(Notably, this page mentions "Anker has received 19 reports of fires and explosions. This includes two reports of minor burn injuries not requiring medical attention and 11 reports of property damage totaling over $60,700." Puts it into context! That's not a house, but with numbers like that, I wonder if a couple cars were destroyed.)
There's also Anker's product recalls main page:
https://www.anker.com/product-recalls
which adds a few other models with different enclosures but presumably with the same upstream manufacturer to the recall.
I mean, there's probably very good ROI on this marketing; I'm not saying they're foolish or selfless. Just that it doesn't cost them that much to do, so it's a win-win for everyone.
actually no let's not blend the lithium, forbidden inhaled powder
Here's a blog post with interesting information that just so happens to advertise how you can use our product
A) Keep using it, even if they do hear about the recall
B) Throw it in the trash can

Are you nuts?
X-ray inspection is not that rare, there’s even small assembly houses here (Spain) that can do xray automated inspection.
This has been standard for years to the point I’ve been sent forms for assembly houses RFQ where there are checkboxes for xray inspection, and I haven’t handled a serious assembly development in ~4 years.
What’s new and they’re advertising here is CT, which is another level.

The recall is concerning, especially since once they started with the one, they quickly added several more to the list. I've ordered at least 17 Anker products over the last ten years (not all of them power banks). I pay the premium over cheaper external batteries, and I have advised my family in the past to do the same. This is ostensibly because they are supposed to be the guys that don't explode. If I can't even take that for granted, then there's really no reason to maintain customer loyalty. There are countless other, cheaper brands available online from no-name Chinese companies.
For now I don't avoid them, yet. Definitely not switching to a random cinese brand instead.
I also only buy portable battery models that I believe will sell or has sold many thousands of units so any widespread manufacturering defects should become apparent sooner.
Just also darkly hilarious — “I only buy <PRODUCT> with a history of product recalls”.
There was a time in which we used to avoid such things…
Part of the price of cheap shit.
Anker on the other hand is a recognizable name with a brand image. So they need to do right to keep their trust.
This is one of the Chinese reports on the issue: https://m.thepaper.cn/newsDetail_forward_31048287
Excerpt from the report above (translated using Google):
> The Paper learned from an insider that Anker Innovations' battery cell supplier is already a leading battery cell supplier in the industry, and did not inform customers after it changed materials. In addition to Anker Innovations, the supplier also cooperates with leading power bank brands, so the impact is huge. Although Anker Innovations did not name the supplier, an insider pointed out that the supplier was Amprius.
UPDATE:
There's an exclusive interview by 36kr with one of Anker's VPs:

