In an era where our smartphones, tablets, and laptops are essential for work and play, a reliable power bank has become a must-have accessory. Whether you're commuting, traveling, or simply spending a day out, running out of battery can be a major inconvenience. To help you stay charged, we've tested and reviewed the best power banks available in the UK for 2025.
What to Look for in a Power Bank
Before diving into our top picks, it's important to understand the key features that make a power bank stand out. Capacity, measured in milliampere-hours (mAh), determines how many times you can charge your device. For most users, a 10,000mAh power bank offers a good balance between portability and power, providing around two full charges for a typical smartphone. If you need to charge multiple devices or a laptop, consider a 20,000mAh or higher model. Additionally, look for fast charging support (such as Power Delivery or Quick Charge), multiple ports, and pass-through charging capability.
