Portable AC not getting ride of condensate
In cool or dehumidifier mode if you don’t have a pump you will have to dump the condensate based on your humidity, it is a basic function of cooling that there will be moisture to get rid of. 
Don’t believe me put a glass full of ice water on a table with enough ice to last 15 minutes, now look at the ring of water at the base of the glass. If you want the system to cool there WILL be water to get rid of times a hundred or even 10 thousand depending on the size or amount of cooling and humidity. In a high humidity zone the amount of condensate or water you need to get rid of can be the same. It is normal and expected with cooling or dehumidification.
