### Problem:

Customer reported a Mini Puck drawing higher-than-expected current and heating to about 55°C. Current rose from 150 mA, briefly reached 700 mA, then stabilized around 350 mA at 14 V.

### Answer:

Likely hardware/QA issue with the original Mini Puck unit. Replacement resolved the problem.

55°C was considered normal, but the current draw was higher than expected. At 14 V, 350 mA is about 4.9 W, which we considered slightly high; 700 mA is about 9.8 W, far above expected.

A replacement Mini Puck was sent. The replacement drew only 140 mA at 14 V, while the original drew 310 mA at 14 V with no Ethernet connected. The replacement also did not heat up like the original.
