all made in china, and LiPo battery low quality one will get swollen very fast.

good quality LiPo is what u use inside your phones, tablets, cheap LiPo is like those explosive battery type, no proper QC one.

go for original powerbank bro.

I doubted it uses Li-polymer battery.
The shape of the powerbank is same as pineng pn913 and the cost for Li-po is higher than 18650 battery.
The advantage of Li-po is they can be shaped into different size and slimmer.
What for you want to shape the size same as 18650 with higher cost ?

The fella i bought from said its original.

I just bought it less a week ago.
Very dissapointed.. Can only charge less 3/4 for Galaxy Tab 8.0.. T_T T_T
Note:
Galaxy tab battery 4,600mAh..

some rough calculation

3/4 of 4600mAh battery size = 3450mAh

powerbank actual capacity = 3450 * 1.5 times
= 5175mAh

so the actual powerbank battery size is only 5175mAh, as claimed to be 30,000mAh

yup i also just buy it. very suck money haiz

Customer spoilt powerbank.
open up dunno what cells inside......buy cheap but ended up spending more.

thanks for the great info..

WAAAAA..... inside macam will keboom eh.....

Powerbank saya hehe..

Is that a LiPo from RC planes? What converter did you use?

Yeah..ori got 1 yr warranty.

only buy yoobao come from malaysia local distributor

so what is the best choice for powerbank which is compact and have high storage of battery life?

this 'pisen' is same with 'piseng' ?

How many charging cycles can a power bank last?

Depend on ur capacity u purchase.

no idea about the 'piseng' lo
cells inside dunno what capacity also

if 1A = 1000mA ..

why is power bank rated in mA. ???

why 2200mA .? is it not same as 2.2A. ??

we dont say 1200meters.. . = 1.2km...
