Product description

CHARGE IN-CAR WITH ENGINE OFF? NO PROBLEM!

Solve it with our new ECO-WORTHY kit! Option 1: Use the upgraded OBD-II accessory for battery maintenance—supports charging when engine off. Option 2: Keep the classic alligator clip design for direct battery connection.

WHY WE ADDED THE BRACKET? SOLVE WIRING ISSUES WITHOUT POWER LOSS!

For 10 years, our standard kit faced frequent wire length complaints. Longer wires mean current loss, causing noticeable power drop. The new bracket solves it: same wire length, better sun alignment (ground/console/roof), no power loss!

WORRIED ABOUT OBD-Ⅱ INCOMPATIBILITY?

OBD-Ⅱ has been mandatory for new cars (North America since 1996, global rollout from 2001) and nearly universal post-2008. If your car was bought after 2008 (excluding Volvo), ECO-WORTHY’s OBD-Ⅱ option outperforms the old cigarette lighter!

WHAT CAN THE SOLAR BATTERY MAINTAINER DO FOR YOU?

Experienced car owners know: leave your car unused for over 10 days, and the battery may die—costing you time and money for a replacement. This solar kit is your ultimate hassle-free solution for this exact issue.

FOR EVERY CAR THAT SITS IDLE LONG-TERM

RVs of retired travelers, backup vehicles of multi-car households, prized classics of vintage car lovers, “migratory cars” with out-of-city plates, weekend getaway rides for urban workers. A single solar maintainer keeps power flowing year-round!
