Jeda Wireless
Charging Pad v.2
for our Model 3

I had hoped that Jeda would fulfill my order to upgrade my wireless charging pad from v.1 to the new v.2 before we left on our recent roadtrip to California. However, they let me know that, because of the numerous orders to be filled, my pad wouldn’t arrive until the week we were out-of-town. I put our mail on hold with the post office, and was happy to see that my upgraded pad was among that pile of correspondence when we returned. Below are my impressions of the upgrade and how it compares.

NOTE: You can click on the following photos to enlarge them.

In this photo you can see, from left-to-right, the three different pads that fit the phone compartment in a Model 3: (1) the original Tesla shelf cover; (2) the Jeda pad v.1; and (3) the new Jeda pad v.2. At a glance you can quickly see that the upgraded pad has a smoother surface more like the Tesla cover, rather than the decorative lines and charging circles on the earlier v.1 pad. That minimalist look is actually more functional, because its plainer material produces more surface friction to keep phones from sliding around when cornering hard. The new pad also now has a shelf along the bottom that keeps phones from falling down into the console cabinet when driving over bumps and rough roads.

The differences are even more noticeable on the underside of the three different pads —and I’m not just referring to the v.2 pad’s bright color. If you look closely, you can see that the original Tesla cover boasted knobs that fit into holes in the phone shelf to help keep the unit secure. As I described in my post on the earlier Jeda v.1, I decided to imitate that feature by sticking small, round rubber bumpers in the same location. Now Jeda has also put knobs underneath its v.2 pad, making it as secure as the original Tesla shelf cover. I would like to think that perhaps, maybe, possibly my modification inspired Jeda, but regardless it is a welcome improvement!

I decided to test the charging speed of the v.2 pad using my Amperes app. First I tested the driver side area of the pad...

...which produced these results.

Then I tested the passenger side of the pad...

...which produced slightly slower results.

Finally, I tested the bottom, horizontal position that is a new feature of the v.2 pad...

...and its results were the slowest of all.

In all three tests the pad was connected to the same 12V USB adapter that I had installed in Correcaminos, rather than the USB ports underneath the shelf, one of which I now use for a dashcam thumb drive.

Here are all of the results, from top-to-bottom the most recent (and slowest) to oldest (and fastest), including the test that I conducted months ago with pad v.1.

As you can see, the slowest results were with pad v.2 in the horizontal position, then the passenger side position, then the driver side. The latter test took 80 seconds at 819 mA to charge 1% of my phone’s battery. However, with the v.1 pad, it took only 59 seconds at 1092 mA.

There could be several reasons for these differences. Perhaps, like in a Tesla, charging slows down as the phone battery fills up, and from top-to-bottom the percentage of charge was higher when I started the tests. Or maybe the difference between the v.1 and v.2 tests is because I had four apps running on my phone this time: besides Amperes, the Tesla app, and my music, the calendar was also active to synch with Correcaminos. Another possibility is that the new pad distributes more power from the 12V outlet to the driver side than the other positions because it now has to share the electricity among three wireless charging areas, rather than only two. And maybe the v.2 material is simply denser, and is thus dampening slightly the wireless signal.

All this is speculation, of course, and to tell you the truth the slower v.2 charging speeds above don’t bother me. The speed on the driver side from the 12V adapter is still faster than charging from Correcaminos’ dedicated USB ports with pad v.1. That test took 119 seconds at 546 mA, i.e., about the same as the v.2 pad on the passenger side from the 12V outlet. I can live with that, especially since the updated pad boasts a more adhesive surface and a bottom shelf which help keep phones from sliding around and falling down when on the road. It’s a winner!


Out of curiosity, a few days later I decided to run some more tests, first plugging the driver side into the 12V outlet and the passenger side into a USB port; then plugging both sides back into the 12V outlet. Here are the results, in reverse chronological order:

As you can see, that order produced faster and faster charge times. I can only conclude that such a wild-and-crazy variation has nothing to do with the ports or the Jeda Pad: the Amperes app is simply bonkers.
