Iphone Charging: Watt Really Matters?
by Will Rooney
The purpose of this experiment was to see what type of phone charger most effectively charges an iPhone. People rely on their phones everyday for work, school and social contact. It is important that phones charge quickly so daily tasks are not interrupted. In this project the materials used were an authentic Apple charger, a Amazon-bought charger, a wireless charging pad, a four and ten watt adapter, and an iPhone 8+. Each trial measured the time it took for the phone to get to 100% from 0%.
The hypothesis stated that the authentic Apple charger with the 12 Watt Adapter would have the fastest charging speed due to its low wattage consumption and the extra 12 watts added to it from the adapter. It was predicted the wireless charger with no adapter would have the slowest charging speed because of its high watt consumption, having no extra wattage from an adapter, its fast-charging style, and having to use magnetic fields to take in power (Laukkonen, 2020). The hypothesis was supported. The authentic Apple charger had the fastest charging speed with a time of 2:46:32 hours. The wireless charging pad had the slowest charging speed of 5:04:34 hours. The Amazon-bought charger had a very close charging time to the authentic Apple charger with only a 10 minute difference with the same adapters. |
