Ember Mug Charging Base Pogo Pins Replacement

Description: The spring contacts, AKA pogo pins, are a...

Steps:

1. The charging base has two spring contacts, also called pogo pins, that transfer power from the charging base to the mug.
2. Over time or due to liquid exposure, the contacts can oxidize or lose their ability to spring back up, resulting in a loss of contact and thus failure to charge the mug.

3. The rubber base on the bottom of the charging plate covers a Torx screw that must be removed to open up the plate.
4. Peel back the base far enough to expose the Torx screw.
5. Using a T8 Torx driver, remove the single retaining screw.

6. Use a metal pry tool such as the iSesamo inserted into the seam between the metal top and the plastic base to open it up.

7. Here we see the two halves separated, but connected by wiring.
8. The circuit board is held on with adhesive. Use your pry tool to gently separate the circuit board from the plastic mounting block it sits on.
9. During reassembly, make sure the cutout in the plastic base sits correctly over the circuit board.

10. Here you can see a closeup of the pin with the failed spring on the right vs. the functional pin on the left
11. The pins are approximately 4.5 mm in height on this particular model.
12. Here is the replacement pin placed next to the originals. So far, so good.

13. Apply flux and unsolder the defective pin or pins.

14. Tin the replacement pin.

15. Using the minimum amount of solder, solder the new pin in place.

16. The adhesive keeps the parts together, but also provides a modicum of waterproofing.
17. I chose iPhone battery adhesive as it appears to be very similar to the original adhesive found on the charging plate.

18. Stick the circuit board onto the black plastic mounting pad.

19. Reassembled with the new pin in place.

20. Final step, place the mug on the charging base.
21. Success, we have a charging light once again!
