Turn a Dewalt 20V battery into a portable power hub with the TANHEYIN 300W Power Inverter. This compact converter steps DC 20V up to AC 110–120V, delivering power where outlets are scarce—perfect for phones, tablets, laptops, radios, fans, and small tools during outdoor adventures, road trips, or a sudden outage.

Designed for real‑world use, this inverter is compatible with the Dewalt 20V/18V DCB series batteries. Slide the adapter into the battery slot and lock it in place to power your devices on demand (battery not included).

Power, ports, and performance at a glance

This portable inverter supports two AC outlets with a combined 300W max, letting you run light-powered equipment alongside your devices. A PD 65W Type-C port enables fast charging for compatible laptops and phones, while two USB-A ports cover everyday charging needs. In addition, a dedicated Type-C port (PD 20W) adds flexibility when you want to keep data devices powered without swapping cables.

• Two AC outlets up to 300W total
• PD 65W Type-C fast charging
• 1 USB-C 20W PD port
• 2 USB-A ports for everyday devices

Practical uses

• Charge smartphones and tablets during camping or road trips
• Power a compact laptop for work on the go
• Run a portable fan or small radio during emergencies or outdoor events

Smart safety and battery care

Smart protection guards against low voltage, over-voltage, overload, short-circuit, and overheating. If input DC drops below 15.5V, the AC outlets cut off automatically while other ports stay active. For longevity, consider removing the battery when not in use. When input falls below 15V, all power functions stop.

Compact, quiet design for everyday carry

With dimensions around 4.8 x 3 x 1.8 inches, this lightweight unit slips into bags or backpacks. A built-in cooling fan starts when the inverter is on, providing steady heat dissipation without excessive noise. Note: high-power devices over 300W are not recommended. This inverter offers flexible, battery-powered power where traditional outlets aren’t available, making it a practical companion for camping, travel, or home backup.

Potential benefits vary with device and conditions; this unit is designed to support a range of small to mid‑sized power needs with Dewalt batteries, not a guaranteed result for every setup.
