i just bought it at Viewnet for rm35. and also they tell me if i add on rm3, they can just switch 1-1 if anything happens to the power bank in 12 months. no repair needed. if rm35, if claim warranty have to wait for repair. i find it worth it rm3 for whole 12 months so, i bought it for RM38 nett.

ip4 battery capacity rated at 1420mAh. That new one. My battery already degrade to 1340mAh.
Beli kat lowyat plaza 3rd floor la. I dun know the shop name but their shop is the biggest computer accessories shop at the 3rd floor.

bought a philips powerbank (7800), did a full charge. Can only charge my HTC one (2300) for 2 times (from 10% to 100%), and last charge only went from 10% to 30%.

So the powerbank only holds <5000 mah...its way too low from the advertise 7800.

Should i take it back the shop for 1-1 or will this improve after charging few more times?

anyone can advice if this is normal? 

I recently bought a new power bank. its says 10k MAH. But only manage to charge 2 times full for iphone 4. It means i get conned ?

looking for a quality power bank??

pm me if u interested.

how much for Anker Astro 3E 10000mAh External Battery (Black)

Yes. Pineng original is a good brand... the reason why we are not selling it is there are too many sellers around as well as fake / imitation brands. Too tired to compare already. Those fake sellers are telling everyone its the same, just from different sources.. haiz.. faced the same issue when we are selling original yoobao last time. Now focus on selling JOHOYO which is assembled in Malaysia.. No imitation at all.

ah, no1 told me this. juz bought from viewnet at rm35. nvm. i believe viewnet wont sell imitation product...cross finger...there's so many brand available at viewnet, even kaspersky 

already checked the serial number. its a genuine product hehehe.

Perfectly normal. 7800mAh is the maximum capacity of the power bank. But since most power bank are using 5W and phones are charging input are 3.7w, the energy will need to be converted. Normally we take only 80% of the said maximum capacity. So for a 7800mAh, 80% would means only 6240mAh useable. Plus some energy lose due to standby.. It comes to around the number of time claimed by you.

Hope this explains...

Thanks! i'll try to fully charge/totally drain few more times..see can improve a bit or not

How do u check whether its genuine serial number? I heard from our supplier that the original serial number can only be check once. After that it will become invalid... Anyone can comment on this? Don't really trust statement from china suppliers. Prefer direct testimonials from user

1st time you check it will say that it is a genuine product from shenzen yoobao bla bla bla. 2nd time u check it will say that this serial has been check on 'date and time' the 1st time u checked

I'm using Yoobao. So far so good no issue for me

Higly recommended
