Lahat ng powerbanks use either Li-on or Li-po which both have around 3.47 volts. So sa step-up palang ng votlage to 5v, meron nang nawawalang juice kaya di mo talaga masabi kung anong accurate na numero. Kahit nga sa pagdaloy sa cable, may nawawala din. After ng ilang tests, ang pinaka the best na estimate ko pagdating sa para talaga ng mAh ng powerbank is kunin mo lang yung 64% ng advertised rating nya. Kadalasan tama naman yung mga ratings ng mga yan as long as sa mga reputable stores ka bibili. So kung may 10,000 mAh na powerbank ka, more than likely na ang kaya lang talaga nya (dahil nga sa nawawalang kuryente sa pag convert to 3.47 to 5v) ay around 6,400mAh. Kung ichacharge mo yung 2000mAh na phone mo, may makukuha ka lang 3 charges out of it. Tapos wala pa dyan yung nawawalang kuryente sa pagconvert from 5v back to 3.47v na nangyayari sa mismong device na chi-na-charge. Which is why mahirap i-quantify ang actual capacity ng mga powerbanks. From cable, board na nasa loob ng powerbank, board na gamit ng device mo, to cable, at kung anu-ano pang variables (kahit nga ambient temperature) dumadagdag sa loss of power.

Suggestion lang. Review/compare daily power banks na different brands. Under the same capacity. Sa ngayon kasi mejo false claim na. Meron nang true rated at hindi. Means 10k mah can have a 2 full cycles of 4.5k mah CP from 0-1% -99%. Or 20k mah that can charge 4-4.5 cycles of 4k mah CP. Kasi may binili akong 10k mah from official store. Then i used 4.5k mah from 1%-99% it used 60+% of the power bank's charge. When i complained to the seller. They replaced it with a new one. Pero sa description ng item they changed it to 5k-10k mah thats was originally 10k mah only. Im very sure this will help the buyers to decide.

Top 15 Budget Phone pls!! 💕💕
