Mid-stage Pokemon like Charjabug rarely see competitive play outside of special formats. It's a waypoint on the road to Vikavolt, which is where the real potential kicks in. Works well under Trick Room. Only weak to Fire and Rock.
Charjabug's built to absorb hits, not race for knockouts. Physical bulk with Defense doing the heavy lifting. And the medium-fast 1M XP curve means it won't take forever to bring up, worth 2 Defense EVs.
Its body is capable of storing electricity. On camping trips, people are grateful to have one around.
From the food it digests, it generates electricity, and it stores this energy in its electric sac.

Don't skip the egg moves. Charjabug picks up Electroweb and Endure only through breeding, and both fill gaps the natural movepool can't. STAB runs through Thunderbolt and Wild Charge while Dark and Ground coverage and more adds range.
