Here is a picture of the stand that is on the main page of their Store section. It appears to have something that lines up with those metal tabs.I have no idea what they are for but it does indeed have two metal contact plates on the bottom. Hopefully you’re right about a possible future charging stand/station
I’ve done a fair bit of stalking on their page because I’ve seen mention of the self recall function but can’t find documentation. It also doesn’t make sense that they would sell both the N1 and the S1 on their website, but with a $100 difference. I don’t know, there’s just a couple of weird things.
But, I ordered the S1 Pro with the coupon to try it. At $760 it seemed like it was worth a try and I could send back if it didn’t work like advertised.
