Pesky USB Ports - what would happen if I put Noalox in a USB port?

    I'm wondering if Noalox would ruin a USB port since it's 20% conductive Zinc dust?

    I have USB ports that need to conduct their full milliamps but due to age and possible small amounts of corrosion don;t do a good job.

    If not Noalox, what can you do to improve a USB ports conductivity?

    A quick call to Ideal (Noalox manufacturer) revealed that it should NOT be used on USB connections.

    However, I found THIS at NO-OX-ID (sanchem.com)

    Do NOT put conductive material into a USB port! Even contact-cleaning solvents could be risky, unless you know for sure that they won't affect plastic parts.
    Very light abrasion may help, but you risk removing any anti-oxidation plating on the contacts.

    Sounds like failure by design right from the start..

    If you mean Micro USB ports.....I agree.
    They've been trouble on cell phones since day one for many people.

    2nd ONLY to cracked screen glass in cell phone failures

    I mean that if you are doing something that expects 100% performance out of anything and will not accept anything lower then you have set yourself up for instant failure..
    The phone or the port or glass is not the problem.. Humans are..
    The glass doesn't break itself.. The ports don't break themselves..
    I have never had a problem with a micro USB port..
    But I'm aware of its limitations and am gentle and respectful of it..

    I heard a suggestion that you would have to have a licence if you wanted to have a baby. To get the licence you would have to bring along your phone and if it had a cracked screen you would be refused ;)

    Sounds like a reasonable step..
    In certain states in the US they have banned drinks over 20oz or something like that.. We don't even trust people to make healthy decisions so we need to pass laws like that..
    sad..

    Ok, I think you're saying the device (in this case a Thermal Imaging Camera) is demanding too much current for the phones USB port to deliver...or that it may be demanding near the limit of what it can deliver. Is that correct?

    I'll have to check into that. Right now I don't know what the current demands are for the Thermal Imaging device nor the rated specs on the Phones USB port. The phones USB port I'm pretty sure MUST meet standards set forth by International Communities that set such standards.

    I do know that a large number of these devices have been sold and I don't see that as a common problem so maybe it's just my phone.
    The one I'm using to be honest is an older one.

    Also, I'm not sure if the issue is the battery or the USB circuit of the phone (or the devices demands). I'd need to load test the battery.

    Is there a way to measure the current carrying capacity of a particular phones USB port?
