Cigarette lighter plug power?

Postby SAILOR » Mon Jan 17, 2011 10:40 am



Was wondering if I can plug a 300 watt inverter into the cigarette lighter plug without overloading the electical system on my 1984 Aspencade? I want to use the inverter to charge my laptop while riding.

The total output of the GL1200 stator is 300 watts. Considering that those 300 watts have to charge the battery, power the headlight, taillights, engine and accessories, leaving you with about 90-100 watts to spare, running a 300 watt inverter is probably not going to work well. You'll find that you will be powering the inverter from your bike's battery - the stator will not be able to keep up, and you will end up actually draining your battery while riding, leaving you stranded.

That said, the inverter doesn't always draw 300 watts - only when it is under maximum load. Most laptop power supplies draw between 100 and 150 watts (check yours to be sure). With loss in conversion within the inverter, a 150 watt laptop power supply would likely be drawing at least 170 watts at the supply side of the inverter - still far more than is available.

Your only solution would be to use a Poorboy alternator conversion, which supplies upward of 500 watts, and could easily power your inverter/laptop.

That is what I am goning to do to my 84 gl1200. I found that using all my light will drain my batt quick riding through town. I found that out the hard way a couple of times! I wouldn't recomend powering anything other than cell phones, ipods or gps's.
How many times do I have to tell ya,,, The right tool for the right job!

My '86 GL1200 Aspy doesn't have a power recepticle (yet) but it does have a knock out for one. Can I put one in and have it power a GPS system? Maybe an MP3 player (which I do NOT have yet)? My bike still has the stator setup, not a poorboy (again,,,YET!).

There is more than enough reserve to power those. I have a satellite radio, GPS, heated gloves and two 35-watt driving lights on my 1100. I had to switch all the rest of the lights to LEDs to do it, but I have enough power with a bit of reserve to run it all.
