The name comes from the superpower
Firstly, I suggest making the superpower less ambiguous. Just say he can create/manipulate electrical charge. Working from there, you can make up mechanisms on how certain things are achieved using that specific power, this will make your story more thought out, consistent, and certainly more satisfying to electrical engineers like me.
You can name him Charge.
How to use it
Now, to use charge or charge flow (current) to fly, there are lots of ways to do that and some may work better depending on the conditions.
For instance, if there is a conductive flooring he can generate magnetic fields (by rapidly moving charge back and forth). This will produce an opposing magnetic field in the conductive surface via eddy currents (the currents themselves are generated from the original magnetic field). This is how the real-life Hendo Hoverboard works. He would likely use this method to glide around his apartment without generating ion wind.
Where a conductive substrate is not available electrostatic levitation is another option, as pointed out by Dan Smolinske. This only requires that charge be concentrated on himself and nearby objects. You can see a small scale example of this with two balloons repelling each other. Again, this provides a small amount of force normally, but could be feasible. Most likely he would use this to statically levitate objects (sounds like a nice way to sleep).
While still in the atmosphere, electrohydrodynamic thrust can be generated to provide lift (used by devices like the ionocraft, as linked by user3082). However, since he can manipulate charge directly, there is no need to have an apparatus for making ions, he can just add charge to molecules directly. Adding a concentrated opposite charge some distance away will act as a collector for the charged particles. Its position relative to the average center of the ions will define the thrust vector. As the ions move to the collector, they bump into uncharged air and generate force perpendicular to ion flow. The force it produces is:
$$F = {{Id}\over{k}}$$
$F$ is the resulting force, in Newtons
$I$ is the current flow of electric current, in coulombs per second (charge flow rate, this is the ions flowing to the collector).
$d$ is the air gap distance between the ions and the collector, in meters.
$k$ is the ion mobility coefficient of air, in inverse teslas (Nominal value $2\times10^{−4}$ $T^{-1}$).
So, if your hero weights 800N, and you have a quarter meter air gap (a large gap might be required to avoid dielectric breakdown), you need to have 640 mC/s flowing. This is just to hover. Add more flow for more force. Changing the position of the point collector will change the direction of thrust. There will be a lot of wind coming off of him, don't use this in places where someone is building a cardhouse.

Basically, by distributing the ionization surface and creating a point collector, it will look similar to a hall thruster.

There are more options if you allow him technological aid. He can control charge and manipulate it, basically, he can power any electrical device. This is essentially Iron Man's power, because of his Arc Reactor he can power everything on his suit.
The biggest drawback to most electrical forms of propulsion is storing the energy to run them. But your hero can have electrically powered jet engines or a suit with motorized propellers that are powered by him directly.
How to break it
To disable eddy current hovering, the conductive material needs to be negated. If its broken up or has its resistance increased it will be less effective.
Electrostatic levitation is kind of a landmine. Adding a significant amount of charge to something means it's waiting there, desperate to get rid of that charge. Think about the shock you get from a door handle as your body discharges into it. It's incredibly significantly worse than that. So, to break this, just give the object a low resistance path to an uncharged (or oppositely charged) object. Some fine conductive thread can short out hovering items.
Breaking electrohydrodynamic thrust can be done by adding conductive material to the air. This would short out the field between the opposing charges. For instance, the super (or regular) villain could launch some chaff at the hero in flight and mess him up pretty badly. Alternatively the air can be removed, but the hero will probably have other problems in that case.
