How to choose the right voltage for a cordless jigsaw?

	When it comes to cordless power tools, voltage is the main factor that determines power. Cordless jigsaws are available with voltages from 12 to 36 V. Higher voltage jigsaws provide more power, allowing them to cut thicker, denser materials more efficiently than lower voltage jigsaws.
Statement
	For light and infrequent cutting of materials such as softwood or plastic, a cordless jigsaw with a lower voltage of 12 V will suffice.
	On the other hand, if you will be actively working with denser materials such as hardwood or metal, you will need a tool with at least 18 volts. Although cordless jigsaws are generally considered less powerful than their corded counterparts, high voltage cordless saws can work just as efficiently as corded tools.
Duration of use
	Generally, higher voltage jigsaw batteries also have a higher capacity. This means they can last longer between charges. If you plan to use the jigsaw intensively for a long time, a machine with a higher voltage will be able to provide the necessary cutting power for longer periods of time.
The weight
	As cordless jigsaws become more powerful, they also become heavier due to larger batteries. This should be kept in mind if you plan to use the tool regularly. However, this is not as much of an issue as it used to be, as advances in battery technology mean that power tool batteries are lighter than ever before.
Price
	Because they are more powerful, it's also important to note that higher voltage jigsaw batteries tend to be slightly heavier and less affordable. If you rarely need 18V jigsaw power, there is no need to spend a lot of money on a high voltage model.
	On the other hand, if you're planning on using your tool extensively for cutting particularly hard materials, then it's worth spending the extra money to make sure your jigsaw delivers the power you need.
Other power tools
	If you already have, for example, a cordless circular saw, then you should buy a jigsaw from the same manufacturer with the same voltage. You may find that you can use the same batteries (and charger) with both tools. This can make your jigsaw more affordable as you may not have to buy a battery with the tool. On the other hand, you may have an extra battery to use with any tool, which will come in handy during extensive work.
What voltage to choose?
	Most cordless jigsaws are 18V and are capable of most cutting tasks. However, if you regularly use your saw for heavy cutting jobs, a heavier duty tool with a higher voltage will give you the more power and longer run time you need.
