It's not amperes it's Ah. 1 watt = 1 volt-ampere. The watt (symbol: W) is a unit of power. This tool converts watts to volt-ampere (w to va) and vice versa. 1 watts to volt ampere = 1 volt ampere. The volt is named after the Italian physicist Alessandro Volta. Volt-ampere and watt have different meaning. This calculator is designed to help you find a deep cycle battery when a continuous load is applied, not for cranking or starting purposes. 5 watts to volt ampere = 5 volt ampere. Product Title 12 Volt 7 Amp Hour Alarm Battery - 10 Pack. This inverter is packed with power but still small enough to fit in small spaces. Type in your own numbers in the form to convert the units! Current consumption depends on the load. The AIMS POWER 5000-Watt modified sine wave power inverter 12-Volt DC. Use this page to learn how to convert between watts and volt ampere. ›› Quick conversion chart of watts to volt ampere. It's written on the battery itself. One volt is defined as the "difference in electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points." Here at Walmart.com, we are committed to protecting your privacy. This inverter is capable of providing up to 41.6 Volts are the base unit used to measure Voltage. Do you need a 12 volt battery for your application but don't know what size? A volt-ampere (VA) is a derived SI unit used for the apparent power in an electrical circuit, equal to the product of root-mean-square (RMS) voltage and RMS current. The unit, defined as one joule per second, measures the rate of energy conversion or transfer. For example: A typical specification of battery is 12V 7Ah. The user must fill one of the two fields and the conversion will become automatically. Volt-amperes are used only in the context of alternating current circuits.
