Plain-English guides to watts, standards, ports and compatibility, so the box tells you the truth.
A plain-English UK guide to choosing a USB-C wall charger for your phone, tablet or laptop: how much wattage you need, how multi-port chargers share power, which cables to use, and how to buy safely.
Learn how a power bank's mAh rating relates to watt-hours, why real phone charges fall short of the label, how to match capacity and output to your devices, and where to check airline rules for lithium batteries before you fly.
How charging power, battery capacity, wireless standards, smart-home platforms and ports work, what the numbers on a box mean, and which details decide whether a gadget will work with what you already own.
Guides explain general rules. Manufacturers set their own specifications and support policies, so check the current details for the exact model before you buy.
