Teardown Anker's Latest Wall Charger and Found This. What's This? 

Heat transfer compound is a 2 component mix, that is poured in at final assembly, to fill all the voids. Stays flexible and somewhat sticky, as it will slowly flow with heat to help ensure all the voids are filled. Similar to the thick thermal pads used in equipment, in that it ensures better heat transfer from hot areas to the case, though it is not as good as a proper aluminium heatsink, but as it is cheap, insulating, and also helps with minimising creepage on the board, it is used.

Guess you need to tell us 5 more times why they used the silicon.

The Apple 5W USB iPhone charger cube has used an active clamp circuit for more than a decade. GaaN is the major innovation in these Anker units.

This is the nightmare of new disposable electronics 🤮

Very poor, anti repair design. It's better to use simple finned heat sinks.

I didn't expect your understanding of electronic products to be so shallow. The first cover you pry off is to cover the thermal paste filling hole. The reason for the heat generation is because power and efficiency have little to do with space. This is done simply because a 65W charger will have a thermal power consumption of up to 7.2W even if the conversion rate is as high as 90%. What's more, the high frequency of GaN chargers will reduce the conversion rate.

Pink, highly heat conductive materials always make me wary - could there be beryllium compounds in the mixture, which can be extremely toxic to breathe?

Why on earth would youtube keep recommending this to me? Do they owe the uploader money or something?

That pink stuff looks like it came off a lot easier than whatever was all over the board in a laptop power supply that I recently tried to clean.

Great teardown. That strange silicone seems an acceptable means of transferring heat, since heat transferred to the opposite side of the charger when desoldering the PCBs. Any solution is better than no solution in my mind.

Comprehensive video, very interesting and informative, thank you!

Wow, some in-depth knowledge gained 😮❤

I wonder if they pull a vacuum to help fill these with that pink stuff.

How many farad long capacitor?

Do you have another channel? Didn’t you make a battery welder?

Howw are you doing the translation?? This is so cool

Tonight I am sure I will have dreams about pink silicone.

Is it just me or is there something playing in the background (someone else's voice)... great info and breakdown...

I wonder why it is filled with silicone
