Probably a used goods, but for a brand new goods? That is outrageous.

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

sales count is too much to be used goods. anyway its a low cost product what. sure cut corner some stuff.

The label is 3.7v at 10k, and 5v at 5100. Translate to 10k powerbank just like any other marketing for other branded one.

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.

Need it so i buy it, branded one is far too unattainable. Unbranded one and cheap one is too suspicious, to a point safety might be questionable.

It is pretty standard for most powerbank to convert just half of the rated capacity, even the branded one, nothing look sketchy here.

then buy another phone that had reverse charge functionality or just swap to the spare phone then when there is battery low for ur main phone

If its ok for you then no problem. :

Use this powerbank is like waiting for death sentence. Anytime explode or start fire at home.

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)

Not so linear, battery is 3.7v, yet the usb port is 5.3v. Which is close to 70% disparity. Your best bet is get near 70% conversion given zero energy loss in the process. Some energy still get loss from battery to the cable and also to your phone, either way we just ignore some marginal loss that is unavoidable.

May be yours is li-polymer not li-ion cells.

yeah average powerbanks are 60-70% efficient (the rest are lost as heat), atas models claim 80%

cheap ones.. 50% also barely there

Unboxed, everything look fine so far, nothing broken or damaged…

meletup taktau eh

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.

can anyone suggest me good quality powerbank under rm 100?

Pineng has bad reputation of having low grade product, never get their stuff in the right direction once. All other brand too have their own unique flaws and perks. But overall didn’t get close to completely unusable hot mess products.
