As I don't have at the moment to buy a power pack for my speedotron 1604 brown line I have been looking online for an inverter and came across some inverters that are 750watts and one that is 1000watts made by Peak and Duralast. These come with connectors that plug into your car battery (they look like jumper cables). I did see that it does say modified sine wave. I know it seems real tacky to use this but for $80-$100 I can use for the moment.
As it is not "portable" because I would not be able to take with me unless I unplug the battery from the car. But wanted to see if any one has used something similar or has known someone who has used one or simply knows if it will work or not.
Thank you for your help.
