Does anyone know a good, as in reliable and will not burn the house down, brand of USB rechargable (preferably type C USB) AA batteries? I got a batch of these, but the labels peeled on a couple on first charge due to heating up so much, and one of them also lost the "nub" of the positive terminal (it fell off). I know, I know, Ali batteries, but I can't find USB rechargable AA batteries anywhere locally. Even at a specialty battery shop the guy wondered if such a thing exists.

I've not seen that style of battery in a very long time and I've never heard of any of them being anywhere close to good. It's worth it to get a decent charger and some quality rechargeable batteries imo.

Yeah I've found that even Energiser Ni-MH batteries can be poo poo I have mostly wound up (via survivorship) a collection of IKEA, Amazon Basics, and Eneloops. Getting a decent charger that can independently charge single cells at the same time is definitely the way to go - I kinda wish I had spent a bit more and got one that was a bit less cryptic in its display tho. (Nitecore i4)

The more expensive Ikea Ladda batteries are, as far as I can tell, the exact same batteries as Eneloops. I'd also suggest just getting those, with Aliexpress not only are you getting mystery cells that are full of sawdust, they're also physically much smaller due to the USB connector and circuitry taking up all the space. I did get a USB 18650 for a flashlight and it works fine enough at the cost of much smaller capacity.

Idk if they're on aliexpress, I got mine on Amazon, but EBL brand rechargeables haven't disappointed me yet, you need to also get their little charging station instead of plugging the individual batteries in directly, but the charging station is powered by USB and fits AA and AAA in any combination And the batteries are rainbow coloured :3

gently caress a 10' pole, they dont make sticks long enough for me to touch batteries that came from ali with. I got a Duracell set from Costco and also a bunch of amazon basics, which I charge in both the Duracell charger as well as a really old Rayovac thing from 15 years ago that still works but I lost the original batteries for.

(Nitecore i4) I've got a Nightcore USM4 that I'm very happy with. At some point I'll open it up and swap it to use a USB C connection instead of Micro USB. It's been great though.

From memory the ladda range came out shortly after eneloop developed the super low self discharge cells and that was always a dead giveaway as a feature on packaging that you were buying eneloops with different branding. Not sure if that still holds true

I'll also vouch that IKEA batteries are good stuff, they also sell a really slim usb powered battery charger called Vinninge that I take for travel, might be a good option.

Strong Convections posted:That is the weirdest battery I have ever seen, I can't even imagine how it would be hooked up inside to work (also doubting the 2600 capacity). I can think of many ways it could be hooked up internally. They're all terrible and involve wires that really aren't fit for purpose. They also leave no room for proper protection. I can see fires happening when someone tries to charge and use them simultaneously. Unless the manufacturer has discovered some new magical battery chemistry then no, it's not 2600mAH.

Yes, a more literal way to say what I meant was "I'm horrified/terrified to imagine how such a battery is hooked up inside."

I can’t find the video for the AA version, but I did find Big Clive having a go at the PP3/9V version of the same thing here: https://youtu.be/dR_RusM99no

I started on Trek comm badges that all looked great in the ad but terrible in the reviews, then to star trek hoodies and into gimmick hoodies (those “3D print” ones are crap) and finally found the good stuff. Very sad frog hoodie  This one is kind of cool too, shark with a beak?  Some cheap cosplay items, I think it’s the attitude that makes it work (I can’t even remember if this was for the phaser or jacket but it’s just great)

I won't know how complete or high quality that knockoff-LEGO Hogwarts set is until after Xmas when we'll put it together, but it sure did get here with almost unbelievable speed! I ordered it on 9/21 and it was delivered -- from Hong Kong! -- on 9/27!

Ordered a $2 thimble to go in my sewing box, because I could have used one while stitching denim the other day. And I got this message from the seller, the link goes to an AU$0.80 “Shipping Fee” item.

couple ali packages came in this week $12 Aliexpress kill-a-watt - https://www.aliexpress.us/item/2255799968709291.htm  here it is with a standing fan plugged in. seems like it works correctly. i don't really have a way to test how accurate it is. the 729 at the top is because i ran it with the fan plugged in it for 7 hrs 29 min yesterday to see the kWh usage.   Bought two of these cute little digital thermometers. plan to have one inside and one outside. https://www.aliexpress.us/item/3256803917081380.html little happy baby picture is apparently a "comfort" indicator. not sure what the parameters are for determining if it's a comfortable temp and humidity. uses a single cr2032 battery  $16 CO2 detector - https://www.aliexpress.us/item/3256803560488389.html i was pleasantly surprised when i turned it on. bright clear screen and usb-c for charging. it seemingly works - numbers go up when you blow on it  again don't really have a good way to test its accuracy. open to suggestions though  would be cool to have a co2 detector that can log its measurements so i could actually collect the data. the air quality meters that I've seen with those capabilities are $$$.

raspberry pi based co2 monitors seem to be a fairly popular project and you could definitely do logging that way. could even use a pi zero and run it off battery for portability. idk how accurate the cheap sensor modules are but it's probably the same sensor thats in that thing anyway of course if you don't already have a raspberry pi then lol nevermind

It's pretty amazing how accurate that cheap poo poo from Aliexpress is. I bought a weather sensor (temp, humidity, barometer) from AliExpress for about $4 (including shipping) if I remember. It was just as accurate as the $15 BME280 I bought from Adafruit. I have no idea what I did with it though; probably in a project box in a stack of unifinished projects.

thanks for the cool suggestions. i do have a raspberry pi sitting around and some arduino boards. maybe I'll order some more sensors off ali and put something together. but yeah, this is just a curiosity about air quality in my house. I'll definitely check out that airgradient thingy and the PM2 sensor sounds cool.

I had a bunch DHT-something sensors which are even cheaper at like $1 but were pretty poo poo, and the BME works perfectly.\ You're probably right about them being actual BME boards. They were stamped as BME280s on the PCB and worked with the Python BME280 libraries from Adafruit.

I was tired of putting batteries in thermometers, so I bought an analog thermo-hygrometer off Ali. Either my bedroom has an extremely stable microclimate or the thing doesn't work very well.  I'd been eyeing that little digital one; can it display Fahrenheit?

Ordered and received this stick-on / suction touch screen game controller real quick. I am mightily impressed after messing around with it for a few hours. Probably going to order another just to have a backup. There’s a lot of different styles for touchscreen controllers like this and I don’t know how it compares to any others but in judging it for what it does: it stays where it’s put, it self centers, it works really well for games with d-pad style controls. And it comes in a little plastic memory card style case for when you’re not using it. The suction works surprisingly well, I can’t accidentally move it while using it but can pick it up off the screen really easily.

Pure CO2 can displace breathable air so they are put in kegrooms etc where you have large tanks of the stuff that could leak and cause problems for life. You are definitely gonna know that something is wrong pretty fast in a high CO2 environment (unlike CO or N2)
