Blackberry Q20 Charger Details??

Kindly Tell me about Blackberry Q20 Classic Original Charger Details. how many Amp.?
which charger is good with Q20 classic??

The chargers that came with them were rated at 850ma. You can charge from pretty much any quality charger without worry.

Get any QuickCharge 3.0 charger (models from Aukey and Anker brands on Amazon are excellent) and they will charge anything, from 10+ year old phones to the latest, at the fastest rate that the device supports.

There is absolutely nothing special about BB-branded chargers beyond the logo - they were all contracted out to begin with.

I'm using an 'ELLESYE' charger from Amazon (ASIN B078NC6Y3J) with my Blackberry Classic.

The phone stands in this one, so it makes a great phone stand and has a good view over the phone screen. Plus perhaps becasue the phone is standing up and heat can escape better, this one seems to make the phone not as hot as with the other qi-charger that I have, where the phone lays flat on top.

I have tested it on my 3x Classic. Two of them work great with it, meaning I just 'throw' them in and they charge, but my third Classic needs a bit persuation, meaning I need to play/move the phone in-out of the cradle, before the cradle light turns to charge green.

Charging speed is about the same as with the USB cable.
