Cool design
Finally I don't have to carry several power banks with different output types all the time. :D This is smallest power bank I've seen with same capacity. The LED display is also pretty cool. I probably will find a plastic case for it since the surface is a little susceptible to grease.

Slow Charging Power but Really Nice for Travel
It is not the fastest charger but I knew that when purchasing it. What I was interested in was the various built in cables and the price. It is a good price and the convenience of having all possible charging cables built in is really nice. I do wish everything would just have USBC charging now but if you need to have an emergency charger without worrying about whether you have the right charging cable this is a good option. It is a nice compact size as well.

Ineffective charger
KLL Power Bank with Built in Cables, 10000mAh Slim Portable Charger, was a good idea, but was very ineffective because the charge lasted only a few minutes & recharged about 15-20% for our IPHONES .

It's the best one compare to what few other I had before
Fast charger

Could have less capacity than described but overall not bad
I used it to charge an iPhone 13 Pro Max from 47% to 100%. The iPhone 13 Pro Max has 16.75Wh which means the net energy input was around 8.88Wh. Assuming 75% charging efficiency (average battery charging efficiency), total energy used was 11.84Wh. The battery bank dropped from 100% to 59%. The capacity of the battery bank is estimated to be 11.84 / 0.41 = 28.9Wh which is lower than 37Wh described but close to it. Assumptions used could have errors though. Overall it's good and convenient.

Not that tiny
I don't know how big the hand model's hand is up at the top of the page, but it's huge, because this is not a small charger. It's nice, but it's not small. It's wider than my hand, and I don't have little hands. The good: this works. It's not high speed (according to my phone), but it's fast enough. I don't have any Apple products, so I can't swear all the cables work, but the USB C & micro USB work just fine. I love that the cables are integrated. I also like the digital display showing the percentage left. The bad: it collects fingerprints very easily. It's not as small as the pictures try to make it look, but it will fit in a decent sized pocket or a purse/bag. It's not fast charging. (None of these are really bad traits, just not great.) There isn't an integrated cable to charge this device. The weird: I tried to get a picture of this, but it's a little blurry. The charging port is USB-C. The instructions say to charge with the included cable. The included cable is micro USB. I have a million USB cables of every kind, so I didn't need a new cable, but the fact that something so basic could have been missed by quality control kind of worries me. I knocked off a star because at $32, it's a little pricey for a 10,000 mah powerbank, though it does have the included cables. Also, I am worried about the quality control since the included cable to charge this unit doesn't fit into the charging port. But this is solidly good. ***ETA*** I didn't realize there were 2 ways to charge this! There's a hidden micro USB on the side and a USB C on the end with the other holes. So the included charging cable actually works. I changed this to 5 stars because even though this is still a little pricey, I'm not worried about the quality now. Let's call this 4.6 stars. :)

Convenient
I don't usually mess with portable chargers any more, but I saw this and liked the size of it as well as the fact that the charging cables are included. That was a big plus. It arrived about 3/4th already charged so it didn't take very long to fully charge it. I like that you can easily see how much battery life is left. The size fits in my back pocket easily. The cables work well - or at least the ones I have used. I don't have any Apple products nor did I know what to do with the USB one yet. However, I do like having the Apple one, too because there have been times when my daughter or a friend has needed one. I took it with me for a recent day of tailgating. I started charging my phone about half way through the day when my phone was at about 40% I found it to be a bit slow. It seemed like it would take a couple of minutes for my phone to go up 1%. After 45 minutes my phone had gone up to 68%. I'm used to faster charging. It wasn't terrible and I can definitely live with it. I used it a couple of more times for shorter periods of time on that same day. By the end of the day, the charger was down to 60% which seems like less than other chargers I've used. Again, I can live with that. I do like it and I see that it will be helpful.
