I guess you all know the new BL series phone is BL9000. And the battery will be 9000 mAh.But do you know how long will it take to make it fully charged?
Friendship tips: the output of BL9000 charger is 5V/5A.
OK, now let's guess

Well, let's see. 9Ah divided by 5A times 1.4 makes about 2 hours and 40 minutes. But if it is charged that fast it means that the battery is going to get HOT!

Also the charger must have thick cable to whitstand 5A current.

that's a good thought. I will test the temperature when charging

I guess it will be around 2 hours: 30% in 5 minutes is very fast. So after that I presume the charging will slow down. I guess 1 hour and 30 minutes is too fast. Then I have to see it and feel it for my self, but nobody ever sends me sample model.

Do that and let us know the result

The battery may be at its hottest somewhere around 70-80% charge. Then it will change from constant current to constant voltage charging and cool down a bit. Then again, a brand new good quality Li-Ion battery might not even heat up more than maybe 10 degrees.

Si mes calculs sont bons: 9A ÷ 5 = 1.4
Soit une heure et 15mn (1h15)
