Keyword 'ESTIMATE'

They just estimate the delivery date la.. Incase of any delay..

But normally they deliver before that.

Mine they attempted delivery at 8.23PM! Address clearly stated office maaa

Then just called, changed re-delivery attempt for tomorrow instead of scheduled 21/7/2014


Dunno what's wrong with FedEx now, my delivery with UPS all very prompt nowadays

Full 5200mah power bank, can only charge up to 15% for my ipad 4. Not impressive at all.

iPad4 battery capacity is 11,560. 5200mah pb should be able to charge abt 40%. Also ipad4 original charger charge at 2.1amp while 5200pb charge at 1amp.

Is it possible you left your ipad4 on with background activity? If there is any activity running, with 1amp charging, it might consume a large amount of battery that comes in from the charger.

ipad 4 11560mah

did u fully charge the pb ?

Nvm... The more the merrier. So I have more chance to buy my Note 2 or 3 of them. Sis and aunt mau also

Get 2x 10k or 3x 10k I assure you that you can fully charge it.

when mi4 will come out?

My PB 5200Mah are fully charged, theoretically i would expect around 40% from my ipad 4 also, but to bad it doesn't happen that way. You guys can try it out and share whats the outcome.

eh anyone know when the mipad will arrive in m'sia?

got 16gb and 64gb edision.

No you can't expect that.

It's about the efficiency.

No powerbank in this world has 100% efficiency. Even the charging circuit on your iPad can't be 100% efficient. There must be power loss here and there. Besides that, you have to factor in that the USB output is at 5V voltage while battery is normally at 3.7V and max out at 4.2V.

I came across a formula before, the actually capacity you can actually get on your device is just around 70% of the max capacity. Can be less. You really can't expect 5200mAh powerbank to give you 5200mAh out of 11600mAh battery in the iPad 4. Besides that, is your iPad powered on? I believe yes. That is another factor too.

Powerbank is not an unlimited source of electricity unlike the power socket in your house.

Wow... Seriously? That will be interesting!

Are charging while using are what?
iPad 4 have 11560mAh of battery, and Xiaomi PB 5200mAh, so if theoretical works, from 0%-40% should use 4624mAh.

i think the site is trolling people...

as you can see, they also prepare Mi3s and Mi4 for upcoming launch. doesn't make sense

OK lets say 5200mAH, with 70% efficiency = 3640mAH. Then with Ipad power on, it reduce again 80% from 3640mAH = 2548mAH. So the max capacity for an Ipad to be charge up, are only up to around 22%. But still im getting less than that. Correct me if im wrong.

Next time, switch off ipad and then charge it using a recently charged full 5.2K pb, then see how it goes. No point guessing esp when we don't know what is running with ipad on.

That's why Ive been asking what sort of percentage you guys manage to charge up.

I won't be bother charging ipad 4 with 5.2k pm anyway as I know its charging amp is only 1, way too slow.

Precisely why I bought (on the way) 10k pb with its 2amp charging rate along with its closer ipad full capacity.

5.2k is onlu 1A? I thought is same as 10k?

1.5A precisely.
