Bro, since you are providing a microusb cable, I presume it charges with a microusb port?
How do you switch to 9v and 12v ? How many amps output does 9v and 12v give? Dies varying the number of cells, for example 4cells of 3000mah, give nominal 12k and real output of about 9k? Thanks for responding. |

QUOTE(CyySky @ Nov 26 2013, 12:39 PM) You can use microusb to charge your phone using powerbank's usb port. So you are using a non-microusb cable to charge your powerbank?When charging this powerbank. It can draw upto ampere reach 2A,it came with own usb cable. Normal microusb cable came with 0.3-0.6A not enough for charging need. Press button for 3 second to switch voltage to 9v press again to 12v.During 9v 12v output the usb will shutoff to focus power. 9v 1.5a 12v 1a In my showcase,this the actual 3000mah cell performance is 2600mah. Because it is special 4.35v rated battery. And the casing charge normal 4.25v for major compatible all 18650 cell. So the convert lose in ratio is 12075mah:15600mah about 77% of the capacity.  Could you show pics of the ports on yr pb and your charging cable as well thanks. |

QUOTE(CyySky @ Nov 26 2013, 02:50 PM) [attachmentid=3740915] Just curious, there are microusb cables rated for 2A or 3A, are there problems using those? I really like the idea of your PB and allowing the user to vary the capacity simply by reducing batteries, but I strongly prefer not to carry ANOTHER cable to charge the PB.[attachmentid=3740919] Two cable included. One for charging cable in picture. Second cable for 9v 12v output to router size round head. Will upload second cable image later.Second cable I put at store. I suppose you could test out the high current microusb cables, since Note 2 and Note 3 already use it, and such quality cables are also readily available. |

QUOTE(CyySky @ Nov 29 2013, 01:30 AM) You may find "galaxy charging current" app to see actual charging current to reveal the true. Actually Note 3 CAN use standard microusb 2.0 cables. See Note 3 thread post 3 ( I was formerly TS and published all the stuff there )The original cable of s4 or note 2 may vary from 0.8 to 1.7 ampere. Note 3 can go higher ampere because it came with usb 3.0. Then it defeat the purpose of having one cable if using usb 3.0 since the less device using. Your opinion is good. And I have 4 cell type of powerbank casing that can charge using microusb .Will sell up on request. And if you want this with 6 cell casing with microusb I can special modify one for you. Pm me if u really want it. Thanks for your comment . https://forum.lowyat.net/index.php?showtopi...post&p=64618115 I am also familiar with the GCC app and have used it for more than a year already from Note 2 to Note 3. I also usually carry 2 microusb 2.0 cables with me for charging, so it's more convenient instead of worrying about a potentially lost non-standard cable. I suppose your charging cable is the 3.5mm type used by normal AD/DC selectable voltage converters right? I do know how to make one but it's still a hassle. |
