After 3.5 years of occasional simple use, like on some trips, it swelled up and I will stop using it.
Nevertheless, I will buy the same one again!!!
The cables it has on it made my life so much easier.
I stopped carrying 200 cables with me on trips.
The battery is big enough to last you the whole weekend with 2-3 charges.
The price is excellent.
A bit heavy, but I don't really mind.

A recipe that works, you don't change it—it paid for itself in 3.5 years :)

Very positive that it has 4 types of output to charge any of your devices (usb a, usb c, usb mini and old type iphone)

Very good. It doesn't charge very fast but just the fact that you don't need to carry cables with you is enough. As for the 20K, it's plenty!! I recommend it

Very good and useful. It easily lasts for two charges. It is not very light, but that's reasonable for 20000mAh

Very good for its job.

A big advantage is the built-in cables.

A disadvantage is its heavy weight and bulk.

It charges relatively slowly but its battery lasts for at least three to four full phone charges. Also, it's very convenient that it has all the cables attached to it

It is very good. With a full charge, you can charge your devices several times. I was very satisfied, I always have it in my bag!!

Good for the money it costs, it takes about 6 hours to charge, maybe it can charge faster with a fast charger, I charge it with a 12 watt phone charger. It has 4 built-in cables for charging all the devices on the market, very practical, you don't have to look for which cable to take with you every time. Now, as for charging the phone, it charges it quite quickly, about three times until it runs out

It charges the phone up to 3 times at a moderate speed. It can charge my headphones and phone at the same time without any problem. The built-in cables are convenient. It loses one star because it is heavy for the bag and I would like it to be a bit faster.

4 months after purchase and with sparse use, it goes from 100 to 0 in 8 minutes.

Very functional power bank. You can charge several devices at the same time and quickly. 4 stars because charging the power bank itself takes quite a while. Otherwise, excellent.

Purchased 2 months ago, every time it was used its performance was really very good. I recommend it

It is very convenient that it has the cables attached and I don't have to look for them every time. It is a bit heavy but it has been very handy for me!

The only negative is its weight, but I knew that from the start and despite that, I bought it and it rewards me every day. Incredible tool, I highly recommend it.

Very good and it helps a lot that it has the cables on it, just when charging it requires a bit of patience but it's also 20,000 mAh so it's logical, it easily does four full charges

It has excellent performance and battery life. It charges my phone/headphones/speaker in a very short time and it's very convenient that I don't need to carry the corresponding cable I need. I highly recommend it!

Very powerful and reliable battery (charges up to three phones simultaneously) However, because its battery is large (2000 mAh), it has more weight than usual and will tire you out carrying it in your bag every day.

Basically, it is a good construction, but I wanted it to be Quick Charge and with the built-in cables it has, not just with the type C port. Update: Not even with the type C port is it Quick Charge; I changed cables but it still only does a regular charge, so from me, one star and let's go for another, since I can't return it. UPDATE 17-11 because I want to be fair, I will change the rating from one star to three, not because it charges quickly but because it can accommodate many devices for charging, although it is not fast in charging, it has been convenient for me so far

Very high quality and sturdy construction, with particularly convenient wiring for charging and being charged.

I wouldn't call it lightweight, but it does its job very well. It constantly shows you the charging indicator, so you know how much it has drained. It doesn't discharge unless you use it. You don't need cables or other accessories; it has them built-in. Very good. I highly recommend it.

Very good, it charges two devices simultaneously, maybe even three. It charges quickly in general. I believe the charging cables won't last long if you mistreat them

The battery lasts as it says but its charging is tedious. The built-in cables are convenient. I had it plugged in with a 30W charger and it didn't fully charge overnight!

Very nice power bank, it's worth every penny, it also has built-in cables so you don't need to carry your own cable.

The first charge took an afternoon even though it wasn't completely empty. Sturdy, well-made device, it doesn't have the features I need but it doesn't really matter. It charged my phone and also topped up my fiancée's quickly and only took 20%!! I hope it maintains such performance in the future!!!

Excellent, it has saved my hands and I always have it in my bag. The built-in cables are a great advantage as you don't need to carry extra cables. It can also charge itself from the built-in USB cable if there is a available brick. Throughout the day, it can charge my phone and iPad from almost empty to fully charged, and the power bank still has an extra 30% battery left. The charging speeds are satisfactory.

It's great, it charges an iPhone 4-5 times and has all the built-in cables one might need to charge a device or charge the power bank itself. I also use it as a power hub. By having it plugged into the socket, I can connect 2-3 devices to charge simultaneously. The only downside is its heavy weight.

I don't know what happened with mine, even though it didn't fall, I didn't leave it in heat, etc. It swelled up and never worked again, of course. I recycled it straight away before it exploded. Also, charging on an iPhone is a nightmare, it kept disconnecting all the time

As soon as you hold it in your hands, you realize that it is a quality and well-made device. A bit heavy for everyday use, although logically you don't need 20000mAh for every day. I will also order a neoprene case for mobile phones so that I can put it inside when I want to take it with me in my backpack. Its main disadvantage is the slow charging speed, both for itself and for the devices it will charge. Satisfied, I would buy it again, as well as from the same brand, but perhaps I would prefer a model that charges faster.

Simply top. It has cables on it for EVERYTHING! It has a bit of weight but it is by far the best product in its category

It is a bit heavier than you expect, It has built-in charging cables which makes it unbeatable
