⚡ At a Glance
- • Power Conversion: Converts DeWalt 20V (DCB200/DCB201/DCB203) and Milwaukee M18 (48-11-1815/1820) batteries to run DeWalt 18V tools without wiring changes.
- • Best for: Tradespeople and DIYers who juggle mixed-brand batteries and need quick cross-compatibility on site.
- • Not ideal for: Anyone needing to charge tool batteries, or users who require integrated hands-free tool controls.
Cross-brand conversion supports common DeWalt and Milwaukee battery packs. Dual USB ports add practical on-site device charging while built-in protections improve safety.
Mixed-workshop compatibility - with cross-brand power conversion
Adapter accepts DeWalt 20V Li-ion packs and Milwaukee M18 Li-ion packs, matching their output to DeWalt 18V tool contacts without any wiring modifications. Compatibility notes cite specific pack models and legacy NiCad replacements.
Run 18V drills, grinders and saws from spare 20V or M18 packs, reducing downtime when battery types differ and cutting the need to carry multiple adapter types.
On-site device charging - thanks to dual-port USB 5V/2.1A
Upgraded DCA1820 design includes two USB outlets rated at 5V/2.1A, drawing power from the attached battery rather than charging the battery itself. The spec supports repeated device top-ups from a single battery cycle.
Charge phones, lights and other small kit between jobs, with a full smartphone recharge possible two to three times per battery cycle, keeping teams connected on site.
Safer workshop use - with fireproof housing and electrical protection
Fireproof ABS housing combines with overload and short-circuit protection, and clear instructions advise removing batteries idle for more than seven days. Product copy expressly warns against using the adapter to charge batteries.
Reduced fire risk and explicit usage guidance suit busy job sites, while overload protection guards tools and devices during routine use.
