I need to use this device without having AC power. Can you share details about the 12V DC requirements?

When I get home I can check if there are any labels or something in the owners manual. My guess is very, very nominal

You could use 12 VDC power (like a battery) to power the controller and the fan is then powered by the controller.

No external power required. Only needs a USB port with enough power. Most standard USB 3 ports should be adequate.

Require power source of 12v DC. Could run on a 12v rechargeable battery pack not sure how long depends on battery pack.

Hardwired 12 volt DC and therefore not suitable for home use. You would need something for 120 volt AC current.

You would need the AC to 12 volt DC adapter. It can't be used with a normal 120 or 240 volt AC outlet on its own.

Out of the box it is only 12 volt DC. You need to purchase an adapter to connect to 120 volt AC.

same answer as Nancy N.(5 volts,500mA,DC).Best purchase I've made-small,portable,etc.You really can't go wrong.

You could use a 9v battery however you'll need to run it through a regulator. The device runs on 5v. You can get a nice 5v power supply here on amazon for around $15 and that you can power with AC.

This unit comes with a DC 6V 500mA plug in. It also can be run using 4 - AA Batteries.I hope this helps.

No, unless you plan to supply it 12 volts DC, you will need to buy a convertor that should be available on Amazon

You'll need a power invertor to go from the 12VDC a car has to 120VAC the device needs. But basically the answer is no.

Thanks...i used a small 5v USB charger and powered it from my switched AC source. I just don't see where anyone mentions you need an independent supply of 4 to 30 V to run the meter. I was planning to use the power supply I was building into a case with the meter to show voltage and current being used by the connected devices.

It's made to run off a computer power supply, but any 12V power supply should do.Rated Voltage: 12V DCStart Voltage: 8V DCOperating Range: 8V~13.8V DCRated Current: 0.2 Amp @ 60℃ / 0.08Amp @31℃Rated Power: 2.4W @60℃ / 0.96W @31℃

Does not require batteries. I used it in a low voltage application to turn on/off LED light strip. My power source was a 100-240V AC input to 12V DC output power adapter.

Yes it is a safe bet this unit is going to need power to do it's magic. So if you can shoot 12V dc out of your fingertips, you're all set. If not, the adapter will the way to go.

The AC adaptor is not needed, it use the power from the USB3 which is adequate. However, it does have a mini DC plug that use 5 volts if you have to use the adaptor. I do not use this plug at all for this device or any other device that using the USB2 or USB3.
