also known as inductive charging. Chances are you already use this kind of

wireless charger

if you have ever used a rechargeable electric toothbrush or shaver

for simplicity's sake, let's consider the pad

and wireless charging enabled device

are special magnets. So both produce a magnetic field.

Once those fields cross and energy start to transfer from one to the other.

Some phones have this special magnet built-in, like the Nexus 4

and Nexus 5 but some you can actually put in

like this wireless charging battery card adapter for the s4

There are a lot of standards out there

for wireless charging but most use the Qi standard.

So if your phone or any other device can wirelessly charge,

make sure you know what standard its using so you don't buy the wrong

charging pad. All the different wireless charging pad we sell on our site

are compatible with Qi enabled devices. I'll put a list of

Qi enabled phones in the description below. So I have the

S4 and the Qi battery card adapter here. Wireless charging does not come built-in to the S4

so you have to get this battery card adapter which comes with this

charging pad for 50 bucks on our site. To install this card

first, power off your phone,

then remove the battery cover. Align the battery adapter

with the contacts located above the battery and then put the cover back on.

Plug in the charging pad

Finally put the phone in the middle the pad to start charging.

If your phone does not need a wireless charging adapter

the ECO and UFO charging pads

are good alternatives with a lower price tag.

OR Samsung sells a special battery cover

that has this battery card built-in for around 40 bucks

but this price does not include a charging pad.

All these chargers are available on our site. I'll put links in the description.
