Will this handle dashboard and panel removal on my car?

Yes — 3.6V is sized for interior trim screws and panel hardware. It's not a heavy-duty drill, so expect moderate resistance on fasteners larger than typical dash clips. Test on a scrap piece first if you're unsure about fastener size.

How bright is the LED, and does it come on automatically?

LED activates when the trigger is pressed, so you get light exactly when you're driving the screw. Brightness is designed to cut through shadows in engine bays and dark cabin areas — not a flashlight replacement, but plenty for close work.

Is a charging cable included, or do I need to buy one separately?

Only the screwdriver is in the box. You'll need to source a compatible 3.6V charger separately — confirm voltage and connector type before ordering a generic option.
