I have not had it for more than 1.5 years, it seems like the battery has swollen and the charging duration has decreased, not even once... but for the money, what else do you want...

Charges quite fast any mobile phone I have connected to it, both with regular charging and fast charging, high-quality and sturdy, with the only negative being its weight.

It delivers on its promises in terms of capacity (2 full charges for a mobile phone) and with the option of fast charging. It has a long recharge time and is relatively heavy, but with good quality. However, for its price, it is worth it.

Unfortunately, after exactly 2 years, the Quick charge 3 stopped working and it charges the devices VERY slowly.

Having tried 5 different power banks, by far the best... slim and elegant... fast with 2 charging ports, one 2.1 and one 3A, it is the best I have ever used in a power bank... maybe more than 3 full charges from zero battery on an s10e, lasted 2 years with intensive use by 2 people...

I bought this specific power bank about 1.5 years ago. At first, everything was fine, but then it started doing its own thing. Sometimes it wouldn't charge, and sometimes the button that turns on the indicator lights showing the battery level stopped working. After 1.5 years, it completely broke and stopped functioning. I opened it to see if something had disconnected, and I saw that the battery inside was labeled as 5000mAh. They sold us a power bank advertised as 10000mAh when it actually only has 5000mAh. Well done, company!

Excellent build quality. My phone supports fast charging and in about half an hour it reaches from almost 0% to 60-70% and charges it at least twice. After 7 months of frequent use, its performance has not decreased at all. Good and reliable choice.

Quite good power bank, I charge my phone and occasionally other devices. It can do two full charges on a phone with 4500 mah daily, not completely emptying the phone's battery. I start charging it when the phone's battery reaches about 25% and it gives two charges. I have had it for about 8 months now and everything is fine

I bought it for 15 euros. It's really excellent. It charges my phone (s10+) as fast as the official charger. I haven't fully drained it to know exactly how many times you can charge the phone, but with the 10000 mAh, I estimate that my phone can be charged two and a bit times.

I also talked about it in one of my videos here: https://www.youtube.com/watch?v=bjgxTEcZ_qA

In terms of size, it's slightly smaller than the Samsung s10+ and a bit heavy, but it doesn't bother me.

At least 3 full charges on a mobile with a 3200mAh battery. Supports fast charging and is relatively small compared to others in its category. Overall, a very good power bank choice.

It takes many hours to charge, for me it charges in 10-12 hours, maybe even more. Personally, I don't think it's worth it. I bought it 4 months ago for 22-23€. In the beginning, during the first month, it was very good. It charged my phone (Huawei Mate 10 Lite, 3340mAh) about 3 times and quickly. I haven't used it more than 20 times, and those 2 times were full charges from 0% to 100%. Its construction is good and durable, but now it doesn't charge my phone AT ALL. It only charges my phone from 5-6% to 45-50% when the power bank is fully charged. I do not recommend it at all. I would advise someone to get the Xiaomi power bank with the same price, but not 10000mAh, rather 20000mAh. I have acquaintances who have been using it for many months and it's as if they have only used it 1-2 times.

Update 2020! It still works without any problems, after 3 years of use! The only thing that broke relatively quickly was the built-in micro-USB cable. I recommend it!

Very good for anyone who wants fast charging for their device.. unfortunately, it takes a long time to charge the power bank (in my opinion, the only area where it lacks)..

The device does its job excellently! The fast charging works great as long as your device supports it, and even the regular charging is not just regular because it charges very quickly. The weight is perfect for a 10000mAh power bank with a metallic chassis, so don't complain! Clearly, it's value for money!

One of the best choices someone can really make!
Made in Germany, you can buy it with closed eyes as besides being absolutely reliable, it supports fast charging, which is very important for most smartphones.
Personally, I have been using it on a Samsung Galaxy S7 Edge device for about half a year and I am completely satisfied. It works like the first day!!
Excellent 10/10 from me both for the product and its price (around 20 euros).
Anyone who has an issue with the size - volume simply goes for a smaller capacity Power Bank.
Even here, however, its weight is normal and its shape is very convenient and practical so that you can keep it together with your mobile phone.

It is a pretty good and honest power bank. It easily charges a 4000mAh mobile phone twice from low battery to 100% before it discharges itself. Therefore, we are talking about a very good 8 out of 10, not a 10 out of 10. The pros include Quick charge 3.0, two USB outputs (QC3 3A and one 2.0A), and the beautiful and high-quality construction. It is a bit heavy, but it is easily portable because it is thin and relatively compact as a power bank. As a seller, I recommend it as a reliable choice!

Nice finish (be careful it slips), a bit heavy. When I received it, it had 2 charging lines out of the 4 it has (green lights). I charged it for exactly 3 hours and it reached 100% charge. Then I tested it on a Samsung j7 2017 with a 3,600 battery, and with 2% charge, it took 2 hours to charge the phone to 100%. The Intenso went down to 2 lines (green lights). At the price of 15.90 that I bought it, it is worth its money. I consider it a good choice.

It is not heavy. We must understand that it is not a 'mobile' 'tablet' 'smartwatch' etc. It is a portable BATTERY. Batteries with large capacity are heavy. It is worth its money, it has a large capacity, and the fast charging function is very positive. It is indeed a bit large, but consider that there are larger phones in terms of volume.
4 stars because nothing in the world is perfect

I bought 2 for myself and my wife. The price is quite good.
It easily charges a tablet 4000mAh twice.
It takes a while to charge, but it doesn't bother me.
Sturdy construction and beautiful.
A little heavy though, but we can't have it all.

It charges the P10 very quickly but takes a long time to charge itself. It doesn't bother me because I put it overnight. As for the size, it is very good but a little heavy. We can't have it all!! Very good power bank!!!!

Very good. I have no regrets for choosing it. It charges my phone very quickly (quick charge) and at the same time, it charges as fast as my phone charger (S7 edge). It can charge 2 devices simultaneously and has a battery indicator. It is lightweight for a 10000mAh power bank and it is not bulky in size. The only negative is that it takes a while to charge the power bank, it definitely takes about 3 hours, but it doesn't matter to me as it satisfies me in all other aspects. I highly recommend it!

Although I just bought it and I don't have a complete opinion yet, I decided to write to solve some doubts I had before buying it.

1. It has the size of an s6, but it is thicker.
2. It is heavy (like a small tablet).
3. It charges 2 devices simultaneously, but both in regular charging. It does not have quick charge when you have 2 devices.
4. It is fast.
5. If it is <30%, it first charges the power bank to reach 30% and then the device.

4 stars for now, and soon I will complete the review.

The definition of a fair purchase. Very good build quality, extremely fast in charging devices, compatible with Qualcomm Quick Charge 3.0 (and previous versions). Very fast in charging the power bank itself, although it only has a 2.1A input and not Quick Charge.

Very good construction, charges my phone (galaxy s8+) about 3.5 times and supports fast charging on Samsung devices that have this capability, something that is not mentioned in the specifications. The best for the money. I highly recommend it.

If you want to get a power bank, this is one of the best. It has quick charge 3.0, which means it charges devices that support this function much faster without meaning that it doesn't charge other devices. It also has a very good design, although I found it a bit heavy. With a full charge, I charged my phone 4 times without the power bank's battery running out. The only complaint I have is that it doesn't charge as fast again... although I don't consider it that important for the approximately one month that I have it. To tell the truth, I didn't expect it to be so good for its price, but it is one of the best power banks and for its price, I believe it is the best.
