battery’s status, press the DISPLAY
button on the front of the PP-18400CI.
The display will show the voltage of
the internal battery.

18400CI inverter, the digital display
shows the wattage and voltage of
the device being powered. Push the
DISPLAY button to read wattage
or push DISPLAY button again to
read voltage. The internal battery is

CHARGING INTERNAL BATTERY
NOTE: Internal battery’s status DISPLAY
is most accurate when the Portable Power
PP-18400CI has been disconnected from
all devices and charging sources for at
least 30 minutes. The DISPLAY feature
will not work when the Portable Power is
being charged.
CAUTION: Operating the Portable Power
PP-18400CI while the internal battery is
being charged may cause permanent
damage to the PP-18400CI.
1. To check the internal battery’s charge
level, press the DISPLAY button. The
Digital Display will show the battery’s
voltage.
2. To charge, follow instructions
CHARGE INTERNAL BATTERY on
page 4.
3. Once the battery is fully charged,
the built-in charger automatically
switches to oat-mode monitoring,
which trickle charges the battery
and keeps it fully charged without
overcharging so the PP-18400CI may
be left permanently connected to the
electrical wall outlet.
