I'd like to power my new AT&T modem/router with 12Vdc (battery).
It comes with a 72W 12Vdc adapter, that has a unique connector.
It's not your typical 5.5mm barrel type connector.
I've done a lot of searching.
Ideally, I'd like to find a cable that adapts the two types.
I've found stuff like 3-pin mini DIN adapter cables, but not 2-pin.
Any ideas?
Thanks.
i've seen that with 3 and 4, can't say i've seen it with 2. if you're comfortable tinkering, and you own the equipment, may open it up and replace their proprietary connector with a barrel to make it more universal

If you cannot find another DIN plug to fit, you can always convert your existing plug so that it will work with either the provided charger or a 12V battery. Of course, if this networking device is owned by your ISP rather than being personally owned, then this might not be such a good idea if you ever have to return the equipment.
I would suggest that you use Anderson Powerpole connectors to make sure the positive and negative connections are never confused. I am an amateur radio operator. Many hams use Anderson Powerpoles to connect their radios to 12 volt power supplies. Since the modem/router power supply is only 72 watts (6 amps), the 15 amp Powerpoles will be more than adequate.
If you go this route, be sure you adequately mark the wiring before you cut it so you do not confuse which wire is which.
The silver plated connectors are crimped or soldered onto the individual wires. Then they are inserted into the housings, red for positive and black for negative. There are YouTube videos that will show the procedure. The housings are designed so they will only fit together one way.
One concern I would have with using a battery to power the device is that you will have to determine which lead is positive and negative coming from the power supply such that the proper connections can be made with the battery. If you connect the power in reverse, it might cause damage to the electronics.
I do not know your specific application, but you might find it easier to either use a Uninterruptable Power Supply to power the charger or connect an inverter to your battery and plug the charger into the inverter. That way, you do not have to cut the wiring on the charger.

There has to be a socket out there to match.
But I looked long and hard yesterday and could find none.
The ISP owns the equipment.
A charger is available on eBay for a hundred bucks!
Perhaps a custom Mini DIN plug could be made up?
I used TalentCell batteries to provide ups power with my last setup, but that was with a separate modem and router with barrel connectors.
Wouldn't it be simpler (and perhaps cheaper in the long run) to just use a UPS?

Call ATT support and ask them to send a new power supply because the one you have "is acting up" so you have a spare to cut the plug off?
That would be my next option. Doubtful they will want to spend the money to have a power brick returned. At least spectrum and frontier never have.

Well, I just got a Bluetti AC180. Pricey, at 600 bucks, for me. My idea is to power a fridge overnight during a power outage. Maybe more, like the garage doors and driveway gate when leaving to get something to eat, or whatever. Mostly, an expensive toy, I suppose.
Anyway, I plugged the ATT Orb and Hubitat into it and un-and-replugged several times. They kept right on running. So, while not a UPS, it could keep things powered, like the TalentCell did.
Now I have to figure out how to keep the thing happy so it lasts more than a year. The Bluetii doesn't seem as customizable via software as the EcoFlow apparently is, but I didn't do much research, so it is what it is.
This looks like a standard DIN connector but with just 2 pins. Maybe an adaption of a DMX implementation
I bought a 4 pin din to 5.5 barrel adapter. It looks like two pins would line up. My plan was to somehow remove the two other pins. However, with the new battery....
without knowing the internal wiring of the adapter, no guarantee you'll be able to power your device
Pins came out easy-rock 'em back and forth, etc.
Polarity matched.
Running on the TalentCell as I type.
Started 4:30PM, with 4 (of 4) lights.
Did not charge it up-it was like that.
Going to let her run to get an idea.
Then try running it with the charger after boosting it up some.
The TC doesn't exactly put out consistent voltage, so fingers crossed.
edit: Maybe see if I can run it down to one bar, or so, and then plug in the charger.
edit2: Couldn't wait. 4 hours still 3 lights. Plugged in charger. Let's see if it gets to 4 bars. Nothing is really warm to the touch.

It got to full charge, 4 lights, overnight, without burning down the house.
Perhaps a cookie baking sheet will be in my future, lol.
I'm calling it a success, but that's just me.
This probably belongs in another thread, lol
