It's simply perfect! I use it together with an Anker charger and I am absolutely satisfied.

What I liked (Pros):

The built-in USB-C cables: At first I was hesitant, but in the end they are a lifesaver! It's so convenient not to look for cables, that now I prefer it over all the other power banks I have.

The speed: It charges my Apple devices lightning fast, especially my MacBook Air M4.

The quality: It seems very well built. It's definitely an excellent idea for a gift too!

What to watch out for (Cons):

Needs a good charger: If you have a basic charger, it might take you 5 hours to fill the power bank. Luckily, with my good Anker charger, I fill it quickly, in about 1 hour and 45 minutes.

Heats up under heavy load: If you connect very demanding devices for a long time (it can deliver up to 100W to one device), it heats up and goes into "cooling mode," slightly reducing the speed to cool down. Nevertheless, it remains very powerful and does its job comfortably.

It's an amazing purchase, even for those with high-demand devices. I recommend it with my eyes closed!

Without exaggeration, at this moment this is the best power bank I have ever had in my life. It gives you a huge energy reserve, which it provides very quickly (with a maximum total output power of 165 W). The two built-in USB-C cables eliminate the need to carry any additional cables with you. One is braided, very durable, and also serves as a carrying strap, while the other is longer, particularly flexible, and coils/uncoils like a spring inside the power bank. Besides these, it has two ports, one USB-C and one USB-A, so in total it has 3 x USB-C and 1 x USB-A. There are many smart features that make it stand out. The power bank "wakes up" automatically when you uncoil the cable, so you can immediately see the charging percentage. If multiple sources are connected to it (for charging the power bank), it automatically selects the one with the highest power. You can connect multiple devices to it, which it charges simultaneously. If you press its button twice, it permanently activates the USB-A port (it doesn't power off), allowing you to properly charge small devices, such as wireless earbuds, where other power banks turn off before they are fully charged. It supports Pass Through function, which allows you to charge the power bank while it simultaneously charges other devices. Its display is magical. It shows you the charging percentage of the power bank, the individual (per port) power values to and from the power bank, the temperature, battery health, and some other messages about the status of the power bank. It is quite heavy and relatively bulky, but this is expected due to the 25,000 mAh capacity and the cable winding mechanism. I don't think it could be any better. I congratulate Anker for a truly user-friendly and particularly well-designed product, both functionally and aesthetically. If weight and bulk are not an issue, it will fully satisfy you. I highly recommend it.

I won't hide that I didn't know the Anker brand until I saw it from the Unboxholics! I have used other powerbanks but this one is very nice by far!!
First of all, the build quality is wonderful! You hold it in your hands and you feel that it is made from good quality materials.
2 built-in type C cables so you don't need to carry extra cables with you!!
It has a small screen but with information I haven't seen on any other powerbank! This is great because you see the exact battery percentage (like 85.76%). You see at how many watts you are charging and at how many watts the power bank is charging. And when the powerbank is charging it also tells you how much time is left until it is fully charged!!
The screen also has a battery health indicator for the powerbank, shows temperature, and when you are charging multiple devices together it shows how many watts are being delivered to each device because it displays all the input + output ports on the screen.
Finally, 25000mah is just fine if you consider that you can charge a 5000mah phone 4-5 times, you can even charge a laptop with the right cables. It provides very fast charging and supports high speeds.
Obviously, it's a bit heavy but it's totally worth the money!!
I was absolutely satisfied and in the future I will definitely prefer Anker or Ugreen product brands!! Guarantee.

We're talking about a beast! At this price, you can't even buy a charger (adapter) with such power and so many outputs!
It charges 4 devices simultaneously with a total power output of 165W (100W maximum per output).
And it charges a laptop perfectly well, at 100W speed (if you haven't connected another device to the Power Bank).
It also charges itself very quickly via the USB-C port at 100W speed, if you have such a charger at home, as well as the right cable.
Parenthesis: be careful with USB-C cables, many are low power and we think the charger or the Power Bank is at fault when a device charges slowly, but in reality, it's the cable's fault.
You can also alternatively charge 3 devices and at the same time charge the Power Bank itself (Pass Through function) via the 4th port, working as a charging power strip for devices.
The 2 built-in cables are revolutionary (no need to carry and connect cables)!
The information on the screen is very useful, with indications for the charging speed of each device, as well as the Power Bank itself.
As the only "flaw" we could mention that it's bulky and heavy, but what else would you expect from a tool of such power!
Also, it's good to know, especially during summers in Greece, that a power limit (throttle) may automatically activate to avoid overheating (as happens with computers and phones). When this rarely happens, there is even a relevant indication on the screen (that it can't operate at peak performance) and an active cooling system is activated (does it have an internal fan?). In practice, it was not a problem, performance was always good.
In conclusion, I tend to do away with chargers (I only use them to charge the Power Bank), since my devices charge faster and more conveniently with this tool than with (almost) any charger.
Only the 140W charger of my MacBook Pro compares in performance, but that has one output and costs 110 euros!
