Here is the back side of the powerbank. No "actual capacity" rating.

Hi, I've bought a powerbank (AlzaPower Parade) which is a 30000mAh 60W one (111Wh s rated on the case). First thing I did was charge it to 100%a nd then charge with it my phone from 60% to 95%, which has a 5000mAh battery, and the powerbank went down to 75%. With these numbers it comes to at max 2 phone charges, which doesn't seem right. Next I took a USB-C tester, and did two 0-to-100% charge and 100-to-0% discharge tests. When charging the powerbank it reaches 50W and trickles down to 10W and then 5W. When charging a laptop with it, it managed to put out 55W-58W. So the power rating is legit. However, charging the powerbank only took 65Wh and 74Wh. Discharging it totally until it shuts off, took once 61Wh and then 67Wh My laptop has a 46Wh battery, and while running (idle) it charged it from 4,6Wh to 33,5Wh, USB tester was reading 67Wh, based on idle power usage experience tester seems to work ok. Now I know that I wont get the full rated capacity, deliberately miscalculated by the BMS to keep the battery healthy, and watching reviews you get 85%-90% of rated cap. In this case, it was more like 55%-60% Is this normal? I just sent it back, they replaced it, and I'm reading the same low capacity from my tester. TL;DR: 111Wh powerbank only outputs 67W = 60% of rated capacity.

Hi, I need to buy a laptop for my family member who will start studying mechanical engineering next semester. Based on my prior experience with bussiness laptops, that's what I'm looking for in either 14" or 15,6" size (since it will be used with a monitor, size doesn't really matter), and used. For my budget I can find the following models: Thinkpad T560, T570, Dell Latitude 5470, 5480, 5580. The common spec is 8GB RAM, 250-500GB SSD, and the following CPUs: i5 6200U i5 6300U i5 7200U i5 7300U Is this enough for light use of AutoCAD and 3D modelling? (Either Inventor or Solidworks). I've finished my engineering studies with a laptop that had an i3-2348M and 8GB RAM, and it was ok for it's job.

Ok, problem solved which was the codec I was using. Installed Icaros and set it to use embedded cover art thumbnails if possible. After an explorer restart and thumbnail cache delete, TCMD and File Explorer started showing the embedded thumbnail

I use youtube-dlp to download Youtube videos. yt-dlp is also able to download and embed the original thumbnail in the video file. Sure enough, checking it with mp3tag a 1280x720 png image is in it. However browsing with Explorer or Total Commander, with large icon view, does not show the embedded thumbnail but auto generates one. Is it possible to force it to display the embedded one? Using latest Windows 10, also my default video player is PotPlayer, if it matters.

Just an example: Portainer allows me to access a container's console through the webUI. Is this a security issue too?

Except that it would be much faster and easier. Imagine going to a new computer: I would have to install OpenVPN, transfer there my ovpn profile, import it and connect. (Oh and if it's not my computer, remove my profile afterwards and possibly OpenVPN). Then I would have to remember the IPs and ports of all my services. Instead of this, all I would have to remember and open is mystartpage.com, where everything works through bookmarks.

Hi, I have a server running services in Docker containers (sonarr, torrent, rss, adguard, etc.). I really don't want to give them public URLs. So far I've been using them remotely via VPN, connecting to my home network. However I found Organizr and mistook it as a "portal" to my home network. I thought I could access Organizr remotely, and in it get access to my local services' webUIs (e.g. 192.168.1.105:9191, that kind of things). Unfortunately that's not the case with Organizr, it can only show pages that are otherwise accessible from where I want to browse them. Got me thinking, is there any service that works this way? So I only need to access "mystartpage.com" and I can open 192.168.1.105:9191 etc. in it, just like if I was on my home network.

Next time installing Windows 10 disconnect every drive except the one you want it to be installed on. During install Windows might want to put the boot partition on an other drive despite not selecting that. I know this by experience when I also had an HDD connected during install and the boot partition was put there instead of the SSD. Luckily I noticed and did a reinstall with a disconnected HDD.

Found it. Website looks sketchy, no info whatsoever about the creator, but Md5Checker is a free app and works on Windows10. In options uncheck Auto start checking, then drag&drop the md5 files into the window. It will queue the files for checking. I use Total Commander to get all the md5s at once: go to the root folder in which all the folders containing the md5 files are, and with cm_DirBranch it shows all files in current dir and all subdirs. Now I can filter on *.md5, select them all and drop it into Md5Checker.

My calculation was for a new DIY NAS running FreeNAS or OMV with integrated CPU for low consumption. But yes, a used PC would be cheaper.

Good mornang, I have a folder structure that looks like this: folder1 ---files&folders ---folder1.md5 folder2 ---files&folders ---folder2.md5 folder3 ---files&folders ---folder3.md5 And so on, dozens of folders and TBs of data... For integrity check I need to run these checksums regularly. Currently I'm using HashCheck for creating and verifying these checksums. However I can only do one at a time, and I was looking for other programs, but I couldn't find one where I could open multiple md5 files to queue them (of course I don't want all the verifying to run at once, but after each other). What program can do this? Command line tool would be good to, however with certutil I couldn't figure out how to verify with preexisting md5 file, it can only generate the hash.

I'll plug it in to sync (but only by date and size, not content) monthly, and do an integrity check yearly. Yes, startups are harder but for longevity I think a monthly startup is still better than running 24/7 (versus 12 startups and 12 hours of runtime a year). My problem with a NAS is the cost of purchase and operation. I'd need to build my own NAS for around $350, buy n+1 (for parity) NAS drive for $450 and it will consume a yearly $50 of electricity. On the other hand purchasing n HDD for cold storage is an instant $460 saving and $50 for every year (for comparison I could buy a new HDD every 2 year for the cost of the unused electricity).

Thanks everybody. So I will not buy an SMR drive even for cold storage. As for data integrity - since the data itself will not be modified - I will create md5 checksums for everything and run it every year. (My concern with "compare file contents" is that it will tell if the 2 files don't match, but I won't know which one is intact)

Instead of building a NAS and using RAID, I would like to keep a 1:1 backup of my data on a secondary HDD, that I will manually sync every month. What's the life expectancy of the HDD in this case? As I read they give an avg 3yrs of lifespan for a 24/7 running HDD. This one will be running 12hrs a year. What should be done to keep the HDD in shape? Is "bit rot" a real concern? I would imagine having it used monthly even for 1 hour would prevent this from happening. Is there any advice for choosing a HDD? Or it doesn't matter due to the very low usage? Would you recommend an SMR drive if the periodic sync wouldn't mean too much data write?
