Using the Inverter5.3
It is important to know the continuous wattage of the device you plan to
use with the inverter. The Instant Power™ must be used with devices
drawing 400 watts or less. If the wattage is not marked on the device, use
only devices that draw less than 4 Amps of AC current.
Devices like TVs, fans or electric motors require additional power to start
(commonlyknownasthe“startingorpeakpower”).TheInstantPower™
can supply a momentary surge in wattage; however even devices rated
less than the maximum 400 watts can exceed the inverters surge capabil-
ity and cause an automatic overload shutdown.
Do not use the inverter with a product that draws a higher wattage than
the inverter can provide, as this may cause damage to the inverter and the
product.

wave inverter.
Always run a test to establish whether the inverter will
operate a particular piece of equipment or device.
NOTE: In the event of a power overload, the inverter is designed to auto-
matically shut down. This safety feature prevents damaging the inverter
while testing devices and equipment with the 400 watt range.
NOTE: If powering more than one device, start one device at a time to
avoid a power surge and/or inverter overload. The surge load of each
device should not exceed the inverter’s continuous operation wattage rate.
Powering a 120V AC Device5.4

again in quick succession. If this procedure is not successful, it is likely
that the inverter does not have the required capacity to operate the
device intended.
Charge the Instant Power™ as soon as possible after each use.4.
Risk of electric shock.
Incorrect operation of your inverter may result in damage and
personal injury. The inverter output is 120V AC and can shock or
electrocute the same as any ordinary household AC wall outlet.
