Q: Does this adapter work with devices that require a round-pin connector?
A: Yes, this adapter comes with seven interchangeable tips to support devices that need round-pin connectors.
Q: How do I know which voltage is selected on the adapter?
A: The adapter has illuminated LEDs that display the selected voltage.
Q: How long is the cord attached to this adapter?
A: This adapter has a 5 feet long cord.
Q: What is the maximum current output of this AC adapter?
A: This AC adapter has a maximum current output of 3 amperes.
Q: Can I use this adapter internationally?
A: Yes, you can use this adapter internationally as it supports 100-240V input at 50/60 Hz.
A: 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
Q: Will this work with a samsung G3 odyssey 27 inch monitor?
A: The Insignia™ 3,000 mA 5’ Universal AC Adapter for High-Output Devices is designed to support a wide range of devices with various voltage and current requirements. It offers adjustable voltage settings from 3 to 24 volts and can provide up to 3,000 mA (3 A) of current. To determine if it will work with your Samsung G3 Odyssey 27-inch monitor, you need to check the monitor's power requirements. If the monitor's voltage and current specifications fall within the adapter's range (3-24V and up to 3A), then it should be compatible. However, it's important to ensure that the connector tip matches the power input of your monitor. If you have the specific power requirements for your monitor, I can help you verify compatibility more precisely. Let me know if you need further assistance!
Q: Will this adaptor work for a sound bar listed with input of 24V and 3.4A ?
A: I think it won't work for what you need. This power supply outputs at 2A when set to 24V. You need one that is at or near 3.4A.
