Ryobi identifies models RB4L20 and RB4L30 on its UK product pages; check the model number on your pack before assuming it has this feature.
How the USB-C power-bank feature works
On supported USB Lithium batteries, USB-C does double duty: it can charge the battery itself, and the battery can use that port to supply power to a mobile device. Ryobi describes the RB4L20 as a power bank and battery that can charge a mobile phone, while its RB4L30 listing says it can charge mobile devices. The Australian 2Ah listing also mentions small electronics such as smartwatches.

This is a feature of certain USB Lithium packs—not a general feature of every Ryobi battery. Do not assume a battery from another Ryobi voltage platform has USB-C power-bank output.

What the capacity numbers do—and do not—tell you
The 2.0Ah and 3.0Ah labels identify the capacities Ryobi states for the UK RB4L20 and RB4L30. They are not enough to calculate how many phone charges you will get. Ryobi’s cited product information does not specify USB output wattage or protocol, or promise a particular number of charges or a full charge for a given phone.
Actual results can depend on the phone and its battery, the power being drawn while connected, and other conditions. Treat this as a convenient way to top up a compatible device, not as a guaranteed substitute for a dedicated power bank.

How to use it and charge the battery
- Confirm the model. Find the model number on the pack and compare it with the product page or manual for your market. The documented UK examples are RB4L20 and RB4L30.
- Connect the mobile device to the pack’s USB-C port. Ryobi describes using this port to charge a phone or other mobile device. The cited product descriptions do not state an output protocol or wattage.
- Use the battery’s fuel gauge if available. Ryobi says the RB4L20’s fuel gauge can be checked by pressing and holding its button.
- Recharge the pack as its instructions specify. Ryobi describes USB-C charging and, for the UK RB4L20, charging with a USB Lithium ported charger. The operator manual’s USB-C guidance says to disconnect the cable and power source when the battery is fully charged.
Check the exact product bundle before buying a cable or charger: included accessories can vary by model and market. For the Australian 2Ah listing, Ryobi mentions a USB-A-to-USB-C cable; that does not establish what comes with UK products or other packs.
