Review: 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: Despite a number of negative reviews, I found the adapter easy to insert and remove. It is easier if you take the battery out of the adapter before either inserting or removing the adapter from the tool. I have tested the adapter on a number of my old 18V tools and it works perfectly. Don't forget to remove the battery from the adapter when it is not in use (either on or off a tool) as the adapter contains electronic circuitry which will eventually drain the battery. This is easily achieved if you remove the battery from the adapter before removing from the tool. ## Features - Allows for use of 20V MAX* Lithium Ion batteries in most 18V DEWALT tools - Requires use of 20V MAX* DEWALT charger - Do not use with premium DEWALT batteries in DC970 or DC759 tools - This Adapter will not work with 20V/60V FLEXVOLT Batteries - The DCA1820 adapter is compatible with the following batteries only: 1.5 Ah, 2.0 Ah, 3.0 Ah, 4.0 Ah, and 5.0 Ah XR ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B016K1UD0E | | Best Sellers Rank | #94,522 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #326 in Cordless Tool Accessories #907 in Outdoor Power Tool Accessories | | Department | Unisex-Adult | | Item model number | DCA1820 | | Manufacturer | Black & Decker | | Product Dimensions | 14.22 x 8.08 x 17.78 cm; 222.26 g | ## Product Details - **Brand:** DEWALT - **Colour:** 20V - **Compatible devices:** DEWALT 18V tools - **Compatible phone models:** Apple iPhone XR - **Connector type:** Owner - **Included components:** (1) 18V - 20V MAX* Adapter - **Input voltage:** 20 Volts - **Number of Items:** 1 - **Special features:** Waterproof - **Wattage:** 200 watts ## Images ![Battery Adapter 18V to 20V, For Drills, Sanders and More, Charger Not Included (DCA1820) - Image 1](https://m.media-amazon.com/images/I/5171Xa+KTOL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***E on 30 January 2019* I've tried this on all my old dewalt stalk type battery tools.
