Hi,

Nice info for the powerbank..

Recently I bought Pineng  PN-903, I'm using the 2.1A output port to change my Galaxy S4 and Note 2..however, the output is not up to expectation..just wondering is that normal?

Pls take a look at the photo..

[attachmentid=4005604]

It's only 1200mA using the 2.1A port.. 

Ok..I get what u mean..

Today I tested with my LG G Pro 2..even i off screen and turn on..its not up to 1400mA and its only 1000mA..while if I use LG original charger, I can get 1400-1500mA and charger rated 1.8A output..

Let's dont check it using app, with LG charger, I see 1 hour I can charge 50-60% of battery, but using this Pineng Powerbank I only can charge 36% for 1 hour.. 

I tried using XiaoMi Powerbank, it did well with my phone and output same with my original LG charger..guess this Pineng powerbank is not so efficient.. 

I will share the latest test result for Pineng 11200mAh again, to see the different after 1 year + of usage.

Slow charging ?
Do you mean the time required to charge the powerbank ? 11200mAh is really big capacity. 1A charger required more than 12 hours while 2A charger required more than 6 hours charging time.

Do you mean the time required to charge the phone? Because if you are using data cable, the charging rate will be slower. That is USB charging. If you are using charging cable to charge the phone (data pin shorted), it will provide AC charging, which is fast.

1. Slowly prise off the white plastic fascia on both ends. A small, sharp knife will do best with the least amount of chipping to the aluminium and plastic itself. Just be careful of the retention clips, but they are not clipped. Some small force will release them.

The cells read LGDBB41865.

Googling gives only LGABB41865.

I don't know if the 3rd letter indicates the cell quality.

It might not be a fake.....just another OEM brand using low grade OEM battery.

Zenfone 5 batt is only 2110 mah, to charge only 50% of 2110mah battery and run out of juice, there is really no difference between fake pb and low quality pb.

where can find such battery? and what battery brand u recommend?

You gonna get xiaomi pb, so just dump the oem one and use xiaomi, no need headache.

The mobile phone shop owner could not remember the name except that it starts with "S ". I was informed that even the Japanese made quality power banks cannot compare with this German made power bank. However because of the superior quality & build of this power bank, it costs < RM400.00. The shop owner's customer bought it in Germany. I am sorry I cannot furnish more detail of name of power bank. I am hoping one the forumers might come across this power bank. I am looking to buy it notwithstanding the price. Oh yes, the battery is of Lithium Polymer type.

Psychology?

China = no good.
White dudes = good.

Hi forumer.. wanted to ask.. my XiaoMi 10k power bank need to charge more than 15hrs only will full.. this is abnormal rite?

Wanna ask Xiomi sifu, mi 10400mah powerbank when the 4th led stop blinking is consider fully charge already right ?

Ok understood. My manual is in Chinese i can't read chinese.

I thought the device itself (phone/tablet) have capped the current input?

And I agreed that direct from power plug gives a higher ampere charging. One thing I do not know... 2.1A output do not even gives near the mentioned output. Or is it the phone charging being restricted ?

PS> It's sad Malaysia doesn't have a policy that recover and recycle batteries (all batteries are toxic if it leaks). Malaysians just throw it in the bin, that is so so so bad

The Xiaomi 20k should be the one with Qualcomm QuickCharge. It is worth getting.

Any model of Aukey have the QC output?
