The Swiss Army Knife of phone tools, PK’s K’isauve is a battery, SSD, cable in one

Here’s a handy pocket-sized gadget for your smartphone with a distinctly French flavor. Developed by PK Paris, the K’isauve (which means “well-liked”) is a three-in-one device that manages to combine an SSD, a backup battery, and the necessary sync or charging cable into a diminutive body.

The latest version, the K’isauve SSD 3.1C is the world’s first USB key that’s equipped with an SSD and USB 3.1 technology. That means it’s compatible with the latest MacBook. There’s 128GB of storage space, and you can transfer a standard HD film in just 3 seconds. It can hit read and write speeds of 530 MB/s and 520 MB/s respectively. While slightly larger than its predecessor, it’s still very compact at 52 x 52 x 15.9 mm.

The battery is good for around an extra 90 minutes of power for your iOS or Android device. PK says the USB 3.1 cable allows it to recharge an iPhone 6 in under two hours. It also sports a rubber belt that makes it waterproof, and enables it to withstand falls of up to 50 meters unscathed.

It’s compatible with the iPhone 5 and up, a long list of Android devices, and any new laptops with USB 3.1 support.

If you want to pre-order one for delivery this summer, keep an eye on the PK Paris website. You can get a 30 percent discount if you pre-order, taking the price down to $160 instead of $230.

The previous USB 3.0 version supports speeds up to 100 MB/s and measures just 43 x 43 x 11 mm, but also offers 90 minutes battery life and 128GB of storage. It costs about $170 for the Android version and $180 for the iOS version. The original 16GB version with 30 minutes of battery costs around $75 for Android or $85 for iOS.
