soon gonna get 2 Xiaomi 16000mAh , waiting for my bro in law to order it via online , both of us gonna buy the same powerbank

Actually it is about there.
Normally those China powerbanks (including Yoobao) have efficiency of 65% only due to loss of energy in heat, resistance in the cable, etc, etc.

5200mAh X 0.65 = 3380mAh of usable power

3380 / 2300 = 1.47 times

So yeah it can only charge your phone around 1.5 times

Xiaomi not mistaken claiming efficiency of 90%, but I not sure how true is that as I didnt use Xiaomi powerbank before

Thinking of getting the extra powerbank for my trip next month. Come across with this sellar:

http://www.lelong.com.my/free-original-pou...7-01-Sale-I.htm

anyone has bought from this seller? the price quite cheap and claimed sell original pineng.

go for 16 000mAh xiaomi bro

go for 16 000mAh xiaomi bro

good price 

original ?

Pirated powerbank izzit
10000mAh should be able to charge at least 2 times

Can consider AUKEY powerbanks

Considered cheap already as it is equipped with Qualcomm Quick Charge capabilities.
The cheaper powerbanks do not have Qualcomm Quick Charge.

Pineng powerbanks are okay actually, just make sure you buy the original Pineng and not the pirated

what do u aspect from pasar malam , surely they will sell pirated powerbank , cheap price to good too be true .. but as long as it works for you , more then okey

Nowdays those pirated looks like original , hard to detect ori or not , thats why i go for MI powerbank , order direct from them ...

yea safer

if you don't need dual USB port, why don't buy from XiaoMi ?
100% original if buy from XiaoMi website, but is more expensive which cost RM 59 for 10k mAh

If buy from its website definitely original
As for stock, I think got stock since it no longer sell like hotcake like last time
