Question for Tech Savy People
#1
Recently purchased an LEDLenser flashlight, I like this brand!
In the ad the company mentioned the "torch" as they call it
has a built in USB 3.0 system for "super-fast" charging.  So
I guess since 3.0 is faster than 2.0 it must also charge faster.
Am I missing something here?

Most of my flashlights are USB/AC rechargeable, rarely use
store bought batteries.

USB 3.0 has a higher data transfer and charging rate than 2.0. USB 3.0 supports .9 charging amps vs USB 2.0 with .5 charging amps. 3.0 ports are identified by a  port with a blue colored insert. 

If you are using a USB compatible AC wall adapter or car charging adapter, it will need to support .9+ amps per USB port, otherwise charging will not be any faster and you could overheat the charging adapter.

So I assume the USB connector will be different than your standard "mini" USB
like most non Apple cell phones use.

The blue insert is on the socket of the device intended for the 'big end' of the USB cable.  The mini-USB connector won't be significantly different.

Most devices using USB3.0 are 'backward compatible,' meaning that if you use a USB2.0 device to charge (from), it'll only charge at USB2.0 capabilities.  If you're using a USB3.0 device to charge (from), it'll work fine... but if you're charging a USB2.0 device using a USB3.0 charging device, the USB2.0 can only receive as fast as it can receive, and the USB3.0 device should adjust its output accordingly... so it should be fine.  As rackerm mentioned, you'll want to monitor any device being charged, just to make sure it doesn't overheat and things go bad.

Don't be like my wife - she leaves her cell phone on the charger for a whole day, when it only really needs about 30-45 minutes every other week for a full charge.  Granted, it's a POS flipper, but still.   whistling

Your charging adapter will have a labell on it stating it's output capacity. USB 3.0 compatible chargers will have an output of .9 amps or higher for a single USB port. For mutli port adapters multiply .9 by the number of usb ports. Newer fast charging chargers will say 1A or 2.1A next to the USB charging port indicating their capasity.

I last charged my trusty ol' flipper the Monday before last... still has all bars on the battery.   Cool

Got a wall charger that is rated at 3.6-6.5V at 3A, that should work.
