I wasted a couple bucks on a separate cigarette lighter plug when I ordered because the product information says nothing about coming with the cigarette lighter plug.
Oh - There is also a sticker on the cigarette lighter cable warning not to draw more than 150 watts when using it plugged into a lighter socket (use the alligator clips or your own custom wires to connect straight to the battery for full power)
Upgraded from 1 to 3 stars: I have since "hardwired" the inverter to my vehicle battery with an Anderson Power Pole 50amp connector in between. With this configuration I have been able to get a full 400 watts reliably from it. I have been running this setup for about 2 years now. I use it about an hour continuous once a month.
Updated: have been running for about 4 years now. It works fairly well. As mentioned above I had to "hardwire" it to get the rated capacity. Even using the included alligator clips connected to clean battery terminals did not give me a good enough connection to supply the full rating. I often run a 300 W halogen lamp as well as things liek a laptop and mobile battery chargers.
The lighter cable option allows taking this unit in a different vehicle. My unit came with both lighter plug and jumper cable type power connectors. The lighter plug has a 15A fuse in the tip, limiting output to a continuous 165W (hence the 150W mentioned in the manual). Higher power levels will require direct connection to the battery terminals, or the fuse will blow.
The lighter plug, as noted in other reviews has trouble staying electrically connected in my Cadillac Seville lighter socket, but doesn't fall out. The rear passenger lighter sockets have the same mechanical connection issue.
[The following comments were made from a unit sent back for repair. Addendum comments made against a new unit are at the bottom of this review, and new scope image replaces the old one in customer images.]
With the unit connected to a car battery with the engine running for high power checking, a Hoover 110V hand vacuum runs just fine. I grabbed a 500W halogen contractors light to see what happens on overload. The lamp starts to light and about 200mS later (~1/5 sec) the units starts shrieking and turns off output. [This behavior changed in the new unit (below) which now powers the 500W lamp for a minute] This unit does not recover from this condition automatically. The front panel switch must be turned off, then back on for the unit to recover. This also implies that any motor load with high startup currents has to be substantially started in 200mS or the overload condition will trip on this inverter.Read more ›
