- Yeah!!! It's another teardown! I forgot that I had this one left! It's the final chapter for the Anker PowerCore+ 26800 PD! It's a complete teardown, with some quite interesting components discovered along the way. Also, it comes complete with my low-impedance (*cough* sweaty) palm marks, as I was a bit nervous about taking this one apart. But I did it and it still works! I hope you enjoy! Here are links to the major components discovered and discussed in the video:
1. Batteries: LG Chem 3350 mAh cells (Note: this is the LGAB version, as I could not find the part number used in this pack. They seem similar though):

Do you know what's a good replacement USB-C port? I've got the same one but the port is faulty and I want to replace it.
I have a few surface mount USB-C connectors, but haven't checked to see if the footprints match. A few others are asking too, so I will look into this further, and have a video on it soon. Thanks for watching!
@@TheCuriousEngineerChannel Any luck finding a good replacement USB C port?
@@TheCuriousEngineerChannel Any good Type C replacement part?
I know its been a year lol. Mine was faulty.
I used electronic contact cleaner and a toothbrush. And flush it really good.
Wait for a few minutes for it to dry and presto it worked again.
now a 32bit Microcontroller? thats something i didn't expect! I mean you could run windows 98 with that kinda power hahaha seriously though impressive stuff you can tell Anker builds these things to last!
Them plastic tools reminds me of a set I had for taking apart Blackberry cell phones. Why take them apart you say.? To change to third party color cases.
3.39 is relatively empty. The discharge curve isn’t linear. For a 4.2V to 2.5V cell 3.39V is under 20%. That’s right at the point where the curve really starts to dive during a constant current discharge.
Hey buddy, I know this is an old video, but just to let you know, there is a version of this powerbank that has a Micro USB port input only instead of the USB C PD and 3 USB ports, one of which is a QC3.0 enabled port. That's why you see the "traces" of a third USB port there...
INR stands for lithium nickel rechargeable
IMR stands for lithium manganese rechargeable
GREAT video dude!
I just received the Anker PC+ and so far, I'm pretty impressed.
BTW, "INR" - That's battery chemistry classification for Lithium manganese nickel.
[I work in the vaping industry and am also into the RC hobby, so use bats like these all the time]
LG is definitely one of the best to use for high input/output charging/discharging. Good stuff! 👍
The LED ring... We know that we can push it once quick, and that each led-dot tells us 10% intervals..
Those are White leds. I pushed and held the button, and I also tapped it multiple times:
Both times, one of the white LEDs will switch to a single Green led.
All these people that do "review videos", and zero mention of this.. So, for inquiring minds:
Doing that will activate "Trickle Charge Mode" - Which is required to charge lower power consuming devices
[Ex: wireless earbuds, wireless bluebooth / wifi units, etc]
**This is a GREAT feature! I have other power banks [even 1 costing much more that can't do that]
Killer product Anker!

Thanks for the information. The trickle charge mode is very cool, but is only on the newer 45 watt capable PowerCore+ 26800 w/ USB-C PD. The previous generation that is rated 30 watts, does not have this feature unfortunately. Just be sure, I tried it - and no dice. :(
If you haven't checked it out already, I'd encourage you (and everyone :p) to take a look at Parts 1, 2, and 3 of the review of this battery. Thanks for watching!
@@TheCuriousEngineerChannel You're welcome, agreed, and thanks for clearing up the difference between the two different versions.
Bummer that the previous model didn't have that feature, but, definitely cool that the 45 watt PowerCore+ 26800 w/ USB-C PD does.
[Yup, that's the version that I have, and they work great]
Hey, thanks for the heads up about your other video parts - I'll be sure to check those out too!
👍

