I’m old school and could do the math myself to convert the current, but this app is faster and accurate leaving me the time to design panel racks and other mechanical issues. Could’ve used this years ago. Overall a very useful app for the novice and the pro! -- Davijdd, 2022-08-13 ### *---- "Adware" Just a big ad -- Jack m m I rschvv B chh G hm, 2022-02-09 ### *---- "Too many ads!" I didn’t realize this app was going to be a non-stop series of adds! -- Arrdvark12000, 2021-07-08 ### ****- "Works well" Works well, would be nice to have a general chart of appliances wattages usage, but it is short and functional -- Rperkd100, 2021-02-17 ### ***** "Quick & Handy" I used this app while building a solar generation system, it was very useful when calculating consumption of appliances and other devices. -- Bill Jensen, 2021-01-10 ### ***** "Easy and uncomplicated, simply the best !" Watts , Amps , Volts any you would like to do, this App is just what you need ! -- Danyguz, 2020-12-26 ### ***** "R J" Comes in super handy! -- Silvertop007, 2020-09-17 ### ****- "Good look" My first week and it’s good so far ,,,,, Should have more to calculate tho... it make current & voltage assessments easier -- dixonreino, 2020-06-04 ### ***** "For someone who has lost his memory,this is great." 😁 -- all all up, 2020-03-24 ### ****- "Nice" Nice to have -- curiel00, 2020-02-21 [View all Watts Amps Volts Calculator reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Watts Amps Volts Calculator Discovered Keywords -
