I just found the MAXOAK 36,000mAh: (Note the statement by the end: "newer MacBooks that use USB-C charging are not supported at this time.") Also: (Statement at the end again: "Unfortunately, it is not compatible with Macbooks using USB Type-C connectors or 17" MacBooks.") It is not cheap (136 USD, or a bit cheaper: 126 USD), but as my Mac will soon pass its 2nd year, such a "beast of a battery pack" will come in handy when the built-in battery begins to age. Well, the Apple-guy turned out to be wrong in saying that there are no external batteries for the Mac 13" 2014. There does exist an alternative solution, though: "harmonizing" a usb male and a MagSafe plug via soldering. Even the cheapest option, Chugplug, is 130 USD. Googling a bit, I found some solutions to the problem of charging a MacBook from an exterinal battery, but the price of those models that are capable of charging a laptop, begin from well above 100 USD. I inquired at Xtorm and Gecko Support team, where I was informed that this power bank was designed to charge Macbooks through USB C, and if my Mac does not have a USB C input, I can not use this model to charge it. However, it escaped my notice that it only charges MacBook Retina. I've actually done a lot of research into external battery packs, finding about 3 or 4 models that have the capability to charge Macintosh notebooks, and the AL450 USB-C Power Bank was one of them. It eventually became clear for me that they were so much willing to take the item back without a word because this power bank was not actually compatible with my Mac Air 13". They also told me that they did not know of any battery pack that can charge Macs (except for this one which can only charge the MacBook Retina equipped with USB-C). If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.I eventually took your advice and took back the power bank to the shop (iStyle, the official Apple dealer here, in Hungary), where I received a total refund.
Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months recharge your battery to 50% or so every six months roughly if being stored away. If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F).
for free in shop full diagnostic and likely parts replacement ? If same and incapable of powering up., then:Ĭontact Apple for an appt.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
Release all the keys and the power button at the same time.On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.Did you shut down your computer "over a month ago" on less than 20% or so of power? If so that extremely harsh on the lithium battery, since self-discharge occurs naturally and storing it away low is very hard on same.
