Bidirectional Power Converter For DeWalt 18V 20V Battery With USB Fast Charge
Transform your spare DeWalt 18V and 20V lithium tool batteries into dependable portable power sources with this bidirectional converter. Built for contractors, hobbyists, and emergency preppers, the unit bridges the gap between discarded tool cells and everyday electronics. A real-time digital display continuously monitors voltage across a 2.4V to 30V range, helping you track cell health without guesswork. Integrated USB and Type-C outlets deliver fast charging directly to phones, cameras, and routers, while flexible port options let you run power tools, RC chassis, cooling fans, or small appliances without draining your remaining juice.
Benefits & Tips
- Use the dual output configuration to charge a smartphone via USB while simultaneously powering a DC work light, keeping both mobile devices and essential gear running without interruption.
- Feed an external 9–30V adapter into the input terminal to operate the converter completely independently, creating a reliable offline power station for campgrounds or grid outages.
- Check the voltage display after each session; if readings dip toward 2.4V, disconnect the load immediately and recharge the original power tool battery to preserve cell lifespan.

Warnings & Reminders
Maximum safe operating voltage is 30V; always verify correct polarity when connecting wires to prevent short circuits. Keep the adapter away from moisture, dust, and flammable materials. Maintain clear airflow around the unit and stop use immediately if it becomes excessively hot. USB and Type-C ports must never be used as power inputs. This device functions purely as a power converter, not a battery charger. Disconnect all loads and store the adapter separately from batteries during extended idle periods to prevent deep discharge damage.
