The cube that can do it all
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, it can charge your phone, sync files and prop your phone up in either landscape or portrait by sticking to the back. Though in order to charge your phone on its own, you'll need to slot in a 9V battery. These can be bought from any supermarket, but it's a shame it doesn't have its own power source. Still, maybe that's asking a bit much considering how small it is.
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.
