I've had two in use for a couple of years now and there still working very well.
My biggest complaint, in fact, my only complaint, is that their powerIQ doesn't switch gears when I connect different devices. The purpose of PowerIQ is to optimize power delivery for your device, whichever device that may be-- rumor is there's more than a few you a fast charge when you plug in your Galaxy S10 Plus, or normal charge when you plug in your Apple Airpods gen. II. The only logical cause I can find is perhaps the charger was built before those models were released, and so there is no configuration template to match it with Qualcomm's fast charging technology, and not an individual device.
Well, rumor has it that there's more than a few different device types out in the world today, but of them all, I didn't expect my Anker powercore 2000 to not recognize Samsung's flagship phone. Go figa.
(for the record, I would probably by the same unit again, even knowing what I know now.)

Anker is a great brand and would definitely get another battery bank from them when this one dies!
Actually it stayed in my truck I handled for about 8 months. Bottom of the console. Couple months ago one of my guys needed a way to keep his phone charged since he listens to music as he works. It was still fully charged, and still works great. I'm quite impressed. The truck gets hot sitting in the Texas heat, which can cause issues for such things, but not this.
Sucks it takes a long time to charge up, always has, but it keeps my guys phone charged around a week with constant use during day. Seriously, it's mine, he needs to rder his own 😟🤪 lol
Originally got a couple for my Vive, which I don't have anymore. Didn't ever use after that, just had in truck for emergency use.

The charger comes with a cushioned sock that provides a bit of protection, I plug the micro USB cable in and tuck it within the sock so I never lose or damage the cable! [Shown in picture]
It's 3-4 cm longer than my phone so still fits into my coat/jacket pockets with ease!
Cons:
A more detailed battery level indicator would be useful, it has 4 little LED lights which are good enough 99% of the time but it would be nice to know the exact charge I have left when I am below 25% capacity so I can be more conservative if necessary.

With the HTC cradle in the locked position, the battery slides in nicely and holds quite firmly.
Unsure at this point total battery life; however, after a couple of hours playing, one light went out, suggesting only 1/4 of the charge had been used, and controller charge was about the same suggesting like for like, therefore battery should last one complete controller charge, which is fantastic.
Sticks out of the HTC cradle top but hey, seems secure and seriously longer lasting than the 2 hour charge of the 21W Lucent Trans provided with the Cosmos wireless kit. Ordered another to have one in use and one on charge. At four times the power and nearly half the price, so grateful that a well recognised brand has produced such a cost effective option.
On initial charge two of the four lights were lit. In a QC 3.0 USB charging slot, took four hours for charge to register as complete, therefore expecting an 8 hour charge from zero. If I do run to empty at any point, I’ll update with total time to charge, which from the outset is looks promising.

Arrived more quickly than expected after ordering it in mid February, and I appreciated this, but I've already realised that this purchase might not have been a good one. This charger is replacing a brand new £30 PNY 20k charger which seemed to be moody about charging my phones. Still, that charger seems to have been better quality than this one, lasting longer between charges. I have a brand new S9, and it's almost like I can MAYBE get about 2-2.5 charges from it. It's difficult to say because I don't tend to let my phone's battery get too low. In short, I'm already thinking about returning this. I've already had it die on me once. I literally rely on my phone to help me to earn money to support myself so, yeah, I'm not sure that I will be keeping this product.

This may well be down to the fact that the output is lower than that of a Oneplus quick charge. Such a shame really.
Overall, the item is very sleek, quite heavy (what do you expect from a 20k Mah battery) and seems robust.
Very very surprised this didn't have a USB type C input. that certainly was a shock, maybe Anker have a lot of other ports to get rid of.
Charge time to full from flat, you are looking at around 5-6 hours, i like the minimalist look and feel, overall it's quite a good powerbank so far. will update more after a while testing it.
Next model Anker, lets go for USB type C input and output? Inclusive quick charging of all devices. Maybe a minimalist plug top? one that folds up into itself for easy storage while carrying in the provided mesh bag? not everywhere has USB outlets to recharge the unit.
