Solid charger for the price
Picked this up as a backup for MacBook Air and honestly its been working great. It is enough to fast charge the laptop even while Im using it which is all I really needed. Also tried it on my iPhone and it works well. Easy to connect, no need to setup anything

Durable - Works for my Mac and my kids’ computers
My kids are constantly losing my MacBook charger and they’re expensive! So on Prime Day I treated myself and bought this charger - which I told them they’re never ever allowed to touch under any circumstances.
The brick is pretty big compared to what I’m used to. The cord length is fine and it charges my MacBook quickly just like I wanted it to! I was really pleasantly surprised by how legit this charger is for the price, given how costly they can be. It seems really sturdy.
Turns out, this charger also fits the Chromebooks that all 3 of my kids use for school, and whose chargers are always missing. So “my” charger is once again a shared charger. But it gets all 3 Chromebooks and my laptop fully charged in a night. Nice, easy, durable product for a great price.

Sunveza MacBook Pro Charger: A Game-Changer on a Budget!
Man, where was this Sunveza charger when I first got my MacBook Pro? I'm the type who'd forget my head if it wasn't attached, and yup, I did it – forgot my charger on my first day bringing the new MacBook to the office. Enter Sunveza with its high-efficiency and surprisingly affordable solution.
First off, this thing charges FAST. Talking about going 0 to 80% in what feels like a blink. And the compatibility? Spot on. Whether you're rocking a MacBook Pro, Air, or even an iPad, this charger's got you. Plus, the multiple security features? A major bonus. Peace of mind knowing my gadgets are safe from overcharging or short-circuits.
Now, if we're comparing aesthetics, yeah, it doesn't have that Apple "heft." But honestly, does that matter? It's like comparing a sports car by the weight of its keys. What matters is performance, and Sunveza delivers.
I stumbled upon this gem after a less-than-stellar experience with a pricey off-brand from Target. Sunveza's charger is just the right size, doesn't sag from the outlet, and feels just right. The only tiny hiccup? The cable can be a smidge finicky sometimes, needing a gentle push to snugly fit. But considering the overall value and the fact that I could always grab a new cable if needed, it's a minor gripe.
In short, if you're in the market for a MacBook charger that won't break the bank and performs like a champ, Sunveza's got your back. Highly recommend! 🌟🌟🌟🌟🌟
EDIT: Wow okay... so things were working great for several months but then I started having issues with this charger and it would intermittently start and stop charging. The charger block itself would also get painfully hot to the touch. I had been using this product for less than a year when I started having these issues. I tested this out with other devices and outlets and witnessed the same behavior. I also took my MacBook to the Apple Store and they informed me that my battery was damaged, likely because of this charger. In light of this, I can no longer recommend the Sunveza charger.
