Here's a APPY solution that should brighten up a wet weekend away camping - a wood powered stove that also recharges your smartphone.
The CampStove can burn sticks, pine cones and biomass to generate enough heat and power to charge a phone, light, satnav or gadget that is USB chargeable.
The quirky invention converts the heat from the fire to power a fan and produce the electric charge that US manufacturers BioLite claim eliminates the need for expensive fuel when users are without electricity.
They say its CHAR-GE GRILLED capabilities still provide enough power for a fully fired stove to cook a meal's essentials when a device is on charge.
Users in the US hailed its effectiveness during Hurricane Sandy when over six million people lost electricity with some able to carry on cooking and keeping electronics charged using the device.
The stove's powerpack slips inside the small 21cm by 12cm cooking chamber and is lit with a match or lighter, weighing in at 935g.
It currently retails at £80 ($129) in the US and is set to be available in stores in the UK next summer.
