Lower cost units either do not provide the power required (Laser Printers make a huge power draw when they are warming up), or they don't provide adequate protection or the printers electronics (e.g. they are not providing enough surge protection).My notion was that a battery backup with AVR might be able to provide sufficient power to the printers for the milliseconds that the laser is warming up, while also protecting against brown-outs and surges (my local power is prone to both)

If you really care about surge protection for your internet coax cable, plug it in during a storm and deal with a potentially slower internet speed

It has generous capacity with five outlets for both backup and surge protection and five for surge protection only

It's a smaller unit, the screen can be turned off (good if it's in your bedroom), and it's one of the few devices that actually allows/maintains 1Gbps negotiation on it's dataline surge protection - despite others being rated for it

This is the best you can have for home use backup power & surge protection

You can get less expensive aftermarket Chinese batteries, almost as low as $29 a piece, but would you trust your equipment to those?It also has surge protection for coaxial cable and network cables that you run through your modem

For our touch-screen computer, this provides enough backup power and surge protection to keep our minor investment running.

As always, APC provides solid and dependable backup / surge protection for expensive electronics.

The only comment that I have regarding the instructions is that it should have made it clear that there are two banks to plug in your devices and that one bank for plugs only provides surge protection and no battery backup so you have to be very selective about where you plug into the UPS.

This is an excellent Ups and handles all my battery back up and surge protection needs without driving me nuts with background noise especially alarms from faulty power or whatever sets the alarms of on the ups.

When it went dead, I discovered that it was hooked into the surge protection bank and not the surge with battery backup.

Easy installation of unit and software with plenty of battery/surge and surge protection outlets

Used for battery backup and surge protection

I decided to use the coax surge protection feature because the UPS was conveniently near my modem

Anyway, the backup was and is very useful because I have frequent blackouts and also the surge protection had to intervene frequently as the voltage is rather instable

n’t loose any

n’t loose any

It was pretty easy to install except that I had some I/O conflicts (not the fault of the UPS unit but the OS

Works just as I
