Hello everyone, in today's video I will

00:00:10

raise a topic such as the

00:00:12

combustion of power banks. Many of those guys

00:00:15

who bought cheap power banks

00:00:18

encountered the fact that they

00:00:20

usually failed, to be honest, they do not fail

00:00:23

on their own; they either fail due to overload

00:00:25

or, as a rule, it is either goats

00:00:28

or polarity reversal at the input of the board in

00:00:32

this case, this is this contact,

00:00:35

that is, when we have a

00:00:38

battery here, let’s say one joint is correct

00:00:40

2 is incorrect, this is kosis polarity reversal

00:00:43

often here is a symptom of the

00:00:48

profit of reversing the polarity of

00:00:51

special rodanium batteries, correct 2

00:00:53

incorrectly, the

00:00:54

plastic burns out in the place where we have it

00:00:59

it is the case between the batteries and here

00:01:02

the contact heats up almost to

00:01:04

white metal and, accordingly,

00:01:07

if you don’t hold it for a long time, then

00:01:10

your case is cheap plastic and will

00:01:12

instantly melt in this place

00:01:14

here a little bit, it’s just literally a

00:01:17

split second short-term switching on of

00:01:19

the battery against them and they took it out and that's what

00:01:22

happened, the metal instantly

00:01:24

heats up like a cigarette lighter and the whole

00:01:27

battery, by the way, may also not survive

00:01:30

after this, most likely the boards we have

00:01:33

here are different, even from the photo on the

00:01:37

topology of the board you can see that it is slightly

00:01:40

different and this is actually the

00:01:42

third board being installed, here they are with each other I

00:01:46

will continue to keep these two secret examples,

00:01:48

use 2 4 egg ones, they seem to be the same from the

00:01:53

same seller, but the board is

00:01:54

completely different, the symptoms are basically

00:01:58

the same, here the plastic wouldn’t melt, it

00:02:00

would also be a reversal

00:02:02

of the batteries, let’s see by the symptoms

00:02:04

what happens when we

00:02:06

connect the battery,

00:02:07

what do we have a powerbank for now

00:02:10

they call the indication no flashlight

00:02:16

in this case also does not light up well not

00:02:19

warm not cold nothing tester also 0

00:02:25

shows you like a completely dead

00:02:32

brick the role of the

00:02:40

flashlight works double click on the

00:02:43

flashlight it turns on everything is turned off

00:02:45

normally indication as you can see there is no

00:02:51

output accordingly also

00:02:54

emptiness and this is also so peculiar

00:03:05

now battery here we connect the

00:03:08

red ones at the combustion point here the indication

00:03:14

works and the flashlight works

00:03:19

new ones for us at the output we have zeros

00:03:22

or rather the voltage is not exactly zeros the

00:03:24

output voltage is equal to 3 6

00:03:26

equals the battery voltage, that

00:03:30

is, a breakdown to the microcircuit tickets inside and

00:03:32

at our output it’s just direct the voltage

00:03:34

is 4 36 volts and the board is 10 10 it turns out the

00:03:38

node doesn’t work at all so how can we

00:03:43

fix this problem let’s

00:03:47

first look at what we have on the board and

00:03:49

what can be done with it we stand here,

00:03:54

basically on latches, be afraid of

00:03:56

nothing here we have a microcircuit like you see the

00:04:00

nameless one, this is the kind of board who

00:04:05

will have the same chips absolutely nameless

00:04:10

clean bare no signatures there is nothing

00:04:14

on the board except a few resistors 1 is

00:04:19

very crookedly soldered in by the way but we will

00:04:22

now try to fix this and and

00:04:25

and all semiconductors there are no

00:04:28

Conder resistors by the way 00 type

00:04:32

fuse I swear to this and 1

00:04:34

inductance is this one that we can

00:04:37

check in principle right now

00:04:40

when we try to repair it,

00:04:42

so for the second one, get it and see 2

00:04:51

we have already signed and here we have 1

00:04:54

joke even with a 34 microcircuit, etc.

