For faster charging

I will give it 5 stars on the condition that I knew beforehand that it is bulky. In terms of size, it's like having two Xiaomi Mi 10000mAh power banks stacked on top of each other and it weighs almost half a kilo. So far, it's working well, charges and recharges quickly. The only strange thing is that the discharge rate doesn't seem to be smooth. I will keep an eye on it.

After six months, I can say that its performance is very good. What doesn't work well is the battery level indicator on the screen when it's being discharged. It works fine when it's being charged. However, if I plug my phone to charge while the power bank is at 9%, it can charge for 35 minutes and consistently show 9% and suddenly drop to 1% and then shut down shortly after. It charges properly, it can fully charge a phone with a 4500mAh battery four times, but the screen indicators are not reliable.

It is gigantic and heavier than a blue whale.

Or maybe not.

It is perfect for the things I want it to do, especially for its price point. It has a large capacity, I can charge a tablet and 2 phones and still have 25-30% left, and if I could, I would also charge my laptop. Although it has significant weight and volume, making it difficult to carry in a pocket, it doesn't bother me in any way when it's in a bag, even a small one.

It has 2 USB-A outputs, 1 micro-USB input, and a USB-C input/output, which is simply perfect as it can charge at least 3 devices simultaneously. And although it shouldn't be done as it can damage the device, I used it as a splitter-power strip during a camping trip, charging 2 phones while simultaneously charging the power bank.

Flawless construction, plastic but good quality, it has a useful little screen, and I feel safe having it since my work requires intense use of a tablet and phone

I will start by saying that it is not a power bank to put in your pocket and go, it is bulky and heavy, if that doesn't bother you then it is worth it.
Abundant battery capacity, around 16000 mah approximately.
Charges devices quite fast and charges itself at the same speed, with the charger I have, 5v 3a, which is 15w, it took about 6 hours to charge, so if you have a better charger it will be even faster.
Plastic construction quality but it seems solidly built, pleasant addition is the screen that seems to work correctly.
In the package it includes a cable, unfortunately micro usb and not type c for all the rest, time will tell what happens, I will come back

This specific power bank is very good, it charges my devices quickly without dramatically draining its battery. It easily gives me 3-4 charges. Personally, I bought it to charge my phone-tablet at work, and what I want to conclude with this is that I have it permanently in my backpack. If you have it in a bag with you, you can transport it, otherwise it is difficult due to its large size and weight. I highly recommend it!

Good device but very heavy.
For charging inside the house that I use it is ok, but there is no way to carry it with you.

In the one month that I have had it, it works fine, charges small devices (phone, watch) quickly, and seems to have satisfactory capacity.
The dimensions are somewhat large and it is a bit inconvenient to carry.
I use it mostly for auxiliary charging at home.
Update: I used it for three weeks at the beach in the summer, charging an iPad and a phone at least once a day to full charge, and it still had about 20-30% remaining.
I believe it is a good purchase (I bought it on sale for 22 euros), the only drawback maybe its weight, although it is probably unavoidable.
Total charging time from 20-30% to 100% is approximately 3-4 hours.
