What are the voltage and current ratings?
It outputs 12 volts DC at 1 amp. What is the plug size for this adapter?
The barrel connector is typically 5.5mm outer diameter x 2.1mm inner diameter, center-positive. Can I use this with a device that needs 12V 2A?
No, this adapter provides only 1A—underpowering may cause malfunction or damage. Is it safe to use with non-Netgear devices?
Only if the voltage, current, and polarity exactly match the device requirements. Is the adapter UL or CE certified?
Most genuine Netgear adapters are UL listed and CE certified, but confirm on the label. What’s the length of the power cord?
Typically, the cord is about 3 to 5 feet long. Can this adapter work with international power outlets?
No, this is for North American 110-120V AC power input unless specified otherwise. What is the model number printed on the adapter?
The model number is 332-10992-01, which may also include a revision letter. Will this power a Netgear CM500 cable modem?
Yes, the CM500 is known to be compatible with a 12V 1A power supply like this one. What happens if I use a 12V 1.5A or 2A adapter instead?
A higher amp rating is safe if voltage and polarity match; the device only draws what it needs. Is the polarity center-positive or center-negative?
This adapter is center-positive, which is standard for Netgear devices. Can this adapter be used outdoors?
No, it’s designed for indoor use only. What are the dimensions of the power adapter?
It’s compact—approximately 2.5 x 1.5 x 1 inches, not including the cord. Is there a fuse inside the adapter?
Yes, it includes internal safety protection such as overcurrent and short-circuit protection. How can I check if the adapter is working?
Use a multimeter to test voltage output, or try with a known working device. Does this power adapter work with Netgear Nighthawk routers?
Only certain models; most Nighthawk routers require higher amperage, like 12V 2.5A or 3.5A. Can I buy just the power adapter without the modem?
Yes, this adapter is sold separately as a replacement accessory. Can I use this power adapter for other brands of modems or routers?
Yes, if the device requires 12V DC, 1A, and uses a center-positive barrel connector of the same size.