00:05:00

42 21b the microcircuit

00:05:04

is, in principle, universal, I also

00:05:06

shouted 42 23b,

00:05:08

but as I understand it, there are no special differences between them,

00:05:11

so you can change it in

00:05:15

this version now, carefully

00:05:23

remove the cans

00:05:27

like this 6 because our night lights are mp 3411

00:05:34

dps company so here dpt power here the

00:05:40

power here tps manufacturer is also not a

00:05:44

joke, there is absolutely nothing, and so what

00:05:48

we have is the

00:05:50

t-power dps 40 2021 microcircuit itself, this is a specialized

00:05:54

circle for power banks, primarily

00:05:56

for budget power banks of probably the

00:05:58

very first thing, it can, in principle,

00:06:02

only monitor for the level of

00:06:05

charge discharge, turn on the flashlight with this button, this is the

00:06:10

indication, display this same button on 4

00:06:13

LEDs like this, the button

00:06:17

itself and in principle, all its protection is at the

00:06:21

top 42

00:06:22

at the bottom three and two volts current at the

00:06:26

output it has protection only from 08

00:06:30

ampere will not work across the load

00:06:32

and to protect the connection of this 1 1

00:06:36

maximum legs on the first I will say about on

00:06:39

principle y gives so as you can see it

00:06:43

heats up normally if I’m not mistaken

00:06:45

extinguish y it is not indicated 150 degrees the

00:06:48

maximum temperature at which

00:06:49

the protection is triggered so I honestly do

00:06:52

n’t I know which case does not

00:06:54

melt at this temperature, but it seems to

00:06:56

work now, I

00:07:00

’ll try to change it carefully, I’ll change it to

00:07:04

these and good brothers of

00:07:05

the power, etc. 4221 to b is the same thing, in

00:07:12

general, I ordered the same blood circuit

00:07:13

in China, the link will be below

00:07:16

I ordered to buy come off on, so it

00:07:19

turns out the cheapest, well, let's

00:07:22

try the daughter series or they were

00:07:24

called to solder, what will we do,

00:08:17

so I soldered on our powerbank with

00:08:22

microcircuits, etc. P. 4221 and now we’ll try to

00:08:26

set it up, let’s check what it is, and how the

00:08:37

indication works, I can already see it’s working, let’s check that

00:08:40

we have 2 amps here, that’s us 4

00:08:48

volts 1 1 mode

00:08:49

4 and 7 volts, but practically 4 6 volts and

00:08:54

920 miles ampere gives

00:08:56

but in principle a decent result from the

00:08:59

usual result for this mikruhi

00:09:01

it may start to warm up a little, well, as I

00:09:03

said, it will hold up to 150 degrees,

00:09:07

in principle this is a normal temperature,

00:09:11

we get it fixed,

00:09:13

it will work for us and now let’s

00:09:16

return to the second type

00:09:18

of power banks and to the second type the

00:09:22

circle 40 eyes are watching the most popular

00:09:24

it comes in almost all copies of ciao

00:09:26

me your power bank of there are 4 cells and

00:09:31

almost all of them are built by us for

00:09:32

octal, well, not built, and well,

00:09:36

these ones are also plastic, for the most part,

00:09:38

but there is also a second type, as I already

00:09:40

said here, this is nameless,

00:09:43

nameless without Schottky diode and here this

00:09:47

nameless sign is signed

00:09:49

and thanks to this we can find out what

00:09:51

this company is called tps is called m p

00:09:54

3411

00:09:58

this is how the board with the topology does not look like

00:10:06

as you can see they are radically different

00:10:08

4221 is powerful

00:10:12

and this is less powerful without such polygons

00:10:16

although it is also essentially solid Polik, he’s

00:10:19

just here, so you can growl

00:10:22

and stick it in understanding, and I’ll tell you why 34 11

00:10:27

I’ll throw a link on the stage and throw it downwards, it

00:10:29

has a working temperature for protection

00:10:33

when the thermal protection is activated, 100

00:10:35

degrees versus 150, how to understand the difference is

00:10:38

huge, the

00:10:39

second point is that it has a lower threshold for

00:10:42

protection battery 29 volts

00:10:45

nominal minimum 28 maximum

00:10:48

voltage 3 volts at which

00:10:50

the protection will work at the lower threshold for

00:10:52

the battery at the upper threshold

00:10:54

maximum 422 minimum 418 this is

00:10:59

also a significant indicator current is also

00:11:01

about 1 ampere but one and a half amperes in

00:11:04

two ampere

00:11:05

in 2 ampere mode they will sell to us

00:11:07

mikruhi can serve has moved around

00:11:10

us is coming more progressive and new,

00:11:14

respectively, to find and sale is harder and

00:11:16

it costs more, although the cook

00:11:19

bought the cans for one price, it costs

00:11:22

a penny, but I found this for now only above

00:11:26

Albau for 1 dollar, even a little more than

00:11:28

one dollar for one such crumb,

00:11:32

therefore As you can see, there’s no point in buying it

00:11:34

at all, but nevertheless, for the sake of

00:11:39

general development, I’ll tell you what you can

00:11:43

look for here for a replacement, in case someone

00:11:45

needs this particular tps to, so just like

00:11:48

that, fix them like that, I won’t be the

00:11:51

most profitable

00:11:53

of them, micro USB pulleys,

00:11:56

you according to these spare parts, the boxes are put somewhere there, in

00:11:58

principle, here’s a scientific guide,

00:12:03

I explain to you what you can do with them,

00:12:07

so in this video I looked at what

00:12:09

can be done with a burnt out power bank,

00:12:11

what are the

00:12:12

main reasons for the breakdown, this is, as I already

00:12:15

said, the meters itself, the main controller is mikrukha

00:12:17

and also, well, the contacts, the outgoing

00:12:20

connectors are loose, that goes without saying,

00:12:22

whoever liked this video,

00:12:25

like and subscribe to the channel,

00:12:26

all the best bye
