MagSafe makes a full comeback for your USB-C MacBooks
One feature that seasoned MacBook users may miss is the good ol' MagSafe connector, because no one wants to accidentally drag a pricey laptop off the table. Alas, ever since Apple made the jump to USB-C, it decided to retire its handy magnetic invention -- it even stopped short at releasing a MagSafe-to-USB-C adapter. There have since been a few third-party alternatives, with the earlier ones handling just power delivery (like Griffin's BreakSafe cable), followed by the more advanced data transmitting types with mixed reviews -- they tend to be bulky, nor did they support Thunderbolt 3's full bandwidth, apparently. This is where ThunderMag comes in. Developed by Innerexile over the past three years, this little gadget is claimed to be the world's first truly Thunderbolt 3-compatible magnetic adapter. In other words, ThunderMag can pass through data at up to 40 Gbps (or video at up to 5K) while also delivering 100W of power, thanks to its 24 pins and delicate magnetic shaping -- the latter to protect the cable's high-frequency signal. And of course, the ThunderMag isn't exclusive to MacBooks; just plug it into any Thunderbolt 3 or USB-C port on a device and you're good to go.
USB Power Delivery spec upped to 100W, aims to make proprietary power connectors obsolete
The battle between Thunderbolt and USB 3.0 has only recently begun in earnest, what with mobo's finally emerging to give non-Mac computers access to the 10Gbps interface. While USB 3.0 can't match Thunderbolt in terms of data throughput, it now has the upper hand in power capabilities, as last week the 100W Power Delivery spec was approved for both USB 2.0 and 3.0. That's ten times what Thunderbolt can do, and it means that you can charge up your laptop or power most any peripheral via Universal Serial Bus. Naturally, the new specification relies on beefier cables to deliver maximum juice, but we won't have to go replacing all our old wires -- it includes a means to check attached cables and devices and set the voltage and amperage accordingly. Perfect, that means we won't have to carry around bundle of proprietary power cords when we travel, and we get peace of mind that charging via USB won't have any, ahem, unpleasant side effects.
