I use a simple china brand 2600mah (actual rated is around 1000mah) for emergency can charge iphone to around 30-40% and small enough to put in pocket

total damage less than RM50

yoobao don't have 20000mAh if I'm not mistaken  sweat.gif
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  shakehead.gif

the capacity of iphone5 is 1440mAh. the powerbanks' capacity need to be reduced by around 30% (due to energy loss). do the maths yourself wink.gif

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...

my calculations are for Yoobao tongue.gif those other cina brand will get even worse.
maybe more well know brands like sony or eneloop will provide a better capacity loss per total capacity ratio rclxms.gif

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.

1000mAh should be charging it up to or more than 50% already since your battery is only 1440mAh..?

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.. biggrin.gif

4400mAh can charge for 2 times or maybe 2.5 for 10% to 100% IIRC
35% efficiency loss is possible, depending on surrounding factors and of course age of the powerbank biggrin.gif
