Review: Nice little UPS, good for what it is intended to do. May need a bigger power supply. - Got this thing to keep my landline working through power outages. I am using it with a Nokia G-240W-G ONT which is not on the list but the included adapters fit. Charged it fully for 24 hours then did a runtime test to see how long it can run my ONT. Not sure why some reviewers won’t do this but it’s the only way to know for sure the battery life for your setup. I got 19.5 hours of battery power before I decided to end the test. I can get more than 30 hours if I turn off WiFi and ethernet attached devices. That was quite a feat compared to some 4-5 hours of runtime from a regular APC 1000 VAC UPS running the ONT alone. My big recommendation is to get a power supply at least 2 amps. More is better. When I wanted to do the initial charge I first tried using a 1 amp power supply and that didn’t work. Had to use a 2 amp power supply and fortunately my ONT also uses a 2 amp power supply. It will take a long time to charge again after a full discharge. Mine is only up to two LEDs after 5 hours of charging after the runtime test. But in general I recommend this device. I only wish the output cable was longer. April 16, 2024. Update after 11 months of use. Other reviewers warned about the need of a higher amperage power supply for better results. They are right. Three days ago we had a 3-hour outage which does not happen often but is not uncommon. I decided to take the opportunity to do a run time test after almost a year of use and disconnected it from the power source before power returned. In general little or no capacity has been lost and the thing is still capable of powering my fiber optic ONT longer than 24 hours. However, three days later the thing is still charging, fourth light still flashing. And it didn't take longer because yesterday I powered off the ONT while I was out for work. The 2 amp power supply that came with the Nokia ONT is adequate for normal use and keeping the UPS topped off but definitely not enough to charge the UPS and operate the ONT at the same time. This was the first time since the initial test that I have discharged the UPS so I had not noticed this initially. Already ordered a 5 amp power supply as recommended by another reviewer.
Review: Compatible with Motorola MB8600 and Netgear Orbi RBR/RBS 850 Routers - Living in an area where I need to rely on WiFi Calling capabilities due to poor cell signal and working from home, I need to be able to have my internet and router last as long as possible during a power outage. I ordered two of these to use on my Motorola MB8600 cable modem and my Netgear Orbi AX6000 RBR850 router. Before ordering the APC UPS Back-UPS Connect, I had both modem and router connected to my APC Back-UPS Pro BR1500G (which my PC is connected to as well). I was taking a chance since these two products are not listed as being compatible. I did confirm their max power consumption is less than the limits of the UPS, so the gamble was if the connectors would fit. The provided adapters that come with the APC Back-UPS Connect do work with my modem and router, requiring no additional purchases. Due to the power requirements of my PC, which is left on 24/7, there isn't much runtime to keep my internet and WiFi running during an outage. My current UPS is mainly there to sustain power for short outages and to perform smooth shutdowns, maybe 5-10 minutes of power for the PC and all other devices. If I know to expect an outage (e.g., a severe storm) and I turn the PC off, I might be able to get about 2 hours of power for the internet and WiFi. The modem (MB8600) is rated for up to 30w of consumption but information online shows it averaging less than 10w. The router (RBR850) is rated for up to 37.8w under max utilization, but is documented by the manufacturer to be averaging closer to 8.5-12.5w in day-to-day use. Using the APC Back-UPS Connect, one for each the modem and router, I am hoping to achieve far longer runtimes (closer to 10 hours or more based on APC's documentation), which should be ample for most extended power outages that I tend to experience in my area. The APC Back-UPS Connect is nice and compact, which is a plus, making it easy to place near the devices. If I had any negatives, it would be that the built in cord that connects to the modem/router is shorter than I would prefer, which means the APC-Back-UPS Connect needs to stay relatively close, making it harder to hide away. If I had any other suggestions for improvement, it would be nice if it displayed estimated runtime instead of just a 4 bars that each represent 25% of battery capacity. I am extremely happy with this purchase. If only I knew about it sooner. I'd definitely recommend to others to consider adding one (or two) for their modem and routers.

## Questions & Answers

**Q: Look's like the ups device has only one 12 output. would a 1-2 outlet adapter work for my 12 volt modem and router?**
A: ups is designed for low power devices less then 38.4 watts and will shut down if load is greater then 38.4 watts ,  output voltage is 12 volts dc plus minus 5% , current 3.2 amps , information from instructions. answer is a maybe

**Q: The ups has 5.5x2.5 mm connectors and adapters to 5.5x2.1 and 6.5x3 mm. are adapters to 3.5x1.35 mm available anywhere?**
A: Various adapter plugs are available from Amazon.  You need to know the ID (socket inside diameter) and OD (center pin's outside diameter) of the device you want to plug into and the ID and OD of this power plug.

**Q: Can the output from this be stepped up to 48 volts using a dc-dc transformer?**
A: The problem is that a DC-DC converter consumes power itself, which will reduce the amount of power available and further reduce runtime,

**Q: Has anyone used this with a fios ont?**
A: I tried but the plug isn’t compatible. I also did more reading and from my understanding, adding battery backup to the ont only supports Verizon voice, not data.

### ⭐⭐⭐⭐⭐ This 12v UPS is such an awesome device.
*by T***7 on June 27, 2024*

I use this to power my Xlink BT HD Bluetooth adapter for my cell phone to power my landlines hooked up to it when the power goes out. It does not come with a 12v adapter, it uses the 12v adapter from your device to power it then you plug you 12v device into the UPS. I simply plugged this into the adapter and it took right off. I let it charge for 24 hours and it works beautifully. This is the most intelligent UPS APC has ever made. I have three of the traditional UPS APC makes and they do make a great product. They work good and are hassle free. I just wish they would make a UPS without the 120v ac outlets and made one just for hooking up DC powered devices into. Why charge a large internal battery only to have the DC stepped up to a 120v ac output then plug in a transformer and step it back down to DC output to power your 12v DC device? APC, if you're reading this review, please consider it. Will add photos soon.
