12V battery can use 60W iron?
As long as the soldering iron is 12V.If the soldering iron is 220V, no.!
In the past, we have made low-voltage electric iron, 12-24V-36V AC and DC can be universal, power to 20-40W is appropriate!Transformer or DC battery can be used. Transformer power 50-100W!Battery capacity 20-40AH is available!
When the battery voltage is in line with the electric iron voltage, it can be used directly. 220V voltage electric iron, need to use inverter.Battery direct power supply, the operating current is 5A, determined by the work time battery capacity, the calculation method is: 5AX hours /0.8= battery capacity.Inverter power supply, the use of 100W inverter, input 12V, variable 220V can. The overall efficiency is 0.7. usage time is calculated; 60 W X hours /0.7/12V = = battery capacity
