    I charged the device for a day and plugged it right in and it worked. There are separate sides for with battery backup and just surge suppression. The outlets are a decent so the larger plugs still fit.

    Small electronics insurance that saves your TV's

    We just love having this protection working for us daily. We use these on all of our TV's and other electronics that could be damaged due to power surges. These backups condition the power, this helps save most equipment from brown outs too. If we lose power it helps us have time to shut down our equipment with 10 minutes of running time, like for your computer also. Try these and one time when you need it, you will see the light and hook these to each sensitive equipment items.

    I love it. It has no flaws, and it has an extra battery, so if the power does go out, I can safely turn it off properly.

    I have several of these attached to various electronics. I use them mostly as protection against the poor power that the power company provides.

    Perfect for Cable Modem

    I purchased this to be the battery backup for my Cable Modem. It works perfectly for this and should easily keep it up and running for 30-45 minutes if I lose power. I sadly lose power for 10-15 seconds at my home at least 1 every month or so and this makes things easier. I highly recommend this and would buy again. If you look I did... I bought this the 650 and the 1500 model for other uses in my house.

    A UPS should be considered a necessity in this day and age. Whether it's to protect your devices from spikes, brownouts, or generally "dirty" power, you're doing yourself and your gear a favor by having one of these.

    Does exactly what it needs to do at an affordable price! I am using this for my router and modem to help protect them in power outages. For the price you aren't going to get much better and it does everything it needs to do.

    Definitely a must grab item to protect any computer set up or gaming set up from brown outs and black outs. Just a week into getting a new computer set up had a surprise black out, and power dropped. I was able to safely shut down my computer with the time this gave me and I didn't lose the projects I was working on. Worth the price for what it does.

    Life saver. We were having a lot of rolling brownouts in the summer. I hooked this up to our model and router and it was a godsend. Kept our internet up and going despite not having power.
