Does anyone know where I'd be able to get a replacement charger for the 640? I've got the US version but I live in France and I want something more elegant than using an international adapter. Can't seem to find any 750mA chargers online.
But what I don't get is what the smart chargers are doing if it's the battery that determines the power that's pulled. And how is one supposed to know if a smart charger is fully compatible with a phone. Seems like lots of irresponsible branding out there.A 750mA charger is just what comes with the phone. It's not required to use it, but any lower mA would cause a very slow charge, and some chargers that have a higher mA could possibly shorten the battery life, as it may not be a true smart charger that is compatible with the phone.
Where do I confirm this, that the 640 is Quick Charge compatible? It's not anywhere on the 640s MS page. I'm not saying you're lying, but again as per my previous comment, how are we the consumers supposed to know that?The Lumia 640 is Quick Charge 2.0 compatible, so I'd recommend you pick up a Quick Charge 2.0 certified charger. It will charge your device faster and more efficiently without causing damage to the device. Just do a search online for "Quick Charge 2.0 Certified Charger" and you'll find plenty.

EDIT: A bit of reading on the Qualcomm site brought up the fact that QC 2.0 is available on the Lumia 640's Snapdragon 400 processor. Now I just need to learn how QC works because I find it fascinating. So, is there any one QC charger brand that is best?
So, this has NOTHING at all to do with USB3.0 and 2.0 because that's about data transfer rates, correct? So are these QC ports USB 3 or 2 or non-relevant?
No, no. Not at all. It's fascinating.Okay, Too Much Info, I know.
Looks like a solid charger. I have found my 5 port charger to be invaluable. Easy to throw in a bag when we travel without having to take a lot of adapters and search for multiple available outlet plugs at the hotel. Simple. Easy. Love it. Mine is only 50W instead of 90W. You would be getting a much better one than what I have, but I don't have any tablets to charge, just 2 phones and a couple of Bluetooth devices, so 50W is more than enough for me (not to mention I got it for half the price of the 90W version.)I'm thinking about this one from Tronsmart: Tronsmart Titan 90W 5 Ports USB Desktop Charger (US & EU & UK Plug in Black) | Tronsmart

No difference that you can notice, I'm sure. Many chargers can charge as fast as QC2.0 simply by providing enough current to the phone to get it charged quickly. However, its not always the healthiest for your battery. QC2.0 works with the circuitry inside your phone to slow down charging as you approach full to prevent damage to the battery. No, it doesn't charge the same way. It will charge it as fast as your battery "should" be charged.I have charged my lumia 730 with a Aukey QC2.0 charger, it still charges at the same way. No difference . Snapdragon 400 is outdated anyway.
You don't always. There is always the danger of false advertising that will say certified when it isn't, and some won't say it when it is. This particular one looks legit, however. The one thing I always do is stay away from products that have not been reviewed. I read reviews on Amazon, and I search for reviews from sources I trust on the internet (not just anyone.)How do you know if one you're looking at is definitively Qualcomm Certified? The Tronsmart Titan I was mentioning doesn't say certified but it has the Qualcomm logo which I assume they can't just print unless Qualcomm approves, no?
