this is the most basic powerbank. 5v2a
other brand also rm25 only.

not suprised.

Just a heads-up, on a slight tangent:

Xiaomi recently issued a recall of powerbanks here, potential fire hazard.

how you know material cost already far exceeding??
10000mah battery,

cost to malaysia can be as low as RM15. ( supplier import cost + OEM white label )

RM20 for much better quality 1

10kmah is standard. can always open up and test the capacity (3.7v)

china is selling this at crazy quantity, eg those rental powerbank

the catch is fire

it will catch fire

china sell at rmb20 or RM18
now clearing stock because dont have CCC cert

even pineng brand is cheap what. you may got decent product with rm20.

though there is still chance of explosion even with known brand. use at your own risk

5000mah powerbank with no fast charging.
So yes the pricing actually is correct for that product.

if you think is junk what for you buy ?? rememeber this , cheap things no good , good things no cheap

Its goes to show that the efficiency of that powerbank is bad if it drops by half the capacity of the battery after conversion.

So yeah padan dengan harga.

usually cheap powerbanks are quite straightforward to identify

1. they dont have good certifications
2. the battery capacity doesnt live up to its numbers, good powerbanks have close to 80% efficiency rating (8k mah/10k mah). the pic says 5k despite 10k mah capacity
3. the charging ports are basic low powered 5W-10W charging (no PD support)

If its ok for you then no problem. :

The thing about cheaper powerbanks are that they dont last very long. Maybe the cells they use are lower grade, and often times, no where near the rated and advertised capacity.

I've had 5 pineng ones that failed after a year or 2 (some become pregnant), while my 3 xiaomi ones are ALL still working after 3-5 years. Those 20k mah 45W ones weren't cheap when they were new in the market (160) but I've just ordered another one for 70 recently.
Given decent xiaomi ones arn't that much more expensive than chap ayam, no point in saving money there.
I find for powerbanks, just as long as you charge them up before you fully drain them, they tend to last longer. If you have completely drained them, sometimes they dont charge up properly anymore or worst, fireworks when charging.

buy low, sell high
