Introduction
---------------------------------------------------------------
Several weeks ago, we posted a teardown video of the CUKTECH No.30 power bank. And today, we got another power bank from CUKTECH, the No.20 power bank.
It looks like the Anker 140W PD3.1 power bank we took apart before. Let's go ahead and take apart this power bank to see what it looks like inside.

Awesome power bank. Just bought one. Easly open, even better. Great teardown!
Wow so easy to open, they should sell replacement cell, and market this power bank as repairable
amazing beautifully constructed
I will never not laugh at CUKtech
indeed
Will smith approved
Can u tell me why? Dun understand 😅
You're a better man than I 😂
Yeap. XD
Finally the Cuhk tech power bank!! ❤❤ love this video! Support
More to come!
I wish some brands would have a powerbank battery replacement service.
but then you wouldnt have to buy a new one
I've had the Powerbank for a few weeks now. Hands down the best I've ever seen. One of the nice features is that it allows parallel operation of all ports and even charging from two power sources simultaneously, e.g. Solar panels. If I had one complaint: It is rather power hungry, just operating the MCU alone will consume around one Watt so if you keep it connected to a Solarpanel in the shade, it's actually draining the battery...
Hey, where did you order it from? Shows out of stock on Amazon currently. Any other source?
@@himshurai Indiegogo
@@danielegger6460 Ah, ok. The campaign seems to have ended there. Couldn't find it anywhere else.
So much nicer then ankers 737 power bank. Anker 737 has to be broken open unlike thr cuktech. Can you do a teardown on the cuktech no30.
They probably should've consulted a native English speaker before picking that name
what for, if their primary market is non-English? needs to sound good in China, and it does
For all ignorant and uneducated jokers, it actually is Tchuk. It is named afer a famous Serbian inventor. Tchuk means hammer in Bulgarian. Not does only thr power bank look like one...but in Bulgarian slang, calling a technology Tchuk is the ultimate recognition of high quality. So, the manufacturer really nailed the choice of name. With a hammer.
One of the main problems I know is in these devices is the batteries themselves usually after 500 charges those batteries become useless. everything else looks pretty good. What they use now to power these Chargers. They're not going to last in the long run. They're going to have to replace them with LiPO batteries that will last a lot longer than these batteries will. And it will make the device a lot lighter. That has to be addressed.
Luckily near my place there’s a bunch of dudes who loves doing DIY powerbanks they can easily swaps better battery cells in these bad boys after they gone kaput :)) but these devices are nice for what they offer. I just hope technology develop enough for 200w and above single port so lower powered gaming laptop can charge with ease. The heat would be immense lol.
LiFePO4 cells have lower energy density, so wouldn't it be a larger unit?
I like that power banks can be charged so quickly now.
The real answer is consumer replaceable standard battery cells (and recycling of old cells). Also best not to confuse LiPO and LFP / LiFePO4, they are completely different chemistries. LiPO (lithium-ion polymer batteries) do not typically have a longer lifespan; LFP/LiFePO4 batteries have much longer lifespans (thousands of cycles) but have significantly lower capacity.
@@theclifbar That is not the question I'm asking the question I am asking that the common man can understand, and i am not trying to be offensive but how long it would take to charge the power bank from minimum up to full capacity that the common man that does not know such things in regards to batteries can understand? That is the question.
If u used lifepo 4 the Powerbank must bigger than this and much heavy cause energy density is lower than lion...
ayo WHAT tech???
😂
Wich one is more energy efficient the and better build pbc the Anker 737 or this one ????
I bought it after watching your wonderful review. It's such a shame that such a well-built device has to be thrown away when the batteries end their useful life. The internal batteries are easy to find of the same brand and capacity, but replacing them requires desoldering the old ones and redoing the various connections.Not impossible, but not easy either. Shame on Cuktech.
Hi,have just received this power bank,i just noticed that on the display it showing discharge on the usb port when there is nothing connected to it?
Please teardown zendure c4, iam very curious about it
Baseus power station 4 87w charger+ powerbank
Is better then Anker powercore 737?
Can you teardown of Sharge Starship Seer power bank?
Cuktech is definitely cuckcolding other battery company 😂😂😂😂
CUKTECH = Xiaomi = ZMI
Good chargers and Powerbanks.
Is it possible to easily remove/replace the battery cells, or are they soldered in place?
It is easy if you have spot solder machine to replace new battery
@@uyluccanhsatmy3016 thank you for confirming! This is the best battery bank I've seen yet then! The fact that you can disassemble it without destroying it is amazing
JP316 test plz
Where Gan?
Chào bạn co thể làm về pin joway jp 316 được không vậy cảm ơn nhiều
Dem kaannt ma doch links und recht auf Licht klopfen oder?
I got this....NOT HAPPY..it acts odd with some cables to my S24U..got 2 goood anker ones..only one works right..got 2 cheap ones..they dont work good...the Amps..Volts...Watts..time..keep jumping up and down...so it doesnt charge fast..but if yoy get the right cable it is pretttty fast...so i might return it...
Anybody else have thos problem?
