## Description

Listed are these genuine DEWALT DCA1820 Adapters that allow you to now use your older NANO or XRP tools with the latest XR Slide-on Lithium ion Batteries. You simply plug the DEWALT DCA1820 adapter into the base of say your DCD950 / DCD970 Hammer Drill or DCD825 / DC827 Impact Driver and then slide in an XR Lithium ion Battery and away you go. Works perfectly with most NANO or XRP tools as listed below. You can use 1.5 Ah, 2.0 Ah, 3.0 Ah, 4.0 Ah and 5.0 Ah XR Slide-on 18V Batteries with this adapter. FOR: DCD950, DCD970 Drill, Driver Hammer Drills DCD760, DCD775 Drills & Hammer Drills DC212, DC213 SDS Rotary Hammer Drills DC825, DCF826, DC827 Impact Drivers DC820, DC822, DC823 Impact Wrenches DW059 1/2" Impact Wrench DC330 Jigsaw DC385 Reciprocating Saw DC411 Angle Grinder DC490, DC495 Shears DC515 Wet & Dry Vacuum Cleaner DC550 Plaster Cutout Tool DW074 Laser Level * DW077 Laser Level DW079 Laser Level * DW908 Swivel-head Xenon Torch ** DW919 Flexible Snake-light Xenon Torch ** DC527 Fluorescent Hanging Light ** DW960 Right-angled Drill * Door won't shut on these model laser levels with the adapter/battery in place. Works, but not waterproof. ** Some pulsing is evident when used with these DEWALT torches / lights. This adapter will not work with DEWALT's latest 54V (60V) 6.0 Ah or 9.0 Ah FLEXVOLT Slide-on batteries. Contents: 1 x DEWALT DCA1820 18V XRP / NANO to XR Slide-on Adapter.

Review: Makes my old tools work again - I've tried this on all my old dewalt stalk type battery tools. All tools work again with this adaptor now. The price is a bit excessive but if these tools keep working with this adaptor then it's well worth it. The adaptor came in proper plastic retail packaging with instructions so I have no doubt this is a genuine dewalt product
Review: Give me more Power! - Works great with my old XRP Nicad drill. Feels like got more power too with Lithium Batts but could just be imagination playing tricks again. But definitely benefiting from longer run time especially with 5.0AH battery. No probs inserting into drill or disengaging. What I would say probably an obvious downside is size increase of tool with adapter fitted.

## Features

- Requires use of DEWALT 20V MAX charger

### ⭐⭐⭐⭐⭐ Worth the money
*by J***Y on 9 March 2019*

I had previously bought cheaper versions which come loose and don’t allow full discharge of the battery, this one yes more expensive but worth it as it works perfectly
