I have been using it non-stop for 19 months as a UPS. I have connected the WIND router to it (You need a USB to DC plug cable for the router) and the alarm hub to the router's USB. During a power outage, it provides power for 8 hours and simultaneously charges from a Xiaomi 66w power adapter. It heats up as much as the router does, which is normal.
Very useful mobile accessory, headphones, etc. For the Xiaomi Poco X5 Pro I bought this specific power bank and I charge it 5-6 times until the power bank battery is fully drained, very good purchase especially for trips now in the summer it is what you need, just when buying a power bank look at the characteristics of your mobile phone until you make sure it covers you.
In the positives:
Sturdy construction
High quality
Two ports, can charge two devices simultaneously without any problem
20000mAh battery
When I first got it, it charged my iPhone 7 about 7 times and a Xiaomi with a larger battery about 3 times
One port has regular charging and the other has fast charging, it charges both Android and iOS devices, especially Xiaomi devices, in no time
It has fallen countless times and still works perfectly fine
In the negatives:
After about three years of use, even if you fully charge it, the battery life doesn't last as long as it used to, and it's very noticeable because I charge exactly the same devices as before but the power bank's battery doesn't last the same
It also requires a longer charging time, it takes several hours to fully charge again, especially after heavy use, so I imagine it's perfectly reasonable in combination with light mishandling
Its size is not practical, it's too heavy to carry with you all the time to the café, on vacation, or on a walk. It won't disappoint you, of course, but one should keep in mind that this specific power bank is not portable. However, considering it has 20000mAh, I find it very reasonable.
Charges very quickly, the voltage it supplies to a mobile phone is 55W, it charges it in less than 1 hour, and it can charge a 5000mAh mobile phone 4-5 times with one device charge.
I have been using it for 2 months in the army. It has not shown any problems. It's really reliable. It charges quickly. It's perfect for the army, charging my phone or another device. It lasted me 4-5 full charges.
***Note that it only has a Type C port and supports 55W charging.
I was very satisfied with the purchase. It charges satisfactorily fast, it is durable, and you can charge your phone 3-4 times. On the downside, it is relatively heavy and bulky. You definitely need a bag to carry it with you.
Very good power bank that looks compact, with excellent construction, beautiful matte finish, convenient shape to hold (with rounded edges) and for 20,000mAh I would say it is quite compact (maybe a little heavy) and fits in a (wide) pocket. It has three ports, 2 USB-A for slow charging of devices and one USB-C for fast charging 45W which is both in and out. As for the speeds, it charges my phone and tablet (which have 45W fast charge) slightly slower than their charger. I haven't measured the current passing through but this means that it captures slightly less in watts, without the difference being significant. The times are very good. It charges itself in just over 4 hours with a fast charger which is a reasonable time for such capacity. The 20,000mAh is indeed the actual capacity and it will charge a phone with a 5,000mAh battery almost 4 times, which means minimal losses. I don't know if it has sufficient voltage to power larger devices, such as laptops, while they are in use or if it will simply charge it closed. Overall, however, it has a reasonable price for what it offers and is a very reliable solution for travel and trips.
At the price of 50€, it is a must if you are looking for something good that will last. It holds up to 4 charges (S22 mobile) and charges it from 0-100 in about 1 hour. In short, a very good power bank. Highly recommended.
You know what you're getting, it's a sleek brick. I got it for the army to charge quickly and several times, it gave me 4 charges each time from 10-20% to 100% with a full charge on a 4000 mA battery
So, I had the same one with the 18W but upgraded to this one because I wanted faster charging. The power bank provides up to 33W for devices that require power delivery. I have a phone that supports 45W and a laptop that supports up to 100, but both only draw up to 33W for some reason, probably because they don't have power delivery technology and only have fast charge. It's a small negative, but it's not a problem for me. It was definitely worth the money, but just so you know, I mentioned the above.
