  • 100W Power Inverter

    Hi, I'm want to add a plug in my car, something small to recharge laptop, cell phone etc. I don't want to use the a cigarette lighter type but would like to hardwire it to my battery. What do I need to have this done?

    Thank you

    its better not to change anything directly in the circuit of the battery

      You need wire that is sufficient to carry the electrical load, a fuse of appropriate size to protect the wire and a means of attaching the wire to the battery terminals.
      Have you looked in the FAQ yet?
      How about the Wiki?

      Under normal circumstances, a signature would go here.

        In the trunk I already have a fused Distro block that has 4ga coming from the battery and four 8ga outputs. What size fuse do you recommend I use?

        Thank You

          Whatever suits the cable you use to power the inverter.
          100W @ 12V means about 10A, so hence probably a minimum of a 15A fuse (if not 20A) to allow for inefficiency, surges etc.

          Remember - you are protecting the cable - not the inverter.
