## Questions & Answers

**Q: My model train layout has a bunch of mini-led lights.  they are expecting 12v dc.  will this work for this application?**
A: I would expect the mini-LEDs have a low current draw, so this will probably work -> 12V DC 2Amp output. The screw terminal adapter may make it easy to wire in.

**Q: How long is the cable?**
A: As the Amazon ad states it is 3 feet long.

**Q: Does female adapter have pin inside or not?**
A: Yes, the female adapter has a pin inside the barrel.

**Q: Do they get very hot say burn to a fast touch?**
A: these operate at the same temperature as your Modem or switch power supply for your computer. just warm not hot. Remember, do not overload them 2 AMP MAX.
