Surplus Computers has the Emergency Cigarette Lighter Car Battery Charger for $15 with free shipping. Utilizes the cars' 12V accessory outlets to charge; no jumper cables required.
From description: "If your engine is just turning slowly, then all you need is a quick 3-5 minutes charging time, but if everything is completely dead then it will require about 25-30 minutes of charging"
When you leave your lights on, your battery is completely dead, period. Good luck asking your friend to leave his car running for 25-30 minutes.
Or you could advance your problem solving skills by learning how to use jumper cables and be done in 1 minute.
To recap STEP 1: Connect one end of the Positive(+) cable to the Positive(+) post of the dead battery.
STEP 2: Connect the other end of the Positive(+) cable to the Positive(+) post of the good battery.
STEP 3: Connect one end of the Negative(-) cable to the Negative(-) post of the good battery.
STEP 4: Connect the other end of the Negative(-) cable to a good solid SHINY, NON PAINTED metal part of the engine on the dead car. Usually a giant shiny nut on the engine block will do. A painted, dirty, or oily nut will not work. You usually want to avoid placing the Negative(-) cable directly on the dead battery to minimize the chance for explosions. You should only use the ground post on the dead battery as a last resort. On this step you'll get a normal spark as you connect the ground and complete the circuit.
One thing that will REALLY help is spraying starting spray on the air intake. Of course, starting fluid with a dead battery is useless but the slightest spark with a weak battery will turn the car over.

Another case of Ben hawking crap product.... spend the $15 on decent jumper cables.
this is total crap but might work good as geek doughnut plugs.

^ If you flick your bic a few times around the battery you can usually burn off the explosive gasses so you don't have to worry about explosions.

True story bro, I once started a Kenworth from my Toyota Tundra with one of these.
