Features and Construction

This power bank is constructed with robust materials and includes practical features for efficient charging. The polymer lithium ion battery provides stable power delivery, while the square aluminium shell adds structural integrity. The outer plastic shell keeps the unit lightweight and portable. Multiple USB output ports ensure you can charge compatible devices simultaneously without slowing down overall charging speed. The wireless charging pad simplifies charging – simply place your smartphone on top and it begins charging at 15W.
Material and Build
The power bank uses a polymer lithium ion battery, a type known for its reliability in portable electronics. The battery is housed inside a square aluminium shell, which helps with heat dissipation and adds a sturdy feel. The outer casing is made from plastic, keeping the overall weight manageable at less than 400g (based on typical 20000mAh models). This combination of materials makes the unit suitable for carrying in a bag or pocket during daily commutes or longer trips.
Size and Practical Fit
Measuring 149 x 79 x 18mm, this power bank is compact enough to slide into a small bag or even a large jacket pocket. Its slim profile means it does not add significant bulk to your carry. The flat, rectangular shape makes it easy to stack alongside other items such as a phone, wallet, or keys. The colour options – retro green, business black, and simple white – allow you to pick a finish that matches your accessories or style.
Uses and Placement

This power bank is designed for on-the-go charging in a variety of settings, from travel to daily use. Its high capacity and fast charging capabilities make it a practical choice for professionals, students, and anyone who relies heavily on their smartphone or tablet throughout the day. The wireless charging feature adds convenience, letting you charge without plugging in a cable.
Event or Professional Use
For business travellers, the 20000mAh capacity ensures your phone, headphones, and other USB-C or wireless devices stay charged during long meetings, flights, or conferences. The 22.5W super fast wired charging means you can quickly top up a phone before a presentation. The multi-USB output is useful for sharing power with colleagues or charging both a phone and a tablet simultaneously from one unit.
Everyday Home Use
At home, this power bank can serve as a backup charger during power cuts or when wall sockets are limited. Its wireless charging pad is handy for charging phones overnight on a bedside table without needing a cable. The compact size means it can be stored in a drawer or on a shelf without taking up much space, ready for days when you need extra power away from home.
Benefits and Buying Value

Choosing this power bank offers practical benefits over lower-capacity or slower chargers. The 20000mAh capacity reduces the frequency of recharging the power bank itself, and the 22.5W wired plus 15W wireless output speeds up the charging process for compatible devices. The multi-port output removes the need for several separate chargers when travelling. The combination of polymer lithium battery and aluminium shell supports long-term use.
Reuse and Low Maintenance
The power bank can be recharged hundreds of times, maintaining its capacity over years of use. No special maintenance is required – simply charge it using a standard USB-C or Micro USB cable (depending on model) and a wall adapter. The wireless charging feature reduces wear on charging ports on your phone, potentially prolonging its lifespan. When not in use, the power bank holds its charge well, so you can keep it in a bag and rely on it when needed.

This power bank stands out for its combination of high capacity (20000mAh), fast wired and wireless charging, and multi-port output – all in a compact, coloured plastic-and-aluminium design. It avoids the hassle of carrying multiple chargers and supports both fast and standard charging modes depending on your device. The colour options let you personalise your tech accessory. For anyone looking for a versatile, everyday portable charger that handles multiple devices and charging methods, this product offers a straightforward solution.
