7.1 AC RECHARGE
AC recharge requires the use of the supplied AC/DC adapter. The adapter must be powered
from 120 volt AC, 60 Hz North American standard household AC outlets. The battery status
display will automatically activate during AC recharge. As recharge progresses, the red LEDs
will light one by one. Charge the Power City until the battery status display lights the green
FULL LED. Continue to recharge for one to two hours, and then disconnect the AC Recharger.
AC recharge is an automatic float and taper charge and The AC Recharger can be left
connected to the main unit for long periods. See Figure 2 for AC recharge connection to the main
unit. Refer to Section 7.2 for recharge method.
Make sure that the inverter, compressor and lamp on/off Switches are in off position during
AC
recharging.
7.2 DC RECHARGE
Power City is supplied with two accessory cables. One cable is a black Inverter power cable with
an attached thinner lantern extension cord. It is to power the inverter when it is used with another
accessory outlet in a vehicle or boat. An attached thinner wire is dubbed lantern extension cord”
and it is used to power the lantern. The DC recharge cable has red and black wire and it mates
with the inverter power cable to make a DC to DC cable.
After recharge, the accessory cables are stored in their own cable storage hatch in the main unit.
Recharging the main unit’s internal battery from an external DC power source requires the use
of the DC recharge cable and the inverter power cable. (See Figure 12) The lantern extension
cord can be connected to the lantern to simultaneously recharge the main unit and power the
lantern (not shown).

Make sure safety on/off
Switch, inverter, and compressor switches are in the off position during
DC recharging.
Unlike the AC recharge method, DC recharge does not automatically activate the battery status
display. To check the battery status, press the Battery Status Display Push-button. If the jump- starter’s
battery is fully discharged, it is recommended that the host vehicle or boat’s engine being used for
recharging be left operating while the unit is being charged using the 12 volt DC/DC method.
WARNING:
DO NOT recharge main unit for more than 8 hours maximum using 12 volt DC
method. Do not charge lantern for more than five hours using the dc recharge method.
1. Remove both power cables from the cable storage hatch.
2. Insert the red DC recharge cable’s rectangular connector flat pins into the black rectangu-
lar connector on the inverter power cable.
3. Insert black DC plug on the inverter power cable into a DC accessory socket on the
main unit.
4. Plug the red DC plug into an accessory socket in a vehicle, power supply or other 12 volt
DC source.
