Get the one that size fits you the best la. Ahdoi.
TBH, if u don't mind carrying around something the size of a briefcase, someone's gonna recommend you a 5kAh battery.

haha... nice answer..

Actually what I'm keen to find out is the effectiveness of these Powerbanks in charging our SGS2...

For example, if I have a 4400maH Yoobao, does it mean that I can charge our SGS2 1650 mah (from zero to 100%) two times...ie 1650 x 2 = 3300maH... still less than 4400mah.

Does it work like that?

Or a fully charged 4400maH Yoobao will never be able to charge our SGS2 1650mah from 0% to 100%?

Thanks for any advice from those who have experience with these Powerbanks...

waa.. uncle.. u alwayz have the answer..

On a rough level, won't run too much right.

So even if you wanna be prudent, 4400mah would give you slightly more than 2x of your current usage. If that's enough for you, get that one. If not, go for higher one.

Just do the math and save some buffer for inefficiency etc, just in case

It works that way, you do have to minus off some loss from operation of the phone to the heat generated.

But generally yes, your calculation is for layman.

thanx for the tipss.. will consider it..

I love my casemate, been using it since day 1.

Anyone tried this one ? 20000mah

20k the price must me

The charging time must be o_O
if out of battery just before going onto a long trip, gg.

this has been recall back by Power Cellular Accessories Supplies Sdn Bhd

any insider news for the reason to call back? explode or?

seriously we nid those external charger because it is portable enough to be cary around but that@@ who will even wan to carry one of this when he is travelling==

Well on a day to day basis, if you're not one to carry a bag or whatever then yeah, probably you won't want to be luggering it around (don't think these are actually pocketable)

But say you go on a day trip. And you need your phone for GPS and browsing. And you go a full day. Then yeah, you'll definitely not mind luggering it around then

i would say even a 11200 mAh Yoobao is enough to hold ur day trip, taking that is like extending ur wall plug from home , but anyway the more the better is what human prefer haha

Yeah. It's a leceh solution I'm not a fan of, but it helps.

Those iphone clip on battery packs would be nice

Hey there, I'm looking for cases like the Barely There case by Case Mate but with more vibrant colours. Any suggestion?

Thank you guys for all the replies on the Powerbank battery.