*unless the product is visible external packaging.
This is all common knowledge, proven by example after example that it's necessary to have zero trust. It's truly an adversarial system. All the extra engineering effort for IQC is still cheaper. And, there's rarely an alternative to the amazing manufacturing ecosystem that is China.
After tracking down several of these types of issues, it appears that the Chabuduo mindset [1] is a very real thing.
I can only find https://youtu.be/3ZTGwcHQfLY but earlier this year it was all over YouTube.
US manufacturers aren't doomed: they already don't exist, and the infrastructure needed to support them also does not exist.
Close to impossible without a serious time investment and dedication.
Only to someone not involved with Chinese manufacturing.
It's not too hard to find good manufacturers that you can trust. If you do, they will be operating with this same mindset, completely distrusting everyone else. Great! You're done, right? Well sure, until management changes (this happened to us once).
The only difference is that is more difficult to hold Chinese suppliers accountable. Americans will happily cheat you as well.
I did not have too much experience with US manufacturers. I however can talk about Canada and Brasil. My experience with Brasil was stellar. Canada - you better fucking watch. As for China - I did order directly high power DC/DC converters. Those were available in the US and China. China came 10 times cheaper ($25 vs $250 apiece). The devices where we have installed those still work like a charm more than a decade after.
I have never had to deal with an American supplier "downsizing" wire from one guage to the next smaller for example.
Nor as linked above, including extra electronics to exfiltrate credit card data from terminals.
For example (hope I didn't mess up the details, it's been some time since I read it), a cosmetics manufacturer vendor replaced shampoo bottles with ones made with less (thinner) plastics multiple times, untill they started being destroyed in shipping... without notifying the company that ordered the shampoo... and then wanted more money for the "better" shampoo bottles.
Also some very questionable practices:
-----
The hair gel that we produced at the factory was green. One day, I noticed that the worker who filled the gel bottles had a skin condition. His hands were covered with the slick formula, and beneath the green, shimmery layer, I could see that the skin on his hands was peeling. Small, raw patches of flesh were exposed, and you didn’t have to be a dermatologist to see that his skin was infected.
“We should probably do something about this one,” I said to Sister, trying to sound calm, while in my head alarm bells were ringing.
Sister did not see the point. “Why?” she asked.
“It might be a health issue?”
“But the worker has done nothing wrong. It’s just an allergic reaction.”
Trying to press the matter, I suggested that the worker might contaminate the product.
Sister twisted around the argument. “How can he harm the product when it was the product that caused him the harm?”
IMO high tech cost optimization is like the opposite of chabuduo - it's not half-assing, but over value engineer under pressure. The PRC's "amazing" manufacturing system fosters adversarial competition down the supply chain because there are so many competitors, packed with technical talent incentivized to value-engineer the shit out of everything to squeeze out fractions of a RMB more per unit. Some engineering team probably poured thousands of man-hours and retooled $$$ manufacturing lines just to gain a tiny margin edge. Sometimes that backfires. But the pressure isn't about laziness - it's involutionary effort. The result is still a zero-trust environment, since when manufacturing base is so dense, everyone incentivized to cut corners or optimize/tweak silently, they usually do, forcing everyone upstream to stay hyper vigilant. So we end up in default equilibrium where it's cheaper/more optimal to squeeze downstream and inspect.
> and that the product being given to you is even yours (delivering a knockoff at the final step, and reselling yours on the gray market).
Culturally, chabuduo is more of an excuse/greed of the lazy to convince you it’s close enough [that it won’t make a difference to you] and they’re too lazy or out of patience, for many reasons they also don’t want to explain to you.
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 won't notice" and worth a try. It's definitely a giant pain in the ass, and adds a ton of expense and friction to the process. Lots of stuff you simply cannot source from any other country though - even if you do, the supply chain usually traces back to China anyways so all you're doing is adding a middleman layer to the problem.
It's extremely important to set very explicit and strict quality parameters and specifications prior to any deal you do with a vendor. Even then you will miss things that will later be argued about. The more you can specify the better, otherwise it will be seen as negotiable/changeable.
A lot of folks used to living in a high trust society get really taking advantage by this. Any vendor sourcing from China and not implementing an extreme level of QA to the process is being negligent, and I assume that's quite a lot if not the vast majority.
It a glance this feels insane. Batteries are in everything and such a basic need.
How is it possible that buying through known scammers with tons of QA is still cheaper than manufacturing in the West?
Obviously for Tesla it isn't cheaper to buy from China, so why is it thought to be cheaper for the rest of the West? Is it purely scale?
It is remarkable that Tesla was able to figure it out.
It's still that way, but a bit less so. The intractable problem now is entire supply chains end to end do not exist in the west. If you wanted to start a battery company you are going to have a really hard time sourcing all your components in-country. All the way down to the inks used in printing the serial number on stuff.
In the end of course it all ends up as a cost, but even if you somehow dropped all environmental standards and set the cost of labor to match China today it would take decades just to get the institutional knowledge and infrastructure back.
(no idea if that’s the case, I have no specialized knowledge about batteries, just venturing a guess)
The battery packs themselves have been pulled apart and studied by everyone, pretty much all EV manufacturers are doing similar things anyway, so no real special sauce anywhere anymore.
Now there are more mature EV players in the game, innovations are happening from many manufacturers now (not just Tesla leading anymore) and then everyone else converges on the best ideas.
They are also starting to build their own lfp batteries at a new factory in Nevada, though it sounds like those will be for stationary storage.
As for designing them, this was a good interview with the CEO of CATL pointing to talent pipeline issues. We don't train enough chemical engineers: https://www.youtube.com/watch?v=5VIXjjw4u9A
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 text on the metal panel. They sent it to us with not a care in the world.
They got sent back and told to rework the panels completely (strip them). And what did they do? Not strip the paint fully and now components that slot into the panels do not fit because there's basically an extra 1/8" of paint on the inside edges.
The worse part due to our own internal politics, we couldn't just let use our significantly more reliable Chinese supplier who has easily eaten a million dollars in errors before.
This US supplier is charging us for every single bit of their incompetence.
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 and/or care enough for it to matter. That sort of thing doesn't seem to happen as much in the West.
I do agree that the reliable Chinese vendors will make things right at their expense if you can prove that they did not meet what they agreed upon. This is basically how I choose to deal with a vendor or not in China (or anywhere, for that matter) - I know stuff will happen, but how hard did I have to fight for them to make it right?
I don't think that's entirely fair, since there's definitely some naivety here. "What happens if there's a mistake" needs to be the first thing you ask, when working with anyone. If you don't, you've both agreed to an uncomfortable argument, when things go wrong. Get it out of the way at the beginning, but expect to pay a little more for not relying on hopes and dreams of perfection.
And, there's a good chance that if you read the fine print, you explicitly agreed to this.
A number of the integrators I worked with added rules banning customer-supplied CPUs because Intel would give away "working" product to educational/other institutions that, uh, did not POST, and it was such a headache so often that they banned using the product.

