thank you so much for this channel and this content i have been looking for someone that can show us what we are buying and the quality of the electronics that we buy. your videos were very useful to me so please continue with this fantastic work.
Glad to help
Thank you so much man, you have no idea how helpful this is. It would be great if you could give a rating at the and of the video (1-5 or so) for quality.
How can u remove the cover. I cant do it
Another great video. Thank you
How can u remove button and screen cover
How to identify i the battery pack is Li-on or Li-po?
Is it matter on differentiation in term of long term usage?
Love your teardown videos! Can you do the teardown of Nitecore NB20000 anytime soon? It is very lightweight and used by a lot of hikers, runners. Thanks!
Great video my guy,
Now I can rest assured that mine isn't gonna blow up when I sleep with this power bank next to my pillow charging my phones
🤣
Is this compatible with charger of realme 65w?
If this is a 20ah battery pack, shouldn't they be in parallel and not in series?
I've bought it and only seen negative reviews so now I'm second guessing this
After removing the bottom cover, what is the process of pulling out the whole pack? It seems it’s not coming out for me 🙄
I've done this with my adaman 10000mAh by removing side button (almost destoy it) and removing plastick glass of LCD.
Yeah, it's missing a good explanation for a _full_ teardown and not skipping critical steps like that ...
I destroyed mine trying to open it because those steps were not explained. No clue how you're supposed to remove the button and LCD without damaging them. Me the button is in pieces ...
can u do the 20000mAh 20w?
Bought it yesterday, tried out today and will bring for a repair/refund tomorrow.
From a full charge (100% on screen and no energy consumption over the wire) it gave 5400mAh until it reached 40% and then it died like it would be at 0% - no reaction to a button, no charge given. As soon as i hook it up to a charger it boots (showing 0%) and in 3seconds show 40already. Given a few seconds charge from that shown 40 and tried to use it to charge phone or anything again - bam it goes flat again at 40%
When charging the powerbank itself with quick charger (60w), it grows from 40 to 80 smoothly and then at around 82 it just immediately jumps to 100 and stops charging. Hooking up 5v charger instead of a quick one still allows to push in a few percent.
Saw those negative youtube videos before buying it but thought (its just one of thousands and it will not happen to me.. boy i was wrong).
Do not recommend it at all.
Happened to me..this product so many defect
To me and two other friends, too
Happened to me too. I emailed them and they sent me a brand new one so I still had the broken one. I bypassed the battery protection board and it seems to be working fine now. 2 for the price of one!
Same, but mine was showing 22% and died. When I plugged in charging it showed 0% and then after 3-5sec it changed to 22%.
Same, any way to fix it? Maybe broken resistor, etc
Very good review
why my PB cant out 65 watt? 😢
Is it dangerous to bypass the battery protection board? Mine was delivered broken. I diagnosed the issue to be somewhere in the battery protection board. I bypassed it and it seems to be working fine. Just concerned if bypassing this board poses a fire hazard?
Hey are you good at fault finding such stuff? My 65w baseus just died, usb 3.0 completely dead, usb 2.0 showing its charging up the power bank rly fast like 2 percent per second, then it gets to 99 and stays there, is it worthy to try to solve this issue or just buy another? not baseus ofc xD
My "fix" didn't work long. Eventually it stopped charging again and out of caution I threw it away :/
Mine stop working only mini usb can use it blink from 1 to 3 until 99 when try to charge it all other port dead , very weird problem
@Cikgu Aman
hey, I found out what the problem was in my case:
There is a chip that is responsible for the 20v switching from the battery and the usb c port, also it powers the other circuits as well I think, the chip is called "southchip sc8721", it shorted the input and the output of itself
The battery was save and not completly drained do to the seperate bms board, which cut the power
I found with ir camera that the input power shunt is getting hot and the coil right next to it on the other side on the board, the soutchip was also in line with these 2 and had less resistance, therefore I couldnt see it right away, but thats was the short reason for sure, because after I soldered it out with hotair the short was gone
the board accepted power from the lab power supply and was showing a charge state that was reasonable, but as soon as I use the usb a, it blinks two times and turns off
I think replacing the chip will fix everything, but I didnt get a new one so far, for me in germany it looks like the only source for these is alibaba and I have to take 10 of them, which is fine tho, because they are only 1usd each
in case you have no option to solder this, you might be able to buy a usb c to battery charging board, search for "120w Two-Way Pd Fast Charging Module 4 Strings Charging Treasure Module Circuit Board High Power Pd Fast Charging Boost/Buck" on aliexpress, these should run with 4 cells in series
and then you replace this, but maybe check if the cutoff voltage from the original bms is set proberly
So is mine
Thank you. Wonderfull video, great channel very useful. It help me to purchase this model. 😊
Glad it was helpful!
are you satisfied with it? charge time of the powerbank itself? Thanks!
Hi, what do you think what is better Baseus 65W or Xiaomi mi 50 W powerbank? both 20 000mAH
Same question here
break off the front panel. I wonder how you will collect it.
