Tera EV Charger User Guide and FAQ
Attention
- Working Voltage: Recommended 220V or 240V.
- Outlet: Compatible with NEMA 14-50 plugs only.
- Hybrid vehicles automatically reduce charging current based on the electric car's maximum allowable current.
- Please use our NEMA 5-15P to 14-50R adapter cord with the Tera EV charger to ensure compatibility. Others may not work. Our NEMA 5-15P to 14-50R adapter cord is intended for EV charger use only and should not be used for regular household purposes.
- For your safety and in accordance with American electrical safety standards, the maximum current for a 5-15 electrical outlet should not exceed 15 amperes.
- When the Tera portable electric vehicle charger is connected to a 110V power source, the current will automatically adjust to 15A to charge your car, and this cannot be changed.
- Please note that charging at 15 amperes on a Level 1 mode and 110 volts will be quite slow! Overnight charging may only provide enough power for your electric vehicle to travel approximately 60 to 80 miles.
- Adjusting the current during charging may cause charging issues. Please do not plug in your car before making current or schedule time adjustments.
- If you don't want to use the APP, long-press the [A button] on the screen to switch to "Plug and Play" mode.
The following are the current levels adjustable using the app and screen button under 240V and 120V voltages, respectively. If you encounter any issues with current adjustment, please contact us for an OTA upgrade.
| 240V | 120V | |
|---|---|---|
| Default Current | 32A | 12A |
| Screen Button | 16A/20A/24A/32A | 8A/10A/12A/15A |
| Smart Life APP (Gradually adjust by 1A) | 8A-32A | 8A-15A |

FAQ
Q: How to Connect to the App?
- Before connecting to the charging station for the first time, please ensure your phone's WiFi and Bluetooth are enabled to facilitate successful pairing with the Tera portable charging station after downloading the app.
- Search for the "Smart Life" app in the app store, download it, and register.
- Open "Smart Life" app, tap the "Add Device" button, and search for your EV Charger. Add it once it appears.
App screenshots illustrate the connection process: showing initial setup, Wi-Fi connection, device discovery, and successful addition.
Q: Why Can't I Find the EV Charger on the App?
- Make sure your phone is connected to 2.4Ghz WiFi, not a network with a 5G suffix.
- Ensure that both WiFi and Bluetooth are enabled on your phone. The "Smart Life" app will only function correctly when the EV charger and the phone are connected to the same WiFi network.
- WiFi Reset: Unplug the charging gun and simultaneously long-press the [A button] and the [Time button] on the screen until "WiFi Reset" is displayed. If there is a lag during the reset process, it is recommended to disconnect the power and restart.
- Please try to restart your "Smart Life" app to add your EV Charger.
Q: How to Adjust Current?
Method 1: Adjust the Current from 16A to 32A by briefly tapping the [A button] on the screen.
Method 2: Open the "Smart Life" app and connect to the EV Charger. Navigate to the "Charging pile" page and tap the third button in the bottom right corner. Locate "Charging current" and tap it to adjust the current.
(Note: Adjusting the current while charging may cause charging issues. Please stop charging before making adjustments.)
App screenshots show the steps: accessing the "Setting" tab, then selecting and adjusting the charging current from available options (e.g., 0/16/20/24/32A).
Q: How to Schedule Charging Time?
Method 1: Unplug the charging cable and short-press the [Time button] on the screen to delay the charging time. Charging will start when the screen displays "Wait 00:00:00."
Method 2: Open the "Smart Life" app, add your device, and then schedule the charging time.
(Note: The time displayed for scheduling, either on the screen or in the app, is not a specific time but a delay timer.)
App screenshots demonstrate scheduling: selecting "Delayed charging" and setting a desired duration (e.g., 10, 11, 12 hours).
Q: Why Does It Show "Lowvolt Fault"?
Tera Portable EV Charger is designed to operate at a voltage range of 220V-240V.
If your voltage is 240V, it will charge at a rate of 7.6kW with a maximum current of 32A. If your outlet voltage falls below 200V, it will display "Lowvolt Fault" and will not operate.