Update 4/24: It has an issue where it goes to 50% and if I charge a device with fast charging, after 5 minutes it goes to 0% and doesn't recover until I charge it
Wonderful! I wasn't looking for a power bank, but they gave it to me as a gift for my birthday and I loved it. After months, I dropped it in water and they bought me another one, the same one.... Still wonderful, I am fully satisfied.
First negative: heavy and bulky, you definitely need a bag.
Second negative: the casing is matte, so it easily scratches.
However!!! With what it offers, these negatives are nothing.
It's also 20000 mAh, so the size is justified.
Xiaomi power banks are the best! I know people who have all sizes (even the very small and medium) and they are indeed good!
It charges quickly, especially for me who has a fast charger (iPhone) and if I remember correctly, I can charge it up to 4 times
Tool. I bought a USB-C to DC 12V cable and I power a 12V/3A pump (water gun) at the beach so that the little one can have a hose with seawater to make lakes and rivers. The little one plays for hours. It lasts comfortably for 2 hours with one charge. One day it got too hot because of my mistake (I left it exposed to the heat) and it stopped on its own. After I put it in the shade, it started working again in 2 minutes. Excellent as a classic power bank - with USB-C it provides very fast charging.
I took a 13-hour trip on my vacation and used it on the Steam Deck, which requires 45w, no complaints so far. With the deck's charger, which is 45w, it took me about 4 hours and something to charge from 0-100%.
If you want 20,000mAh.....the volume cannot be smaller with current technology. So whoever complains, does it unfairly. The product is correct and honest.
This powerbank fully charges a Xiaomi F3 POCO phone and a MacBook with one charge (powerbank charging time is approximately 6 hours). If used only for charging my phone, it gives me 4 charges. The phone charging time is equivalent to being connected to a fast charger. I've been using it for almost 2 months and it has already saved me several times!
Excellent performance and charging speed for mobile phones and accessories. It charges a POCO F4 three times. It is naturally bulky and heavy, but it is 20K so it can't be helped. It comfortably fits in a slightly larger than normal men's bag. Recommended.
It charges quickly everything I've tried (phone, tablet, headphones, controllers...). The only downside is that it's heavy and bulky compared to other power banks. It's definitely worth the money though, even if it's heavy.
Quite good for now. It gives me about 5 mobile charges. I also charged my smart band, headphones, and Asus rog laptop from its type c port. I didn't leave it on the laptop for too long to know what it would do. But in 10 minutes, it gave me 7%.
Very powerful. It charges two iPhone 13 mobiles and wireless headphones in a short time. It's a bit heavy but powerful. It takes 7 hours to recharge. And I usually put it at night so it's ready by morning. I highly recommend it.
I highly recommend it! It charges my phone (4100mAh) from 15% to 100% 3-4 times before it needs recharging! And believe me, it's very fast! Sometimes I forget and let my phone drop to 7-8%, but within 10 minutes it's easily up to 20%! (All of this, of course, with a type-c to type-c cable or if you have an iPhone, type-c to Lightning.) It also charges two other devices through a regular USB 1.0 port!
Now for the negatives...
It's heavy and a bit bulky... Also, it definitely takes 4-5 hours to fully charge... (Personally, I just charge it overnight and it's good to go in the morning!) In short, if you're on the go all day or travel frequently, you need this tool!
The charging speeds are real. It also charges very quickly. In size and weight, it is as expected from a 20000mAh power bank. I recommend it to anyone who wants a high-capacity and high-speed charging device.
Perfect in every way!! I bought it to charge my Macbook pro 16" during a sailing trip where we would be without power and 2 years later it still works great. It's one of the few chargers that produces 45w for the price, and when paired with the 96W charger from the Macbook it charges incredibly fast, from 0-80% in about 1.5 hours. It would be more practical if the lights worked like the DJI's, showing more information with different blinks every 10% for example.
For the 35€ I paid, I can't ask for more, but now that I see it's 60€ for a second one, I don't know.
