About This

• Efficient Battery Charging — Our 20W 12V solar battery charger combines A+ high-efficiency monocrystalline cells, low-iron tempered glass, and a smart controller (built-in intelligent chip) to deliver up to 20–30% module efficiency and consistently faster charging, helping your battery replenish power quickly
• Wide 12V Compatibility — The kit comes with plug-and-play alligator clips and O-rings for quick hookup This fully automatic, maintenance-free smart 12V solar panel works with LiFePO₄, Li-ion, AGM, SLA, GEL,FLD, EFB, and MF batteries, ideal for car, RV, boat, motorcycle, camper, lawn mower, trailer, and water pumps, and electric fences—keeping parked equipment topped off and preventing battery drain during storage
• 3-Stage Visible Charging — Stay topped off safely without babysitting A built-in intelligent chip auto-switches Bulk → Absorption → Maintenance—fast fill, then gentle maintenance Three status LEDs show the stage at a glance, while 6-in-1 protections—anti-backflow (reverse current), over-charge, over-voltage, over-current, short-circuit, over-temperature—keep charging safe and help extend battery life
• All-Weather Durability — Stable output in extreme conditions Full-potting and IP68 weather sealing prevent moisture ingress and protect the electronics, delivering steady current from 14°F to 158°F (-10°C to 70°C) Low-iron tempered glass with a corrosion- and rust-resistant aluminum frame is built for long outdoor use—up to a 25-year service life—while corner guards help absorb bumps for added drop resistance
• Complete Kit & 24/7 Support — What’s in the box: solar panel ×1; charge controller ×1; 360° adjustable mount ×1; alligator clip cable ×1; O-rings ×1; mounting hardware kit ×1 — install in minutes The included 360° mount lets you aim at the sun to maximize daily solar intake and improve charge yield Backed by 24/7 customer support and a 365-day warranty for peace of mind
