Just wondering if a 400 watt inverter would work for my pioneer incase i lost power. I was looking at this not to sure if it would work http://www.northerntool.com/webapp/wcs/ ... _200321635
. I like the idea of it already having a battery built in and can switch on automatically when you loose power.
Similar unit from them has gotten decent reviews:
Only $116http://computers.pricegrabber.com/upss/ ... 1/details/
You'll want to shut the convection fan off to increase run time.
Figure 15% loss in the inverter and another 10-15% in the battery. Figure about 1/2 the run time they list. Unless you buy really high end units, you'll never get what they say.
Personally, I'm going to use a couple of deep cycle batts from my camper ($52 at Sams) and a $80 250 watt inverter for my unit, but the auto switch-over would be a nice feature if the power goes out when everyone is asleep.
Check out the Cyberpower, Belkin, APC, etc computer UPS systems. You can get them pretty cheap at local big box stores like Sams, Target, Walmart, etc.
