GL-X3000 voltage difference?

I got a GL-X3000 and would like to connect it directly to the 12V electrical system in my motorhome (Fiat Ducato model 2019). Is this possible or do I need a voltage converter?
How much voltage difference does the GL-X3000 work without errors?

Thanks for replies

You’re good with a direct connection to your 12v system. The X3000 accepts 9-36V. The prototype case for the X3000 actually had 9-36V DC written on it, but GL was concerned that it would confuse consumers.

See the response from GL.iNet in this thread : GL-X3000 Spitz AX input voltage range

And, FWIW, I have my X3000 connected directly to the battery in my trailer and it works just fine.

Thank you very much for your quick answer, which completely answers my question

Did you connect your x3000 directly to 12v in the motorhome? Does that work for you? I did it and have always a offline modem all the time…

Could you let us know how you connect X3000 on motorhome 12V DC? A picture showing it would be appreciated.

To help our customers to connect with motorhome battery easily, we are preparing some power cable samples, showed as below picture, 1 meter power cable with 3A fuse. And we can sent one sample to you after the samples are ready.


Unfortunately I can’t take a picture of the installation, because otherwise I would have to dismantle the panel again, but it was connected with so-called “Wago clamps”!

Thanks for this information. May I ask an addtional question? Do this Wago clamps already exist on the vehicle, or if we supply such Power cable, it’s better the Power cable with Wago clamps ? Thanks.

You can buy these Wago clamps at our hardware store in Germany! Some motorhomes already have these, we had to buy them! I still have a picture of the installation! However, I’m wondering, I had problems with the built-in modem in the router, it was always online and then offline again, an colleague from gl-inet wrote to me, that I an only use the original power supply with 230V, otherwise the router would not working correctly??? Since I installed the beta firmware (Saturday December 30th) I haven’t had any more failures!

Thanks. X3000 can connect with the power on vehicle, but need to assure the DC range is 9~36V, while XE3000(with embeded battery )only supports 9~16V. And the maximum power consumption is ~20W, i.e. ~12V/2A.

If you still meet offline issue, we will analyze it. Thanks a lot.

Okay, then I’ll test some more and let you know if I have a problem again!

I have connected my X3000 directly to my RV 12v wiring (it is a constant 13.6 volts) and have no issues with connectivity. It’s been wired this way for a few months now.

Hi Thomas,

Good to know.
How did you connect the router to 12V?

I just snipped the cord that came with it and installed spade connectors so that I can easily switch between the wall wart and the hard wired 12v connection if I need to make it portable for any reason.

Modem is always offline, it runs stable for a few days and then it fails, so I always have to unplug the router! Don’t any of you have a problem like that? I have O2 Germany as a provider!

I would also need one for my new motorhome. How could I subscribe to this and get one when you’re ready?

Please send me you shipment address, we will ship one sample for you.

After you used it, please help take a picture and tell us your feedback for this power cable.


Thanks, I would be happy to provide feedback!

I just made a recent order of GL-X3000 and refurbished Beryl from you and they are arriving today and my order number was #EU9826. I wasn’t able to register to forum with the same email as I used in the purchase so they are different.

Can you check my address from that order so I don’t need to share it publicly?
