How much current does a cordless tool draw?
Cordless tools powered by 18V lithium-ion batteries can have very high peak current draws of 30-50+ amps but much lower average draw during use. The amperage rating on corded tools indicates the maximum sustained current the tool can handle without overheating, not necessarily the actual current drawn during use.
How much power does a cordless tool use?
According to this exchange, "Typical current draw on 18V cordless tools?", a good 18-20V cordless tool consumes about 500W (~ 30 A) of power under peak load. To compare, corded power tools are rated with typical "8A at 110V", or 1000 W, and since cordless tools are typically half of power of corded ones, these numbers sound about right.
How many amps does a power tool need?
