## Questions & Answers

**Q: Can this coverter's input wires be safely connected directly to a car battery?**
A: Yes, they can be direct connected to batteries.  The poster saying you can't because a car battery has too many amps is wrong devices only draw the amps they need.  Hook a 1 and 10 amp device to the battery at the same time, each device will draw 1 and 10 amps respectively.  Also agree with them, if you do it protect it with a fuse otherwise if the device fails/shorts all the power of the battery will go through the device and it will likely catch fire.  If protected by a fuse, the fuse will blow.

**Q: What size fuse do I need for that?**
A: You could look in your vehicles owners manual and determine what size fuse runs whatever circuit you're tying in to... I tied it to the cigarette lighter so look in owners manual for fuse size of cigarette lighter circuit.

**Q: Does this get hot? I was thinking about using double sided tape to stick it to a plastic car interior part**
A: No, it won't. Please kindly note that the power of the device must be less than 15W when using a voltage converter.

**Q: Does the converter draw any power if no usb device is plugged into it?**
A: It doesn’t draw any until something is plugged into it. Once pos and neg are hooked up it is always hot. It’s put together nicely too, I’m happy with it.
