1000mAh should be charging it up to or more than 50% already since your battery is only 1440mAh..?

Well in Yoobao's website I once saw that the efficiency loss can go up to 35% (I hope I read it wrongly)

Anyway I have ordered a YB Magic cube 4400mAh, should be enough for 2 charges. Didn't need that much of power. Just as emergency.

There is some thread selling 12000mAh china brand at RM70 up. My sister used it and it could charge her S3 for 4 times (she said). Sound OK for that price..

Charge it in front of aircond blast to reduce environmental heat influence
Twice is more than enough to last my phone until I reach home. And I don't need heavy batteries in my bag

The one you described was the "original local" set obtained from the sole distributor. There are also some real genuine "original china" set produced by yoobao and imported straight by sellers without modifications. Yoobao also provide OEM/ODM services to produce for other companies. Of course they are other fakes too. Some prices quoted are too high I think.

Power banks should have very high profit margin. So if you can get a way to import original yoobao directly you may be selling at a real low price while being unbelievably genuine. Judgement is up to buyers afterall. Seen some selling at really low proce and customers proved them genuine from yoobao china.

If weight is a problem, can consider smaller mAh so it's less heavy. Mine is 4400 mAh magic cube. Love the design and the size, and yes I am a lazy person to bring heavy things
The only downside is that the magic cube comes with glossy finish so it now has smudges all over it.

2A will increase the speed by almost twice the intended input. From what I was reading it will result in a faster charge of course but the battery will drain faster if charged at higher amperage. Something like that, but I can't really recall.

Some YB offers 2 ports - 1A and 2A but not the magic cubes.

I own a 4400mAh magic cube. Love it except the smudges on the glossy surface!
For iPhone, 1A is enough. But my sister found it hard to get S3 charged with 1A.

Mine from mirrorstore.
It's genuine, directly from China. And much cheaper.

I saw another thread selling the same thing at much cheaper price; you can try searching in the forum.

RM130 can get 13,000 mAh luu bro.

@mirrorstore. She sells Yoobao directly from China YB factory/store. You can consider. I got mine from here.

But if you want the mobiledotcom sticker then :/

I verified mine as original from the YB webby.

Mine is a Pineng PN-929 15,000 mAh unit (RM 90). Serves the purpose well, with the % battery left that keeps me updated on whether to charge the power bank. Used <20% to charge my iPhone 5 full.

For mobility I use Yoobao Magic Cube 4,400 mAh. Been having it for a year plus and still serving me well at work.
