Using Power Inverters Connected to a Lead Acid Battery to Run Appliances.

Question about the Cobra Cpi 2575 - DC to Ac power inverter - 2.5 kW or the Go Power 2500 watt inverter.

Q: "hi, i am interested on your Cobra Cpi 2575 - DC to Ac power inverter - 2.5 kW Item Code WTCPI2575 or a similar model by Go Power. i was wondering if it can run amicrowave, a tv and two fluorescent bulbs connecting it to a lead acid battery, and for how long it can provide light to my mountain house, since i have no electricity. i would also like you to recommend me if you know a product for my needs, thank u"

Answer: The power inverters we typically sell convert 12V DC to 120VAC. Your email address indicates that you live in the United Kingdom where power is typically 240VAC. The first unit you refer to has this description: This inverter provides household power on the go! It converts battery power to 120 V AC household power, allowing you to power up multiple loads such office equipment and major household appliances from your vehicle. This unit is ideal for microwave ovens, mini fridges, coffeemakers, laptops, TV sets, video games, CD players, DVD players, cellular phone chargers and much more!

What you missed is that you have to have a vehicle with the engine running in order to power the inverter. If you attach the inverter to a charged 12 volt battery, you will quickly drain the battery of its charge. Remember that watts equals volts times amps. I am not an expert on power inverters. What I do know is that most microwave ovens here in the USA are 1000 watts. This power inverter could power most smaller microwaves if it were connected to an operating vehicle but not to a battery.

A gasoline generator would power your appliances. Another option would be solar panels.

Thanks for your question.
Sincerely, Barbara
