How to measure the output current

[RODALCO]

Measure Amps as follows:

Note, this is at the low voltage side of the charger.

+ (charger) to 10Amp terminal(DMM).
Common terminal(DMM) to load(cellphone battery).
Leave negative (-) as is.

Measure volts

+ to volts terminal.
- to common terminal.

This might be trivial but keep in mind that the insertion of the current measurement instrument (likely to be a DMM) may result in a change in the operation of the load - since a slight but measurable voltage drop can result. As already implied - measure the current and voltage - and I would encourage measuring both at the same time (requring a second DMM or other meter).

My teacher in high school taught and demonstrated how to use a multimeter.
My neighbour also demonstrated how to use a multimeter.

Years ago, universities had professors who actually taught the students, not a puppet lecturer who just reads stuff like today.
Students asked the prof questions that were answered by him, not by guys on a forum.
What has become of education today???

There are numerous publications that do a great job at explaining how to make these measurements. The publications may be in the form of a book, journal or magazine article or on-line source. If you are attending a university I would expect the library to have plenty of these publications. I would encourage you to review several of these. They are likely to offer a complete picture with diagrams and explanations that match the diagrams. You might still have a few questions that can be handled by the forum.
