Question 1

My husband needs battery back-up for his cpap machine. Will this work for his situation? We have frequent power outages in our area, and we need something that will work for 7-8 hours at a time between charges. Thank you.

Accepted Answer

Probably not. I'm guessing the cpap machine might be rated at perhaps 50 watts. Disregarding any power quality or peaking issues, assuming 100% efficiency for the UPS's power inverter (definitely NOT possible), and using the full 3.5 amp-hour capacity of the UPS's battery, this would result in something less than an hour of operation. In reality, I'd be surprised if you could even get 30 minutes. Your best bet is to contact the cpap manufacturer and get a recommendation from them regarding the necessary UPS rating.

Question 2

I want to use this for garage door opener, 1/2 hp belt drive.  I believe this will work for unexpected power outages on short term basis.  Is this the correct unit for that use?

Accepted Answer

No. You should not rely on this for emergencies like that. It only has enough battery power to run a small computer and monitor for a few minutes, so you can shut everything down properly.

The drain that a garage door opener (and the indoor garage lights attached to it) would put on the battery would probably be too much. The battery would last long just enough to get the door half-way open...and probably not be able to close it again. And that's assuming you used this as soon as the power went out.

Garage doors have manual "release" cords you can pull to open them if you lose power.

Question 3

How long will the battery last?

Accepted Answer

Usually it depends on how much equipment is plugged into it and how much amperage draw each piece has.  Most of the small backups are designed to give you around 15 to 30 minutes of battery life.  Keep in mind that these are designed to give you enough time to save and close your work not work and play for long periods of time.

Question 4

how long do the battery's last when the power goes out?

Accepted Answer

I am using this only for backup power for our router at church. All I'm trying to do is keep our external IP address from changing when power company power outages occur, because we're using remote access for one of our internal computers that controls our electronic message center. If I wasn't so cheap, I'd pay for a static IP address. So far, we've weathered every outage. I don't know how long the longest was, but according to the power requirements of our router, the battery should easily last an hour. This unit would probably by OK for a computer, but only if you were at the keyboard when the power went out, and you could timely shut things down.

Question 5

what is the difference between the UPS back up 350VA, 550VA, 650VA?

Accepted Answer

The difference is the amount of battery powr.  The 350 has less power than the 550 and the 650.  The less the power the less the amount of time it will runa a given device if their is a power outage.

Question 6

what is the battery run time ?

Accepted Answer

That depends on how much power in Watts the device you are powering will pull from the battery backup. These devices are about the smallest  capacity in terms of run time. I use them to power very low wattage devices like routers and switches to make my customers networks more reliable. I think I would look at a bigger unit for a computer workstation.

But to specifically answer your question:
1. Find out how many watts the device you want to power requires. You can usually find this in the documentation, a sticker on the unit or spec from online. Google is your friend.

2. Go to the APC runtime chart for the BE350G at 
the APC website. Sorry I had the link here but NewEgg won't allow it.

So if you determine you device needs 50watts the chart shows you will get about 16 minutes of runtime. 100watts gives you 6 minutes, 200 watts yields 1 minute. If that is not sufficient for you, then just go further down the chart and you will be able to figure out which model APC UPS might be a better fit. Hope this helps

Will.

Question 7

will it run the exhaust fan on my pellet stove ?

Accepted Answer

It should.  I have no idea the current draw than fan would require but this should work.  It will beep if the battery goes bad.  I would not plug a lot of items into this.  350VA is pretty low.

Question 8

Does this have mounting brackets on the bottom so it can be wall mounted?

Accepted Answer

No. this product does not. There are places for the anti skid pads underneath. That is it.

Question 9

What is the runtime of Back-Up?

Accepted Answer

It depends on the load- what you have plugged into it. If you have a desktop computer and monitor plugged in not long- guessing 5- 10 minutes, tops. If you're using it for equipment with a lower draw, like a network switch or modem, then much longer, maybe 30 minutes. But the battery life when the power goes off depends completely on how much the equipment you have plugged into draws. Larger and more expensive battery backup units have bigger batteries, and last longer in addition to superior power conditioning. Just remember battery backups really aren't to power your equipment for long periods- they're intended to give you time to shut down gracefully.

Question 10

without giving specs for my wireless router/modem (as I don't have them), any very rough idea how long your BE350 would keep it going, if nothing else is plugged into it ?  I'm worried the power will go out and I wouldn't be home to see the sump pump isn't working.  I have a device on order that will call my cell if it detects water in basement, but won't work if router is not powered.  Just a very rough idea will do.  Thanks

Accepted Answer

That depend the total watts on all the devices you connect to the battery plugs.

First you find the wattage of each device. This is usually is in full manual under specification and under power or u might fine it on the power adapter.

Second you add all those number up.

Third u divide the 200 watt(battery storage power) by the number on step 2. This give u number of hours the battery can support your devices.

For example, if u have 2 devices that uses 15 watt and 5 watt on battery plugs. Your total usage is 20 from step 2. Then from step 3, 200/20 is 10. So you kinda expect everything should work for at lease 9 hours and kinks risky after that.
