[This review was collected as part of a promotion.] my 18 v charger died and i needed to finish a project, i was able to use this on my tools to finish job without loss time.  you have to press the two latches very firmly to release but it works great

saved me

dewalt.com

This thing has kept an old early 00's DeWalt Sawzall alive and kicking. Love being able to slap in a bigger battery into an older tool  to get things DONE. I've used it in other things to such as my 1/4 impact. I do not seem to have draining issues as much as others but it does happen. I tend to remove my batteries out of habit.

It works

This fits on all of my old 18V XRP tools just fine. I have the hammer drill, impact driver, circular saw, grinder, reciprocating saw, 1/2" impact, and flex light and it works great in all of them. My 90 degree drill won't accept the adapter but I do not think it was ever in an XRP offering and is my only Dewalt cordless tool that is not XRP. The adapter is a little difficult to remove in some tools and is almost impossible to remove if you leave the battery in so it is best to remove the battery first. I just started replacing all of my XRP tools so I only plan on using this while I do that over the next year or so. I am using the DCB205 batteries and the run time seems like about 4 of my old batteries combined, maybe more. It looks odd on the tools and sits at an odd angle but works well so far. None of the larger batteries (6.0ah plus) fit the adapter but the run time is long enough with the DCB205 where having a spare battery would run a tool for a full work day anyway. I noticed a significant improvement in power even over my newer XRP batteries in all of my tools and have not seen any drawbacks besides making the tool overall length longer which makes fitting in tight areas a bit more difficult.

Works well.

[This review was collected as part of a promotion.] I was hesitant to buy this item based on some of the negative comments about it, but I am glad that I did so.  There remains an opportunity to make the insertion and removal of the adapter easier to execute.  However, I was able to do it successfully several times.  Overall a good purchase.

Very reasonable item

[This review was collected as part of a promotion.] I bought this adapter 1 year ago on a whim. In that year i have found that, for the most part, it does its job. I am able to use the newer 20volt batteries on most of my older 18v tools. It can be a beast to remove at first, but over time parts wear down and it comes off as easy as a standard battery. While the 2 batteries that came with it, in the kit i purcased, dont have a super long run time, they will do the job and also work fine on the 20v toolsi also have. I have found that this adapter does hae some limitation. With the battery on, it does not allow the battery door to close on the cordless vacuum. It also does not work well in the cordless angled nail gun, creating a misfire, and jam, every other shot. 

Those 2 issues aside, I believe this to be an excellent addition to my DeWalt tool family and have recommended it to several frieds and co-workers that still are on the 18v system.

Breathes new life into old tools

[This review was collected as part of a promotion.] It is difficult to remove the battery from the adapter. DO NOT LEAVE BATTERY IN THE ADAPTER AS IT WILL DRAIN YOUR NEW 20V BATTERY OVERNIGHT. You would be better off just replacing your 18v batteries.

BATTERY DRAIN

Dewalt

The DCA1820 adapter is draining my 20V batteries overnight and the adapter is VERY difficult to remove from my 18V tools.  What do you propose as a soluton / compensation of these sub-standard adapters that I purchased ?

DCA1820 adapter drains 20V batteries ! :-(

Got this a couple of weeks ago read the instructions and bought batteries. The instructions state it accepts all 20v lithium ion dewalt batteries. This is definitely not true

Not as described

Product does not work on most tools despite advertising it does. Packaging needs to list few tools it will work with. Called Dewalt they confirm will not work with any tools I have. Product is junk. Tools run soon has a light load is on tool, tool cuts out. Have disassemble battery, adapter and tool and reassemble to restart. Worthless!

Do not buy

I have had so much trouble with a battery powered piece of equipment.  I have always been a Dewalt fan but the 18v to 20v adapter is the absolute worst piece of equipment I have ever bought. Probably will be changing colors because of this. 2 years trying to make this work.

Worst ever
