Quote from: crazyguy on August 11, 2016, 03:50:57 amuse a large heat sink will increase the size of the powerbankWell it's not so large, the width is only 14mm (0.55 inch) and the height 6mm (0.23 inch) !And I was thinking I could trim its length according to the hot surfaces it has to be glued on on each side of the PCB ...Quote from: crazyguy on August 11, 2016, 03:50:57 amI don't think you can purchase this demo board anywhere, send a email to the IC company maybe they would be kind enough to give you a copy for testingThat's what I'll do.Is Changdiantou a distributor only or the original IC company ?Apparently, their website is about video rentals ... ?!?

BTW, there is a BQ24295 that does the same thing, it can only boost to 1.5A, but it can charge at 3A. It is one of the rare USB OTG ICs that have a separate boost output other than charging input.
BQ24195 can boost to 5.1V@2.1AI2C Controlled 2.5A/4.5A Single Cell Charger with 5.1V 1.3A/2.1A Synchronous Boost Operationhttp://www.ti.com/product/bq24195
chongdiantou is a forum interested in charger, they are not distributorthe IC company name is INJOINIC Technologyhttp://www.injoinic.com/their website saysFor English Datasheets, please mail to SERVICE@INJOINIC.COM
the IC company name is INJOINIC Technologytheir website saysFor English Datasheets, please mail to SERVICE@INJOINIC.COM

attachments is the datasheet of IP5318. IP5318 is a QC3.0 soc that has passed qualcomm QC3.0 verificationbut how to upload attachment bigger than 1MB

IP5318 is a QC3.0 soc that has passed qualcomm QC3.0 verificationbut how to upload attachment bigger than 1MBHello 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 ?
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.

please give me your mailing address.and you can also buy a powerbank using IP5209 IC from amazonsuch as:https://www.amazon.com/ROMOSS-20000mAh-Portable-External-Recharger/dp/B01DM4EYO8/ref=sr_1_15?ie=UTF8&qid=1470986008&sr=8-15&keywords=romoss+powerbankhttps://www.amazon.com/20000mAh-Flashlight-Portable-External-Battery/dp/B01AAUFTN2/ref=sr_1_2?ie=UTF8&qid=1470985337&sr=8-2&keywords=arun+powerbankhttps://www.amazon.com/mobile-power-ARUN-Universal/dp/B01D4F07X2/ref=sr_1_8?ie=UTF8&qid=1470986225&sr=8-8&keywords=arun+powerbanketc...
