Most vehicles have a flurry of USB sockets or 12V cigarette lighters dotted around the cabin that allow you to charge a mobile device. In some cases, however, these ports might be occupied by another device or in some cases, be entirely absent at the rear of the cabin.
Power banks are, in most cases, portable battery packs that can be taken with you on-the-go; you can place one within the centre console, glove or door departments or even in a bag all while providing some extra juice to your phone. These portable battery packs will not only deliver power to a smartphone but also to any device that accepts a USB input: Bluetooth speakers, cameras, laptops and even portable games consoles like the Nintendo Switch.
There are countless options on the market to choose from, but which one should you choose? At TotallyEV, we’ve condensed a comprehensive list of our favourites, so that you can make an informed purchasing decision without having to spend hours on research.
