Quite good and with the power it claims. It can charge 2 phones simultaneously. Be careful if you have a deep cigarette lighter socket in the car, it may not reach all the way and make a poor connection!

It has amazing quality and fast charging, but the earbuds that fit into the port are a bit loose and fall out. The voltage is correct at +-0.2 volts as it shows. The problem is probably with my car's port, which is shallow, but for the money I paid, they should have anticipated this, which is why I give it 3 stars. It's a shame because I had to wedge it in with a plastic piece to keep it in place.

I have had it for two months and after 3500 kilometers on various trips, I found that it is reliable with no problems at all. For now, I am very satisfied.

As quality very good and charges mobile quite fast. In my machine fits very well. In the car is also fine in application. In fiat doblo at work does not fit properly.

The gadget does what it says, but it doesn't fit at all in a Nissan Almera N16 2005, it's a car receiver issue

Excellent! Perfect fit on a 2016 Yaris, it doesn't protrude much like others, charges very quickly compared to others I've had in the past, the voltage indicator is clear and useful. I have paired it with USB cables from the same company. I am very satisfied.

Necessary for every car, it shows you the battery level. I have bought 2-3 for the family cars.

It is worth every penny. It charges quickly (with the original phone cable), without overheating. A useful feature is the battery power indicator.

It fit perfectly in the lighter socket.
The good thing is that it doesn't overheat excessively like I have heard about similar products.
One of the positives is definitely the battery voltage indicator.

In the FIat Punto that I installed it, it does not have a good fit, resulting in it coming out of its position.

Good quality, it looks sturdy and durable. It fits perfectly in my car. The only downside is that it does not support fast charging on my Redmi Note 8 Pro, I imagine the same will apply to other mobile phones.

Very good build quality. I don't know if it charges the phone quickly, but every time I connected it for a 15-minute drive, the battery level increased without indicating slow charging. It requires a little attention when placing the lighter, as it tends to move and turn off. Regarding the voltmeter, there is a slight deviation. With 3 multimeters that I have checked, it does not have the same accuracy. For example, the multimeter shows 12.5v, this will show 12.4. It simply gives you an idea that the car battery has sufficient voltage. However, the measurement may not be objective from this point as cables, fuses, etc. may interfere. What I liked the most is that the voltmeter screen does not shine excessively, so it does not distract you while driving at night. For use in Opel Astra G. I hope I helped.

Charges 2 modern mobile phones easily. The only small disadvantage is that it has small prongs and does not fit well in my own lighter, so I put a piece of paper. Otherwise, it's fine.

It does not fit well in the cigarette lighter port and the LED indicator works intermittently. Otherwise, it seems to be a quality construction. However, I think I would look for another option with better fit.
