Introduction
My Stanley J5C09 power station (jump starter and air compress/tire inflator) stopped working. The 12 volt DC power adapter failed.
The adapter is inside of the product case, with the AC plug sticking out of the case. Instead of trying to find an exact replacement part, I used a generic 12 volt DC, 500ma, 110 VAC power adapter.
In the hole in the case where the original power adapter fit, I put in a barrel jack.
I made a 3D printed plastic part to mount the jack.
Bonus: I can now recharge the power station with any 12 volt DC source, such as a solar panel.
What you need
-
-
The most likely failure on this device is a dead battery. But, you also might have a failed power adapter.
-
Plug in the power cord.
-
Check the indicator lights. The "low" light should be on. If it's not, chances are that the power adapter has failed.
-
If the "low" light is on, this isn't the repair guide for you. Something other than the power adapter has failed.
-
-
-
Important: Turn the power switch to off! Unplug and remove the power cord.
-
Remove the screws from the outside edges of the rear of the power station case. (No need to remove the screws that hold the compressor module to the case.)
-
Gently pull the two halves of the case apart. Feed the jumper wire cables into the case so there is room to open it.
-
-
-
Remove the two screws holding the power adapter in place.
-
Cut the power adapter wires, leaving about 1" on the power adapter side. Strip about 1/4" inch of the insulation on the two wires coming out of the power adapter.
-
Check the power adapter with your multimeter.
-
Set the multmeter to DC volts.
-
Connect the multimeter probes to the two wires coming out of the power adapter.
-
Plug in the power adapter.
-
Is the meter showing 13 volts DC or more? If so, you power adapter is probably OK. There's some other reason your power station isn't charging. This guide won't help.

-
-
-
You could simply drill a hole somewhere in the power station case to mount the barrel connector
-
Or, you could 3D-print a plate to neatly cover up the hold where the power adapter was originally.
-
The 3D design is on thingiverse.com
-
Print it. No supports needed.
-
-
-
Place the power jack plate into the case in the hold where the power adapter was.
-
You may need to trim the plate to fit the case.
-
Drill small holes into the case to match the (4) holes in the plate.
-
Use (4x) 2mm x 5mm sheet metal screws to attach the plate to the case.
-
-
-
Strip the wires that used to connect to the power adapter, about 1/4".
-
The wire with the "- - -" stripe pattern is the negative. Connect this to the barrel jack terminal that is connected to the outer ring of the jack.
-
Connect the other wire to the terminal connect to the center pin.
-
Use your multimeter's continuity test feature to verify the barrel jack connections.
-
Solder the wires to the barrel jack.
-
-
-
Remove the nut from the barrel jack
-
Insert the barrel jack into the plate
-
Tighten the barrel jack nut.
