The Vonmählen High Six is an ultra-portable charging cable accessory that has made 350% of its Kickstarter campaign already

The German start-up Vonmählen touts the subject of its latest crowdfunding campaign as a 6-in-1 accessory that a tech fan can keep on their keychain to avoid the consternation of having forgotten to throw one's favorite or most crucial cable in their bag while on the go.

It is a successor to the High Five, and is built along the same lines of being an ultra-short, and, thus, ultra-portable, cable with USB type-C connections at either end, but with adapters for USB type-A, Lightning or indeed microUSB if necessary.

However, the High Six has been designed to improve on this idea with a new, metallic casing to store and protect the cable in question. The main part of the accessory, however, still has magnetic contacts so as to keep it looped around a keyring by itself if necessary. Then again, the case may offer a higher-end appearance, and also confers a handy bottle-opening function on the new High Six.

This concept has, admittedly, been seen before: for example, the also-crowdfunded inCharge from Rolling Square is built along the same lines. However, Vonmählen asserts that the High Six is now the "most compact" keychain cable on the market, at a total of 63 centimeters (cm, or 24.8 inches (in)), as opposed to 70cm (27.6in) in the High 5.

It can also deliver up to 3 amps (A) of charge along its 5 internal wires, encased in protective TPE, although that is for its USB type-C to C or A modes (to charge a device in extremity at up to 60 watts (W)), and drops to 2.4A via microUSB or Lightning.

The Vonmählen High Six starts at €21 (~US$24) on Kickstarter, where it has attracted just over €52,000 (~$60,000) in terms of backing, as opposed to its original €15,000 (~$17,000) goal, at the time of writing.

Alternatively, the inCharge 6 is now available on Amazon.com
