**Update**
I got a new "power delivery" charger, and it now charges in a reasonable amount of time. Having used this backup for a while now, I can highly recommend it. It has been a life saver, and... The battery lasts for a long time.
**Original Review**
I ordered this for when my wife is at a craft show all day without any power plugs and needs to keep her phone charged in order to accept credit card purchases. For charging a phone it works great!
It arrived with maybe 25-40% battery, I plugged it in to charge (with my qc3 charger), and after 2.5 hours it was still blinking less than 50%. My first thought was... Wtf, the description said it charges back up quickly... My second thought was to check the "instructions". I found out that the instructions are completely useless, so I then googled it. I found the answer - in order to quickly charge this unit (20,000 pd), you need a "pd charger". Seems there is a special usb c high capacity "power delivery" charger that is around 45w for the usb c port. With this additional charger, I can charge this unit faster (supposedly - mine is on order now). I'll update after getting the new charger.
Pros:
- comes with a charge
- comes with a USB C to USB C cable (1-2 feet)
- nice design, feels well built.
- a button to easily see the units current charge
- charged my phone fast
- while it doesn't look like it will fit into the included bag, it fits nicely. :)
Cons:
- requires a specific charger to charge in less than 15-20 hours.
- instruction manual is useless

Anker is good
TL:DR - Anker is kind of a fantastic brand. You get exactly what's promised and the quality of their products is super.Reading the reviews I find that a lot of people complain about slow charge time or about it not appearantly the capacity it states. I haven't had this issues with my battery.I took some time to see how many times I could charge my phone and it fell just about on the mark. It wasn't done with proper instruments. I simply let my phone with a 5,000 mAh battery get close to 2% and the I would charge it all the way up. I got about 4 full charges until the battery stopped charging my phone. Ended at 93% which to me already is on the money but even still, there was a night I just left my phone charging as I slept so it definitely got more than it's fill.There's also complaints about charging the battery itself and again, I didn't find this problem with mine. I timed how long it took to fully charge and it was actually a bit shorter than the stated time. Just about 5:30 hours. I didn't even need an anker branded charger. I used this 18W charger I used already to charge my phone. People might be forgetting just how massive 20,000 mAh is.Charging my phone was also just as expected. It charged it fully just as if it was plugged to the 18W charger which is to be expected but you know... I kind of still didn't cause it's a portable battery.Overall, Anker is kind of my go to for when it comes to electrical devices. I don't see them cutting corners to get there products out and for that I trust their brand. I feel like my devices won't suddenly burn out cause of bad components or that the hubs won't provided the performance promised. Idk, you should definitely give then a try
