This safety feature prevents damaging the converter while testing devices and
equipment within the wattage range of the converter.
When using the vehicle's 12 volt accessory port, this converter is designed to
supply 60 to 70 watts when the vehicle is not running. With the vehicle's engine
running, it can supply up to 100 watts. To use the full output, you must connect the
converter directly to your battery.
NOTE: The 100 watt limit is to accommodate the fuse ratings for all vehicles.
Some vehicles may allow the full output. If the fuse blows when you switch on the
device you are trying to use, you have to either use a smaller device or you must
connect the converter directly to the battery.
IMPORTANT: This converter uses a modified sine waveform (diagram A)
which is not quite the same as power company electricity (diagram B). For the
following devices, we strongly recommend that you use caution and check the
device's manual to make sure it is compatible with modified sine waveform.
1. Switch mode power supplies
2. Linear power supplies
3. Class 2 transformers
4. Line filter capacitors
5. Shaded pole motors
6. Fan motors
7. Microwave ovens
8. Fluorescent and high intensity lamps (with a ballast)
9. Transformer less battery chargers
Using the converter with any of these devices may cause the device to run
warmer or overheat.

IMPORTANT: If you are using the power converter to operate a battery
charger, monitor the temperature of the battery charger for about 10
minutes. If the battery charger becomes abnormally warm, disconnect it
from the converter immediately.
NOTE: You can use an extension cord from the converter to the device without
significantly decreasing the power being generated by the converter. For best
operating results, the extension cord should be no longer than 50 feet.
