About Product Overview

The DCA1820 solves a problem a lot of DeWalt owners run into: a drawer full of older 18V tools and a charger full of newer 20V Max batteries that don't fit. This adapter bridges that gap, letting you run 18V tools off 20V Max packs instead of retiring perfectly good equipment or hunting down discontinued batteries.

It's built as a simple pass-through with a charging indicator light, so you know when power is flowing. Lithium-Ion compatible, it's a small piece of gear that extends the working life of an existing tool collection rather than forcing a full battery-system upgrade. Good fit for tradespeople, remodelers, or anyone with a mixed fleet of older and newer DeWalt tools who wants to standardize on one battery platform without buying new tools outright.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
