Also happening to me, though I haven't contacted them yet. It still works if I play with it for a minute or get lucky and hold it in the right spot and let go gently it'll keep charging. If I jossle it out of place it will throw the 4 lights error and stop charging.
About 4 weeks ago this happens to my TB. Insert charger, lights act as though it’s about to charge, get a flash of all 4 lights then dead.
I sent a video to Tafee and they sent me a label to send back my puck.
After about 4-5 days I had a tracking number for a replacement base puck, and Customer service sent me this email:
1. Try to allow the battery cells to stabilize over a few minutes before connecting it to the charger to recharge after a heavy or demanding session.
2. Take time to note the correct orientation of the Micro USB and the charging Port before attempting to insert.
3. Slide the Micro USB cable into the Port carefully at exactly a 90-degree angle and use both your thumb and index finger to guide and soften the connection.
4. Similarly, always use your thumb and index finger to soften the separation of your charging cable from the Puck Base Unit with the other hand securely holding the puck steady or on a flat surface when disconnecting from charging.
5. Under no circumstance should the charging cord ever be wiggled into the port. Wiggling the charging cord into the port can cause impactful damage around the area and cause your unit to cease charging sufficiently.
Apparently I had damaged the USB port, though I rarely unplug my puck..
Anyway, new puck arrived yesterday along with a potter, 4 pots, stir tool and mouthpieces.
I know this device gets some hate from people, but this was the easiest warranty return I have ever been a part of, they sent me some nice little additions along with a brand new unit.
I almost forgot how delicious and effortless the vapor production is with the TB, almost…
