Customer Reviews

DeWalt Vehicle Charger -- Must have for punch outs
This product is great for anyone that is always on the go and does not have access to an electrical outlet to plug in a battery charger. I use it everyday while performing a/c punchouts. I have owned it for 3 years and the only thing that I have found to be concerned about is overheating the charger and batteries on hot summer days.

DON'T USE A MODIFIED SINE WAVE INVERTER INSTEAD
One of the reviews here suggests using a modified sine wave inverter such as the Xantrex sold here at Amazon. If you read the inverter owner's manual or do a quick Internet search you will see that use of an AC Dewalt (and some other cordless tool chargers) together with a modified sine wave inverter will dramatically shorten the life of your charger. Don't do it.

As for this product, it works as advertised. Why only 3 stars? 2 reasons: A) At the current price this item really is overpriced for what you get; B)The (50% less costly) AC charger offers "Tune Up" mode, which extends battery life. But if you have no access to AC power this is the way to go.

dewalt 12v vehicle charger
I used the 18v tools to build an entire remote cabin where there was no regular electricity. The vehicle charger works great connected to a 12 volt solar power system.
