There are other USB-C battery packs like Ankers which will charge the MacBook but only at 5V and it barely keeps up with normal use. There is a long discussion there about using the 87W with the iPad, but I haven't followed it as I dont have an iPad.īecause it is related you might be interested in this RavPower battery as it is (AFAIK) the only USB-PD compliant battery pack and will charge my MacBook at 15Vx2A=30W.
I asked the same question on another forum However both are charging it at 30W, so the rate of power input is the same, so it doesn't charge any faster.īecause of the lingering doubts I contacted Apple Support and and was reassured that it is fine and the 87W is now my main charger, the 29W is what I take out of the house. I wouldn't have had any doubts except that I have a Satechi USB-C power meter and it showed the 87W charges at 20V and the 29W at 15V (consistent with the voltages on the chargers).

Since then, 13 MacBook, 18 MacBook Air laptops and 48 MacBook Pro laptops have been. Since the first MacBook came out in 2006, Apple has introduced 10 different chargers. I have a 12" MacBook but saw a 15 inch MBP in my future so when I wanted a spare charger I bought the 87W one for the MBP to use with my MB.Īs the other replies say the Apple documentation is very clear that you can use any Apple USB-C charger, in fact Apple say you can any brand USB-C charger which is USB-PD compliant. According to Apple: 'You can use a higher-power adapter, but you cannot use a lower-power adapter without potential operating problems.' Not all MacBooks use the same charger. Similarly, can we use 87W charger on the ipad pro? THey are happy with 29W USB-C charger and new USB-C -> lightning cable on ipad pro. I read reviews, of ipad pro owners complaining that the standard 12W USB-A => lightning charger takes 5 hours to fully charge. Is 87W USB-C safe for my 12 inch macbook? My 12 inch macbook uses a 29W USB-C charger.
