I think these statements are contradictory. In other words, I don't think Canon makes a USB charger. The Canon made charger for the LP-E17 battery is the LC-E17.

This, https://www.amazon.com ...eras-LC-E17/dp/B01ICB1V10 (external link), will work off a car accessory outlet and is made by SterlingTek (STK), one of the better and often used brands of 3rd party batteries.

Another well known often used battery is Wasabi and you can get a charger (with car adapter) and two batteries at https://www.amazon.com ...p-e17+battery+car+charge​r (external link).

In both cases, take note of the limitations. The batteries may not be chipped and read information properly in your camera and you may only be able to charge the 3rd party batteries in their respective charger, not a Canon charger.

I suggest getting information from an owner of a 5V input (USB) battery charger, regarding the amount of TIME to charge a battery compared to using 110V US /240V Int'l voltage input.

The output rating from a Sterlinktek that I have for LCE6 (7DII) battery is 500mAh, compared to 1200 mAh from a Canon charger...only 41% of the charge rate!
The output rating from a CTA that I have for BP511 (40D) battery is 700mAh, compared to 1200 mAh from a Canon charger...only 58% of the charge rate

I bought my chargers simply to be able to charge while driving about, if not near an AC power source for a number of days. Rate of charge was not of primary importance to me. OTOH it sounds as if you want/need to recharge while 'on the job' and have depleted batteries that you need to replenish on the spot rather than back in your room that evening, so charge rate would be important.

Why not just buy a bunch more batteries? That would save a lot of hassle.

So I read the specs for USB 2 is 500mAh, and USB 3 is 900mAh. So you’re looking at a 3hr charge for a 1500 mA battery. The standard portable USB chargers just have a usb output for your mobile device to charge its battery (which is probably better from a longevity standpoint).

It's hard to follow this when folks mix up milliamps (mA) and milliamp-hours (mAh).

Hey, I just put 30 MPG into the tank today.

Waitasec, a USB rapid charger to charge a smartphone outputs 5V 2A supplied with phones in the past couple of years
"5V 2A Micro USB Travel Charger Portable Wall Charger for Samsung"

and older USB chargers have a 5V 1A suppy rating.

So they're not using the USB 2 protocol of 500mAh (and is that Ah?). RE: mAh....that is the main number to look at for recharge times (mAh means milliAmps per hour). I have a La Crosse NiCd/NiMH charger that lets you chose between 200mAh, 500mAh, or 700mAh. 200 is recommended for longer battery life. It does equate to a 10 hour charge time with my 2000 mA batteries completely drained. If I'm looking for a speedier time, 700 will do that in under 3 hours. Other chargers have higher mAh ratings, but you can feel the batteries get hot (and they do reduce battery life).

Chargers deliver current and the unit for current is the amp, or milliamp.

In the USB 1.0 and 2.0 specs, a standard downstream port is capable of delivering up to 500mA (0.5A); with USB 3.0, it moves up to 900mA (0.9A).
The charging downstream and dedicated charging ports provide up to 1,500mA (1.5A). USB 3.1 supports power draw of 1.5A and 3A over the 5V bus.

But there are plenty of USB chargers that don’t conform to these specs — mostly of the wall-wart variety. Apple’s iPad charger, for example, provides 2.1A at 5V; Amazon’s Kindle Fire charger outputs 1.8A; and many car chargers can output anything from 1A to 2.1A.

Actually for mA: USB 2 is specified for 100mA, 500mAh / 150mA, 900mAh for USB 3. Anyways, this is all academic for a hypothetical USB camera battery charger: typical examples of high grade chargers aren't quick at charging and a specific camera battery is a pretty small market.

We're comparing apples to oranges. My quoted specs are from the USB 2 and USB 3 are the standard downstream devices, while you're getting into max power battery charging devices. The typical battery charging load can reach 1.5A. Even if your charger gets that high with Ah, we're still talking over an hour charge with a drained battery.
