Battery Charger/ Solar battery maintainer?

Does anyone use a maintainer that can be powered with solar panel in the car? I'm not blessed with a garage or external sockets hence this approach.

Does the RRS cigarette lighter disconnect when power is off, would OBD connection approach work better?

Was thinking something like this? (note the OBD cable in accessories options)

Any alternatives welcome as I could hook up a CTEK* with extension but would be through front door i.e. not ideal and only be able to do that once a week etc.

*I presume this CTEK would be sufficient? (aware cheaper from Amazon just checking this would do the trick)

If you don't have mains power, I would get a large solar panel with the OBD connector off ebay.

I bought the AA one with OBD connector about a year ago and I'm really pleased I did.
My car is only used about once a week (if that) and since I've been using the AA solar charger the car starts immediately, no delay and the battery has remained at full capacity through the trickle charge system.
Only thing you need to remember is to remove the OBD plug before turning the ignition or you can cause damage to the ECU'S (apparently). 2016 RRS SVR Estoril Blue

If we all point our RR's in the same direction and accelerate at the same time can we turn back time?

Do you lock your car down in access mode as well? I believe from my wanderings around here that this also helps minimises power use- although happy to be corrected if my skim reading is wrong Thumbs Up 2008 TDV8 Buckingham Blue- SOLD

Never needed to put it in access mode as the solar charger keeps the battery at full capacity. I believe that’s to shut down the ECU’s rather than leave them in standby if car is going to be idle for a long period of time. 2016 RRS SVR Estoril Blue

If you keep your car garaged in a garage that has no power supply it is now possible to get outside mounted small solar panels with long enough leads to get inside the garage.
The thing with putting it in access mode is to do with sleep mode for the ECUs, basically if you lower the car and lock it the system will automatically go into sleep mode after 10 minutes IIRC. If you don’t then the security system keeps the car in a sort of standby mode, alert all the time for your key fob. It will consume power all the time staying ready to go - a bit like putting your TV/ computer etc into standby rather than switching it off completely.
With my PHEV I still connect up my solar panel to keep the 12v battery for the Petrol engine to keep that fully charged as it doesn’t draw power from the electric motor battery to keep it charged - with the big battery I can leave it plugged into a 13 amp socket for up to 4 months with the charging set to lowest rate and on the off peak charge timer - it will also self heat the battery if it gets very cold outside but only if the car is plugged into the mains. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Too late bought a CTEK via Amazon as needed it speedy as car didn't want to play Big Cry . I've topped up the water, was tiny bit low, and ran a CTEK recondition mode over night (after taking the battery out....Jeeeebus it's heavy!!!)

Just put back in and all seems tickety boo, and started first twist no problem, gave it 10 mins or so running as to give the engine a gentle warm through (short on time otherwise I'd have taken it for a proper run), lets see if it starts tomorrow (locked down in access mode...every little helps Whistle ).

The AA solar panel thingy is due to arrive Saturday to keep it topped up.

Thanks all for help / feedback etc Thumbs Up will report back 2008 TDV8 Buckingham Blue- SOLD

From what I have read about the Lidl charger there is only a problem if there is a power cut. It does not restart, you have to switch it back on. How many power cuts do you get? To be honest I dont know if my Ctek restarts automatically in these circumstances. Anyway if I had a power cut I am sure I would check any live sockets. For 14 quid its a no brainer if I did not already have a battery conditioner.
