up to 3A, but the device will only draw the amount of current it needs, which in this case is 1.5A. As long as you set the adapter to the correct voltage (12V), it will safely provide the necessary current without overloading your modem. The adapter's ability to supply up to 3A means it can handle devices with higher current requirements, but it will not force more current into your modem than it needs. If you have any other questions or need further assistance, feel free to ask! Keith | Insignia Support
Sorry, there was a problem. Please try again later.It will only draw the amperage it needs. Get a meter and check the polarity, mine is backwards.
