Binary Star Power Bank Adapter / Trozk
The Trozk Binary Star collapses three travel objects into one: a 6,800mAh power bank, a 35W GaN wall charger and a phone stand. Its two halves clip together and pull apart, so the charger can stay in the wall while the bank goes in a pocket, which is where the name comes from. A semi-transparent frosted shell exposes the internal circuitry, and a coloured loop at the top works as both an accent and a clip point. Gallium-nitride electronics let the wall side run cooler and smaller than a conventional silicon charger. It suits the light traveller who would otherwise pack a separate plug, battery and stand, and who values a compact, visibly engineered object over raw capacity: at 6,800mAh this covers roughly one to one-and-a-half phone charges, not a weekend away from a socket.
Design intent
- +Splitting the device into a detachable power bank and wall adapter is the central idea: the same object charges from the mains, stores that charge, and props the phone while doing it, so three separate travel items become one that clips together.
- +The third-generation gallium-nitride adapter is what makes the consolidation physically possible, switching at higher efficiency and lower heat than silicon so a 35W charger can shrink to a size that pairs with the bank without bulk.

Trade-offs
- -Folding a wall plug, a stand and a battery into one compact body caps the cell at 6,800mAh, modest for a power bank, so it favours a top-up role over multi-day capacity, and a dedicated bank will hold far more.
- -Because the bank and adapter are separate clip-together modules, each is a part that can be misplaced on its own, and the join between them is a mechanical interface a single sealed charger never has to maintain over time.
