Has anyone used a Tesla Mobile Charger for their MG4?

I noticed Tesla do this charger for £180 and also offer an adapter for £40 that lets it charge at 32a, has anyone tried with or even just used this charger as is?

A few comments that may be useful, but I can't guarantee it

Whilst I haven't used the Tesla "mobile connector" I do have the Tesla Wall Connector and I have a Chinese "mobile connector" equivalent (but it's smarter and more on that later).

The smarts on the wall unit are controlled via the Tesla app. It's the same app that you need to use "open" Tesla chargers and indeed the same app that you use to manager a Tesla Powerwall if you have one of them.

The app lets you configure a "power schedule" which you align with your electricity provider. In our case in Australia it is common to have different costs associated with different times of the day, which are commonly called, "peak", "shoulder" and "off peak".

In my case I have my charger set to charge between 9PM 'til 3PM the next day and not charge during our "peak" rate between 3PM and 9PM.

When I plug the charger into the MG it will charge during the "cheap" times and stop charging during the peak. The car will happily wait until the charger resumes charging if it hasn't reached its charge limit before stopping and then restarting the charge session when the peak time passes.

You don't have to program the car to do anything special (except you may set whatever upper limit you want it to get to, and that's a set and forget thing). I set this at the 80% recommendation for NMC batteries and occasionally change to 100% if I'm going on a holiday trip around the country.

The wall connector can be managed by the Tesla app as it is Wi-Fi connected and manageable.

From what I can see reading the manual for the "mobile connector" it is not Wi-Fi enabled and cannot be managed by the Tesla app. In essence, if it is plugged in to a power point it will start charging and keep on 'til the car says to stop.

My Chinese portable charger lets me set a delay for when to start so that I can potentially get it to start when the power is better priced and also I can set the current it draws. It has a 15A plug as well as the standard 10A plug we typically use here in Australia. I have had a dedicated 15A circuit installed in our holiday house so I can swap the charger from 10A to 15A easily when there and also set the delay appropriately as required.

To my mind, if you're going to the trouble of putting in a dedicated higher power supply (such as 32A single and/or 16A three phase) I'd get the proper Tesla Wall charger as well.

It makes no sense to me to get a completely dumb charger if going to the expense of installing the good stuff powerwise.

I'd keep your cheap and cheerful Chinese unit for travelling and get the proper charger for home.

Looking through the manual it is very basic, relying on the word TESLA lighting up in green or red and a series of up to 7 flashes, or pulsing of the light to indicate status, so unless its printed on the back of the unit you'll need to keep the manual handy to work out any errors.
It has the advantage of UK 13A adaptor and 16 or 32A CEE connector (at cost) but its price reflects the name on it. If you need to monitor the stats for the charge then you'll need a plug through power meter which is not ideal. I'm sure there are alternatives that offer a lot more for the price, like a display for instance. The Third Rock charger we've talked about before has the display and the 16 or 32A connector but misses out on the interchangeable 13A plug adaptor.

I plan to use it as a 10a wall charger and as a 32a through the cee connection so the price is very cheap for me. I was just worried the Tesla one wouldn't be compatible with MG but if the wall mounted ones are I imagine the mobile one is too. Thanks
