I Just picked one of these up and I suggest you all do the same if you haven't already!
Recently my friend was on his computer with a few wallets open and POOF, a brownout occured.
The exact definition of a brownout is an intentional or unintentional drop in voltage in an electrical power supply system.
Basically he lost power for for a split second and it somehow screwed up access to his wallets and now he is going through hell to get everything back up and running again.
I bought this Back Up Power Supply for $45.00 at my local computer store and the main function of this unit is to protect your computer and anything you have connected in the case of a complete power outage or brownout.
It will only give you a few minutes to power everything down correctly and safely.
This one I purchased is 450VA/255 WATTS. There are more powerful ones available that last much longer depending on your needs.
Money well spent my friends. JUST DO IT!!
Stay safe, Stay connected.
