• Could a "magsafe" wireless charger get full spec output with a 5W usb b

    From Andy Burnelli@21:1/5 to nospam on Sun Jan 22 21:07:13 2023
    In a post just now, nospam said that it would, but I find that hard to
    believe on wattage requirements alone - but maybe nospam is correct?

    I openly admit I know nothing about magsafe chargers.

    So I defer to the audience on the iPhone newsgroup who know more than I
    about whether or not nospam is correct a 5W brick adequately powers magsafe chargers.

    The message that prompted this question is included, verbatim, below.

    no it isn't. magsafe is ~15w, for example.

    Hi nospam,

    You're probably correct.

    I'll openly and publicly easily admit I know absolutely nothing about
    magsafe chargers (and yes, I know with your low IQ you'll have a field day
    with that open honest admission - which is how I know you have a low IQ).

    Since I know nothing about magsafe, I'll defer to your judgment on how fast magsafe is on a typical late model iPhone - but _my_ experience with the Qi that Steve recommended is that it's super slow (convenient... but slow).

    Just like badgolferman said it was.

    And in addition to that...
    *Wireless charging effectively permanently eats up one USB-C wall
    charger*

    nope. a wireless charging pad could use usb-a, usb-c, or be directly connected to mains power or vehicle power. there are also battery packs
    that connect wirelessly.

    Whether or not a 5W USB-A will power any given wireless charger remains to
    be seen, where Steve might have something to say about your claim, nospam.

    And while any given wireless charger _can_ be designed to be powered
    directly from the mains or via 12VDC, most Qi chargers (in fact, all)
    I've seen (at any decent price anyway), are delivered with USB-C cables.

    But the point remains the same that the wireless charger at least "often"
    eats up one of your charging bricks - and it's "often" a USB-C brick.

    My main point was nobody is going to share chargers, period.
    With any device.

    Only you iKooks recommend that BMW sell an expensive car, not only without wheels & tires, but that BMW tells you to use your old tires, even as BMW changed the lug hole arrangement on the wheels (to add glue to the trap).

    But to your point, I'll defer to Steve & to badgolferman as to whether a Qi
    or magsafe charger should be powered by a 5W USB-A brick as you claimed.

    I'm an adult

    many vehemently disagree.

    The way I know you own the brain of a kindergarten kid, nospam, is you take
    all bait (like a dumb mouse with cheese in the trap), fully as expected.

    Your "wit" is that of a child, unfortunately.
    It reveals much about you (as your many 'ftfy' excuses reveal about you).

    You have no _adult_ thought processes, nospam.


    so I commend Steve for what he does well, which is

    trolling.

    It's no longer shocking that you iKooks can't comprehend that I commend
    anyone (Steve or you included - hell - even Alan Baker or Snit!) if they
    say something commendable - just as I criticize them when they do not.

    My assessment of Steve is he's a wannabe in two very important ways:
    a. He's a wannabe Verizon-high-end customer, and,
    b. He's a wannabe Apple iPhone high-end customer.

    In addition, you are fully correct in your assessment of Steve that...
    c. He wants to come across as an expert (as do you, nospam)

    This works to our advantage in some ways, because Steve is effectively a low-end schemer trying to get a high-end product with his many schemes.

    It works to my advantage, as I'm a low to middle end customer who doesn't
    want to go through all the hassles that Steve does to _find_ a good price.

    So when Steve pointed to a good almost free Moto G(7) for free from Google,
    I took him up on that offer, and I benefited from Steve's information.

    Likewise, when Steve pointed to a set of three inexpensive PD & QC USB-C
    and USB-A chargers, I picked up a pack and gave them as stocking stuffers.

    Similarly, when Steve pointed to the one-day-only Amazon-Prime sale on $9
    USB-C + USB-C + USB-A 67 Watt chargers, I took him up on that also.

    In keeping with following Steve's advice, I picked up two of those Qi
    chargers Steve recommended, and that's when I learned they come with USB-C
    to USB-C cables (I had expected them to come with USB-A to USB-C instead).

    I even picked up an HDMI/USB/SD hub that Steve recommended to help someone
    with a high end HDMI-able Samsung to move his data off the memory storage.

    Given how much of Steve's advice I've taken in just the past few months, I would be remiss in not thanking Steve for his wonderful acumen in such
    things.

    You don't understand any of this balance that I have, nospam.
    It's one of the indicators of how I know you own the brain of a child.

    which, in this case, is to respond to nospam's claims which require proof.

    Why should anyone care if a cube charger released more than a decade ago
    can or cannot be used with a much more modern piece of kit?

    Not sure since I have those trolls filtered out, but I suspect that
    "nospam" is insisting that no one needs to buy a new charger when they
    buy a new iPhone that doesn't come with a charger because their old 5W
    charger will still work, while "Andy" is insisting that a new charger is necessary because MagSafe needs at least a 12W power adapter, and 20W is recommended <https://support.apple.com/en-us/HT211829>.

    While you can certainly get by with an old 5W power adapter, on a newer
    iPhone, for wired charging, it isn't a great idea for multiple reasons.
