APC - Back-UPS 550VA Battery Back-Up System

I use this is for both surge protection as well as for battery back up for Cable modem, Phone modem & wireless router If you are using a wireless router + an external phone modem like the Vonnage for ex: then the issue is there would be no battery back up for the phone modem. You could still find battery backed-up wireless routers that just covers the router only. If you are using your phone line on your home security system as well then you need to provide a battery back up for the phone modem as well. This unit is good in the sense that it has a strip with battery backed inverter + surge protected output as well another strip with just the surge protection. I have thrown all my home storage network, phone modem, cable modem and the wireless router in this one and so far is working great.

Easy setup, reliable cheap insurance to protect expensive equipment

I live in an area where we get power surges and blackouts every couple of months. With this I don't have to worry that they will mess up my home office desktop and laptop! It gives me enough time to go in and safely shut them down.

This does pretty much what it claims. When the electricity goes out, it keeps the computer running for a modest amount of time. Don't believe the software's estimate however, mine says "90 minutes" and I get about 15. However, this is more than sufficient to finish what I'm doing and go through an orderly shutdown. Believe them when they say the battery doesn't last forever - should be replaced every few years to maintain much hold time. One significant disappointment: we live in the country and have a backup generator (power goes out frequently) and the APC won't charge from generator power - must not be clean or steady enough.

plug and chug, swapped out an old less powerful supply and no problems at all. Worth the $$ upgrade for the extra plugs slots and backup power.

Great product at a good price from BestBuy. These surge protectors are long lasting and will let you know when the battery is going out, but they last really a long time.

Purchased the battery back when my other battery back died. Recommended by Geek Squad guy and it seems to be doiing it's job just fine

APC has been around a long time. Need to be careful where you purchase. Best to buy from a supplier such as Best Buy that moves and sales a lot of these units. Some suppliers sometimes sell older stock and battery shelf life is not the best. Also, watch for sales as you can save quite a bit if your patient.
