I wanted an external battery charger that is powerful but yet portable enough to carry around in the pocket. I already have Yoobao 11200 mAh model - even though its very powerful but to big to carry around.
I think I have found the perfect one which is easily available and good quality - YB622 from Yoobao (USD 31.89 with free shipping via eBay Malaysia).
Shipped on 25 Dec and arrived on 10 Jan.
About 16 days including the Xmas and New Year's holidays!
Reasonably fast for free shipping!!
NOTE: There is another way to get this at USD 36.90 from Dealextreme.
