Features and Construction

The power bank's design focuses on combining capacity with user information through its key features. The construction balances internal battery protection with external practicality for daily carrying and use.

Material and Build

The internal square aluminium shell houses the polymer lithium-ion battery cells, providing structural support and assisting with thermal management during charging and discharging cycles. This metallic core is surrounded by a plastic external housing that reduces overall weight and provides impact resistance. The combination of materials results in a product that feels substantial yet remains portable enough for regular travel use.
