There can be several issues that could be preventing your MacBook Pro from starting up normally.
#BACKUP POWER SUPPLY FOR MACBOOK PRO SOFTWARE#
For instance, it could be due to a faulty charging cable, a damaged power adapter or a software or hardware problem with the device. Well, if your MacBook Pro would not turn on, then it could be due to more than one reason. So, What Could Be the Reason Behind the Issue? Whether your MacBook Pro refuses to turn on or seems to get stuck at the Apple logo, these viable solutions can help you in fixing your ill-functioning device. But fret not this is where our pro tips come in handy. While Apple’s notebook excels in delivering top-notch performance, it also has a history of being embroiled in stubborn issues. In addition to being $20 less than Apple’s 61W option and $30 less than the 87W charger, you also get another 12W of output from two standard USB ports with this $50 Aukey charger ($38 through this weekend).Nothing can be more terrible than finding your MacBook Pro dead or being stuck with a black screen. Conclusionįor 12-inch MacBook or 13-inch MacBook Pro users, I think Aukey’s 60W USB-C charger & dual port USB is a great alternative to Apple’s charger, whether that’s as a replacement or as a backup option. For 15-inch MacBook Pro owners, if you’re not a power-user, it’s also likely a solid choice. For those regularly working with 4K video, doing 3D modeling and rendering, crunching big data sets, or other similar intense tasks, the 87W charger should offer greater output with the 15-inch MacBook Pro models than shown in my testing, and be the best fit. I’m by no means a power user, but my MacBook still handles a decent workload. Variables and considerationsĪs with results from tests like this go, your mileage may vary. But of course, after an hour and a half the 87W charger offered 4% more battery, meaning the average output was a bit higher than the 60W charger, but was still lower than I expected.īoth the 60W and 87W chargers were outputting around 40W of juice after 90 minutes. The Aukey 60W charger put out around the same 57W, for the most part keeping up with the 87W power adapter. Of course this number isn’t static, but it was interesting to see my 15-inch MacBook Pro requesting less than 60W while in use. In my testing, Apple’s 87W charger put out around 57W. When plugging in with battery at 10% here’s a look at the power output of the two chargers: After an hour and a half, the 87W charger added 76% battery while the 60W charger added 72%. The results below are the average of two tests for both the Aukey 60W charger and Apple 87W charger.Īs you can see, the 87W charger filled up my 15-inch MacBook Pro battery more quickly than the 60W charger, but not by very much. As shown below, in my testing, even the 87W Apple charger and original Apple USB-C cable didn’t output over 60W. This power meter is limited to measuring up to 65W, but it was only used to spot check output. I used Satechi’s USB-C Power Meter to measure output and started the clock with the battery at 10% for all tests. That includes eleven open apps, Safari with 4-6 tabs open at a time, TweetDeck with streaming on, and brightness set to 75%. Because charging times aren’t as important when you’re not using your MacBook, all tests were done during normal work days here at 9to5Mac on my 2016 15-inch MacBook Pro running macOS High Sierra.
