The Practical Meter: Know your power! By David Toledo - Kickstarter


The Practical Meter is a USB adapter that displays the power being charged with the five bars on the surface.


The size of the main body is 1.75 inches (about 4.45 centimeters) × 0.75 inches (about 1.9 centimeters), meaning that one bar is charging at 1 watt. The charging time is shown in the graph below, for example, it takes about 1.5 hours to complete when charging iPhone with 5 watts, it takes about 8 hours to charge with 1 watt.


When examining the charge power of the iPhone being charged from the USB port of the desktop PC using The Practical Meter, only 2.5 watts, which is about half of the maximum power 5 watts, came out.


The Android smartphone which is charging from the USB port of the notebook PC also measures the charging power like the iPhone, and it only costs 2.5 watts and it will take about 4 hours to charge.


Charging the iPhone from the Macbook charges with the highest electric power of 5 watts, and takes only about 1.5 hours to charge. Actually, if the charging cable and port specifications are different, it seems that phenomena such as being unable to charge with the highest electric power will occur.


Therefore, it is Charging Tips that enables charging at maximum power 5 watts at any time, and it corresponds to mini USB · micro USB · Dock connector.


Even if you charge the iPhone from the same PC, if you add Charging Tips, charging will be completed in about 1.5 hours and charging will be completed 2.5 hours earlier than when charging without anything.


Charging tips said that special circuits are embedded in order to always be able to charge with maximum power.


While The Practical Meter and Charging Tips are seeking investment with Kickstarter, at the time of article writing they have collected $ 56,600 (about 5.6 million yen) over the target amount of 9,999 dollars (about 1 million yen) , Commercialization is almost certain. If you invest 7 dollars (about 700 yen) you can get one Charging Tips, you can get one Practical Meter and Charging Tips by 19 dollars (about 1900 yen), shipping to Japan will be charged separately 5 It costs a dollar (about 500 yen). The deadline is 1:21 AM on July 26th in Japan time.
