Introduction
The Insignia All-In-One Travel Adapter/Converter is designed to provide power compatibility for your electronic devices when traveling internationally. This device combines multiple plug configurations and a voltage converter to accommodate various global power standards. It is suitable for use with most low-wattage electronics and high-wattage heating appliances up to 1875W.
Important Safety Information
Please read all safety instructions before using this product to prevent injury or damage.
- Do not use with non-heating appliances over 50W. This product is primarily designed for heating appliances (e.g., hair dryers, flat irons) when in converter mode.
- Always check the voltage requirements of your device before plugging it into the adapter/converter. Incorrect voltage can damage your device.
- Ensure the adapter/converter switch is set correctly for either 'Adapter' or 'Converter' mode based on your device's needs and the local voltage.
- Do not immerse the unit in water or expose it to excessive moisture.
- Keep out of reach of children.
- Unplug the unit from the wall outlet when not in use.
- Do not attempt to disassemble or modify the unit. Refer all servicing to qualified personnel.

Key Components:
- Universal AC Outlet: Accepts various plug types from different countries.
- Integrated Plug Adapters: Retractable prongs for USA/China, Europe, UK, and Australia.
- Adapter/Converter Switch: Selects between voltage conversion and simple plug adaptation.
- Power Indicator Light: Illuminates when the unit is receiving power.
Setup
Before connecting your device, ensure the correct plug type is extended and the mode switch is set appropriately.
Extending the Correct Plug:
- Identify the type of wall outlet in your destination country.
- Locate the corresponding slider on the side of the adapter/converter. The sliders are typically labeled for regions like USA/China, Europe, UK, and Australia/China.
- Slide the appropriate button to extend the required plug prongs. Ensure the prongs are fully extended and locked into place before inserting into a wall outlet.

Operating Instructions
The Insignia Travel Adapter/Converter offers two modes of operation: Adapter and Converter.
Understanding Adapter vs. Converter Mode:
- Adapter Mode: This mode simply changes the physical plug shape to fit the wall outlet. It does not change the voltage. Use this mode if your device is dual-voltage (e.g., 100-240V) and can handle the local voltage directly. This is typically for devices like laptops, phone chargers, and cameras.
- Converter Mode: This mode transforms higher foreign voltage (220-240V) down to the North American standard (110-120V). Use this mode for single-voltage North American devices (110-120V) that are high-wattage heating appliances, such as hair dryers, curling irons, or travel irons, up to 1875W. Do not use converter mode for sensitive electronics like laptops, phones, or battery chargers, as it can damage them.
Using the Adapter/Converter:
- Determine your device's voltage requirements: Check the label on your device or its power supply.
- Identify the local voltage: Research the standard voltage of your destination country.
- Select the correct mode: Move the switch on the adapter/converter to either 'Adapter' or 'Converter' based on your device's voltage and wattage, and the local voltage.
- Extend the appropriate plug prongs for the wall outlet.
- Plug your device into the universal AC outlet on the front of the adapter/converter.
- Insert the adapter/converter into the wall outlet. The power indicator light should illuminate.
- After use, unplug the unit from the wall outlet first, then unplug your device. Retract the prongs for storage.
Maintenance
Proper care ensures the longevity of your Insignia Travel Adapter/Converter.
- Cleaning: Disconnect the unit from power before cleaning. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the adapter/converter in a cool, dry place away from direct sunlight and moisture. Ensure all prongs are retracted before storage.
- Inspection: Periodically inspect the unit for any signs of damage, such as frayed cords or cracked casing. Do not use if damaged.
Troubleshooting
If you encounter issues with your Insignia Travel Adapter/Converter, refer to the following common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on. | No power from wall outlet; incorrect plug extended; adapter/converter switch set incorrectly; device incompatible. | Check wall outlet with another device. Ensure correct plug is fully extended. Verify adapter/converter switch is in the correct mode (Adapter or Converter). Confirm device is compatible with the selected mode and local voltage. |
| Device damaged after use. | Incorrect mode selected (e.g., using converter mode for sensitive electronics); device wattage exceeds converter capacity. | Always ensure 'Adapter' mode is used for dual-voltage electronics. 'Converter' mode is only for high-wattage heating appliances. Do not exceed the 1875W maximum capacity. |
| Adapter feels hot. | Normal operation for high-wattage devices; prolonged use; overloaded. | Some warmth is normal, especially in converter mode with high-wattage devices. If it becomes excessively hot or emits smoke/odor, immediately unplug and discontinue use. Ensure total wattage of connected devices does not exceed 1875W. |
| Prongs do not extend or retract smoothly. | Debris or mechanical issue. | Ensure no foreign objects are obstructing the mechanism. Do not force the prongs. If the issue persists, the unit may be damaged. |
