For the Tracer 9 it works flawlessly and fits perfectly. I charge an iPhone 14 Pro at the same time while using maps and an Insta360 X5 while it records in 8K. The phone charges normally while the camera discharges slowly. Of course, I was charging it via USB-A, while perhaps with Type-C both devices would charge normally.

I ordered two and both products arrived defective.
I did not expect this from a product with such good reviews.
I tried it on different cars, cables, and devices.
They do not charge.
I couldn't believe that both would have an issue.
I said, since that's the case, I'll open them up to see inside.
What I found is that they are very poorly made and the problem is that they do not complete the circuit.
That is, the negative that should touch the USB port so that the current flows simply does not touch it at all.
I uploaded a photo of what I mean.
I won't bother returning them.
Since I fixed them myself, now they might do the job.
Perhaps expected for their price and construction

It does its job, but the photo is a bit exaggerated. It is a cheap plastic construction, don't expect it to be sturdy. However, I repeat, it does its job just fine

Very good car charger. It doesn't have the looseness that similar chargers usually have in the cigarette lighter socket and it sits firmly. As long as I've used it, it has worked perfectly, especially compared to previous chargers I had tried which were useless. I believe it is worth its money.

4 stars because, as others have said, it went in and got stuck in the lighter socket. Since I want it there permanently anyway, it doesn't bother me much, but if it breaks for example and I want to remove it, a battle is expected.

Note, when you put it in the socket, it takes about half a minute to work, probably because its capacitors are charging.

It does its job just fine, it's just that once it's plugged into the car's lighter it takes a bit of effort to remove it again, nothing prohibitive though

Excellent product! It really offers very fast charging in the car — we're not just talking about fast charge, but ultra fast charge. It charges the phone in no time.

I tried it on 2 cars, on one it didn't make contact, on the other it works but it needs to be rotated millimeter by millimeter until it finds the right spot. When it works, a light turns on, fortunately.

The stupid thing got stuck on my car, it took me half an hour to remove it. 6 euros is not worth it for how much it annoyed me first thing in the morning

As a device, it does what it promises and is worth the money it costs! The fit in the car cigarette lighter socket is a lottery... In a Fiat Sedici it goes in and out very loosely, in a Peugeot 107 I struggled to remove it... However, in charging it is very fast!

It just DOES NOT go all the way into the lighter socket NO MATTER WHAT. As a result, of course, it doesn't work... Tried in two cars. I almost broke the car lighter socket! Terrible!
Car: KIA Sportage 2025

Fits perfectly in a Renault Clio 4 (2015). I have a Nothing Phone 2A, which supports 45W charging, and with the phone's cable I get excellent charging speed, as if charging from a wall socket. Very sturdy construction, nothing like some Chinese knock-offs

It does not fit properly in the port, resulting in it not working. Even though I pushed it deep inside, it still did not function and then it was difficult to remove it again. Prefer something else, something better.

Very fast charger, value for money, with a dual port for USB or type C. The only downside, which might also be due to my vehicle's lighter socket, is that it doesn't fit well and you have to find the right spot for it to catch and not just push it all the way in.

2 stars minus because on S24 Ultra it doesn't even do fast charge, surprisingly it charges faster on USB A than on C. On the previous Xiaomi T13 Pro it was flying, measurement with Ampere over 4000mA.

Honest and small charger! Charges relatively quickly…
don't expect to get fast charging like at home!

The best charger for devices in its category! Very fast charging on iPhone as well as on the power bank I have tried! I will buy a second one for the trunk space!

Bad charger and I explain. Practical the small size yes, but when I plug in both ports to charge, for a few seconds it cuts off the charging from the other port and vice versa, until a few minutes pass for it to recover. For me, it's a no.

Good! Indeed fast. Yes, as others say, it fits tightly and depending on the console around the lighter, you might never take it out of there again... Remove the plastic wrap around it before you put it in...

The worst thing I have ever bought in my life. I mean it really upset me and made me angry. The Seat Ibiza wouldn't fit no matter what, and I said since the comments say it fits with difficulty, but then it doesn't move and such, mine didn't work no matter how much I tried to put it in, at some point it just wouldn't go in anymore. Again nothing. The good thing now is that it barely comes out, it will break my dashboard if I force it any more. Honestly, if I lost 9 euros, I wouldn't be as upset as I am about this thing. It really drove me out of my mind

In Yaris, at least it fits perfectly. With the corresponding cable, it charges my phone extremely quickly

It does its job well, the only issue in my case (in a Ford Fiesta) is that it fits very tightly and because it is small, you can't easily remove it

So many positive reviews, but it doesn't fit in a 2001 Ford Focus for any reason in either of the 2 positions it has. What a shame.

I got it for the quick charge as I had another one which did not fit well and I expected this one not to fit well either... but it turned out better than I expected... 5/5 easily

It sits perfectly in the car socket and doesn't move at all. The charging speed is more than satisfactory (for my case). Its low profile makes it almost invisible

It fits quite well in an old Fiat Punto. It takes a little bit of turning back and forth to make contact at first, but afterwards it works perfectly fine and doesn't have any issues like slipping out of place or stopping charging on bumps, etc. For its price, it is very good, just like any other Baseus product I have tried so far.

In Opel Astra h GTC (2008), it does not fit well, you have to turn it and in specific positions the charger light comes on and it works. When you find the right position that works, you have to carefully insert the USB cable because the charger moves. If you manage to do it, then the charging on the mobile phone works normally.

It's awesome! It applies so well that you wonder if it got stuck haha!! Very good build quality, fast charging, discreet design!! Good price!

It does what it says and works well.
On the Google Pixel 6A, which is a bit difficult with quick charge, it worked perfectly.
And with all mobile phones, that is, iPhone, Samsung, etc. I have tried it with many.
Very satisfied here and for a year now that I have it.

The charger is good, I liked its construction, it charges satisfactorily, but after a few months it suddenly stopped working.
