Wires. You either love them. Or you hate them. Ok, maybe you\u2019re just indifferent. But wires can look unsightly. They can cause a trip hazard and they often go walkabouts, leaving you hunting for your charger cable just moments before your battery dies mid-call.<\/p>\n

However, wireless chargers<\/a> put an end to all of this.<\/p>\n

Wireless chargers are neat and they\u2019re always in the same place. What\u2019s more, their design can be remarkably discreet and some even incorporate lights for a sleek and stylish appearance.<\/p>\n

With technology evolving all the time, the speed and capability of wireless charging units are constantly improving. These days, wireless chargers can be found built into sofas, bedside tables, kitchen counters and even desks. They even charge while still in a phone case.<\/p>\n

How to get a wireless charger<\/h2>\n

If you don\u2019t already have a wireless charger built in, they can be quite simply and easily retro fitted without spending out on an electrician.<\/p>\n

Wireless charging units are also more affordable than you might expect. At Box15, our 80mm Grommet Wireless Smartphone Charger<\/a> starts at just \u00a326.40+ VAT.\u00a0 Some wireless chargers have standard USB connectors<\/a> too, giving the user the opportunity to charge more than one device at a time, all from one discreet unit.<\/p>\n

Automatic pop up charging towers can also contain wireless chargers<\/a> too, giving the user a plethora of charging options, all from one socket.<\/p>\n

<\/p>\n

How do wireless chargers work?<\/h2>\n

Wireless chargers work by creating a magnetic field from which your mobile phone can absorb energy, harvesting it, ready to power the battery.<\/p>\n

Wireless charging isn\u2019t a new concept though \u2013 in the 1800s Nikola Tesla, a Serbian American inventor came up with a way to transmit energy through the air using resonant inductive coupling which creates a magnetic field between a transmitter and receiver.<\/p>\n

It\u2019s this same principle that makes wireless chargers work today. An induction coil in the charging unit creates a magnetic field which is then received by a second, smaller coil in the phone. This smaller coil harvests the energy and converts it to power the battery.<\/p>\n

It isn\u2019t just phones that can be wirelessly charged these days \u2013 the technology is of increasing popularity among medical implants such as pacemakers.<\/p>\n

The challenges of wireless charging<\/h2>\n

Wireless charging isn\u2019t a perfect solution \u2026 yet. It\u2019s still a little slower than cable charging, but this won\u2019t be the case for very long, as technology is constantly advancing and manufacturers of wireless chargers are continually striving to improve the speed of the charge.<\/p>\n

The other drawback of wireless charging is that, when placing your phone onto a wireless charging unit, you have to be pretty accurate as, if the transmitter and receiver are not aligned, the device won\u2019t charge. The introduction of MagSafe phone cases is resolving this. These phone cases magnetically snap to the wireless charger to keep the device being charged in the correct place.<\/p>\n

Of course, even with a MagSafe phone case, you still won\u2019t be able to charge your phone whilst having a conversation \u2013 but because it\u2019s so easy to charge your phone, you\u2019ll be charging your phone more often than you usually would, so it\u2019s less likely that you\u2019d need to charge your phone mid-call.<\/p>\n

Fitting a wireless charging unit<\/h2>\n

You can buy wireless chargers off-the-shelf and fit them retrospectively to a desk or a kitchen worktop or tabletop to give those using the area an easy station where they can top-up their device. It\u2019s quick, easy to use, and easy to install too, often taking power from a standard wall socket using a 3-pin plug.<\/p>\n
