Yes—some Ryobi USB Lithium batteries can double as USB-C power banks. Ryobi’s UK product pages document this for the RB4L20 (2.0Ah) and RB4L30 (3.0Ah): connect a mobile device to the battery’s USB-C port to charge it. Check the model number on your pack first; this feature is documented for specific USB Lithium batteries, not Ryobi batteries generally.
How the USB-C power-bank feature works
A compatible Ryobi USB Lithium battery can power tools in the USB Lithium range and supply power to a mobile device through its USB-C port. Ryobi describes phone or mobile-device charging on its UK pages, and its Australian page also mentions topping up small electronics such as smartwatches.
To use it, connect your phone or other device to the battery’s USB-C port with a suitable cable. The product pages do not specify output wattage or charging protocol, so they do not establish how quickly a particular device will charge.
Which Ryobi USB Lithium batteries have this feature?
The cited UK listings identify two models as batteries and power banks. Compare the stated details below, and use the model number—not just the Ryobi name—to confirm what you own.

Ryobi Australia product page |
What the capacity figures do—and don’t—tell you
The UK RB4L20 is labelled 2.0Ah and the RB4L30 3.0Ah, but those figures do not establish how many times either battery will charge a phone. Ryobi’s cited product information gives no phone-charge count, guarantee of a full phone charge, or measured output comparison between the models. Phone and battery conditions also matter, so do not treat a capacity label as a promise of a particular number of charges.
Charging the battery and checking the exact pack
Ryobi says the UK RB4L20 can itself be charged by USB-C or with a USB Lithium ported charger. Its UK page also describes a press-and-hold button for checking the battery fuel gauge. The Australian 2Ah listing accepts USB-C charging cables and specifies an included USB-A-to-USB-C cable for that product listing. Accessories can differ by model and market, so confirm what is in the box before relying on a cable or charger.
