GH5 Which of these dual battery chargers is better?

Hi, I have just bought GH5 and I will need to charge at the same time. I have seen these two charge batteries:

In your opinion which is better between them? In don't understand well if the yellow charger can discharge also the battery before to charge it.
Thanks for your info.

I have one which is also made my Patona (so the brand is good):

Its perfect for travel, where I have 3 batteries and doesn't require any additional leads as it uses my current 2.1A USB charger.
