cheap tablet definitely using cheap quality battery, you can see in those powerbank.
So you want to replace the battery by yourself ?

do you know how much can i spend for better battery that can run for longer hour?
btw the tab is 7in..hmm..i will figure out later to replace the battery by myself or no.

i not sure about that, but how are you going to buy the right dimension of battery that fit into your tablet ?

yeah its not simple..maybe getting powerbank charger is the better option i guess.

ya. if it is 18650 or other standard size then it is easy to replace.
Powerbank is a better choice, but it is less convenient to bring.

Have you all seen this before?
It's a power bank tube that allows you to swap the 18650 batteries. Anyone bringing this into Malaysia?

What do you guys think?

there are lots of sellers on lelong selling 18650 4000mah at around RM15each, i doubt those are any good. anyone got recommendation for reliable batteries?

yea. i will try on my own first.
some allow mix with different battery, but some just parallel those battery and then conversion to 5V.
those with parallel type should use the same type of battery and with nearest internal resistance.

those 4000mAh are over rated. the maximum capacity right now is 3400mAh manufactured by panasonic.
so those with unknown brand and claim their battery capacity more than 3000mAh, mostly are fake.

recommended brand for battery: panasonic, sanyo, or samsung.

any reliable recommended shop/seller?

erm. since i haven't bought before from local shop, so i can't recommend any seller here.
may be other lyn members can help you about this.

The youtube one is just one piece of 18650 battery that can be swapped. Looks so simple.
If you try and it's good, please PM me ya. Interested to get.
Thanks!

using 1 piece battery, why not consider buying 1 more extra battery for phone ?

Because... using iPhone and iPad

And I want something super portable. Small and light.. can just throw in the bag. Thinking of getting Powerocks Magicstick now. Looks good. American brand. Any thoughts?

good reason. haha
i think at least 2 cell enough for use. iphone still ok, but ipad has very high capacity.
American brand should be expensive right?
But i will try for 2 changeable cell powerbank first.

I have 2 Yoobaos. 1 is the 11200 and one is the 13000. I opened up the 13000 model and it looks legit. My friend bought it in China for me at RMB280 at an upmarket shopping center.



I can charge my Note 2 about a little less than 2.5 times.

Looks like it is giving an effective rating of :

(3.7/5) x (13000) x (75%) = 7215mAh

Would this calculation be a good indication of real mAh rating?

x-treme, when u opened ur PN-910, u figured out that the 18650 battery is 2800mah based on calculation, did u visually confirm that its written 2800mah?

gud test

calculation can't indicate the actual capacity.
(3.7/5) x (13000) x (75%) = 7215mAh

7215mAh/ 3100 = 2.3 times

75% efficiency i think is because of large current drawn which reduce the efficiency.

RMB280 is quite expensive compared to Pineng.
