It includes a car charger and the original cable and charges Huawei phones at 40 watts if they support it. If your phone does not support at least 40w charging and it is not a HUAWEI phone, then it is not worth it because you can do the same job with a charger that costs less than half the price. I bought it for 21€.

The charger is very good, super fast charge as it says, charges like a wall socket on the Huawei P40 Pro. It's worth it for me with 1000

For Huawei devices, the best thing is that it charges the Mate 40 Pro and Nova 9 like a charm. Of course, it's a bit expensive, but if you have a Huawei phone, it's worth it. Otherwise, there are cheaper options available, like Xiaomi, which are also very good

I was looking for a car charger for super fast charging as I own the Huawei P30 Pro. So, the super fast charger works perfectly. I don't know how it will work with other devices that require less power and I don't really care. If you are simply looking for a car charger, you can find some for 8 euros, which are gems (I had seen one from Xiaomi, actually very powerful at 8 with 37W). If you are looking for a super fast charger and it supports the power and your device is worth the purchase! For Huawei owners, it's a one-way street.
As for the negatives, it is a bit long, so if it was in a different position, the base would not be practical at all.
