still cant beat this way
if want nice design, can buy are many type optical lens phone seller in garage.

been long time searching for this type of usb cable; short in length, coiled-type, and can transfer data, perfect as my ori powerbank cable replacement..

lumia 920

edit.. i put a small piece of aluminum foil on the pineng usb port.. so it shorts out two middle pin, and plug in the usb cable..

charges way faster now..

1. Check pins at powerbank port. Goal is to short the two inner pins.
2. Cut aluminum foil, fold it in two or three fold, so that not too thin or too thick.
3. Check the size, make sure doesnt touch two outer pins, check the width, no need too wide, ngam ngam touch two inner pins ok already.
4. Fold the end of foil so it become a hook.
5. Place and adjust the foil so it ngam ngam sit at the middle on the powerbank usb port. Use the hook to secure foil in place. Make sure dont let it touch outer pins, use plastic or sharp object to help u.
6. Quickly and carefully insert usb cable, dont connect to phone yet, see if ur powerbank turn on or not.. If not yet connect phone and powerbank already on, means the connection got problem, re do everything again.
if all ok, then can cucuk mini usb to phone, see the powerbank on automatically or not. If yes, then ok liao!

oh yes, keep extra aluminum foil in the powerbank bag or case. Just in case u cabut the usb and the foil loose or damaged dy. U can always fold new one any time anywhere.
update:
my phone usually get charged in 2.5hours using the usb wall charger, (with data and wifi always on cos im lazy to turn on/off)

using this hack, i tested just now, (wifi and data on) started charging at 28% battery remaining, finish 100% after 2hours (powerbank auto turn off like usual so no issue with powerbank after this hack).. so, 70% in two hours = 35% per hour..

i did use the phone while charging, view instagram, post this hack, surf fb and 30 minute chat, so the phoe is not completely idle during charging
at roughly 35% per hour while using the phone is fast enough for me..
i can get faster if i on flight mode lol..

the reason behind shorting both inner pins is to trick the phone so that it sense the charging device is not a laptop or computer,
if connected to a computer, the phone will only draw small current so it will not fry the computer motherboard.
so, only use shorted pins hack if u connect to powerbank or (1A or 2A) capable charger
dont use it at computer, if not ur motherboard will fried cos the current limit already removed.
