When I go to the grocery store i take my backpack cooler, my kryptonite lock, a small tool pouch, and reusable grocery/produce bags.

All my groceries go into this cooler backpack. I also keep reusable produce bags, and grocery bags in it. On the way to the store putting my lock in the backpack works, but on the way home it does not, because it is full of groceries.
I also have a small tool pouch with a handful of hex wrenches. It is fine to go into the backpack.
I also volunteer at a food bank. When I go there i also bring my charger because I get 3 hours of free charging.
This all starts to take up a lot of space in my backpack, so i have been carrying a sling bag, i have to wear it on my chest. Today it was really getting in the way of things.
I am looking for something to carry my lock, and my charger while wearing my backpack.
Update to ad my scooter models
Current, InMotion S1F, my wife it’s taking it when the new one arrives):

New, InMotion RS Jet, as soon as it arrives, it is currently lost in the Fedex Network:

You might consider something like a hip pack or chest rig? On my bike I have used a sling back and backpack in conjunction, with the backpack kind of perched on top of the sling bag and secured with a chest strap: I’ve found this to be a reasonably stable setup (though on a scooter you might need to make some adjustments).
Also, what scooter do you use? The design might open up some onboard storage options.
P.S. I’ve featured your post in the community to help you get more feedback. Good luck!
I appreciate that.
No problem, I hope it helps!
I use a sling bag on my chest now, it has started to interfere with my handlebars, which has led me to an alternative. I used to wear the sling bag on my back under the backpack, but that has become growingly uncomfortable.
I have thought about a hip bag but have not found any so far that look like they would work.
Currently I am using an InMotion S1F, but it is getting replaced by the RS Jet as soon as it arrives, it is currently lost in the FedEx network.
I would love to figure out some on board cargo solutions, i am likely going to be working delivering for domino’s soon and would rather not use my Tacoma for delivering.
Current (my wife it’s taking it when the new one arrives):

New as soon as it arrives:

Check out Osprey: Their packs in general are 10/10 and they offer hip packs that include hydration.
For chest rigs, Hill People Gear is what I use, but there’s quite a few nice options out there.
You could look at storing some stuff on the stem/bars, but I’d recommend keeping that more to lightweight stuff as it can affect handling.
My sling bag is the Osprey Daylite Sling, and I have over of their backpacks. Love their stuff.
I’ve had their Aether for years (backpacking) and it’s been absolutely top notch.
my gf just puts her bag on the escoot foot well and wheels it around in the store, its smaller then a grocery trolley.
For the lock, I’ve seen designs on Thingiverse for 3d printed accessories that would mount the lock body to the stem of the escooter’s tiller (?), so that it doesn’t occupy space elsewhere. One concern I haven’t checked for is whether the lock would rattle too much, which could be a problem for a 3d printed attachment.
For the charger, I’m less certain, but maybe something like a cargo rack would work? I’ve seen a few which fit right above the rear wheel, with enough points to use a bungee cord to hold rectilinear objects in place.
I mount for the lock is a good idea.
This is my scooter, i have been trying to come up with a way to attach a cargo trailer to it.

Something like this may work to mount onto my steering arms: https://www.thingiverse.com/thing:4384624 although I think mine has a large diameter.
Since your e-scooter has dual steering tubes, I would suggest a lock-holding accessory that attaches to both. One complaint I have with similar lock accessories to the one linked is that they have the lock – which necessarily is made of solid metal – cantilevered out, resulting in a large moment arm. This means during sharp bumps in the road, the unsupported end of the lock will apply a torque to the plastic accessory, which inevitably ends in fatigue and breakage.
Some of this is down to necessity, because there’s no great way to hold onto a U-shaped lock at just one point. And also because the stock accessory for U-locks use this poor design. But in your case, you have two vertical tubes that can spread the load.
I think the ideal accessory in your case would be shaped similar to a wide halyard cleat arranged vertically, so that when the U-lock is opened, the U portion can be slid underneath the lower cleat and then locked to the top of the lock, which slides underneath the upper cleat. The act of locking snugly to the cleat will pin the lock in place while preventing cantilevering and noisy wobbling. Sadly, I’m not aware of such a ready-made design, but perhaps that’s something that a 3D printer enthusiast can help draft.
As for the cargo trailer idea, be aware that weight-and-balance need to be taken seriously for smaller configurations. I’ve written about trailers before – although for moving bikes behind a small automobile – and this is the relevant section:
Even if tongue weight were fine, the arrangement of the bikes on a hitch carrier have their own impact: moment of inertia. That is to say, if six bikes were arranged parallel to the drive axle, they’d have to each be spaced at least 8 inches (20 cm) apart. For six bikes, that means the carrier extends beyond the rear bumper by 48 inches (1.2 meters). And that’s just too much inertia to exert on a small car’s hitch receiver. Any bump that the car drives over would cause the bikes to also bounce, but that bounce then reflects itself due to the long moment arm, which then affects the car again. This is an identical wagging-the-dog scenario as trailers have, but here it’s a vertical wag rather than a lateral wag with a trailer.
In your case, imagine if you had a trailer and then came up to a speed bump. The front and rear e-scooter wheels have suspension, so they can absorb most of the bump as you roll over it. But most trailers don’t, so the trailer will jump up at its axle. If the center of gravity (COG) for the trailer (including payload) is ahead of the axle, then the axle rising will cause a downward force at the hitch attachment to the e-scooter. This is generally desirable, but the hitch and rear wheel must be able to deal with this.
But if the COG is behind the trailer axle, the axle jumping up will cause a lever that tries to raise the hitch into the air. If it’s very forceful, it’ll lift your scooter’s rear wheel up too. This could easily lead to a crash, since all two-wheelers need two points of road contact to be stable. The physics is identical to automobiles pulling trailers improperly, either due to driving too fast or badly loading the trailer.
I don’t want to discourage the idea, but make sure your trailer is properly attached and properly loaded. The reality is that automobiles and trucks are more forgiving because they have lots of mass. But two-wheelers are a lot lighter and need careful attention, since upsetting the wheels will also deprive steering control, which topples all two-wheelers.

I got one of kryptonite’s mounts. I think if I were to angle everything just so I could put on a second mount, but I think I will put a piece of foam over the other tube for the time being.
Nicely done! Does it rattle at all? Or slide down the tub? If this works for you, then congrats!
I rode about 5km today, i think it moved a little. Will adjust it more tomorrow, but it looks fairly sturdy.
I took that picture as soon as I installed it. I have not taken it for a ride yet. I will let you know.
It does have a rubber no slip strip, hopefully that keeps it in place.
I mount my u-lock, and a water bottle holder, which fits my charger instead of a water bottle when I need it to.
