Delivered without instructions -- where can a 'user's manual' be found?

Hi, there is a PDF Instructions on the product page -- Product information -- Technical Specification -- User Manual pdf https://images-na.ssl-images-amazon.com/images/I/C1X8DiomGTS.pdf Hope it could help you.

Is the usb output fixed or is it adjustable?

It's not fixed. I had it as high as 13.3 volts in my application of the USB connector. You need to set output to 5v before using any standard usb device.

In the instructions it says to use a diode if using for charging, where does the diode go?

There are two good answers here; when charging a battery with this converter, a series diode should be placed between this device's output and the battery to prevent the battery from attempting to backcharge this device if this device's output drops below battery voltage. In addition... if this device is used as a charge controller for a phototaic (solar) panel, a series diode should also be placed between the panel and this device to ensure that this device will never attempt to backcharge the panel. I suggest the use of a fairly significant Schottky diode for either application.

Constant output voltage with changing input voltage? If I have solar panels as an input with a chaning voltage (+-. 5V) will this affect the output?

Check the limit of input shown in the instruction manual. This unit will regulate voltage or amperage, but not both at the same time.
