Different USB standards

The Practical Meter helps you distinguish if you are charging fast or slow on using the wall outlet, car charge, laptop, battery pack, or any other USB source.

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 cables won't hurt your device, but can lead to charge times up to 4 times longer.

CABLES MATTER

The choice of charging cable can have a huge effect on phone charging speeds.  There are two types of USB cables, charge only and sync/data.  With all the different USB standards, USB charging ports can perform differently with each type of cable.  Often times, a charge only cable with charge faster than the sync/data cable (every smartphone ships with a sync/data cable).  Having a Practical Meter allows anyone to test the USB cable/port combination to ensure max charging speeds.  

The example shows one phone charging with a sync/data cable (white cable) and the other with a dedicated charging cable (black cable). Do you see the difference?

FAQs

  • Can I still transfer data through the Practical Meter?

    Yes. The Practical Meter by itself allows the transfer of data between client and host.  This allows you to monitor charge rates while transferring music/photos on a phone, or see how much power a USB flash drive uses.

  • Does the Practical Meter work with Tablets?

    Yes.  The Practical Meter can measure up to 10 Watts (2 Amps) so you can see if your tablet is charging at full speed.

  • Will the Practical Meter work with my iPhone 5?

    Yes.  We do not currently sell and iPhone 5 cable, but the Practical Meter will work with the iPhone 5 or any other USB device.  Just use the cable that came with your device at the time of purchase.

  • Do the 3-in-1 cables transfer data?

    No these cables are optimized for charging only, so the data/sync functionality was necessarily removed.

  • How much power does it use?

    The Practical Meter only consumes a fraction of a watt, so it will not effect charging times on your phone. 

  • Can I charge multiple devices at a time with the 3-in-1 cables?

    Yes, if your USB power supply can supply enough power for all the device simultaneously.  You'll have to look at your device and supply power requirements, or use the Practical Meter to see if both devices are charging at full speed.
