This went down nicley with muh coffee! Great demonstration and elaboration of elements and their pertinence of the board. Solid confidence and resonates for all consumers to make informed purchasing decisions. :) Thanks for doing these in total. *Subs, likes*

That giant electrolytic capacitor in the center is waiting to swell and leak!

Kenapa pabrik memilih 350v dan bukan 400/450v ?

[@FreeSeed]

Thank you for the video

[@venkatanageshbabuchintapal1618]

Please make a teardown video on Toocki 67Watt GaN charger and Essager 67Watt GaN charger. Thankyou

Can you do a teardown of the Asometech 160W GaN Charger?

[@FIxt00l]

Thanks! Kovol and Evatronic look identical to Ravpower. Do you have any info on that, please? Evatronic was being sold on their website.

[@sjoerd104]

Yep evateonic is ravpower, they had to change names because they weren't allowed to sell on Amazon (idk why)

A lot of brands were found to be gaming Amazon's review system so they were banned. Somehow Anker was not part of the ban and they were left to corner the market. Now that they have a captive market their quality has gone down. It's a perfect time for competitors to steal their thunder.
Alas, a lot of these less expensive brands have no safety listings. Notice that there is no UL, ETL, TUV, SGS, nor PSE diamond mark on the charger in the video. The UKCA and CE marks are self-declarations of safety and are worthless.
