how long does it hold a charge when stored?

The information on the web page says- it’s suggested that the charger be charged every six months.

It comes 75% charged and it only took another hour and a half to get at 100% using a phone charger

Seems all the questions are regarding the JumpSurge 1200. But how long does it take to fully charge the 2000?

Hello, you can take a whole night to charge it fully. If you have any other questions, please let us know: support@topdon.com.

Can it charge the car battery?

Yes, only if the battery is 12V. If you have any further questions, please contact us at any time: support@topdon.com.

جهاز إستارتر (مشغل للسيارة) من شركة عريقه عالمية

الجهاز كمنتج ممتاز و فاخر من الآخر و خامة المواد ذو جودة عالية جداً ما شاء الله 👍ف وجوده في السيارة مهم جداً 👍و لا غنى عنه في حالات الطوارئ ك التعطل المفاجئ للبطارية و نفاذها 🪫🔴 🔴🔴 و لكن يجب الأخذ في عين الإعتبار مع أخذ الحيطة و الحذر ⚠️⚠️بأن بطارية 🔋الجهاز مصنوعة🏭 من مواد الليثيوم التي تتأثر بالحرارة المرتفعة أو ربما قد تتعرض لخطر الإنفجار🔥 لا قدر الله.🟢 و يفضل عدم تركها في المركبة لفترات طويلة و خصوصاً في مناطق الأجواء الحارة☀️
