Schumacher PIC-150-USB - Manual (Page 4)

• 3 •
This safety feature prevents damaging the inverter while testing
devices and equipment within the wattage range of the inverter.
IMPORTANT: This inverter is designed to power 100-watt devices or
less when used with the vehicle’s 12-volt accessory port. To use the
full output, you must purchase a 12-volt accessory outlet to battery
clips adapter (Schumacher Model SAC-103) and connect the inverter
directly to the 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 must either
use a smaller device or purchase the 12-volt accessory outlet to
battery clips adapter (Schumacher Model SAC-103) and connect the
inverter directly to the battery.
IMPORTANT: This inverter uses a nonsinusoidal waveform.
Therefore, we do not recommend you use it to power the
following devices:
