While having a gamut of charging options is great when you have mobile gadgets like smartphones and tables, what isn’t so great is having those options take up an inordinate amount of time charging your gadgets. What’s the use of a charger, if it takes such a long time to reach a full battery state or, even worse, has your battery continue to drain as you use your device because of the low rate of charging current? Power Practical aims to dispel the uncertainty of whether you’re mobile gadget is getting enough charge from your charging option, whether it be a USB port, a solar mobile charger, or a portable charger. Its product, the Practical Meter, is currently a prototype, but what it does is measure the exact amount of current passing through a USB port to a mobile device in order to determine if there’s a problem that needs to be fixed.
Power Practical conceived the idea for the Practical Meter in order to remedy a problem that occurs often when charging via USB: varying power output. People are generally unaware that the USB bus interface often encounters inconsistencies when the current needed for charging devices goes beyond 2.5 watts. The result of this situation is, naturally, time wasted on waiting for mobile gadgets to get fully juiced, when there are ways to ensure that charging times achieve optimal speeds. Weighing in at just 0.3 ounces and measuring 1.7 inches long and 0.9 inches wide, the Practical Meter is meant to serve as an ultraportable way to get an accurate reading about the power output of any USB port.
The Practical Meter works much like a USB throughput port. Plugging it into a USB port doesn’t mean the loss of one more port for your connectivity options. The meter has a USB port included in its design that allows you to carry on charging your mobile devices as if you were connected straight into the host port.
The Power Practical Meter is currently being funded through Kickstarter to get its chances of production up.
