Full-timers and those with more robust system will likely want to install 12v power outlets in their van. Doing this means one can move electrical items around and plug them in where you want them.

The most common 12v outlet is the cigarette lighter outlet. The version shown here has USB outlets built in, also.

Pro:

• universal

Con:

• large
• typically limited to 10A or so
• notoriously unreliable, although Blue Sea makes a locking marine version that is robust

The most common non-ciggy connector is the Anderson Powerpole.

Pro:

• when assembled correctly, polarity is assured even when you aren't looking
• slide together in pairs in different arrangments and directions
• robust, especially for frequent connects/disconnects
• power distribution blocks can be very neat and small

Con:

• ciggy adapter needs to be cut off
• more $$$
• need to be assembled¹⁾
• the different possible arrangements means you'll need to pick an arrangement and stick to it
• a special crimper is recommended
