To ensure a proper connection and delivery of frequencies through the magnetic coil, the A/C power cord is designed to fit tightly into your HAELO device. If inserted incorrectly, the power cord may feel loose and/or your HAELO will shut off during a session or when moved. If you have experienced any one of these issues, use gentle force to push the power cord's female end into the device's male end (approximately 5/8"). 

Please refer to the photos below to gauge the depth to which you need to insert your cord into the back of your HAELO device. If you continue to experience issues, please contact us at
