How to open up and look for problems with your Stanley fat max jumper box￼
Hey youtube: it's vince here, hey! I looked on the internet for videos about trying to fix one of these stanley fat max jumper boxes.
I've had them for a couple of years, and performance has been okay and started to taper off and uh.
I said: well, maybe there's a way to like take it apart, replace the battery.
Something like that.
I love this thing because it's got its own charger here.
You just plug in an extension cord usb charging air compressor inside of it a little led, uh battery status and a little led light and an alternator check which I've never even used, but uh anyway hook up your cable, it's positive and negative, and it's got one of those polarity reversing things.
So you can't mess it up.
So I bought two of them and, like I said, the performance has not been uh up to par lately, so I opened it up and uh surprised to what I found.
So let me show you the top here.
Uh these two black pieces on the ends will come off they're like guards on the top.
It's a five millimeter hex that you uh undo four of these across here and then the bottom is just uh phillips screws.
So I'll pull these out and I'll show you what I found so the four hex screws uh come out pretty easy, uh nice looking little cap screw for the top on the bottom is where the other screws are that hold these two pieces on and also just hold the bottom cover on uh.
So some of them are quite deep.
You'll need a longer screwdriver uh phillips like this to get down in here and get these screws out and there's four screws here on the surface that take these two pieces here off so I'll go ahead and zip those off real, quick and show you how that works.
So I took it again.
I took the two or the four hex cap screws off at the top, and this just comes right off here.
The uh cable is just clipped into it.
I'm just going to leave it hanging off the side there, but it gives you access to the rest of this thing.
Let me get the other side off and now we've got uh about nine or ten phillips screws that are holding this case in, but again it's uh pretty easy to get to they're just phillips.
All of these screws are the same, except for one of course, and that one is right here: the hole is slightly smaller and the screw you'll see is slightly smaller.
So again, that's this hole right here, just remember where it's at mark it, if you need to for when you put it back together, so now get this this cover off and if you left any of them not fully unscrewed you'll find that out now I told you I like the features of this thing.
The build quality is not bad.
It's typical made in china stuff, but uh.
Now you can see inside this is the battery of course takes up most of the room.
Here's a little air compressor and I've used this thing.
I had a flat tire when I got back from a trip after three days in the parking lot plugged.
This hooked this thing up used the battery, ran the air compressor for about eight or ten minutes put 30 psi in it was a slow leak, so I drove home, took it to the tire shop, the next day, uh.
So anyway, here's what it looks like on the inside, but let me show you something else: okay, so took the back off of the stanley fat max power jumper, here's the battery obviously takes up most of the inside of it.
There's a little air compressor over here, and you know the unit's relatively new.
It's just not taking a charge, but once I opened into it started, taking a look.
These screws that hold the uh cables under the posts are actually loose.
The nut see that the nut is loose on both of these.
So I'm going to tighten this thing back up and hope that it'll uh it'll take a charge and uh give me some more life I'll.
Let you know all right so tightening these posts up maybe put a little thread locker on them, something like that to make sure they don't vibrate loose, because these ride around on our cars.
We have two of them: they ride around our cars, all the time that vibration might work those screws out uh after a while, but then putting it back together, make sure that this little black uh piece that covers the uh, the charger plug, is just kind of sitting there, and then it lines up with this little cutout right here in the uh, the back cover.
So that's really, the trickiest part is kind of getting that lined up and then oh by the way, take all the screws out.
A lot of them will want to stay in there uh, but trust me it's easier if you take them out and that way when you're putting them together, you know which ones don't have screws or which ones do they all have the screws removed and then also you got to kind of look through and line up the holes they don't line up perfectly again.
This is a plastic uh piece of gear made.
You know in china and, like I said, build quality is not horrible, it's pretty heavy and pretty solid, but of course it's not up to the standards of some tools.
You might be used to, but anyway, the other thing I wanted to tell you was there's actually two of these smaller screws, so there's like 10 of the full full-sized screws and there's two smaller screws and they go as you look at the label on the back in the bottom uh right, corner uh here and then underneath the uh, the handle that we're going to reattach.
So we'll zip the screws back in and should be ready to opt check.
It put it back in the vehicle and it's ready to assist with full charge all right.
All the phillips screws are in the bottom, there's the fourth hex screw in the top of the handles it's all back together and ready to go back in the trunk.
A couple of pro tips for you.
First of all, these things, you know, make us lazy and uh the problem with working with plastic metal screws in plastic.
With these things, is you can't strip them off? So don't be afraid to? You know, start them with the driver and then just use a good old-fashioned screwdriver.
So you don't get them too tight and strip.
That plastic in there, the other uh pro tip for you, is on the bottom of mine.
It was sliding around the trunk, and I got some of this heavy uh velcro and I just put the uh like the male side of it, four patches of that on here and uh.
Now it it sits, put and the trunk doesn't slide around when I'm hanging those curves and hitting the brakes and whatnot.
So anyway, again, the stanley fat max, like I said, a pretty good piece of gear uh when that battery does go out- and I know it only lasts three or four years I'll- probably try and find another battery the rest of the units, all functioning and just uh, replace the battery and keep using it uh anyway.
I hope this helps.
If you have problems with it, don't just throw it away, open it up and see if those cables are loose.
We'll see you next time.
