How to mount an external cable

I bought this 10 meter cable to charge the battery in my scooter outside.

I would like to know how other people have mounted such a cable on their vehicle.

I'm thinking about mounting it on the front of the scooter so i have quick access to the plug while i sit on the scooter and might even be able to connect the plug in a socket without getting of the scooter.

Have also been thinking about wrapping the cable around the seat area.

I think the more easy it is to use the more i would like to use it. So i'm thinking i would like something that is easy and fast to use. Not having to stand up, unlock the seat etc.

Velcro or maybe something like this:

I dont really remeber seeing anyone having a 10 meter long cable on an electric vehicle.
Am i the only one seening that as useful?

Sure if the socket is in the ideal place etc. then you only need a short cable but at least where i live there have just about been done nothing at all to make these sockets for public use.
 
I have a power-cord reel from an old vacuum cleaner that I intend to use as a charging cord on my trike eventually, once I get around to installing it. It's only two-wire, so no ground, but it is sufficient gauge to handle the current, as it was from a "12.0 Amp" vaccum, and my charger doesn't draw anywhere near that much current from the wall (though it does provide that much to the battery on the DC side). I'll just be wiring the reel's cord direct to my charger's input, rather than using a socket for the charger to plug into, then leaving the two-wire plug on the wall end of the reel's cord.

Some examples

though mine is different from all of them in various ways.
 
I have been thinking about the same with such a powercord reel from a vacuumcleaner.
But the problem i see is that part of it is not protected.
The spinning part and static part most have som metal sliders and unprotected connectors.
I don't think that will be good to use outside.
Even if it is protected against rain it will get moisture inside it.

Not sure if there are any of them where the cable go all the way through.
But please show me if you find something good for outside use.

I have tried something like this for a computer mouse where you pull the connector and the box stays in the middle of the cable.
I think that way you can put it on any cable without modifiing the cable.
But then if i have 10 meter cable and only need to pull out 2 meter the box with most of the cable needs to go on the ground which i dont like.

There's this type, if you can afford them and you don't mind the relatively gigantic size

It's very dry here most of the time except during the infrequent rains (which can be flash floods!) so for my purposes it is unlikely to be an issue with the salvaged vacuumcleaner reel. However, for anywhere that does have significant humidity, rain, etc., you might need to oil the metal parts of the reel inside to prevent moisture attacking it.

There should be no electrical connectors inside it--on mine all the connections are done outside it either at the AC plug to the wall when plugged in, or at the charger itself in my case, or the charger cord in yours if you're not directly wiring the reel to the charger, but just using the reel as an extension cord. In the latter case, you'd simply do whatever waterproofing you can to that connection, which you would have to do with any other kind of extension cord, anyway. If your reel did for some reason have internal electrical connections, you could waterproof those similarly, unless they are the type that are sliding electrical contacts along a ring. For those, the best you could do is coat (or pack) the area with dielectric grease and periodically check it.


EDIT: I am wrong about the one I have--it does also use the sliding contacts on a ring...but it already has dielectric grease in the area, and it is covered with a dust-jacket so it could be kept re-packed with grease as needed.

But in my case it would be inside the cargo-seatbox with the battery, not outside the trike, so it wouldn't be exposed to water at any time anyway, unless the trike was flooded to the point it got on the battery anyway, in which case I'd have worse things to worry about. ;) :bolt: :flame:

are very similar to what I have; the reel is black on mine, and the red wire shown there is black on mine, but the rest appears the same. I can't see the back of theirs; mine is a metal plate covering the spring assembly.

In either case, the reel I have has been quite durable; the vacuum it came from was at least 40 years old and served us well (the hose disintegrated and was repaired, the motor brushes replaced once, eventually something happened that took out the motor but I no longer remember what it was; I saved the reel and the heavy-duty footswitches when recycling the rest of it).

The problem with all of those types that I've ever opened up is that in the center of the reel, there is a very sharp fold of the cable. Most wires are not designed for that kind of stress on their insulation, and over time the plastic may "retreat" from the high-stress area, thinning the insulation and potentially even parting entirely, if the environmental temperatures ever get high enough to soften the plastic that much (or if the temperature swings are enough to eventually cause thermal cracking of the stressed plastic insulation). It's not *as bad* with a flat cable like that shown, but if using a round cable there will be a lot of tension stress on the part that is on the outside of the bend, and compression stress on the inside--more the larger the overall diameter, and the tighter the total bend is.
 
Something like that weatherproof thing might be nice.
Guess it might be like the reel from the vacuum cleaner just with a weatherproof box around it.

Of course i would like everything to be light too but i guess 5 kg would be acceptable.
My 10 meter cable weighs 1,7 kg.

I have just installed a front carrier on my scooter and a temporary basket.

I want to have something like a water hose holder to hold the cable at the top and be able to lock it in place.

Found this funny one.
