USB POWER BANK // PORTABLE POWER SUPPLY

ok, i came to a conclusion that im going for a passthrough/charge through capable powerbank.

Zendure brand seems promising. but cant get it at the moment

This UPS/passthrough/charge-through powerbank that comes close and can be found in shops here is Xiomi.

the brand also has a look out for a not genuine powerbank and doesnt have all its glory,which i think the real thing is a good brand but what comes to mind is, is it ok?

from reading this blog

http://www.the-area51.com/2014/09/xiaomi-mi-power-bank-10400-review.html

a turn on haha

but this part of the blog;

" Pass-Through Charge is Supported

Another good thing about this Power Bank is that it supports pass-through charging, this means that you can simultaneously charge your phone and Power Bank. The Power Bank will pass the charge to the device and once the device is 100% charged, it will charge itself.

This type of capability is seen in top brand Power banks which are quite expensive as compared to the Mi Power Bank.  "

what comes to mind is, from its spec, http://www.mi.com/en/pb10400/#params

" Power sourceDC 5V

• Input voltageDC 5.1V
• Input current2.0A(TYP)
• Output current2.1A(TYP)
• Rated capacity3.6V/10400mAh(TYP)
• Charging time5.5 hrs with 5V/2A plug and standard cable
• 12 hrs with 5V/1A plug and standard cable "

its output 2.1A but 12 hrs with 5V/1A plug and standard cable, i dont get that part is it saying the output is realty just 2.1A and depending on the hardware thats need charging if it can filter amps

shabaz, is this safe for my raspberry pi2mB?if the pi2mB can filter how many amps it needs just like nokia's python script for amp input and the iphone required adapter power source.

If it can, 1 more thing comes to mind when this type of tech capabilities power bank is " 100% chanrge" do you think it draws 2.1A or less and safe for the pi2mB. or 2.1A is too much for the pi2mB

or its all jibberish and just go for a powerbank that has 1A printed on the usb port??haha

MOST powersupplies provide a voltage and the device you connect can use whatever it wants in current. (amps). Up to a certain maximum of course.

That 2.1A is such a maxium. So as long as you provide the 5V to the 'pi it will use whatever current it needs (as long as the 'pi doesn't need more than 2.1A, but the 'pi is specify to require at most 700mA (=0.7A). )
