4iiii Innovations - Power Meters
Third-party tested to +/- 1% accuracy, all 4iiii power meters come with our patented 3D strain gauge technology and an industry leading 3 year warranty. The PRECISION 3+ and PRECISION 3+ PRO Powermeters have Apple Find My integrated to allow Apple users to track the location of their power meters.
All of our power meters are ANT+ and Bluetooth (BLE) compatible meaning that you can receive from your 4iiii power meter on your preferred ANT+ device or connect it to your laptop or tablet to use your power meter over BLE with your favorite indoor training app. This means that the power numbers that you see Zwift or TrainerRoad will be consistent with the numbers that you see outside.
