How to Make a Portable Outlet With a Battery

Having a source of electrical power for emergency usage is a wise precaution, especially if you live in an area that may be prone to natural disasters. Even the capability to run a few small electrical appliances can make a big difference in your comfort and ability to communicate. With some basic gear, you can put together a system to convert DC (battery) power to AC (outlet) power quite simply.

Step 1

Remove 1/2 inch of insulation from one end of the black and red cables with wire strippers.

Step 2

Slide a ring terminal over the bare ends of each wire, and fasten into position by sliding the crimp tool over the terminal and crimping them in place.

Step 3

Remove 1/2 inch of insulation from the other ends of the cables.

Step 4

Place a battery terminal over the bare ends of the wire and fasten them into position. Different types of battery terminals will use different fastening methods—some require you to tighten a set screw, others clamp on with a nut and bolt. Use the appropriate tools for the type of battery terminal you have.

Step 5

Loosen the screw terminals on your inverter. Most inverters use a simple wing nut you can loosen and remove with your fingers. Slide the positive cable's (red) ring terminal over the positive (+) post, replace the screw and tighten; then repeat with the negative (black) cable and negative (-) post.

Step 6

Slide the battery terminal on the red cable onto the positive post of your battery and tighten it with a small adjustable wrench. Slide the battery terminal on the black cable onto the negative post of your battery and tighten.

Step 7

Turn on you power inverter and plug in any electrical gear.
