Ryobi 18V to Porter Cable 18V Battery Adapter
Ryobi 18V to Porter Cable 18V Battery Adapter
Use your Ryobi 18V ONE+ batteries on Porter Cable 18V Ni-Cd cordless tools, without buying into a second battery platform. Voltage is not the obstacle here — both sides are 18V. The socket is, and that is what this solves. Built with a durable injection-molded ABS housing and pure copper contacts for steady current delivery. Your existing batteries do more work, and there is no second ecosystem to buy into.

Why choose this adapter
- Your Ryobi 18V ONE+ battery and Porter Cable 18V Ni-Cd tools run at the same voltage, so the adapter changes the fitting rather than converting anything.
- Injection-moulded ABS, not 3D printed — no layer lines to split under load.
- Solid copper terminals, so less of the current is lost as heat.
- 5 mm² internal wiring, rated for 40A continuous with 80A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.
- Covered by a 12-month warranty from the day it arrives.
Ryobi 18V ONE+ and Porter Cable 18V Ni-Cd compatibility
It works in one direction only: Ryobi batteries powering Porter Cable tools. For the opposite pairing, see adapters that run on Porter Cable 18V Ni-Cd batteries.
Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Ryobi 18V ONE+ platform and that your tool takes Porter Cable 18V Ni-Cd batteries.
Important charging and safety information
This adapter is for powering cordless tools and nothing else. It cannot charge Ryobi or Porter Cable batteries and must never be connected to a charger of any kind. Always take the battery out of the adapter before charging, and charge it on the original charger made for your Ryobi 18V ONE+ battery.
