Favorite charger
Size: 10FT, Color: Yellow
This is my 3rd purchase of this brand of charger (different colors). The yellow color is just as pictured. These chargers always fit flawlessly with my iphone15 pro. The charger provides a fast and lasting charge for my phone, iPad, or anything else I connect it to. I love the bright color options. I highly recommend this charger because they are durable and provide a quick, long lasting charge.

Perfect charger
Size: 10FT, Color: White
Very impressed with how quickly the charger works. The longer cable has made it easier to use the phone while charging and sitting on the couch. No issues with the cable getting tangled or fraying like I have had with others, or pinching and breaking the connection.

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.
