A wireless charger is a device that transmits electric energy through magnetic (radio) waves.
The basic principle behind the function of the device is explained in either 6th or 8th grade physics: electrons traveling through electric wires or other conducting objects generate magnetic forces perpendicular to the flow of electric power and any magnetic field perpendicular to the wire generates electric energy in the wire. By twisting a wire into a coil, the magnetic field is then concentrated and focused, thus forming an inductive coil (a different name for electromagnet). by placing two of these coils next to each other, alternating current electric power is transferred from one coil to the other. Another place where this phenomenon is found is in the antennae when electric signal is transferred from one antenna to the other one (or more). The distance and efficiency of energy transfer depends on the shape of the antenna and wavelength (frequency) used.
This technology is used in TV and radio broadcast, cellphones, wi-fi, power Transformers (big ones supplying power to homes and small ones in power bricks), etc, etc...
The wireless chargers are usually flat pad-looking devices (the power transmitting antenna) and can be used to charge most common portable devices like cellphones and mp3 players. The power receiving device would have to be modified (the power receiving antenna) or specifically designed to operate with a wireless charger. The wireless chargers usually operate in micro-wave frequency and therefore need to be in close proximity to the device being charged.

Can you use a 12 volt charger to charge 6 volt batteries in recessive situation?
That really depends on how the charger is made. What would likely happen is that the charger would try to deliver more current than it is designed to. The result would be either a blown fuse or diodes in the charger unless it has protection circuits in it. One thing you could try would be a current limit in series with the charger output. A headlamp in series could work to limit the current to somewhere around 3-6 amps and prevent having an overcurrent situation on the charger. Dad calls the light bulb current limit a "rubber fuse" It will take longer to charge that way and you really need to check the battery voltage often making sure not to exceed about 6.75V Be aware that with this method there is no way for the charger to sense that the battery is fully charged. It will continue to try to push to around 14 volts which will never happen until you cause an open cell in the 6v battery. charger + to headlamp bulb, other side of bulb to battery+ B- to charger- That could get you out of a pinch but you really need a charger designed for 6v charging.

Will a DS charger always work?
Define always work. Everything will eventually wear out and break. The question posed is the same as will my DS always work. The answer there is no. Is your charger broken?
