Hello Injoinic,

Thanks for joining the EEV community and posting in this thread ("DIY cheap powerbank (technical suggestions R welcome !") which I am the OP.

I suggest that you COMPRESS the size of your attachments, thus allowing you to post them here.
Another suggestion is to host the .PDFs somewhere in the cloud (for example in DROPBOX or GOOGLE DRIVE) and give us a public share link here !

Could you also provide us with the IP5109 and IP5209 datasheets ?

thanks
please download IP5209 and IP5318 datasheets @ http://www.injoinic.com/doc/pdf/IP5209%20datasheet%20v1.0_en.pdf
http://www.injoinic.com/doc/pdf/IP5318%20datasheet_en%20V1.0.pdf

For Your Information:
IP5109 has been upgated to IP5209 with pin to pin match.
IP5209's efficiency is higher than IP5109 @charger and booster.
And IP5209 has more featue such as DCP and BC1.2 support.
but his price hasn't changed.

Thanks for your links !
Two questions :
#1 have you already designed an IP5209-based prototype board like this one (Lithium charger and 5V booster) ?

#2 if yes, how is it possible to get samples for further testings ?
