This article details a practical test exploring the use of readily available Ryobi 18V batteries as a cost-effective emergency power source for the EcoFlow River 2 portable power station. Instead of investing in expensive proprietary accessories, this project leverages the DC output of common Ryobi batteries, utilizing a simple adapter and connector to interface with the power station's DC or solar input. The focus is on creating a convenient and resourceful backup power solution for situations where grid power is unavailable.The experiment involved connecting a suitable DC adapter to the Ryobi battery and then to the EcoFlow River 2. The process, described in detail, highlights the simplicity and versatility of the setup, including the ability to use multiple batteries for increased power output. The results demonstrate the feasibility and practicality of this approach, showcasing a significant increase in the power station's capacity with minimal additional cost or complexity. The test analyzes efficiency and explores the trade-offs between capacity and convenience.
Pros And Cons
- Relatively inexpensive solution if you already own Ryobi batteries and charger.
- Works as a backup power source for power stations with DC input.
- Easy to connect with an XT60 connector (or other DC connectors).
- Power output may be limited depending on the battery's condition and age. (Observed approximately 50-55 watt-hours from a 72 watt-hour battery).

Extending Power Station Life with Ryobi Batteries
This project explores using readily available Ryobi 18V batteries as an emergency power backup for portable power stations, specifically the EcoFlow River 2. This method offers a cost-effective alternative to purchasing dedicated power station accessories. The core idea is to leverage the DC output of the Ryobi battery, utilizing a suitable adapter and connector to interface with the power station's DC input or solar input.

The process involves connecting a DC adapter designed for Ryobi batteries to the power station. This adapter usually features a fused output for safety. It's crucial to ensure compatibility between the adapter's connector and the power station's input, and to properly secure the connections. This approach eliminates the need for additional charging equipment, making it convenient and resourceful.

Connecting the Ryobi Battery and Adapter
A simple XT60 connector was used to connect the Ryobi adapter to the power station, but other DC connectors can be employed depending on compatibility. Heat shrink crimps were sufficient to secure the connection in this test, although soldering or using quick connect connectors provides more robust solutions. The adapter's built-in power switch allows for safe connection management. This feature allows for easy interruption in case of issues.

The versatility of this setup is highlighted by the possibility of using multiple batteries in parallel or series. This configuration allows for adjustments to the voltage and current output depending on the power station’s requirements. For this specific test, a single 18V battery was utilized, well within the EcoFlow River 2’s maximum input wattage.

Testing and Results
The EcoFlow River 2 successfully recognized the 18V input, registering approximately 109 watts. This is comparable to using the car charger input. The test was run for nearly half an hour, resulting in a 20% increase in the power station's capacity. This translates to roughly 50-55 watt-hours of added power from the Ryobi battery.

While the Ryobi 18V battery is rated at 72 watt-hours, the test only utilized a portion of its capacity before the power drop indicated a voltage decrease, preserving battery lifespan. Even with this partial discharge, the results demonstrate the practicality of this method for extending the usability of a portable power station.

Conclusion and Comparison
This project successfully demonstrated the feasibility of using Ryobi 18V batteries as an emergency power source for portable power stations. This method is cost-effective as it leverages existing tools and batteries, requiring minimal additional purchases. The simplicity of the setup and the ability to adjust voltage and current via battery configuration add to its practicality.

Compared to using larger lithium iron phosphate batteries, this method eliminates the need for a separate charger for the emergency backup. While larger batteries offer greater capacity, this approach offers a balance of convenience and sufficient power for short-term backup needs in emergency situations. The initial investment is minimal, primarily for the adapter and connector.
