I am thinking of getting a 12 volt inverter of some sort of wattage for the wagon one day. I`ve done the usual Google search here and there, just wondering what other people have / are using. At the moment I have only a couple of self inflating air mattresses of around 75w, a camera battery to charge. I have seen a Repco 600w pure sine wave inverters for around $249 on spesh, Jaycar 600w pure sine wave with 20A solar regulator built in to it for around $499. I have looked at 1000w inverters and don`t mind having extra power for Justin Case. I`m open minded on other brands and know there are cheapies and expensive units out there. I`m just looking for a reliable unit and eventually hook up solar power one day, hence looking at the Jaycar inverter with the built in regulator.
