Pictures, or it didn't happen!
No pictures unfortunately. Install was super easy, took maybe 5 minutes at most. The unit is nicely packaged in a sturdy black box that says "Nomad", I re-purposed the packaging to store the original Model 3 mat and cables.
I intentionally let my iPhone run down last night and then used the Nomad on my drive into work this morning. On my 25 minute drive my iPhone X went from about 50% charge to about 70% charge which is pretty good I'd say! The phone and charger were a little warm but nothing alarming. Nomad has built a lot of iPhone accessories so I have to trust them that they've done good level of testing on the batteries they are using.
As others mentioned the new charging base is thicker than the factory Tesla one, but there's still enough room to close the lid. Having the phone a centimeter or two higher up isn't bad since you can reach in and get it more easily. The Nomad is really grippy and on my drive it didn't move even a tiny bit even when I threw the car around a couple of corners to really try to shake it loose.
The charging lamps are nice too, they glow amber/orange when charging and go green if the phone is fully charged.
This is the solution that Tesla should have put into the Model 3 out of the gate, no question. I expect a refresh to the Model 3 that puts something similar in.
I don't have any experience with other charging solutions but it's hard to see how anyone could do it better than these Nomad guys are doing it... I would be especially leery of anyone who is doing this as their first rodeo.... Lithium Ion batteries need to be really tested thoroughly especially at higher temps for automotive use.
