Buying guides
Plain-English guides from the Voxel test bench.
A phone sensor is around 10mm across. A 1in camera sensor gathers far more light. Here is when that difference actually matters.
A phone needs 20W to 30W, a laptop 45W to 100W. Match the charger, the cable and the port before you spend £35 or more.
A plug costs £15, a bulb £19 and a camera £39. Build a useful smart home for £99 without buying a hub you do not need.
Microphones sample the noise, then the headphones play the inverted wave. Here is why 20dB to 40dB figures rarely tell the whole story.
OLED wins in a dark room, Mini LED in a bright one. Compare 800 nits against 1,500 nits before you choose a 55in or 65in set.
Fourteen inches suits most people. Here is how 13in, 14in and 16in laptops differ in weight, screen space and battery life.
