Wait. What is this? Is it an Arctic Air Ultra? An Arctic Air Pure Chill? One of those expensive Blaux or Blast Auxiliarys that looks just like an Arctic Air Ultra, but costs almost twice as much? Well, it's kinda all of the above. There are a lot of solid features on this one. And surprise! A filter that looks a lot like the Arctic Air Ultra's, but a little different. However...all we want to know is...Does it Cool? Watch to find out!

I test 8 IKEA LADDA's 2450 mAh AA batteries through a range of charge and discharge profiles to determine if they live up the their capacity claims, and discuss results. Enjoy!

In this video, I test two different thermal modifications as well as the stock setup.
I did this testing after I discovered that my M1-based MacBook Air stopped charging due to excessive battery temperature after making the modifications that I saw on a few different YouTube videos and using it under moderate to heavy CPU and GPU loading.
The video details some interesting discoveries that I made, including the fact that many of the videos out there using thermal cameras (although well-intentioned) are not properly configured, and give erroneous measurements. Watch to discover more!
The tested configurations:
1. The configuration that I found in a few different already existing YouTube videos.
2. The second is the stock configuration.
3. The configuration that I came up with that I thought would work best.

I've been donating compute time periodically over the last several years to various research projects, but recently wanted to donate more consistently. I need my use my computer but want to continue to donate, so I was curious what computing resource might be an efficient, inexpensive and reliable option. Enter the Raspberry Pi 4B w/ 4GB of RAM.
If you are interested in getting involved, there are links to the current project that I am donating the most time, Rosetta@Home. The website provides information on how the project works, and how to get setup. In subsequent videos, I will walk through getting the operating system, BOINC, and Rosetta@Home configured. I will also walk through different tips and tricks to maximize the performance of the Raspberry Pi 4!
Enjoy!

Note: The RAC (recent average credit) scoring system is not absolutely accurate, but I used it comparing computers running similar tasks over the same period of time, running the same (or equivalent) versions of Rosetta and BOINC. So I feel it provided a solid enough snapshot of performance which can then be compared to the power utilized by each device. Cheers! :)

It's done! The comparison between the new Anker PowerCore+ 26800 and the 18-month old one. The results are quite interesting!
Next up, the teardown of the older pack!

It's time for some more battery testing! This video features the capacity and internal resistance testing of the Tenergy Premium Pro 2800 mAh AA purchased in November 2021.
Note: The internal impedance testing is still in beta, and there will likely be some changes in how testing is performed. When that happens, I will post a new video with the revised and/or extended testing and link it to this video. For now, please use this internal impedance testing as a reference point between the batteries.

Here it is! Finally! After purchasing two of the Anker Solix F1200 (originally called the Anker PowerHouse 757) and using them for just under two years, I discuss the quirks and issues that I've discovered with this model of power station using solar charging. I mentioned it in the video, and I will say it here again, it may very well be possible that Anker has resolved these issues with iterative improvements on current units being shipped. However, this is my experience with this product.
Both batteries were purchased with my own money.
This video was made by a real human, recorded on a real camera, and edited by a real human using video editing software.

Recently it was pointed out by a viewer that I didn’t clearly show how I took apart the Anker PowerCore+ 26800 PD in the previous videos I’ve made on it. I thought this was crazy largely because, well, I’ve made a lot of videos on that battery. I like it a lot, so yeah. Anyway, here is a video detailing how I open this battery pack. Note: this can probably apply to the Anker PowerCore+ 26800 PD 45W, Anker PowerCore+ 3-port Quick Charge 3.0, as well as any other Anker model that uses this extruded aluminum shape.
Thanks to Andrew Garl and Isabelle for pointing this out! I hope you get your Anker Powercore+ fixed!
