Bests & Worsts Reviews from Amazon

I see a lot of complaints that come from a place of misunderstanding about how this actually works. It's a great charger just like you'd expect from Samsung. No, it's not "slow" or a scam. Here's the thing: the power output you're getting depends on the current percentage of battery you have left. You won't get the full 45w of charging ALL THE TIME and this is by design. At 0-50% or so you'll get *up to* 45w, sometimes closer to the area of 35w. After that, the charger trickles the power down to protect the battery from overcharging and overheating which makes it appear "slower." The closer you get to 100% full, the less power it will output. So if you plug it in when the battery is already at 75% you'll start out at about 20w and bypass the 45w totally. In this, you will only see the benefit on short charges when your battery is really low and this charger excels in this context. I can charge my battery from 20% to around 60% in 20 minutes. The system will also notify you in the pull-down bar if you're using it on a supported Samsung device. I'm using it on my Note 10 Plus and the charger is recognized as "Super Fast Charging 2.0." It helps if you understand exactly what you're buying and part of the confusion can be blamed on Samsung for how they marketed it to a general public who doesn't understand these things. They just say "WOW! 45w!" and that's what people believe. It's true, just not in the way you'd expect. The 45w is conditional. With that explanation out of the way, I would definitely recommend this charger if your device supports it. There's no downside. You can only gain advantage by boosting charging output at low percentages over the standard 25w charger. Yes, this is a genuine Samsung charger made in Vietnam with retail packaging and not a bootleg. I wouldn't trust anything else out there. Go for it if you can spare the extra cash. I feel that it was worth it.
