The charging of the bank is slow enough, but the charging performance of the connected devices is sufficient.
If you use a usb-c to usb-c cable with a 100W guarantee, then it can charge the Oculus VR for a very long time. Longer than you'd ever last using a stroke.
Other versions with a display that shows the percentage of charge are more fine.
The performance is comparable to similar products from Chinese mail order stores with a 20,000 mAh sticker, but this product is much smaller in size than those competing unbranded products also made in China.
It serves its purpose and does not sit in a drawer.

So far, I'm happy with Alzacek's.
Thank you so much for Pover Bank. I ordered yesterday and picked it up today. I'm satisfied. We'll see how it behaves. K Samsung A 14.
I don't know yet, I'll wait and see how it develops.

This power bank is a piece of garbage. I bought several pieces at once and it was a big mistake. The rated capacity for all of them is only 12000mAh. In addition, they squeak when charging, at night in the same room it is unbearable. Don't buy!
Capacity does not agree
It beeps when charging

After the first charge it does not work, charged the phone once and since then it can not be recharged. A great surprise on the way.
That's how alza can build its credibility. Scumbag. Next time, I'd rather have a trusted brand.

not charging
scumbag

For a product that has "fast charge" in the name, I wouldn't say it will take so long to charge. But its capacity makes up for it.
Large capacity
Simple and solid looking design
Slow charging
