ADVISORY: Avoid using the Efest SODA charger at its 1A setting

[unable to retrieve full-text content]

I have seen a couple of mentions of overheating and failure with Efest SODA chargers so I decided to check into it.

View attachment 664119

I measured the external and internal temperatures of two SODA chargers at their 0.5A and 1A settings, charging two batteries at once. They were only about 3°C apart for any temperature reading so I averaged the two readings.

Ambient temperature = 27°C

Temperatures at 1A:
Top external = 71°C
Bottom external = 87°C
Internal = 108°C
Batteries = 53°C...
