Bests & Worsts Reviews from Amazon

Wish it was included in the box, but other than that, this charger is great. I see a lot of people complaining that it doesn't charge at 25w, and they are using batter apps to justify their claims. Obviously, these people don't understand how chargers work. You will not got 25w speed 100% of the time. The charger slows down to protect your battery. Also, apps are completely innacurate anyways. For the charger nerds like me, this is actually a pretty capable device. It supports power delivery at 5v 3a, and at 9v 2.25a. Also it's a PPS meaning it can actively adjust the charge rate. It supports 3.3-5.9v at 3a, and 3.3-11v at 2.25a. In practice, and with real, physical, electrical measurements that aren't from an app, I can confirm these rated specifications. It is just a 25w charger, so you won't be charging a big hefty laptop at the speed of light or anything, but this brick will charge your samsung phone with "Super Fast Charging", and will charge the majority of normal consumer phones and tablets with ease. - Written while Super Fast Charging my S21 Ultra :)
