I can’t remember the last time I used my car, but when I do... heat added

I love me some pre-emptive heat

By 75p, but I'd imagine people would rather pay the "extra" from amazon.
These look good and work great, comes with the DC power adapter. The motorised side arms are clever and will make your car go faster like stripes on the side on the car, red brake assemblies and air fresheners!.

Be aware, Wireless chargers in windscreens work well but are VERY susceptible to heat. On a warmish day (+18 lets say) they turn themselves off to avoid over-heating

That's a very good point, although this one does have a cooling fan built in.

Id be interested to hear people's experience with this one in that case! Mine is a pig for turning off (LED goes from blue to green) when it gets warm (and its notably quite hot to the touch cause of the glass greenhouse effect!)
This is the unit I have: amazon.co.uk/gp/…F2/

I have this one and it's very well behaved

Does it support Fast Charge (QC 2/3.0)?

It comes with a charger.

Given the voltage support it appears to be PD and not QC.

However I haven't put on a analyser tool but it's an educated guess.

looks like it supports Fast Charging on S10+ (which is what I have) - might have to give this a shot. Only thing Im unsure on now is the screen mount, looks a bit on the small side - is yours windscreen or vent mounted?

Mines vent mounted but I wouldn't worry, the adhesive they use seems to be a bit proper!.

That's why I went vent mounted as I'm undecided on how long I'm keeping my car and this thing doesn't look like it's going anywhere once mounted!.

As for the wattages, from my understanding it's just the coils and regulator system used that determines the current it's willing to accept from a charger.
This will output 20w, whatever your device will accept will be the limit.

So it's not a protocol, merely the same field, but more powerful.
is it ok to leave these plugged in all the time? risk of draining battery?

You would need to measure the current draw for that. And I don't think anyone will normally do that. As you also need to include the 12v chargers inefficiencies.

That's a very specific use case.

How are you planning to use it?

I thought it would be reasonable to have it plugged into cigarette charger all the time so that it's ready to go as soon as you get in the car?

That sounds normal, so it's only powered when the cars in ignition?.
In that case nothing to worry about.

My car still powers the cigarette lighter even when I turn it off and lock it. Not sure if that's normal or maybe it cuts out after a while. Haven't checked yet.

Oh ok.. my old ford focus used to do that, I used to have my chargers connected all the time, and it was fine.
