I have tried an old Samsung phone charger - the same "issue."Looks like a good charger, would be nice if manufactures include the right spec $$%% charger for the device they are selling at these price points.
Do you have a phone charger you could try when it needs charging next time to see if there is any difference in heat? We can rule out the Baseus charger if the same overheating happens with a 10w-25w phone charger.
The ca1000 becomes pretty hot in around 20 minutes after connecting.
