@WickThe user can absorb various forms of energy, while removing it from the source, into their body and use it in various ways, gaining some form of advantage, either by enhancing themselves, gaining the drained power, using it as power source etc., either temporarily or permanently. But! For that permanently mean as stamina not as absorbing power of someone example to be able to use fire all of a sudden.

Limitations
Can't absorb self-generated energy.
May have limited range, including touch only.
May be limited to how much one can absorb.
Overloading: Too much power could result in incapacitation or death.
Overuse: Using more power than stored may exhaust the user after expending too much energy.
Under Loading: User may not be in a position to absorb power for some time, causing them to deplete their power supply. Attackers who know of the superpower may hide or wait until the absorber has little or no power and take them to a secure location when they are weakened.
