Nice! The very first powerbank I owned was a xiaomi 10400mah, bigay ng kapatid ko, looks like this:

Nabili ng kapatid ko sa Singapore, and hmmm, not a good brand, imho. Was only able to fully charge 1 1/2 times my LG Gpro.
Not sure about the price.
My second one, I bought few months back sa local online store dito sa Pinas, is ACE, nag sale sila when I bought it, @499Php
I must say it's a good brand, I actually bought another two, dahil nga naka-sale. The powerbank says it's a 20000mah, but per my calculations it's only around 15000 to 16000 mah. For a 499Php price tag, not bad at all. Reliable din yung lcd diplay nya which shows remaining power, plugged-in device etc.

The current brand I'm using is Pineng. And I must say, it's a "bang for the buck". Sayang lang kasi nabili ko siya ng 850 Php, tapos biglang nagsale ng 759Php, now it's currenlty sold @1kPhp. And it's a darn real 20kmah!

Yung xiaomi, ang tagal mafull charge, tapos yung nga, hindi man lang maka twice full charge ng LG G Pro
Yung ACE naman, 8-9 hours ang charging time (from 0-100%), using my tablet's power charger @ 2 amps max
Yung Pineng naman, since 20000mah xa, hindi ko pa matancha yung oras, bihira ko kasing maubos all the way til it gets to 0%.
Update ko nalang ulit
Habol ko lang, ang common sa tatlong model/brand na ito is, they all comprised of 18650 batteries, xiaomi was 4 (LOL! i keep on saying
was with xiaomi kasi, dhil inefficient xa, binaklas ko nalang at ginamit yung apat na 18650)
Ung Ace, binaklas ko rin ung isa kong nabili, the 18650 battery doesn't say anything about the capacity, as in wlang nakasulat, hindi naman re-wrapped, but I think it's about 1800 to 2000 mah. Eight lahat ung laman na 18650 si ACE.
Si Pineng hindi ko pa binabaklas, although I saw someone disassembled a different model of Pineng sa youtube, and same as I would think of it, each 18650 has 2500 mah capacity.
I'd really suggest everyone here to buy these types, I mean yung 18650 li-ion ung laman, yep mabigat BUT napaka tibay naman (nung battery). Unlike those Li-Po type (ito yung type ng battery na gamit natin sa mga tablets and smart phones), yes, significantly lighter nga, but kapag nag bloat na, patapon na.
Ung mga 18650 Li-Ion naman, masira man, like my xiaomi, may gamit parin ung batteries nya, and gamit ko parin sa hand fan namin at sa tactical flashlights ko.
And another thing about 18650s, if they suddenly die (meaning, it wont take a charge anymore kahit pa there's continuity while checking it with multimeter), there's a 90% possibility na gumana ulit, may need ka lang pisilin dun sa top portion ng battery.
