This blog answers questions about which inverters can be powered by 12V DC accessory outlets cigarette lighter sockets and which require wiring directly to a battery. In addition to that, we answer the most common questions such as fuse selection, wiring instructions, and general Inverter guidelines. Skip to a section: When does a small inverter's power come from a 12V DC outlet and when does that inverter need to be connected to a battery?

The basic decision is based on the maximum power the inverter will supply. That limit is set by the vehicle wiring and the fuse that protects the wiring.

In practice, most fuses can withstand "Hook up power inverter" over current by 10 percent or, in this case 18 Amps. Furthermore, most 12 volt batteries actually deliver So, actual watts that can be delivered can be Hook up power inverter to watts.

Above watts of maximum power output an inverter has to be connected to a battery. This avoids fuses blowing in vehicular electric systems and the subsequent hunt for locating and replacing a blown outlet fuse.

For current loads of watts...

Most battery clip cables are not equipped with a fuse. Battery clips are only used for brief temporary connections to a 12 volt battery. As with all connections to a flooded lead-acid car battery, follow the same safety procedures as you would during jump-start procedures presented below. Connect the Positive battery clip to the battery positive terminal. Then Hook up power inverter the negative battery clip to a metal part of the vehicle frame.

This sequence prevents a spark from igniting any explosive gasses that may be in the immediate battery area.
