How long will the battery last in a power outage?

That really depends on the amp draw during the outage. You'll need to define how much power you are pulling. Generally these are designed to keep computers and sensitive equipment running just long enough to properly shut them down. If that is what you are using it for you can reasonable expect 10 minutes. I've never tested it to see how long it would last with my setup. Hope this helps.

I believe I read 12 to 15 min depending on how much amperage is being drawn, we have two power outages a week as we run on generators and need to change oil weekly. Sometimes down 5 min and have had no problems. Its really so you can shut down without any loss of work. Hope this helped you.

Depends on how much power you are drawing. I have my desktop PC, monitor, router and cable modem on battery backup. All I want is time to save what I am working on and shut down properly. Around 10 minutes would be fine with me, but I haven't tried to test it.

Depends on how many times you push to use or just to scare someone. My has lasted up to 24hrs. With me just playing around and setting it off for 4 or 5 hrs. and I still had charge next day.

Part of this answer is going to depend on the quality of battery you buy. here is my experience. I used Energizer batterys for the week of my vacation. The radio was on for about three to five hours for five days (20 hours or so) When I got home I took the batterys out and went back to using the cord because the radio stays in the house. i tested the batteries and they still showed an almost full charge so I put them with my spare flashlights. I would guess that the batterys would have lasted better than twice the time I used them for.

Hi!I still haven't used it. I have it stored away in case the power goes out.

Officially, up to 4 hrs. and 45 mins., but my experience would suggest less than that, somewhere in the neighborhood of 3.5 - 4 hrs. before getting a low power alert.

The batteries are meant as a backup in case power fails as I believe it often does in case of fire. In my house I've rarely had a power outage so I'm not sure how long these units would work on battery power alone. I replace my batteries every year.

Hi. The battery Will run for about 5+ hours if you are using the power saver configuration and you are just browsing or using Word. Any heavy use (vídeos, streaming, large databases, etc) and the battery Will last for about 3 hours.

The battery is a CR2032, 3v; about the size of a quarter. Should last very long since "on" time is quite short; depending on usage however.

The unit is hardwired to your household power. The battery is for back-up incase of power outage.

It should work for that long. It works better plugged in. I wouldn't leave it going for more than 4 hours with good batteries.

It totally depends on what you have attached to it. For me personally, I have 4 micro-ATX (low power) servers, and a Cisco business-class switch attached. If the power goes out, it will last for around 20 minutes give or take. For most power outages that are brief, utility power kicks back on before the battery runs out.

It has a battery backup in case the power goes out but not sure how long that will last for

probably about 3 plus hours -we use it for travel so it is usually being plugged in every night or during use. Never have had a problem with too little battery.

the battery is for backup only..... in case electricity goes out. You still need to wire it.

Depends on the load, mine will go probably 15 min irl. If you're gaming online and the power goes out for a minute or two and comes back you will not be interrupted. But keep in mind these units are made for short term power backup so you have time to shut down without damaging your computer.

I have mine plugged into an electrical socket all the time. I bought it for when there is a power failure at night. When the house power goes off, the flashlight will turn on. Not only will I be able to find it, but I will have light on high for around 2 hours and if I keep it on night lite setting it can last up to 15 hours. For $7.99 it is a great device for safety when emergencies happen. I am not sure how long it takes to charge from the dead state as I have always kept it plugged in since I received it.
