Power Interruption is a hazard. To overcome the problem I suggest using a device called a UPS (Uninterruptible Power Supply). The device is two-fold as it protects from Surge Voltage and also supplies AC Power to appliances or electronics when the power to your residence is lost.
All UPS Units contain a rechargeable battery that kick-in within milliseconds of a power outage. The electronics connected to the UPS will never loose power for a given period of time.
The work load or Wattage is dependent on the UPS Rating. The UPS can be an inexpensive unit that last 15 to minutes, up to 1200 Watt systems that last hours. Naturally the high wattage units cost a great deal, however, they are worth every cent if a sensitive device has a chance of failure.
I have a 1000 W UPS and that maintained my incubator for over an hour when my power was out a few weeks ago. I also used a UPS as power backup for my Laptop Computer, another for the Radio and small TV, a UPS for my Internet Modem ( signal was available) and another for a Lamp. As you can see, I have several UPS devices available and when the power returns they all regenerate back to full back up storage.
Any Question? Feel free to contact me accordingly. Lauren
