5 things you didn’t know about wireless charging

Twenty years ago the mere thought of wireless telephones was enough to make us raise our eyebrows; now, we can even ditch the cables we use to charge them. And because the highest failure rate in mobile equipment tends to be the fraying and kinked power cord, this is very good news.

While it’s not yet mainstream tech, phones like the Nokia Lumia 920 and the Nokia Lumia 820 are the trailblazers – smartphones that use wireless charging. Let’s take a closer look…

1. Wireless charging works by using induction – the same basic principle that Michael Faraday discovered way back in 1831. An electrical current in one part of the charger creates a magnetic field, which in turn creates a voltage – and that voltage powers your phone, wire-free! You simply place your phone on top of the charging unit, just like, with an induction cooker, you place your pan on the hob. Simple!

2. Like any other emergent tech, there are competing systems. Nokia has adopted the Qi standard, developed by the Wireless Power Consortium, a cooperation of worldwide companies that aims to create a proprietary standard for wireless charging technology that will eventually operate worldwide. ‘Qi’ comes from the Chinese concept of energy flow in traditional medicine – pretty appropriate, we think!

3. You won’t always have to bring your charging pad with you. Nokia, for instance, has teamed up with Virgin Atlantic and Coffee Bean And Tea Leaf, which means that when you’re the London Heathrow Clubhouse lounge, or in a Coffee Bean café, you’ll be able to make use of their table-top charging stations while you relax. Now that’s twenty-first century customer service if ever we saw it.

4. The kit is amazing. There’s the Nokia Wireless Charging Plate, the Nokia Wireless Charging Pillow by Fatboy – for when your hard-working phone fancies a well-deserved lie-down – and the Nokia Wireless Charging Stand, which allows you to charge up whilst on video calls. We’re also very fond of the JBL PowerUp Wireless Charging Speaker for Nokia, which will charge your phone as you’re listening to your favourite tunes. Just connect your phone to the speaker with a single tap, then lie the phone down. Couldn’t be funkier if it tried.

5. Finally, there’s the wider environmental implications of wireless charging. Leaving a phone charger plugged in, after you’ve powered your mobile up, might not make a noticeable difference to your home’s total energy consumption, but when tens of millions of people do the same thing the amount of energy wasted can be huge. Wireless charging only works when your phone touches the charger. No touching. No power. It’s a greener way of energizing your phone and that got to be good news, – now where’s that Charging Pillow?
