The question now is, are cordless impact wrenches worth it?As with any tool, there are pros and cons in owning a cordless impact wrench. One glaring benefit of a cordless impact wrench is its portability. You can use a cordless impact wrench anywhere, anytime without the hassle of either lugging an air compressor or scouring for an electrical outlet. A cordless wrench is handy when doing quick jobs such as changing one tire or for removing a couple of rusty lug nuts. A cordless impact wrench is also handy for weekend DIYer who in all probability use the tool only on occasions.
What are the cons? Power for power, a cordless impact wrench delivers about less than half of its corded counterpart. A traditional ½ inch air impact wrench can deliver about 700 to 800 ft.lb of torque while a ½ inch cordless impact wrench can only deliver 250 to 325 ft. lb of torque. A cordless wrench is heavier than a traditional one because included in its gross weight is the weight of the battery pack. A cordless impact wrench is also more expensive than a traditional one. A cordless one is pegged at $300 to $500 while a corded one is from $175 to $250.
