DC Converter Voltage 12V to 5V 3A 15W Buck Converter Module, DC Reduced Voltage Regulator Car Power Adapter with Output Power Adapter

Q: Can this coverter's input wires be safely connected directly to a car battery?

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?

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

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?

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.
