Alloy Shell Super Fast Charging Power Bank 20000mAh with LCD Display and Multiple Colours

This portable power bank delivers 20000mAh of capacity, suitable for charging mobile phones and tablets multiple times when you are away from a wall socket. Its construction centres on a polymer lithium ion battery in a soft case, protected by a hard-wearing alloy external shell measuring 140mm in length, 66.5mm in width, and 27.5mm in thickness. The device offers super fast charging at 22.5W alongside PD18W two-way fast charge, with a stated conversion efficiency of 85 percent. Practical additions include an LCD screen for checking battery status and an integrated LED flashlight. It is available in four distinct colours: black, blue, green, and red. A higher capacity 30000mAh version is also offered, which shares the same length and width but increases thickness to 39mm.

Technical Specifications and Build Quality

The power bank's performance and physical form are defined by several key specifications and material choices, all detailed in the product information.

Battery Capacity and Charging Power

This model provides a battery capacity of 20000mAh, intended for extended use. It supports super fast charging output at 22.5W, which can replenish compatible devices quickly. The power bank itself can be recharged via PD (Power Delivery) input at 18W, facilitating two-way fast charging. The product information states a power conversion rate of 85 percent, indicating the efficiency of transferring energy from the internal battery to your connected device.

Physical Dimensions and Shell

The power bank has a compact form factor, with dimensions of 140 millimetres in length, 66.5 millimetres in width, and 27.5 millimetres in thickness for this 20000mAh variant. The external casing is made from an alloy material, creating a rigid shell designed to protect the internal polymer lithium ion battery. For users requiring more capacity, a 30000mAh model is available, which maintains the same 140mm x 66.5mm footprint but has an increased thickness of 39mm.

Display and Additional Functions

An LCD display is fitted to the unit, allowing you to monitor the remaining charge level of the power bank itself. This helps plan your usage and know when to recharge the device. Furthermore, the product includes a built-in LED flashlight, adding a utility function for situations requiring extra illumination, separate from its primary charging purpose.

Colour Options and Model Variants

The power bank is offered in several configurations, allowing selection based on visual preference and technical requirements.

Available Colour Finishes

You can choose from four different colour finishes for the alloy shell: black, blue, green, and red. This selection provides a degree of personalisation, enabling the power bank to match your style or other gadgets.

Capacity and Charging Speed Variants

Beyond the 20000mAh super fast charging model, the product is available in other configurations. These include a 30000mAh model with super fast 22.5W charging, and both 20000mAh and 30000mAh variants that offer standard 2A fast charging instead of the super fast charging. The 30000mAh models are physically larger, with a thickness of 39mm compared to the 27.5mm of the 20000mAh versions.

Identifying Your Required Model

When selecting, consider both the battery capacity (20000mAh or 30000mAh) and the charging technology (super fast 22.5W charge or standard 2A fast charge). Your choice will affect how many times you can charge your devices and the speed at which they recharge. The physical size difference is also a factor, with the higher capacity models being thicker.

Practical Usage and Key Benefits

This power bank is designed for on-the-go power needs, combining capacity with useful features.

Extended Power for Mobile Devices

The 20000mAh capacity is suited for topping up smartphones and tablets multiple times, making it a practical companion for travel, long commutes, or days out. The super fast 22.5W charging capability means compatible phones can regain a significant charge in a short period, reducing downtime.

Convenience of Integrated Features

The inclusion of an LCD display removes guesswork about how much charge remains, aiding in power management. The LED flashlight serves as a handy secondary tool, potentially useful in emergencies, while camping, or finding items in a bag. The alloy shell contributes to a robust feel and may offer better protection against minor impacts compared to plastic casings.

Versatility Through Model Choice

The range of models means you can select based on your priority: maximum capacity with the 30000mAh versions, or a more compact profile with the 20000mAh versions. Similarly, you can choose between the top-tier super fast charging or the standard 2A fast charging to match your devices and budget.
