How to choose DC to AC power supply inverters

How to choose DC to AC power supply inverters

Automobiles
Most electrical and electronic devices run off 115 volts AC (110 to 120 volts, or 220 to 240 volts in some countries). Adapters are available to charge cell phones from a car battery's 12 volts DC. However these need to be purchased separately and will often need to be changed for each new phone. Using an inverter (often misspelled as "invertor") means that devices can be used in the car without any special converters. Depending on the power rating and type, inverters can cost as little as $25 for a 100 watt model (modified sine wave) and can reach hundreds of dollars for more powerful models. Pure sine wave models (see explanation below) start at about $100 for 100 watts. Popular brands include Xantrex (Prosine, Trace, Freedom), Coleman, Vector and AIMS. Cigarette Lighter Versu...

The problem could be as simple as a dead battery or as complex as a bad fuel pump or neutral safety switch. One tool that is absolutely essential to diagnose the issue is a multimeter. An inexpensive multimeter can be purchased at Radioshack for under $20. No Crank, No Start In this scenario, either the starter is clicking or nothing is happening. Try turning the lights on. If they are dim, then this is an indicator that the battery is dead and needs a jump or recharge. If the lights aren't dim, then there is another issue. Use a multimeter to check the voltage on the battery. To do this set the multimeter on the Volts setti...
