Can Fen earn more than one charge in a single turn?

The description for Fen’s Lightning Coil ability states:

When Fen delivers a fatal blow to an enemy, gain an energy charge.

If Fen defeats multiple enemies in a single turn, will he get multiple charges?

Methods of defeating multiple enemies in one turn include:

• Using an explosive weapon
• Shooting an explosive barrel
• Using a handgun that can fire multiple times
• Using equipment that counts as a free action

Simultaneous kills grant one charge only (2 deaths from a single explosion, etc); consecutive kills in a single turn however grant multiple charges (getting a kill with a free use sidearm and then with a primary weapon, etc).
