Toast is a product design solution intended for backpackers, it is estimated up to 5000 people go missing on trails around the world each year and with most using smartphones as their main source of navigation this presents a level of risk to them should it run out of charge.
This proposal aims at reducing this figure by encouraging users to monitor the amount of charge they use while also reducing the human led factors that could result in a flat battery. The power bank is made up of 3 components; the main body and the 2 modules that fit either side. These modules can be removed and thanks to magsafe technology snap to the back of an iPhone and provide charge wirelessly.
The main body has several features to combat the risk of running out of power. It has a built-in buffer preventing it from running completely flat, leaving the user with 10% emergency power that they can utilise at any time. It also offers an output function that can be set by the user to only distribute a certain amount of charge. These features working together reduce the risk of accidentally leaving a device charging in a rucksack for too long and discovering a flat battery which in a situation where you need to make an emergency call could put the user at further risk.
