ソーラーパネルを直射日光が当たる場所に設置してください。できれば、最大限に光が当たるように角度を調整してください。
SAEケーブルまたはワニ口クリップをバッテリーに接続してください。
日中は放置して、受動的に充電させます。
LEDインジケーター（ZOUPW製パネルの場合）を使用して、充電状況を監視してください。
🔋 急速充電ではなく、維持充電に最適です。

通常、アンペア数とバッテリーのサイズにより24～48時間。

Flexible solar panels excel in ultra-thin, lightweight, and bendable applications. They are best suited for curved or weight-sensitive surfaces such as curved RV roofs, teardrop campers, Jon boats, car windshields, agricultural vehicles, and curved roofs. Low-wattage versions are also perfect as trickle chargers for vehicle battery maintenance.

No. This flexible trickle charger series features a built-in smart mini charge controller and anti-reverse diodes to prevent battery overcharging and night-time discharge. It comes fully equipped with alligator clips, O-ring terminals, and car charger cables for direct 12V battery connection.

They feature a dual-layer flexible fiberglass substrate inside that prevents scratches on vehicle paint during installation. The outer ETFE coating provides dustproof, wear-resistant, and heat-resistant protection for long-term outdoor reliability.

It includes a complete accessory kit: 20W/30W flexible panel unit, 3.28ft alligator clip cable, 3.28ft car charger cable, 3.28ft O-ring terminal cable, 4 carabiners, 2 windshield suction cups, and a storage bag. You can attach it directly to windshields using the included suction cups.

When vehicles are parked, security alarms and onboard electronics slowly drain the battery. A trickle charger provides continuous low current during daylight to offset self-discharge and parasitic draw, maintaining 12V battery health.

Yes. It includes a built-in smart controller and anti-reverse diodes. It prevents night-time reverse discharge and automatically cuts off high current when full to prevent overcharging, making continuous connection safe.

Yes. High-sensitivity monocrystalline cells generate low micro-currents even in overcast or low-light conditions, sufficient to maintain minimum 12V activation voltage and prevent sulfation.
