Could This be the Answer to your Battery Life Problems?

If you are an avid smartphone user and the standard battery just doesn’t last long enough for you, you may look to buy one of two options; the external power bank which can be cumbersome and an inconvenience to lug around, or the battery case which ensures that the sleek design of your phone is completely lost! Bunk is a neat device which aims to eliminate this decision once and for all!

Bunk is a battery pack that magnetically secures to the rear of the phone and charges it using the phone’s inbuilt wireless charging capabilities. This method of charging allows the battery-pack to be removed when it isn’t needed, and its compact size combined with the absence of annoying charging cables makes it convenient to carry around.

The internals are housed within a waterproof casing that is available in eight vibrant and exciting colorways. This is definitely a battery pack that we could get used to using!

For the 79% of smartphone users who use a case [1], the magnetic bunk sticker is simply stuck onto the inside of their case. For the minority who do not use a case, it can alternatively be stuck directly onto their phone.

High strength neodymium magnets locate and secure bunk in place.

Multi-Coil solution intelligently selects the optimal output coil, allowing bunk to align with the receiver coil on any modern smartphone.

Bunk is recharged via a QI receiver in its front casing, and supports ‘pass through charging’ to the user’s phone, allowing both devices to be charged together with a single QI pad. An intelligent charging IC will prioritise charging the phone prior to charging bunk.

Multi-Coil solution intelligently selects the optimal output coil, allowing bunk to align with the receiver coil on any modern smartphone.

Three textures and eight colorways to compliment a wide range of case colors and styles.
