We're talking about culture differences about perception of accountability. Not necessary but definitely on topic.

Cultural differences is an easy sub for racism? Not suggesting bad faith but when it's hard to also take commentary on Asia with good faith here.

I don't know, assuming all cultures should be functionally equivalent seems pretty imperialist to me.

I work in manufacturing in the US. Incoming quality control, for Chinese vendors, is necessarily set up with zero-trust. This isn't a "trust but verify" sort of thing, it's strictly "do not trust". Assume that, at every step of the chain, there will be a lie: change of process, material change, collected data, and that the product being given to you is even yours (delivering a knockoff at the final step, and resellin…

Yep. Anything I get from China, even from a vendor I have done lots of business with in the past gets at minimum random samples inspected and tested when appropriate. Every single shipment, zero exceptions before use. So many things are caught. At best there is a lack of QA on the Chinese side, but it's definitely worse than that. They have no qualms sending you known-bad items, and just see it as "maybe the customer…

so LLM-like)

i dont mind double-sourcing components, as long as it passes the QC/QA and certifications. Even Apple iphone(tbf, also made in China) double-source important components inside their phone(modem)

> Even Apple iphone(tbf, also made in China) double-source important components inside their phone(modem) Samsung goes a bit further. Depending on where you buy e.g. a S23 FE, you'll get entirely different SoC architectures - the US model ships with Qualcomm Snapdragon, the international model with Samsung Exynos. [1] https://en.wikipedia.org/wiki/Samsung_Galaxy_S23

At least Samsung is using different model numbers for that. And it's not exactly supposed to be hidden since they support different frequencies.

Other mitigations are possible, such as a battery compartment designed for cells that are 69mm long, as is typical for protected cells instead of 65mm. I'll admit I complain about this when reviewing a flashlight (use longer springs so it's not picky), but it's likely the right choice for many applications. It's not the right choice for all applications of course. Products intended for children and that are particula…

A battery compartment that is " almost the right size" is going to encourage unfamiliar users to do stupid things. https://budgetlightforum.com/t/my-18650-batteries-are-about-... > The batteries that come with the light are perfect, but all the panasonic 18650s I have purchased are about 1/8 (3mm) too short. > I was thinking of using aluminum foil.

I don't think it should be required that devices protect users from unsafe modifications even if they're foreseeable. I can also tape down the safety bar on the lawnmower, remove the guards from the circular saw, and take the firing pin block out of the gun. I'm sure people have done all of those things, and some have regretted it.

What I'm advocating is a bit beyond just repairability; field-replaceable batteries the ability to charge spares externally, and the ability to share spares between devices are substantial benefits.

I've had my share of spicy pillows ranging from iPad to power bank from upstart company which became spicy after using it for just 3 times[1]. I've been overly cautious of batteries for several years now, I charge my devices with 1A charger and keep it between 40% to 80% . I now carry a single 18650 cell power bank instead of those 10,000 mAh, 20,000mAh power banks. I don't sleep with phone, tablet or kindle on bed a…

This honestly sounds like the electricity service line into your place is fucked slightly and it is gradually destroying your electronics.

To damage batteries it would have to get through two separate power converters. I'm skeptical of that.

Thank you EU, Although I don't live there I'm hoping the manufacturers wouldn't take the effort to make EU specific models of their devices and the benefits are reaped throughout the world.

doubt it, apple still does usb-c only for europe and the rest is stuck at lightning connectors.

So that's wrong but I'm particularly focused on the word "still". How long are you under the impression they've been doing this?

FWIW this has caused a big storm in China. The root of the issue is known to be caused by the battery cell vendor Amprius changing the battery design w/o notifying the power bank manufacturers. AFAIKT Amprius lost the 3C certification (a certification in China) because of this incident. This is one of the Chinese reports on the issue: https://m.thepaper.cn/newsDetail_forward_31048287 Excerpt from the report above (tr…

Sounds like “fail fast, fail often.”

Anker should know better by this point. Changing specs without notifying customers is the basic formula of every Chinese manufacturer. They must have gotten lazy with their internal QA/QC processes and random sampling.

It clearly isn't the "basic formula" if it was so out of the norm it caused a national controversy and got the vendor's certifications removed. Your bitterness is showing.

While I'm sympathetic to this sort of reasoning, there are many, many examples (even in the US!) of bad behavior being so commonplace that it's expected, and no one gets punished until one sticks out enough (or fucks up hard enough) to force the local authorities to actually pay attention and slap them on the wrist. In this particular case, I think it's entirely within what we would expect from the CCP to say "you got caught and made China look bad, you're going to face consequences".

>A lot of folks used to living in a high trust society get really taking advantage by this. Everything you describe happens even with US suppliers. Dealing with one right now that sent us sheet metal that was painted + silkscreened incorrectly (a very large symbol was completely dropped by them). They proceeded to "refinish" them, wrong by silkscreening a second time which completely degraded the quality of smaller t…

Presumably this is an "honest" mistake via incompetence by the vendor, with horrible follow-up to remedy said mistake. The same of course happens with every vendor located anywhere in the world. It's getting much worse lately in the US as far as I can tell. The difference though is your vendor using a lower grade metal than specified, knowingly and with intent to defraud since they decided that you might not notice a…

> That sort of thing doesn't seem to happen as much in the West.

This happens a lot in Italy. There was even a huge scandal about how olive oil isn’t pure olive oil.

100%... I'm seeking products that take AA or AAA batteries instead of built-in lithium batteries, for the same reason.

Same, but different. I have bought maybe hundreds of rechargeable AA/AAA batteries over the last ten years, and chased as exclusively as possible devices without built-in rechargeable batteries. Anything with a built-in battery is nearly always e-waste within 3 years, while I've had AA/AAA devices that are 5-10 years old that are fine. Pop the batteries out when in storage, never need to wait for it to recharge (just…

Exactly. I still use portable flash units (speed lights) that are now well over 20 years old, while a lot of the newer units have built-in batteries that will fail in just a few years. And it's an extreme example, but I still use my Game Boy DMG, which is a 36 year old device.

All electronic devices are eventually e-waste, but devices that use AA/AAA can last decades longer. I only buy something with a lithium ion battery when there is almost literally no alternative (essentially phone and laptop).
