The emWave PSR is designed to be charged via a standard USB connection. Whether you are using the original wall adapter or a third-party replacement, it is important to match the voltage and amperage specifications to ensure the longevity of the internal battery and the safety of the device.
Technical Specifications
-
Input Voltage: 100 – 240V AC (for the wall adapter)
-
Output Voltage: 5.0V DC
-
Output Current (Amperage): 1.0A (or 1000mA)
-
Connector Type: Standard USB to the proprietary emWave PSR charging cable.
Charging Methods
-
Computer USB Port: You can plug the emWave PSR charging cable directly into any powered USB port on a laptop or desktop computer. These ports typically output 5V at 0.5A or 1.0A, which is perfectly safe for the device.
-
Wall Adapter: If using a wall plug, ensure the “Output” section on the label reads 5V. While a higher amperage (e.g., 2.1A or 2.4A) is generally safe because the device will only “draw” what it needs, never use a charger with a voltage higher than 5V (such as 9V or 12V “Fast Chargers”), as this can damage the internal circuitry.
Important Charging Notes
-
Cable Specifics: The emWave PSR uses a specific charging cable. Ensure the cable is firmly seated in the device to maintain a consistent charge.
-
Charging Status: On the PSR, the lights will indicate the charging progress. Once the battery is full, the charging sequence will stop or indicate a full state.
-
Battery Maintenance: To keep the internal battery healthy, avoid leaving the device completely discharged for long periods. Even if not in regular use, it is recommended to charge the device every few months.