@ChargerLAB Please Make a Video on Basues Adaman 20000 mah 22.5 watt powerbank
Hey ChargerLab , Does the type C port of this Baseus 65W power bank supports Samsung Superfast Charging both 25W and 45W?
Yes
Faz o teste com Power Bank Romoss
wich the best this model or the model with orange cable
It depends on how you use it. The 65W with an orange cable is more convenient for traveling.
And this 65W power bank is more suitable for indoor use.
@@ChargerLAB good thanks
the failure rate of this thing is a bit unlucky, we bought all in all 6 of these for familiy and friends and one of them had right after using it one time a short in one of the usb A circuits another one got a usb A with a not working contact, so only 2 ports out on that one and a 3rd one now failed completely, the last thing it did was to pretend to charge from 0-100% in 2 mins while drawing near to 0 power, so the battery itself is probably good but the circuit is not that good in my experience
same here, don't show anything when i try to charge it by the usb c port, but when i plug in a micro usb cable (with 45w samsung charger) it charges from zero to 100 like 2%/s

@@berberger4814 thank you very much, I may take it to a repair assistence, it is an great, well built and expensive powebank.
@@gabrielsouzaperes1084 Have the same issue. Tore it appart (and destroyed it, no way to put it back together) and found the issue : One of the 4 cell is just dead. 3 are fine, but one isn't taking charge and is reading 0.5V.
@@smunaut actually thats not the same issue, the bms of mine did prevent it from discarging further since the sc8721 was shorting the bms out
so my cells are all fine, still reading 15.83 V (just checked) - so they are good
for you Id bet it was water damage on the bms pcb or another random failure on the bms board - infact I think your pd controller board should be fine
#chargerLAB please i humbly request you to make it teardown the joyroom's 30k mhA powerbank of 22.5 watt, model - JR QP 193..
Wow verry indepth and comprehensive! Thankyou for making this video
Not really, it's a teardown video where they completely skipped the part where it is practically impossible to take it apart without breaking the button and display cover.
You just show remove back cover! How to remove top cover, power button and plastic cover information?
How do you loosen the the aluminum sleeve? Can't get mine out yet....
Just get a spudger and pry again and again.
@@ChargerLAB Stop lying! You know very well you have to remove the button and display cover which is pretty much impossible.
@@monkeystation mira no se si en español te valga la respuesta, pero con una navaja acabo de desmontar mi powerbank entera, hice palanca con la punta y también me sirvio para los tornillos, el botón empece a meter la navaja e hice palanca sacando poco a poco el boton, y la parte de la pantalla le di a una pestaña por dentro y después cuando conseguí hacer un hueco como para meter la navaja empecé a dar vueltas hasta que encontré la otra pestaña y tiré
nice
This is a good powerbank
It's not, mine just stopped working after 8 months with barely ever using it.
@@monkeystation My ravpower only died in 5 months battery was fried or it short circuited idk what the problem was but this shouldn't fail seems like you didnt read the manual
I am a student I buy basus adamim black 20000 22.5w power bank. But I cannot use it only 3 month it just broke now it did not work very bad basus 🥺 ,, my mi powerbank after 4 years still working fine just lost full capacity
Same here I had a black one and it broke after 3 months just went to the newer 65w and hopefully this one last longer
You can definitely report this to Baseus official to get a refund or replacement.
@@ChargerLAB i live in Bangladesh and there is no chance of repair officially and refund,, recently i buy ip5328p powerbank circut and fix the powerbank. ❤️
I got the same problem
@@ssjihad7014 this shouldnt work with this battery actually, because it has a voltage up to 16.8v (thats at least what the video says, and also my opend one has also 16v) and the ip5328p can only handle one cell and has a max voltage of 4.5v on the battery input according to the datasheet
my SD59D24B just died :(
I just bought this powerbank assuming i can charge my rog phone 6 with 65w power, but in reality it's not supported and only draw 18w 😂
😢😢😢 mine just dead after 4 months light used
What kinda teardown is this? You didn't even show us how to get it out the blue outer frame
These people are lying. They act like you can just slide it out after removing the bottom cover, but you can't. You can clearly see they had to remove the side button and the display cover. Also they broke off the plastic top cover. Shame to spread misinformation like this.
I just took one apart, and you do indeed need to remove the display cover. It pops straight out, but is a tight fit. It's hard to get out without marking it up. The power button does not need to be removed. You can push it in while sliding the cover down, and the cover will slide over the power button.
The jumpcut between 2:57 and 2:58 is brilliant! It took me almost an hour to go from popping the back cover to sliding the isides out. No, the power button does not slide with insides, it have to be removed first.
now its currently unavailable for India
Damn that was a complete waste of time you skipped almost the whole process how the hell did you get the power button out at least
heat the glue stick, press it against the button and when it cools, pull. The button is attached with three latches. sorry for bad english
The one I bought in September 22 isn't working May 23. Ive probably used it maybe 20 times in that period. its a real shame. Why cant any chinese stuff be good? the only good stuff they make they have to steal from actual talent.
This powerbank is garbage! I already got the secound one that stopped working after a few months.
At some point it just makes clicking noises and neither charges or discharges.
Don't buy this crap. Cheers!
