What if you could use the same battery across every major power tool brand? For serious DIY enthusiasts, this kind of flexibility could dramatically transform the tool buying process by allowing consumers to pick the best power tool option across any brand instead of just the one whose battery is compatible with their pre-existing equipment.
The CEENR PDNation is a third-party 21700 battery that, on paper, may finally be the universal battery system power tool consumes have been waiting on.
What is the CEENR PDnation?
While some manufacturer batteries, including most notably DeWalt offer some interoperability with other power tools, often via a third-party adaptor, the flexibility of CEENR’s PDNation is in a class of its own.
As of right now, the “universal” battery can ship with a series of adaptors that allow it to connect DeWalt, Craftsman, Bosch, Porter Cable, Black & Decker, Makita, Milwaukee, Einhell, and Worx power tools. Though technically not “universal,” that list does represent a vast swath of the existing power tool market, with the only significant omission being Ryobi, as several Redditors have noted.

The PDNation can also double as a portable power bank for charging USB devices like phones and tablets thanks to an integrated 45W USB-C PD3.0 Bi-directional charging port.
Based on recent thorough testing by the reputable Youtuber Torque Test Channel, the PDNation appears to deliver on its premise. It works with various name-brand tools and matches the power offered by the tool’s OEM battery. Its capacity also matches CEENR’s claims, which is rarely true with sketchier third-party power tool batteries.
