The charge took around 16 hours which is around 6 hours longer than my old powercore. I will.drain them both and do a back to back comparison.

1) quite big, but probably just about fit in pocket
2) I have a OnePlus 6 phone, and these phones are know to be one of, if not, the fastest charging phones on the planet, so require powerful chargers. But this power bank chargers my phone really fast (I'd like to say 2/3 the speed of the wall charger.
3) Easily charge my phone 3 times over from 0%-100%
4) Has 2 fast USB charging ports (I believe 3.0?) And also has 2 ways of charging the bank, via standard micro USB, or c-type. But they are for charging the bank only.
It has such a nice feel to it and a really nice fine crisscross design on the top which gives it a nice textured feel.
Nice and sleek button and light design.
I've purchased 3 Anker power banks and they're all really nice quality build, look and feel, as well as great charging speeds. There's not much out there that charges my OnePlus phones, but Anker always deliver performance and quality.
I would recommend...don't be left without a charger like those in the YouTube adds, buy one of these. Life saver for me

It holds charge well. It holds a lot of charge. It can charge a Samsung S10 quickly and many times. It's a bit heavy but that is expected. It takes a while to charge but that is expected due to capacity. I wish it could charge whilst plugged in but unfortunately it cannot be charging and also charge a phone. USB C helps too
Pros
1) Good amount of charge and power in this thing
2) Good build quality and doesn't feel as though it'll break
3) USB C is convenient for charging it and easily copes charging 2 things at once
Cons
1) Quite heavy but expected
2) Can't charge at the same time as charging another device
About the Powercore Essential 20000:
- The product is very easy to use with LEDs indicating how much charge is remaining.
- High capacity meaning you can charge a phone fully several times. Will also charge Ipads.
- Can be charged via USB-C or MicroUSB
- Can charge two devices at the same time
- The build quality feels solid
- Includes a mesh carrying pouch
I highly recommend this product and Anker as a company as their customer support is some of the best I have experienced.
