Features and Construction

The core of this power bank is its substantial 20000mAh polymer lithium-ion battery, designed to provide multiple full charges for a typical smartphone. The unit’s construction includes an integrated solar panel on one face, which can provide auxiliary charging when exposed to direct sunlight, supplementing the primary USB charging method.

Material and Build

The device utilises a polymer lithium-ion battery cell, a common technology in modern portable power banks known for its stable energy density. The factory three proofs certification indicates it has passed basic factory tests for resistance to moisture, dust, and shock, though specific IP ratings or drop-test results are not detailed in the source material. The exterior finish is offered in orange, yellow, black, or green.

Size and Practical Fit

With dimensions of 161mm in length, 79mm in width, and 17mm in depth, this solar power bank is designed for portability. It can easily fit into a backpack, glove compartment, or travel bag. The provided measurements give a clear indication of its physical footprint, which is important for users comparing storage space against battery capacity.

Uses and Placement

Designed for general-purpose charging, this power bank is a versatile tool for a range of scenarios where access to a wall socket is limited or unavailable. Its solar capability adds functionality for extended outdoor use.

Event or Professional Use

For professionals working on-site or at outdoor events, this unit can serve as a reliable backup to keep communication and photography equipment operational. Event organisers, surveyors, or security personnel may find it useful for maintaining device charge throughout a long shift where power outlets are scarce.

Everyday Home Use

At home, it acts as a convenient portable charger for use in different rooms or during power outages. Families can use it to keep multiple family members' devices charged from a single central unit, reducing clutter from individual chargers, especially useful during trips or days out.

Benefits and Buying Value

The value of this solar power bank lies in its combination of high capacity, multiple charging ports, and solar-assisted charging, all housed in a compact, colour-choice body with a stated durability certification.

Reuse and Low Maintenance

As a rechargeable device, it is designed for repeated use over time. The polymer lithium-ion battery is a standard type that benefits from regular full charging cycles. Basic care involves keeping the solar panel clean and storing the unit in a cool, dry place when not in use for extended periods to help maintain battery health.

Why Choose This Product

This power bank is a suitable choice for users seeking a high-capacity 20000mAh battery with the added flexibility of solar charging. The factory three proofs certification offers a baseline assurance of build quality, while the multiple USB outputs provide practical utility for charging more than one device at a time.
