Voltage Calculator Portable

Developed as the portable twin of Voltage Calculator, this tiny Java-based software utility has a simple purpose in mind, namely to enable you to easily calculate voltage values based on wattage and resistance. Actually, it does not come packed with any other options, making it accessible to all types of PC users, whether they are experienced with such tools or no.

No installation necessary

Since this is a Java-based program, there is no need to install Voltage Calculator, as long as you have Java on your computer. You can just move the app directory to any part of the hard disk and just click the executable file to launch the tool.
There is also the possibility to save Voltage Calculator to a pen drive or other form or removable storage unit, in order to run it on any PC with minimum effort and no previous installers.
An important aspect worth keeping in mind is that it does not create new entries in the Windows registry or Start menu, so it does not leave any traces behind once it is removed.

Simple interface and options

The UI is represented by a small frame with a plain and simple layout, where you can type or pate the wattage and resistance, as well as click a button to find out the voltage in an instant; it is shown on the bottom part of the screen.
Although Voltage Calculator does not integrate options for exporting data to file, printing it or copying it to the Clipboard, the latter action can be achieved by selecting the characters and using the global keyboard shortcut. There are no other noteworthy options available.

Evaluation and conclusion

As expected, Voltage Calculator's impact on system performance is insignificant. It uses low CPU and RAM, has a good response time to commands and instantly calculates voltage values. It worked flawlessly in our tests. Thanks to its overall simplicity, the app can be handled by anyone with great ease.
