Have you ever experienced a time when you were charging your phone it just took forever!? Or maybe you've even had your phone die on the charger? The Practical Meter is here to help you solve these problems by showing you in real time how fast your device is charging. Using the Practical Meter you can avoid common USB charging problems, and it's compatible with any USB device.
We have taken the guessing game out of off-grid solar charging! The Practical Meter's real-time power display lets you angle your solar panel toward the sun to charge your mobile devices at full speed!
USB stands for Universal Serial Bus, but nowadays USB is not so universal. There are versions 1.0, 2.0, and 3.0 of USB, all of which have differing power requirements. On top of this some manufactures add their own proprietary blend into the mix, making it so their devices work best only with their own brand of chargers. Accidently using a bad combination of power sources and devices won't hurt your device, but can lead to charge times up to 4 times longer.
The choice of charging cable can have a huge effect on phone charging speeds. With all the different USB standards that exist today it's easy to accidently use an out of date cable, resulting in longer charge times. Some USB cables are dedicated for charging, and often times these charge only cables charge faster than sync/data cables.
