Wireless electricity exists now. Have a pile of cell phones and iPods to recharge? Just drop them on the recharging platform, no wires needed. Ditto for electric power tools.
There are three ways to do it. Radio-frequency Harvesting converts electricity to radio frequencies, sends them up to 85 feet, then converts back to electricity. Magnetically Coupled Resonance can power an entire room from one device, no wires needed. Inductive Coupling sends the power a few inches onto the recharging table.
Most important, these technologies exist now. I’ll not miss the tangles of cables and separate charging stations for every device.
