Is this the type of jumper that you charge inside, by plugging it in, then you are able to jump-start your car with nothing plugged in.

Yes, you can charge it in the house or garage, then you can carry it down the driveway, or down the street... My last one I would charge it up about every 4 weeks to every 6 weeks. I believe I was able to Jump-Start 3 vehicles, but possibly a 4th one, without any issues.... Although this Unit is not really light like one of those Small Hand Held Units, These Units are larger/heavier ones. They can handle Stronger Boosts, and For Longer Periods Of Time..... I'm also getting Battery Tester. Amazon has one for $12.88 Prime 2-Day Shipping. That way I know if it's a Battery Issue, Alternator Issue, or when it's showing a Full Charge, then only starts with someone Jumping the vehicle, then it's probably the Starter....

is there a DC converter from 120v to 240v? my country (singapore) is using 240v wall socket

Yes, I've ordered a small one (200watts) recently off Amazon. The Simran SMF-200 Delux Step Down Voltage Converter...

can you use it to charge a cell phone? Could you use it to run portable dvd players?

Yes and yes. As long as you don't exceed 5 amps. And I believe those two things qualify
