Review on ANISAM 3 In 1 Magnetic Charging Cable (3 Pack by Ronald Wheeler

I just received it today and what I love about it is that you can leave tips on your device to keep dust out and you can just either the charger and plug pick it up without looking as it locks into place automatically. What I don't like is that it doesn't charge my MacBook. There is a notification that it's charging, but when I click on the battery it says the device isn't charging. What worries me is the charging speed, I'll be using it for my iPad and iPhone but I'm worried it won't charge it fast or heat up my devices. I'll post a follow-up review once I have more time with it.
