Brand:DUDAO Model:K6PRO

Selling point:

1 usb cable for powerbank charging

no need to carry extra cable

Charge 5 devices together

(but total power very low,dont suggest do like this,only for emergency use)

Power bank battery capacity:10000mah

Battery:quality li-polymer battery,recycle time more than 400 times

(after 400 times recycle,more than 70% power remains)

Power bank rated capacity:5850mah(5V/2A)

What is rated capacity and why is lower than 10000mah?

Currently most powerbank battery is 3.7V

So power bank battery 10000mah means 10000mah/3.7V

But phones all need 5V to make itself be charged

Before charge phones,need rise 3.7V to 5V

So rise to 5V,10000mah/3.7V is 7400mah/5V,7400mah only theoretic data

during rising 3.7V to higher voltage,will have heating

Heating means power loss,so real capacity under 5V is less than 7400mah

And some expensive powerbank use super quality circuit makes the power loss

much less,like Anker

Anker 10000mah powerbank rated power under 5V/2A may up to 6700mah,is super

But one price one quality,our powerbank quality is reliable while keep price cheaper

so our power bank circuit cant compare with that of Anker

So this powerbank rated power under 5V/2A is 5850mah

USB A Output:5V/2A max

USB B Output:5V/2A max

Micro usb cable output:5V/2A max

Type C cable output:5V/2A max

Lighting cable output:5V/2A max

Charge more than 2pcs devices together:total 5V/2A max

So charge more than 2pcs phones together,charging speed will be lower

Note:5V/2A max not means always charge phone with 5V/2A

different phones with different charging current,and even for same phone

charging speed is different when phone battery remains different power

Micro usb/Type C port input:5V/2A max

USB Cable input:5V/2A max

Please dont charge powerbank while powerbank is charing phones

Please only use micro usb or type c port or the usb cable to charge powerbank
