How to distinguish the safest and highest-quality solar power bank ? 1.We must look inside to understand deeply the three core installations. 2.A long lifespan -- After more than 500 times the charging and discharging it still keeps more than 85% of its capacity. 3.battery -- the decisiver factor of safety index, electric quantity and conversion rate. Why do we choose Li-polymer Battery(more expensive) instead of 18650? 1.A Li-polymer Battery is in smaller size than 18650 which with the same capacity. 2.Li-polymer Battery almost never explode, So it is much more safer than 18650 :The conversion Rate of 18650 is far more lower than Li-polymer Battery. Notice : Attention pleasse Rated power capacity is 8000 mAh ,but with the function of solar energy the power bank can be achieved charging itself and equipment at the same time to be 20000mAh output(max) . which means it could reach several times more than the rated capacity. Important reminders when you use the solar charging .it need in bright light the better Sunlight to charge the mobile power, do not Interrupted, at least 12 hours to charging .Solar energy conversion will some slow relatively , the solar power is about 220mah . therefore, it does not have significant reactivity . recommended that you use the usb DC charging and full power it anytime. about waterproo
