USB-C to USB Adapter - Previous Gallery Image USB-C to USB Adapter - Next Gallery Image USB-C to USB Adapter. RM 99.00 All Colors + USB-C Digital AV Multiport Adapter - Previous Gallery Image USB-C Digital AV Multiport Adapter - Next Gallery Image USB-C Digital AV Multiport Adapter.The MagSafe Duo charger, meanwhile, offers up to a slightly lower 14W of charging when paired with a 27W or higher brick, so long as that brick supports 9V/3A. You get 11W of charging by pairing it with a 20W power brick that supports 9V/2.22A, and Apple says you need “at least 15W (5V/3A or 9V/1.67A)” for the Duo to charge two devices simultaneously. If you’re charging an iPhone 12 mini, the maximum charge is capped at 12W with the Duo.
Charging Li-Ion batteries can be a dangerous pastime if not done correctly. 'Charger' is used loosely since both the USB-C ‘chargers’ and the ‘MagSafe Charger’ are effectively both power supplies utilising Type-C.Battery management and charging electronics are within the iPhone itself, which is a wise move. It supports proprietary wireless charging from Apple in order to sneak some extra power across the gap. It's compatible with the Qi wireless charging protocol. Apple's MagSafe Charger connects to a USB-C charger via a USB-C cable/connector and provides wireless charging capability. Leonis Magnetic USB-C Power Adapter The Leonis Magnetic adapter is an affordable charging set that meets the standards for USB-C.Plenty of devices have very specific requirements for the hardware you need to use to get the fastest charging speeds, so it’s hard to blame Apple too much here. There’s data, as well as power, transferred between the MagSafe and the iPhone 12. It removes one of the main issues with wireless charging, poor alignment of the coils causing poor power transfer efficiency. This ensures the wireless charging coil is placed parallel and centred with the opposing coil within the iPhone.Fair play to Apple. But enough about that, back to the MagSafe Charger.As you expect, MagSafe is a nicely designed wireless charger which, if you have the latest iPhone 12, holds itself in place on the rear of the phone via integrated magnetics. The advertised voltages depend on the power available from the charger. Other info changes hands between the charger and device, ACK’s, vendor data etc but that's for another day.USB PD 2.0 also allows for a number of different voltages and current limits to be advertised to the connected device: 5/9/15/20V, 2/3/5Amp etc. These control signals allow a charger to advertise its capabilities to a device and the device to tell the charger what it will accept. This 2.22Amps should be regarded as the minimum current that a compatible charger should offer at 9V.All USB-C cables, according to the USB-C spec should be able to handle at least 3Amps. A final charger offering more than 45Watts will advertise 5V, 9V, 15V and 20V.In the case of a MagSafe Charger, it is looking for 9V at 2.22Amps which works out to be 9*2.22=20Watts. Another charger offering more than 27Watts will advertise 5V, 9V and 15V. One charger offering more than 15Watts will advertise 5V and 9V. For example, a charger offering 9V and 3Amps would be offering 27Watts (9x3=27). Control tab for macWhich means there are additional features baked-into USB PD 3.0, which can offer benefits: The 2018 MacBook Pro ‘talks’ USB PD 3.0.USB PD 2.0 will work with a USB PD 3.0 charger since USB PD 3.0 is backwards compatible. These data packets were only relating to USB Power Delivery (USB PD) spec version 2.0, rather than USB PD 3.0.Is there a problem with this? No, although I expect to see Apple switch to USB PD 3.0 across the board in the future so they can leverage the increased functionality within the USB PD 3.0 spec. C-Auth (USB-C Authentication). This means if the internal device charging electronics work most efficiently (read: less heat generated) at 4.4V then the device can request 4.4V. The device current limit can also be negotiated in 50mA steps. This allows the charger and device to negotiate a voltage between 3.3V and 21V in 20mV steps. Safe Adapter For Usb C Full Charging RunThankfully the DataGraph for MacOS app helped dealing with huge CSV files. Each of the tests runs for at least 4hrs and create a CSV file with close to 2,000,000 rows! Way in excess of the amount of data which Apple Numbers and Microsoft Excel can import. This takes many hours of streaming video, sound and flashlight!Once the battery is flat, I charge it and record various parameters during the full charging run from zero to 100%. For example, an Apple device may only authenticate with Apple chargers or approved OEM chargers.The data was collected using a commonly used USB PD Analyser which measures Vbus, Vconn, CC1 and CC2 voltage and current as well as capturing and decoding the USB PD data packets between the USB-C charger and MagSafe Charger.I haven't published the data packets between the USB-C charger and MagSafe Charger as it doesn’t help present the data which the article is about: How quickly does the MagSafe Charger charge an iPhone 12 from 0-100% with various USB-C chargers.Collecting charging data was a long process!Firstly I have to drive the battery level of the test iPhone 12 down to the point where it doesn’t boot. This means it could be possible in the future that certain chargers could be ‘blacklisted’ or certain chargers may only work with certain devices. There may be some inaccuracies within the data or unseen issues with the testing setup. The same equipment was used for each test, only the USB-C charger changed between tests. I didn't perform internal measurements and all measurements include power consumed and current drawn by both the MagSafe Charger and iPhone 12 combined. Current and power measurements are measured to the MagSafe Charger and iPhone 12 as a ‘system’. The iPhone had cellular and Bluetooth turned off and no SIM. The graph title gives any specific details of the test run which are relevant. Additional voltage drop will be introduced via the USB-C connector contact resistance which is expected to be of a similar magnitude. Maximum Vdrop across the current measurement resistors at 3Amp (which is the maximum current the MagSafe Charger could negotiate with the USB-C charger) is 3Amp x 0.015 = 0.045V or 45mV. The PD Analyser includes 0.015 Ohm current measurement resistors which I believe have minimal impact on performance of the MagSafe Charger or the voltage measurements. Two test runs (0-100% charged) were performed per USB-C charger. WiFi was switched on during each test run. iPhone 12 was box-fresh and no iCloud login provided, no Siri enabled and no location services or cellular. Battery optimisation was disabled on the iPhone 12. It was then left in this state to cool for at least 2 hours prior to the next test run. Between test runs the battery on the iPhone 12 was fully depleted to the point where the iPhone would not boot. Now connect the USB cable from the MagSafe Charger to the PD Analyser. Connect the PD Analyser to the USB-C charger. Connect the PD Analyser to the MacBook, with analysis software running. This is the point where the iPhone 12 will not boot. Discharge the iPhone 12 battery to zero percent charge. Force-close all running apps on the iPhone 12. ![]() I do struggle with calling it a charger and the charger it connects to also a charger.Analysing the charging test results Initial thoughts on the dataI'm presenting basic comparison data to give a little more insight into what happens to the charging current when a MagSafe Charger is used with an Apple or non-Apple USB-C Power Delivery charger and an iPhone 12. Oh, but first, please accept my apology to the whole internet for using the word ‘puck’ when referring to the MagSafe Charger on the graphs. Let's now take a look at the data which was captured. The iPhone was not unlocked and the screen only stayed illuminated for a few seconds.So, that’s the equipment required along with a basic test method. When checking the battery percent I left the phone on the MagSafe Charger and tapped power button once to see the charge level. If it's under 100%, keep charging.
