NOK 5G21 Gateway Battery Backup

There is a plug receptacle on the device labeled UPS

Does anyone know what type of UPS and/or plug can be used with this?

The battery in the device is primarily used to assist you in locating the best place to put it. If you're really dependent on this, I would advise getting an Uninterruptible Power Supply.

It seems that it is more efficient to use a 12VDC UPS, versus 120VAC UPS, then additional conversion loss from AC-DC adapter. The link to the APC UPS above shows as unavailable. Here's a link to something that seems to work, but doesn't include the battery.

Here’s another version of the above on Amazon that includes the battery:

Looks like it uses a 12V 7.5AH battery; should last for about 3 hours at a draw of 2A but others have reported between 1 and 2A. Probably 3A if it is charging the interal battery too.

I wonder, if ever, will TMO allow the internal battery be used for both WiFi and Cellular during a power outage.

NOTE: buyer beware, I'm not suggesting buying this, just as an option. I would be best to buy something new with at least a 2-year warranty.

Update on APC UPS Back-UPS Connect:

After charging for about 10 hours, I was able to stream Netflix movies for over 10 hours. I was hoping for at least 2 hours because that is the longest Zoom meetings that I need to attend from home. 

 

 

Can you please provide more information as to which APS this is and how it is connected.  That information would be much more helpful for this group.

dilbert: the link was in the post prior to the picture you replied to. However, *that unit* shows as unavailable on Amazon, which is why I provided some additional options. However, if anyone finds any additional devices (12VDC UPS), that would be great, especially if they are cheaper. Also we need to know if the router requires a 5.5x2.5mm or 5.5x2.1mm or another size (I have no way to measure the ID). Seems 2.1mm inside is more common than 2.5mm but adapters may not be difficult to find.

The battery is intended ONLY for finding best signal location during initial setup, or perhaps retaining circuit power during short duration power surges.

This was poorly to not-at-all documented.

Agreed; the previous 4G-LTE device had a battery which maintained WiFi connectivity during power outages. This functionality didn't carry over to the 5G cylinder device from Nokia. Many of us, including myself, relied on the built-in battery backup for power outages lasting on the order of minutes to hours, for things like ring doorbells or NAS devices (Plex) using UPNP (neither of which are supported by this 5G device).

Just found this one at Amazon:  https://www.amazon.com/dp/B089SQFCBW?psc=1&ref=ppx_pop_dt_b_asin_title

I've had it plugged in to charge overnight and plan to test today.  It comes with several adapters for the plug.

Installed the battery backup yesterday and so far seems to be good, easy solution.  It comes with two cables and multiple adapters.  One cable works directly from the 12v/3.5a plug to the gateway.  This unit replaces the gateway's power supply and provides the 12 volts directly.

Could you post some pics?

Link to where to buy?

Gracias

Purchased it from Amazon here:

I need to take a few pictures and will upload soon.