That SC8802 is a very good IC. Feb 22 Store uses that or a similar IC on their 120W bidirectional fast charge protocol module. It’s a 4S 3.7V only module but it has just about every fast charging protocol you could imagine. PD 3.0 plus the non standard 20V 6A PDO, PPS up to 21V 5A, QC 3.0 up to 20V, AFC, Huawei, blah blah blah.
Besides the IP2368 (very similar 100W bidirectional module) it’s one of the best Powerbank boards available on Aliexpress.
Amazing video!
I have noticed that this device doesn’t do pass through charging, so the single buck/boost converter makes perfect sense.
The ZMI power brick is also an amazing piece that is smaller at 20Ah, but supports many more protocols. I can charge it at 18W with a simple Samsung fast charger. The only downside is the heat when charging my laptop.
Man, you remember me opening clocks when I was a kid. The difference is that I could not get back to put the things in their right place.
I live in Argentina and we do not have technical service for any anker product bought in other countries. My usb c port I guess for a hit broke up and I am hoping this port could be replaced by any part sell in the market (for example, the guy who repairs smartphones. Do you know if the usb c port could be easy changed or replaced? Hope it could... Thanks for your video, it help me to open it up,
Possible to replace as long as only the physical port was damaged. If there’s any damage to the PCB then it’s garbage.
Soldering on a new USB C port is kinda tough for someone with little soldering experience.
Done a good job
After 2 years, how has the powerbank held up? Do you still use it now?
Oh. That PowerCore+ is now 4.5 years old, and yes I still use it often. I haven’t tested the capacity of it recently. Perhaps in a future video.
@@TheCuriousEngineerChannel its good to know you are still using it and the lg's held up with the rest of the electronics, cheers for letting us know 👍👊
I loved the video and appreciate the time you took to break it all down to us laymen.
I wonder why this batter is so much more expensive then the anker 20100 power bank witch I believe is around $35-$40 and only a few thousand mAh less. Thats bizarre but this battery is nice.
I ended up purchasing the ravpower 26800 pd ( I meant to buy the anker...grrr didn't notice I'd clicked on the wrong one). I've been charging it with my anker 21w solar panel which seems to work well. I'm thinking of getting a second one but tossing and turning over whether to try the anker this time. Especially after you mentioned other batteries charge quicker.
Excellent teardown on one of the best and most popular power bank - the only question i have is, WHY doesn't someone make power banks with replaceable batteries? There is no reason why they can't do it - whoever is willing to make the first powerbank with replaceable batteries, they will make a ton of money!
The metal would make sense why it cost more but not that much more. I'd really like to get my hands on one of these
I have to replace usb c port do you know which I can use. How many port ?
Thanks for the vid;
Can you charge with usb type c ? I need this for Samsung ultra?
Yes.
Just received this to in the mailbox! Your video is SO amazing. Thank you!
Wow...battery Promate good.....
thanks for sharing learned a lot.
Do you know the exact model number for the pd c port so I can replace it ?
Not sure if you need a 24 pin C port or if a PD charging port can work with less. Count the number of pins on yours
It's not a total teardown.
Nicely done :)
Hello! Nice vid man! Just wondering...how can it be 2s? If so it would only be 3250*4 capacity...but it is the double...so o guess it is only 1s8p..am I doing calculation right?
Thanks! I had a long answer aiming to explain this, but realized this would be a great video topic! Till then, remember that the capacity in mAh is referring is only to current per hour at a given voltage (usually the single-cell voltage, of 3.7Vdc). This pack has two cells in series at 7.4 Vdc(nominal). So the current would look like it is "halved" but the voltage is doubled. So, for me, looking at overall power is what helps clarify it all: 7.4Vdc * (3.350 Ah * 4 parallel rows) = 99.16Wh
Hope this helps a little; look for an upcoming video to explain further. Cheers!
@@TheCuriousEngineerChannel mmm...ok...I'm no expert by far..just quadcopter pilot and industrial engineer :) for me cells in series is doubling voltage and parallel is doubling capacity... anyway I'm looking forward to seeing your explanation video. Have a good day! Ps subscribed ;)
@@travisPiru It comes down to marketing. Since it can run multiple output voltages they're rating the pack based on the 1s8p capacity with the 'functional capacity' depending on what you charge with it. Drones are rated by their Xs capacity rather than 1s capacity because you're running the system at a single output voltage due to efficiency and weight restrictions, with flight time being a huge measure. A battery pack really should be marketed based on the total Wh instead of marketing jargon mAh, particularly with the FAA restrictions applying to pack Wh.
@@KevinPetersonmoonismyhomebingo. This is the same reason why they round up to 3.7V when most 18650’s are 3.60-3.65…typically 3.625V is what you’ll see on the datasheet. Marketing department figures…well round up to 3.7 then the wh looks bigger and people will buy ours because it’s 5wh more than the competitors
That 3rd usb A port was originally installed on the first iteration of the Powercore+ 26800
It had 3 Anker IQ Ports, one of them was Qualcomm quickcharge 3 able.
And it had a micro USB port to charge.
They changed the 3rd outlet to the usb C port which is out and inlet, and canceled the third USB port...
Hi pls come and see Odec power bank, let me know if you are interested hah~
...know when I need to know!
Anker has thermal protection on board. Batteries don't need it. discharging these bad 2S4P 3400mah li-on 10a output batteries cant generate any heat. But charging with 45W / 8.4w = 6A max, which means 2A per cell is nominal charging capacity of them, 0.5c, it does not generate any heat over 40c.
Hello dude know which cells are these?

Great teardown, I learned a lot! One thing I'd like to do is to modify the PCB such that it will always be on, even when there is a very low power draw (e.g. arduino project). I'd like to avoid increasing the power draw on my project, because I'd like the powerbank to power the system for as long as possible. Any ideas on whether this is possible?
It's possible, but I wouldn't recommend modifying the PCB on the PowerCore+. For short-term, perhaps just plug another low-power load ~100mA@5Vdc to keep the battery running. I'm feeling I might make a video on this to explain in more detail. Thanks for watching!
@@TheCuriousEngineerChannel It would be interesting to see if it can be tricked into staying on by asking for 100mA@5Vdc for a millisecond every 5 minutes or so. This way it wouldn't increase the power draw too much.
