Free yourself from the USB umbilical cord

Free yourself from the USB umbilical cord.

There is a new universal standard for wireless charging – Qi.

This will make the wireless charging market explode. And I think that it’s about time.

Even though the technology has been around for ages, (anyone own a Sonicare?), they haven’t found a way to make it easy to charge our devices. Phones, tablets, toys all have to be plugged in. It’s time to free yourself from the USB umbilical cord.

How it works

Qi (the Chinese word for “energy flow“, pronounced like the “chee“ in “cheese“) is the universal standard for wireless charging of battery operated devices like cell phones, iPods, MP3 players and cameras.

The wireless power transfer occurs through electromagnetic induction. With inductive charging the required power reaches the device not through a traditional cable but rather wirelessly through the use of electromagnetic fields. The principle is very simple: the Qi Sender (Charging Station) transfers the required energy to the Qi receiver (the mobile phone).


Just a sample of what you can charge

  • Smart Phones that are Qi enabled, Tablets,
