120 volt ac to 18volt dc 15amp 2

[bigfoote]

I need to purchase or build a converter to go from 120volt ac to 18volt dc about 15amps. This is to run my Dewalt circular saw. The saw rapidly drains the batteries. I mostly use a Tennyru steel cutting blade in it. There was a previous post on this, but I can't seem to find it.
Thank you for any help or suggetions.

Suggestion: It may be better and safer to buy one on market with an industry standard label, e.g. UL, etc.

and type Converters: AC-DC under Product or Service, which will return 116 companies to approach to.

What you looking has two common names. "Rectifier" or "Power Supply". I also think you purchase one. The Amperage that you are talking about makes it hard to build.

Try searching for Power Supply first.

It might be more cost effective to buy a saw that will run directly on the 120 VAC.

jbartos,
Are you saying that it is unsafe to use 120 volt AC powered tools for construction work????

The cost of the 120 Vac to 18 VDC/15 amps converter is going to be higher than buying a 115 VAC saw with the same capabilities and size.

Also, there is the need to check the starting current of your unit that may force you to buy a much higher current capability converter
