Looking to buy a power bank for camping trip coming up

looking for around 20'000 mAh

and there seem to be lots

what i am mainly confused about is if QC3 is worth paying for
there are loads with 2.4A outputs (about 10W).

i will also be buying a QC3 car charger for phones and power bank

i want one that does two devices, they almost all do.
and has some sort of power meter on it.

the one i am looking at has usb C in and out and QC3 in and out too

would you guys go for QC3 over 2?

the device is about a 1/3 more expensive than the numerous QC2 and 2.4A in/out chargers
 
Ive got 3 RAVPower none are quick QC3 but all 3 have been great ..oldest is 3 years and still holds charge for weeks

they do QC3 so will be hopefully buying one if the Note 7 is Usb c
 
Bare in mind most of these big battery packs use a bunch of 18650 batteries which the good ones aren't cheap (around £3-4 and upwards for a ~2400mah battery even bulk buying as a business direct) so if its much cheaper than the Anker packs they are probably using reclaimed/refurb cells which can be a bit hit and miss - could be great or could have very limited life left in some of the cells.

The rav is actually more expensive than the anker

Was more a general reply to the first bit of your post:

"and there seem to be lots" its one way to filter out some of the options when at the price they can't possibly be using decent grade cells.

Got you.
Yeah I'm down to two branded ones
Seems to be differing opinions as to if anker IQ charging is any good or not.

On paper its very similar to QC 3 (amps * volts = power)
What I don't know is of a QC phone can utilise all that if it isn't QC certified

Ie, can a QC3 phone utilise the same power from an IQ port as a QC port
 
I seem to recall its the voltage that is important for the quick charge performance as there is an upper limit on amperage for the charge controller constant current part of the cycle that is the same whether 5v or 9v quick charge so there is a limit to how high amperage is a benefit.

I'm that case the non quick charge ones are a bunch of balls then
The Rav can go to 12v bit the power iq just up the current and keep the volts at 5
Didn't realise voltage handling is what makes QC what it is

Thanks buddy, that makes the decision easy!
 
From what I understand power iq allows for devices that can negotiate for non-standard/higher current to do that but it doesn't enable the same feature set as the QC standard so won't give as big a boost on those devices compared to if they are enabled for QC. However the device has to support QC to take advantage of it.
