Nomad today announced the launch of an updated version of its ChargeKey portable charger, with the new model gaining support for 240W charging and 10Gb/s data transfer speeds.

The USB-C to USB-C ChargeKey can fast charge an iPhone, iPad, MacBook Pro, Android device, and more at up to 240W. The prior version of the ChargeKey was limited to 60W charging speeds and USB 2.0 data transfer speeds, so the new model offers notable improvements for MacBook users and those who need a portable cable for data transfers.

Like the previous ChargeKey, the 240W model has a braided nylon cable with electroplated zinc cable housings. It's compact and small enough to fit on a keychain, and the two cable tips attach to one another magnetically when not in use.

Nomad is selling the ChargeKey for $25, and it is available from the Nomad website starting today.

RIP, MacBook Ultra

Apple today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name. The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...

Why would someone buy this vs a longer cable?

This wouldn't hurt the battery to charge a device like the iPhone at 240w as opposed to what it would normally charge at on its own like 35w?

The phone negotiates the power it needs to charge. It won't accept the larger amount and just takes in what it needs. This will give you more information at a rather technical level:

I think people are trying to do the lightning rod method these days: stand out in a thunderstorm holding a long copper rod routed to a USB-C connection. If you survive the strike, apparently the phone is fully charged in 0.23 seconds. This is called the new literal Lightning connector. ;)

The most unique feature of this charging cable is probably support for 10Gb/s data transfer speeds. It's pretty rare to see a high wattage charging cable that also supports high speed data transfer.

I'm not sure I would want to jam a high-quality cable with connectors with my keys in my pocket. But it's a cute idea.

Just what I was thinking! My pockets get pretty cruddy depending if I’m working in the garden or under the truck. How does this thing prevent for lint and finer particles from packing the inside of the USB connectors?

What would be a use case for this??

You have a phone, and you have a battery pack. Neither is Magsafe compatible. You're sitting in the airport or in a meeting, wall port not available. If you only had a cable somewhere that would connect the two, without the unsightliness of a curled up lightning cable getting caught on your arm rest every time you move around. As luck would have it, you've got this handy dandy cable you always keep attached to a hook in your backpack.
