Practical Meter is an accessory for smartphones, its role is to help us discover where exactly we can charge them very quickly. As you can see from the image, we are talking about a very small device that we insert between the charging source and the charging cable of our terminal, it has an LED display that tells us what power that source provides. According to the calculations made by its developer, the lighting of a single bar means that a iPhone it will charge in 8 hours at that energy source, and the lighting of all 5 bars indicates that the iPhone will charge in 1.5 hours.
Using Practical Meter you can check any energy source and to be honest, it is very good to be able to find out which of the charging methods is the most efficient, especially since Apple has implemented an extremely fast charging system in its iPhones. So far Practical Meter has barely received the funding it needs to reach the market, so in the following months the first devices should reach backers, and the product itself could be available for purchase next year.
