QUOTE(l4nc3k @ Jan 18 2013, 10:42 AM) yoobao don't have 20000mAh if I'm not mistaken YEA agree what you said the usual ones from yoobao are 13000, 11200, 6600, etc. the max i've seen from yoobao is 13k. the 20k one should be counterfeit product |

QUOTE(l4nc3k @ Jan 18 2013, 10:54 PM) the capacity of iphone5 is 1440mAh. the powerbanks' capacity need to be reduced by around 30% (due to energy loss). do the maths yourself I would say this is partially true only for unwellknown brand power bank, my energizer XP4003 rated at 4000mAH and I can fully charged my iphone 5 about 3 times....3x1440mAH=4320mAH which exceeded the rated capacity of the powerbank itself....somemore energizer is the only brand which currently offering 3 years warranty... |

Have you came across advertisement from Voltaic which always appear on any site you visit ?
They have power solution for most of us to use solar http://www.voltaicsystems.com/ They have range of power bank that you can charge via wall plug or solar panel. And the biggest one can charge your macbook too. Since their bags are so ugly and bulky, we can just buy the power bank http://www.voltaicsystems.com/10wattkit.php Or if you like DIY we can buy their panels and screwed it to our bag. Each only measure 8"x 4" so not that big. we need 3 to charge the biggest powerbank. http://www.voltaicsystems.com/kits.shtml#guide Lets go green people! LOL *unfortunately voltaic do not ship to malaysia. so have to find 3rd party shippers like usunlocked, vshub, etc to bring to malaysia. This post has been edited by chokia: Jan 22 2013, 09:39 AM |

Well in Yoobao's website I once saw that the efficiency loss can go up to 35% (I hope I read it wrongly)Anyway I have ordered a YB Magic cube 4400mAh, should be enough for 2 charges. Didn't need that much of power. Just as emergency. There is some thread selling 12000mAh china brand at RM70 up. My sister used it and it could charge her S3 for 4 times (she said). Sound OK for that price.. |
