    Default USB Tolerance

    Can somebody explain this to me? I'm kinda confused about what power bank should I buy. One says the output is 5.3V 2,000mAh(Charger A) the other one is 5.0V 2,100mAh(Charger B). I will use it on my Samsung Galaxy S4 which has a charger that outputs 5.0V 2,000mAh.

    So which one will i buy, i'm confused because samsung charger is 5.0V charger A is 5.3V so that's exceeding. However, charger B is 2,100mAh when the samsung charger is only 2,000mAh which is also exceeding. So will both this powerbank do some damage to my phone because it does not output the same as the charger of my Galaxy S4?

    No doubt you will get a technical reply but I can't think of any reason at all, except emergencies, for using a charger which differs in specification from what the manufacturer recommends.

    Ah, I see. I wish you every success. My instinct would be Charger B as less likely to do damage but let's hope for a post from a member with knowledge of such matters.

    Consider: charger A is 6% excessive in voltage pressure; charger B is 5% excessive in mAh rating.

    i read through some articles, what i've read is that the phone will only take the amps that it needs so it doesn't matter if you plug a higher amp charger. Is this true?

    I've heard the same thing, but I'm afraid I don't have the knowledge to say definitely whether it's true. Of the two options that's the one I'd choose.

    And that would be charger B?

    If I had to choose one or the other, yes, I'd choose B.
