Once you’ve got a charger, stand, some extra storage and a few other bits, you’ll need a bag for all your mobile accessories. WonderCube aims to replace them all with a handy cube that fits on your keyring.
It has a built-in Lightning and microUSB cable, a micro-suction phone stand, USB key and microSD card reader, a USB connection, emergency 9V battery connection and mini torch. And all in a package no bigger than one cubic inch.
In other words,
A 9V battery should give you three and a half hours extra talk time for Android and iOS devices.
Want to make it extra personal? You can have a name or message engraved on it too.
It’s by no means a one-stop shop for all your mobile needs, but it is a very neat little device that packs a lot into a small package. And for $69 (£46), or $49 if you buy from Indiegogo, it’s very affordable too.
It’s passed its funding goal and should ship in August.
