Power Function Converter Cable for LEGO MINDSTORMS This is a follow up to this question:
How to use Power Functions with Mindstorms EV3?

The question was asked in 2013 (5 years ago). Fast forward to 2018, the product that was suggested in the answer is retired:

Is there a replacement for the retired product?

Is there any better option, other than what is shown in this video?

No, there is no replacement yet except soldering your own cable or using third party products. Basically the answers in that question of 5 years ago are all still valid. 
Mind that LEGO is transitioning to a new power functions system (with motors and sensors as in the boost and WeDo 2.0 products), perhaps we'll see solutions for that quite soon.
