RAZER KISHI

Pawing away at a glass screen is fine for games designed for touchscreen interaction; but when tackling console-orientated fare, you want a D-pad, sticks, triggers and buttons. In short, you want a Razer Kishi. Its innovative stretchy design means it fits most modern smartphones, in seconds transforming your blower into something resembling a PS Vita. It doesn’t even need charging, as power is drawn from your device. Most importantly, the controls are great. from £80 / razer.com

If your phone’s battery runs low while gaming, pass-through charging means you can plug your usual cable directly into the Kishi to juice up.
