ALLPOWERS 12V 18W Portable Solar Battery Car Charger For Car Battery Automobile Motorcycle Boat

Description:1. Batteries Naturally Discharge: - Automotive batteries naturally discharge when not in use.2. Peace of mind: - Vehicles that are used infrequently or do short trips are prime candidates for discharged batteries.Safety Protection: The solar panel is FCC, RoHS, CE certified. Short circuit and surge protection technology keep you and your devices safe.3. Battery life is shortened if it is not kept charged: - A 12V battery that is not correctly maintained above 12.4V can suffer from sulphation. Sulphation is the number one cause of battery failure, something not covered under warranty as it is not a manufacturing defect.4.Easy to use: Just plug this solar charger into your vehicle's 12 volt lighter socket and position the panel to pick up the most daylight possible. Or, if you prefer, use the included alligator clips to connect it directly to the battery. (you can mount this solar power panel on your windshield with the two suction cups or fix it on the sun visor with the back strips5. Modern vehicles have a small but constant battery drain: - Modern vehicles can now have upwards of 30 body control modules (computers), plus alarm systems, immobilisers and lock monitoring. These units all consume valuable electricity from the battery (up to 0.02 of an amp per hour). This means that over the course of a week or two with no or little vehicle use the battery can become discharged.Feature: Optimal Power(Pmax.) 18W±0.25W @1000W/? AM 1.5 25?
