Myr20 for a piece.

What can be the low cost elements in this made to dump on landfill junk? May be can explode.

even sold at RM99

MR.DIY has a very very strict policy.
CHEAP is top and only priority.


they dont even sell energizer/duracell/enerloop/panasonic at most of their store.

you wont found bosch
you wont found nippon paint
you wont found logitech
you wont found tupperware

f... in instant noodle section.....
you cant find most premium instant noodle brand too.

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

not suprised.

I mean, the material cost to this already far exceeding the actual goods, they are mispricing by a whole lot, something is not matching in this thing. It is also can be found on any store btw.

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

It is highly suspicious to whether they are legitimate. Probably dishonest in the states capacity.

Just a heads-up, on a slight tangent:

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

It is legitimate powerbank. With genuine quality i believe.

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 basic way should be compare the rated capacity to the price. Like compare the price of memory i believe. 1gb for a dollar etc. 1000mah for a dollar etc.

the catch is fire

it will catch fire

Do you think it can go even much lower price? To a point even cheaper than electricity bill in the household.

Batteries can come form many manufacturers. Small companies may have lower operating cost but their smaller volume material purchase cannot compete with bigger companies perhaps. They may use lower cost material for casing and cheaper electronic component from clone chip manufacturers.

Explode or not depends can happened even on branded one also. Maybe can refer if the battery has CCP safety approval at least

Anyway, batteries are mostly (if not all) sourced from China. China has all material resources required and cheaper than any country I believe.

When it catch fire, can be use as fuel to boil water.

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

With a cert to higher the price by a one half, it is still very impressive feat.

3C cert 10000mah = RMB10

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

mr diy ada jual energizer.

There is fake powerbank that is made to deceive people such as 5000 capacity battery cell which turn out to be 800 mah at best, but at very low price. But I can’t tell whether there is a catch in this one.
