[Expired]Anker MagGo 5000mAh 7.5W Magnetic Power Banks 2-pack

回复 @匿名用户 : It's about energy calculation. The total energy is 18.5WHr, with a 3.7V 5000mAh battery cell. At 5V output, it's only 3700mAh... and that's the theoretical maximum assuming 100% circuit conversion efficiency... 就是算能量啊，总能量18.5WHr，电芯3.7v 5000mah，输出5v就只有3700mah了啊……这还是电路100%转换率前提下的理论最大值……

: How did you calculate that...? How can 5x3.7/5 reach 4000mAh...? Even with a 100% conversion rate, it would only be 3700mAh... 你这咋算的……5x3.7/5怎么能到4000mAh……100%转换率也才3700mah啊……

: Anker is pretty decent, how could the quality be so bad? Anker还行呀 怎么会质量这么差

: Didn't you contact customer service? 没有找售后？
