    Your entire argument was “Ah is useless and Wh gives consumers the information to determine battery life” So go ahead, determine the battery life.

    Not quit sure where battery life is comming from, thats not my argument. To restate and also better phrase my argument: Stored energy is the better measure for consumers for the quantification of the battery size in a consumer device compared to Ah stored charge.

    Now i can cross compare devices based on that and do not have to worry about the Voltage of the battery of any other devices.

    Please state the calculation that you would use to “determine how often you have to recharge” that is valid for Wh and not for Ah.

    I never claimed that this is possible. I wrote “can recharge” not 'have to". I am referring to devices like a power bank which i can calculate with a simple:

    powerbank has 100Wh and phone has 25Wh so 100/25=4 -> i can recharge my phone 4 times using that powerbank.

    I am ONLY speaking from a consumer position and for those Wh is more useful.

    The consumer looks on device a and on device b and then determines how often he can recharge its device. With Ah you cannot do this unless you know the Voltage, with Wh you can make this decision without any further knowledge.

    Yes this does not include battery life or conversion of efficiency. But a cunsumer measures nothing he looks at the lable.

    It is fine if you don’t understand electronics, but then don’t spit out misinformation.

    Btw. no need to insult me. I have never put out misinformation, I may have not stated enough that I am viewing this as a consumer.






  • While i am personally also not a huge fan of TPM for FDE it is still a valid use. Why? In order to access data on the disk you would still need to bypass the login screen which is non trivial. Also another use case is encrypting the drive so when you sell it or dispose of it you do not need to worry about wiping it at least once to get rid of all data.

    TPM has its weaknesses but pls don’t talk down to someone who wants to use it when you do not understand his use case.




  • The problem is that you cannot be sure if it follows spec. You as a normal user can only verify that it works on the current gear you have. What if the output signal strength is on the higher side of the spec on the current gear and you buy a new (for example) graphics card which has a lower output strength (but still in spec). And the cable no longer works?

    HDMI and DP are especially frustrating. Had enough problems with cables that ‘worked at home’ but no longer on a different setup in the past.
