The transparent cover is a good idea...
Generally short fit on the lighter, so-so... As a build, it's ok..
Flashy packaging with only the charger inside... Not even instructions or anything....
I mainly got it for fast charging qc3.0 18w which it supposedly says it does...
At first glance...
I tried the orange usb-a with usb-c cable on 2 xiaomi phones but I did NOT see the fast charging message appear on the phone....
If that's the case, it will be a big disappointment and of course I'll probably return it for something else... We'll see...
I'm just holding off to try the usb-c to usb-c port... To see if anything changes... I'll also wait for the phone's battery to drop more in case that's the issue and I'll reconsider the review... In short, I'll come back...

I'm also listing its specs here..

Update.
Even though I finally had a 5A cable connected, it didn't show fast charging.
I finally tried another cable and the fast charging message appeared...
So probably the cable was to blame, which is strange because with another fast charger it charged quickly as usual... If I remember correctly...
So this is probably a fast charger... And as it seems, I'll probably keep it....

Note... It also has a blue/purple LED..

Update..
After using it for a few days, although it shows the fast charging message, it doesn't seem to output enough amps to charge the phone quickly...
I'll monitor it and connect a meter between the usb output and the cable to see exactly what voltage and amps it gives, in case the phone doesn't show correct readings...
On the phone basically I only see amps, not voltage...
Charging, despite the fast charging message, doesn't seem fast at all... It looks like a simple charger...
Let's see.... I'll try another cable again maybe...
I wouldn't say I'm satisfied though...
But health...
That's all...
See you again...

update..
I finally connected a usb energy meter to it and indeed saw that it raises the voltage from 5v to 9v with enough amps, specifically 2A which makes 18w, which is the maximum my phone supports...
So fast charging was verified...
In practice, it didn't seem to charge quickly from what I saw on the phone and from experience with other chargers..

Update..
With one device at a time on one of the 2 usb ports, it does fast charging...
If you connect 2 devices for fast charging, then it works as a regular 2A charger and does not do fast charging..

But ok... What can you do.. Health.. Now we've got the charger and hope it does its job...

Recently I also tried a power delivery 15w device and fast charging worked fine..
