Should We Buy It? | Teardown of "Fake" HP 65W Power Adapter

[@PedroDaGr8]

It would be good to teardown the main transformer. It is very common for cheap knockoffs to not properly insate between the primary and secondary and to not obey creepage distances between the ends of the primary and secondary where they go into the PCB.

The transformer looks to be of good quality though

Should i purchase this charger in 2024 for my Hp Elitebook X360 1030 G4

wait... chargerlab I just thought of something. What would happen if you use a usb c to lightning charging PD adapter like the one by Meenova on amazon and the Nintendo switch to charge iPhone? Since the iPhone 14 Pro Max pulls 14.5v 2a 29w by selecting the second PD option, most PD chargers cannot reach the max power because the iPhone pulls 9v 3a and is limited to 27w as a result. However, it seems that the iPhone can go even higher. What would happen if the nintendo switch charger was connected with an adapter from usb c to lightning PD and then connected to iPhone 14 Pro and Pro max? Since the Nintendo switch's second PDO is 15 volts at 2.6 amps with no 9 volts supply, would it just pull that power or would it drop back to 5 volts? I'm hoping that charger can charge the iphone pro max even faster than the 29w charger and reach 60+% in 30 minutes.

That OnSemi 1342 looks like a non-genuine knockoff, as does the EL1019. That is probably one way they reduce cost is using knockoff chips.

How can you say that it's actually fake? Does it have something to do with the product number?
