Recharge ac cant find a/c charge ports

Refer to the instructions that came with charger. If you threw them away you have a problem You can go on line and download instructions.
Low Charge Alert (LCA)
On the front of the unit there is a Low Charge Alert port. There is a red plug in this port. With the plug
removed, when the battery level drops to LO, an alarm will sound to remind the user to recharge the
Jump-Starter.
The alarm can be turned off one of three ways:
•
Placing the pin back into the Low Charge Alert port
•
Recharging the battery immediately to bring it to the capacity of 10% or more
•
Pressing the battery indicator display button. If the alarm is turned off by pressing the battery
display button, the alarm will sound automatically again in approximately 1 hour.
The alarm will only be turned off permanently if the battery is in a fully charged state, or the pin is
inserted in the Low Charge Alert port. There is a storage port on the back of the Jump-Starter for the
LCA plug. When the plug is removed from the LCA port, it should be installed in the storage port on the
back of the Jump-Starter.
Charging Jump-Starter Battery
All rechargeable batteries gradually discharge when left idle, and you need to recharge them
periodically to maintain maximum battery capacity. The AC charger plug within the Jump-Starter is
designed to charge using a 110/120-volt outlet.
•
Fully charge unit to the recommended maximum and initial charge time of 24 hours. Thereafter, an
AC typical charge time is 8 to 12 hours.
•
Recharge the unit fully after each use. This will prolong the life of the battery because frequent
discharges between recharges will reduce battery life.
•
Make sure all functions of the Jump-Starter are turned off during recharging

Hope this helps
God blessss

The port in the larger of the 2 AC lines from the compressor is the port you charge at.

trace the ac lines from the ac radiator to the firewall. The port should be in those lines.

YOU NEED A R-134 GAUGE SET TO CHECK LOW PRESSURE SIDE AND HIGH PRESSURE SIDE.YOU ALSO CAN BUY A LITTLE CHEAPER GAUGE TO CHECK YOUR AC LOW BLUE SIDE AND HIGH RED SIDE AT ANY AUTO ZONE OR ADVANCE AUTO PARTS.WHAT YOU DO WHEN YOU GET YOUR GAUGE SET HOOK GAUGE TO LOW PRESSURE SIDE BLUE CAP PORT AND GAUGE TO HIGH SIDE PRESSURE RED CAP PORT.YOU CRANK CAR UP GET IT OPERATING TEMPERATURE.THEN TURN AC ON HIGH COOL LET RUN 3 TO 4 MINUTES.CHECK LOW SIDE GAUGE READING SHOULD BE 28 - 32 PSI. HIGH PRESSURE SIDE GAUGE SHOULD 199 - 228 PSI. THATS NORMAL CHARGE. SEE YOU CANT JUST RECHARGE AC SYSTEM UNTIL YOU CHECK IT FIRST YOU WILL DAMAGE SYSTEM .NOW YOU CAN GO TO AUTO ZONE PARTS BUY A CHARGE CAN WITH GAUGE AND HOSE.ATTACH TO IT.YOU NEED MORE THAN ONE CAN.WARNING MAKE COMPRESSOR IS RUNNING WHEN YOU TURN ON AC .BECAUSE IF COMPRESSOR NOT RUNNING CHECK FUSE AND AC COMPRESSOR RELAY.IF BOTH OKAY.YOU COULD HAVE OPEN CLUTCH COIL A FAULTY LOW PRESSURE SWITCH WILL CAUSE AC NOT TO WORK. IF LOW PRESSURE GAUGE BLUE SIDE PRESSURE IS 28 OR 30 YOU DONT NEED A CHARGE.PROBLEM SOME WHERE ELSE.BE SURE TO WEAR SAFETY GLASSES WHEN WORKING ON AC SYSTEM.

mcdevito75 here, The low side of you A/C is the side you charge, follow the silver lines commimg out the firewall, they hook up to the evaporator under the dash, look for the charge port on this line from the firewall. The recharge kit you buy will only fit this port, also the port may be covered with a brass ;looking cap un screw this cap and the valve looks like the tire valve. Also follow the chargeing instructions carefully.

do not rechare unless you have gauges take it to shcucks or pep boys you over charge the system you can kiss $400.00 good buy. tkse it to a guy who has gauges and can tell whats going on. over charging is not good no matter what.

You can only attach the the recharge hose from the kit to the low side ( A/C service port) and the cap should be blue with a leter L on it. Good luck and follow the instruction and don't over charge the system. With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold - STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system. And actually the best way to insure the proper charge is in a system, is to use an AC machine to recover the R134a and then evacuate and recharge the system with the correct amount. Most cars have the specified amount on a decal under the hood.  Good luck and hope this helps.

follow the larger ac line of the to sizes until u come to a port it is the low side ,is the smaller port this is what u want
