We hear this question every single day and the answer is quite simple. To determine how many Amps you are taking out of you batteries per hour, as a general rule of thumb, take the AC Amps (amps of the devices plugged into the inverter) and multiply by 10. For example, 5A of fluorescent lights = 50 DC Amps. You are taking 50A out of your batteries per hour if those lights are turned on for the full hour.

Sidebar: If you are running a 4A fridge for example, using the above formula you will not be drawing 40A DC an hour. The fridge will cycle on and off many times during the course of an hour so you’ll be drawing LESS than the 40A DC.

I live in bright, sunny, and stormy Florida. Last year, was even a bit too stormy for my taste. We had two major hurricanes in our area that resulted in 5 to 6 day power outages and required us to purchase new refrigerated food after the first one. We became so feed up with the loss of electric power and the constant drone at night of our neighbor’s generators that I arrived in desperation at a new idea after the first major hurricane.

A little aside, both my wife and me own hybrid electric cars, both of the cars are equipped with large battery packs (202 and 274 volts DC) in the trunks for the electric drive motor and a small auto 12-V DC battery in the trunk for all the accessories. Before the next storm that hit I was ready, I ordered a 1250 Watt AIMS inverter from Inverters-R-Us, jumper cables, and a new deep cycle battery.

The next storm knocked out the power again but this time I was ready. After the storm cleared the area, I hauled my fully charged deep cycle battery out to my car parked in our circle drive. Opening the trunk I placed the deep cycle in the trunk, connected the jumpers to the small 12-V battery in the car and then to the deep cycle battery in parallel, connected the inverter leads to the deep cycle battery and ran an extension cord from the inverter in through the side window to the kitchen. The beauty of this situation is my hybrid car has an inverter that is used to charge the 12-Volt battery from the large battery pack in my car as long as I leave the key in the ON position with all my accessories off. I can close the trunk, lock all the doors and walk away, the gas engine turns on and off as needed to keep the batteries fully charged and the refrigerator and other appliances can always be on. The gas engine barely runs since it just needs to top off the 274 Volt battery (10-20% of the time) and my wife and I do not have to deal with the fumes and noise of a generator. We are extremely happy with this situation and are considering buying another inverter for her hybrid.

Thanks for helping us get through another storm.

The Rally 150 Watt power inverter (part number 7414) is a pretty slick little unit. It features 2 AC receptacles, 1 DC port and 1 USB port. The AC receptacle on the right side of the unit is “sideways”, which makes it handy for example when using something that has a “wide” or “built in” adapter such as a digital camera battery charger.

Another nice little feature is the included iPod Quick Charge Interface Adaptor which you can see in the owners manual. All in all, this little inverter has all the bells and whistles you would ever need in an inverter this size, capable of running pretty much any laptop out there today.

If you have any questions about the Rally 150 watt power inverter, please let us know and we’ll be glad to answer them for you. I use ths inverter everyday in my daily driver and I have a choice of many if you can imagine.
