Does the battery charger work with 110-240v?

Asked by Matt April 4, 2021
2
Answers

No it's 110v only, sorry Dewalt makes a multi volt charger but the best way is to use a international voltage converter which can be used to get the voltage and HAZ for your location. I have use one on my Dewalt 20v charger a couple of times when on a cruise ship and they are less than $20 and are very light weight only a few oz. Good luck Alan

How can I give an honest review about using a product when the product comes with not only 1, but 2 DCB207 batteries, WHICH AREN'T COMPATIBLE via the manuals provided. The batteries should have been DCB203's since they would be the closes looking to what was shown on the picture!

This combo was a great deal with the 5ah battery. This is my first XR drill and you can feel the power difference compared to the regular Dewalt Max drills. I think three settings for the led light is kind of a funny feature, but hey maybe one day I’ll need to adjust it! The bag now has a sweet rubber “Made in the USA” logo which is cool.

Do not buy
Bought these because I had accidentally left my spare battery DC9096 and charger behind and would not be back for 3 months to where they were. So I purchased these, big mistake!!! They do not hold a charge for very long. I can fully charge one, set it on the shelf for 2 days go to use it and it’s dead!!! Will not even power my flashlight for an hour!!! Wish I could return but did not keep receipt!!!!

Good strong drill
Mostly happy with this drill. Has plenty of power. Speed is good. Nice weight and size. Comfortable to use. Down side is I didn't know it doesn't have a bit holder. This is an optional accessory. Not so sure it's made in usa. Bag has a big patch on outside that says made in usa then inside says made in asia.

product has the power when I need it, dewalt has produced some of the vest tools I have worked with and I am happy with my decision.
by Jose
2 out of 2 broken in 18 months.
Power was never a problem, but they break easily and DeWALT doesn’t stand behind their tools with their warranty. Go Milwaukee or Makita if possible, but I’d even take a rigid over this.

When my son was young I had a basketball hop installed in our yard. The installer not only cemented the post into the ground he poured cement into the post. I wanted to remove it but couldn't decide which power tool to purchase for the project. I originally decided on a reciprocating saw but decided it wouldn't cut the post as close to the ground as this DeWALT Grinder. This tool did the job perfectly. However, the grinding disc supplied with the tool wasn't quite suitable to the job so I purchased a Rigid Metal Cutting Diamond Blade. This combination was perfect for the project and did exactly what I wanted. It not only cut through the steel but the cement as well. I would highly recommend this tool as well as DeWALT tools as well!
