The unit comes in multiple configurations including standard capacity models and 2000 mAh variants in both colour options.

Features and Construction

This power bank combines high-capacity charging with practical monitoring features in a portable format suitable for travel or everyday use. The plastic shell provides protection for the internal battery components while maintaining a manageable size and weight.

Material and Build

The power bank utilises a polymer lithium-ion soft bag battery type, which differs from traditional cylindrical battery cells by offering more flexible packaging within the plastic housing. This battery technology is contained within a plastic outer shell that forms the main body of the unit, providing structural integrity and surface protection. The plastic material allows for the creation of the rectangular 156mm x 82mm x 41mm form factor while keeping overall weight manageable for portable use.

Size and Practical Fit

Measuring 156mm in length, 82mm in width, and 41mm in depth, this power bank maintains a compact rectangular profile despite its 40000 mAh capacity. These dimensions allow it to fit comfortably in backpacks, laptop bags, or travel luggage without occupying excessive space. The unit's proportions balance capacity with portability, making it suitable for carrying during commutes, business trips, or outdoor activities where access to mains power may be limited.

Uses and Placement

With its general type designation and substantial capacity, this power bank serves multiple charging scenarios for various electronic devices. The LCD display adds functionality by providing users with immediate information about available power before and during use.

Event or Professional Use

For professional settings requiring extended device operation, the 40000 mAh capacity supports multiple charges for smartphones, tablets, or portable accessories. Event photographers, field researchers, or business travellers can utilise the power bank to maintain device functionality throughout extended work periods away from power outlets. The LCD display allows for precise monitoring of remaining capacity, helping users plan their charging needs during conferences, site visits, or multi-day events where power access may be inconsistent.

Everyday Home Use

In domestic environments, this power bank serves as a convenient charging station for family members' devices during power outages or in rooms with limited socket access. The black or Chinese red colour options allow for aesthetic coordination with home decor or personal preferences. Household members can use the unit to charge smartphones, tablets, Bluetooth speakers, or other portable electronics while moving between rooms or during evening hours when devices are typically away from wall chargers.

Benefits and Buying Value

The combination of high capacity, monitoring capability, and compact design delivers practical advantages for users requiring reliable portable power. The product's specifications provide clear parameters for evaluating its suitability for individual charging needs.

Reuse and Low Maintenance

The polymer lithium-ion battery technology supports repeated charging cycles with the 85% conversion rate indicating efficient energy transfer during each use. The plastic housing requires minimal maintenance beyond basic cleaning with a dry cloth to maintain appearance. With proper storage in moderate temperatures when not in use, the power bank provides ongoing charging capability without complex care requirements or specialised handling procedures.
