These are the checks you should carry out to determine if the charger or wall outlet is faulty.Īnd if the charger is bad, then it’s best you replace the Macbook Air charger cable by making an order on Amazon or eBay. Check if the adaptor’s color has changed or looks burnt.Determine if the adaptor is giving a burnt smell.Whether there are visible cuts on the charging cable.The adaptor may have been properly connected, however, if there are physical signs of wears on the wire cable or power cord, then it could also cause charging problems.

That being said, here’s how to test the Macbook charger: Remove the Device’s Charger It’s no use getting a fix when you’re unsure if the charger is faulty to begin with. The first thing you need to do is to test the Macbook charger to ascertain if it has faults. There will be no harm done for people that mix up these USB chargers, but mixing the up will get disappointing charging rates.The major causes of a Macbook not charging are: They will all at least fall back to providing something for power. Well, they are incompatible for providing more than 5, 7.5, 12, or maybe 15 watts of power. It also doesn't help when they use such similar names for incompatible charging systems. What Apple calls "fast charge" is just USB-PD by another name. I do wish USB chargers would put on the charger what charging protocol they use, and do so using the same names as everyone else. A $30, $40, or $50 charger removes the slow charging concern for the laptop, but not for the phone. A quality 20 watt USB-PD charger can be had for $20, and should provide enough power to avoid running the battery dead on a MacBook Air unless it's run really hard, and will also be a spare 7.5 watt charger for your phone. If so, and it doesn't cost too much, then getting one might be a wise investment. I don't know if a 20 or 30 watt charger exists that supports both VOOC and USB-PD. The number of them rated for more than 12 watts though is just two. The chances of me not having any means of charging my newest laptop is near zero now as I have multitude of USB chargers on hand. The problem we will find today is that not all USB chargers are equal. Today this isn't near the problem as then since USB charging is the norm, chargers are less expensive now and very interchangeable. I keep a spare laptop charger on hand since then. Years ago I found myself in a spot with a much needed laptop running low on battery and no charger for it in the vicinity. That's assuming you didn't do what I did that forced me to charge my 60 watt laptop from a 12 watt phone charger, temporarily misplace two laptop chargers. One last thing I'll say I'm at least minimally certain about is that it would be wise of you to invest in a spare USB power brick better suited for powering your laptop. I'm quite certain my answer is too late to help with your dilemma of avoiding a dead battery, but will hopefully help you or someone else in the future. The transfer of power would stop before damage is done. I'm most certain that this will not damage either the charger or the laptop, both have enough "smarts" in them to not do anything that will damage them. I'm quite certain it will charge the laptop while it is powered down or sleeping. I'm quite certain that your MacBook Air will take power from this charger to at least extend the battery life while in use, perhaps even have some power to spare for charging. The 7.5 watts you will get from your phone charger is 1/4 what you would get from the Apple charger that came with the laptop. The supported USB-BC charging rate from this charger is likely 5 volts at 1.5 amps.

These chargers will fall back to USB-BC charging for backward compatibility with older One Plus phones. A bit of research tells me that this charger is likely using a charger protocol called VOOC or Dash Charge. This is because 5 volts at 4 amps is not a valid USB-PD power profile.

I've discovered that in a situation like yours my MacBook Pro will charge slowly from a 12 watt iPhone power supply that uses USB-BC and Apple's BrickID for charging.īased on what I know from USB-PD I believe your One Plus charger does not support USB-PD. Apple laptops with USB-C, and the power supplies that come with them, will use USB-PD for charging.
