Solar trickle charger

[JonGreen]

Hi all, my car is going to be left for a few weeks in a car park and I was wondering if anybody had any experience of the solar trickle chargers that plug directly into the OBDII port?

I'm thinking of something like this.

You probably don't need one for a few weeks unless, you're one of the unlucky owners who always have some drain (which i do).

I've not used one on the F type, but have one which I use to keep an HGV car transporter charged when not in use. Panel sits on the dash and plugs directly into the OBD. The vehicle only gets run one every month or so and it keeps a constant charge of 12.6v
Been very happy with it for the 6 months it's been plugged in use, no OBD issues, codes, etc. and starts perfectly.
I opted for the 20w as my research indicated too small a panel doesn't work well on large batteries or when not in full sun.

20w version plus OBD connector is what I opted for:

Edit
Just checked the link to the AA version and it's peak is 4.8 watts in full sun

if you have had issues with battery just get a new one and all will be fine, mine can stand for 3 months no problem, new battery last year

Mine stood unused for three months during lockdown and started on the button after that time, albeit with a low battery warning.
