Features and Construction

The power bank is built around its core components: a high-capacity polymer lithium ion battery housed within a square aluminium shell, all encased in a plastic exterior.

Material and Build

The internal structure uses a square aluminium shell, which houses the polymer lithium ion battery cell. This metallic shell contributes to the product's rigidity and aids in managing the battery's operation. The outer case is made from plastic, forming the protective and tactile exterior of the power bank. This combination of materials results in a sturdy and functional build suitable for regular portable use.

With overall dimensions of 135 millimetres in length, 68 millimetres in width, and a slim 15 millimetres in depth, this power bank maintains a compact profile. Its size is optimised to hold the 20000mAh battery while remaining easy to slip into a backpack, laptop bag, or even a larger handbag, ensuring it's a convenient travel companion rather than a cumbersome item.

Uses and Placement

Event or Professional Use

For professionals on the move, at trade shows, or during long days of meetings and travel, this power bank can provide multiple full charges for a smartphone, ensuring communication and navigation tools remain active. The clear digital display allows users to manage their power reserve efficiently, planning when to recharge the bank itself based on visible battery levels.

Everyday Home Use

In everyday situations, it serves as a reliable backup at home during power outages or in rooms with limited power sockets, allowing you to charge devices away from a wall plug. Its simple 5V/2A output is broadly compatible with most phones and smaller tablets, making it a versatile household accessory for all family members.
