Charges via the cigarette lighter socket and shows battery status with LED indicator.
Some vehicles — particularly those with sealed battery housings or batteries mounted in unusual locations (boot, under seat) — make it inconvenient to attach clamps directly. The Comfort Indicator Cig Plug charges through the cigarette lighter socket instead, while the LED indicator shows battery status on the dashboard. A green light means the battery is healthy — a useful daily indicator even when not charging.
vs Eyelet: The eyelet provides a direct battery connection which is slightly more efficient. Use the Cig Plug when direct battery access is difficult, or when you want a permanent dashboard LED indicator.
