HomeKit Australia has a run of enquiries on Apple's new MagSafe charging technology, since the release of the new iPhone 12 series.
It is worthwhile understanding, however, where this technology is really useful and where it may be not.
Firstly, only original Apple MagSafe chargers will produce a full 15w charge. Other brands can only produce up to a maximum 9.5w.
Next, if you have an iPhone 12, throw away your previous magnetic car charger (unless it has some sort of holding frame). My magnetic car charger would support the weight of my old iPhone X and charge at the same time. It's never going to hold my iPhone 12 Pro, with the iPhone 12 series not having the magnetic back of previous iPhone models.
Unlike the recent iPhone models, the iPhone 12 series has magnets positioned inside the case housing at specific points - you would have all seen the dotted circle. Unless your magnetic charger has corresponding magnet points, you will only get a maximum 7.5w charge and in my case the phone will simply fall off the magnetic car charger.
You will continue to get wireless charging at 7.5w from Qi-compatible tabletop chargers, provided they output 7.5w or more. Many Qi chargers only output at 4 or 5w, so charging can be slow.
The MagSafe magnet array is made up of thin, low-powered magnets, requiring any user to have an exact match. If you'd like to experiment with MagSafe you can even buy the magnet arrays from enterprising Asian suppliers.
It's for this reason you should be careful in selecting MagSage accessories especially MagSafe iPhone 12 cases. Some suppliers simply stick these readily available magnets to the inside of the case, where they can be easily damaged.
A good case should have the magnet array either recessed into the case or physically built into the case itself. Ensure you check this prior to purchase.
Remember that MagSafe products including a MagSafe charger does not include the actual AC charging unit, so you will need to purchase this separately.
Once again, pay careful attention as the AC charger must be a minimum 20w and dsupport the Power Delivery (PD) 3.0 standard at 9V 2.22A, the specifications you require to fully utilise Apple's MagSafe 15w charging technology. Many chargers will not deliver according to the PD 3.0 standard and you will not get a full 15w charge, no matter whose MagSafe charger you buy.
The latest details from Apple suggest that iPhone 12 Mini will only charge at 12w with MagSafe.
A quick note .... when purchasing a MagSafe charger, look out for chargers that will also charge your Apple Watch. Not all of the MagSafe chargers on the market can do this.
You will read ample stories of the MagSafe magnets affecting swipe cards and the like so do be careful about storage of programmable magnetic cards such as magnetic hotel room keys .... best not to purchase a magnetic MagSafe wallet and then use this to store such items.
So, is MagSage all that it is cracked up to be?
Well yes and no.
I'm certainly going to make full use of the technology and HomeKit Australia is about to receive stock of their patented MagSafe chargers and then follow up with the world's first MagSafe car charger.
But remember, charging by cable is much faster, just possibly not as convenient. If you need maximum power charge, as fast as possible, use a Lightning cable and AC or fast car charger.
I've typically followed this process and continue to follow it with my iPhone 12 Pro - which I love. We also have 10w Qi chargers dotted around the home and office, and we continue to use these when we are not chasing that fast charge quickly.
Added to this we can very likely see Apple evolve the MagSafe charger - improving speeds and adding products and utility. The great news is that Apple are full ahead with the technology so it will get bigger and better, so it's worthwhile getting onboard from the outset.
