The purpose of this website is to be able to compare prices of different chargers.

So it was only a logical step to add the option to be able to save the calculated information for comparison. This is easily done by entering a "comment" and clicking the "Add to scratch paper" button in the section with the calculated results.

It will show up on top of the calculations in it's own area.

You can calculate changes by just using the "Calculate price" button. No changes will happen to the scratch paper. Once you are satisfied with the result, you can add it as described.

The scratch paper will be deleted automatically after a day. No data will be saved! You will also loose the data if you close your web browser!