Recent reports have incorrectly linked Amprius Technologies, Inc. to a battery certification issue.

Also, repeating your sentiment, for all the tech gadgets.. bluetooth speakers, I'm looking at you.. why not have replaceable batteries for those? There have to be enough vapers now that the knowledge of this type of battery as distinct from the old alkaline ones has passed into mainstream consciousness. This would be a huge selling feature for me.
The reasons I see are that it is because the rechargable li-ion are more dangerous and a fire hazard, but is this really true? As with most anything that can carry a risk if misused, I can find a few dozen instances where a vape battery went awry, but surely the benefits outweigh the concerns?
Edit: I do understand the irony of saying this on a post about when they do go boom.
Flashlight and vape enthusiasts are mostly adults who likely trend as all three of: older and more knowledgeable, more likely to take and accept risks, and more willing to pay a premium for the benefits of replaceable batteries... and the companies that make vapes and high-powered enthusiast flashlights are probably less worried about a customer suing them over a battery issue than a large toy manufacturer. If you're a vape company, you have bigger safety issues to worry about -- like the normal operation of your products :)
There are no mercury alkalines anymore for general consumer use, those collection bins were removed from stores in the 90's and they can be disposed of with normal waste.
I'm with you on the risk/benefit calculation. E-waste is bad, and the option to bring a spare battery makes a lot of products more useful. A Li-ion cell can be dangerous if mishandled, but less so than a jug of gasoline or larger power tools.
This can be considerably mitigated by sticking a protection circuit on the end of a cell, which makes it no more dangerous than the proprietary Li-ion batteries used in things like cameras.
I do often stick unprotected cells in flashlights that came with protected ones. It's important to know whether the flashlight can over-discharge the cell, but most can't, and it's important to not short-circuit them. I suggest people who don't want to learn about batteries stick with protected.
From memory, the max output was about 20~30W for the bigger models [0]. For 2 cell types it gives 10W, so barely good enough to slowly charge a smartphone.
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 rotate in new batteries), use disposable batteries from the corner shop in an emergency.
If they put in a round cell I'd stay away. I usually replace the cell with one I know is good and check the circuit for protection. Wouldn't be the first time I've seen something with no over or undervolt protection whatsoever.
No phones use this chemistry. I have no idea what you're on about.
>Wouldn't be the first time I've seen something with no over or undervolt protection whatsoever.
Even the cheapest lithium ion charge controllers have overvolt protection by the nature of how they work. What can happen however is a controller could be specced to charge to 4.3V per cell and a 4.2V cell is instead installed. This is a problem.
I thought we were discussing a power bank not a phone.
No-name batteries are often way lower capacity than advertised, which means less stuff, and therefore less densely packed and less stuff to burn.
I am not saying that these batteries are safer, or that it is not a scam, but the fact that these batteries are lower capacity can compensate for the sketchy build. Power electronics is another story, so while the battery may be ok, the charging circuit may not.
Reminiscent of the tylenol case study, handled a tough situation correctly and it's still on the shelf.
They won’t pay for devices that Amazon says are in scope, but the black on black serial number is illegible.
For devices that are covered, they advise you to not dispose of them at a retailer like Home Depot that accepts lithium batteries, but provides no means to safely dispose of this fire hazard. So I got my $40 payment, but I assume now that will disclaim any liability when my house or car goes on fire while I try to find a facility that accepts dangerous batteries.
My current perspective, recall or not, is their quality is no different from the alphabet soup companies selling identical looking (and possibly identical) items.
It seems like the overheating issue is “not thier fault,” but part of being a trusted brand isn’t just recalling but vetting suppliers and the components they receive.
Are models sold in some regions different/known-good?
Should probably at least discharge it to be safe(r), I guess.
I'm not sure who to trust, but I've erred on the side of caution and trashed the batteries. Because it's not worth dying in a fire over $30 in batteries.
That is not true. Please don't spread misinformation that could lead to deaths or people losing everything they own.
You can put out a Lithium battery fire with a class-D fire extinguisher. If you don't have one available, you can isolate the burning battery by surrounding it with sand or other inert, dry substances to keep it from spreading until the fire department arrives with proper equipment to dispose of or extinguish it.
Also you can keep things near the battery wet.
Would you want to tear down Lithium batteries??? It’s slightly hazardous…
Second, Anker is one of the few companies I actually have a very high trust for. A few years back I bought a wall charger[0] from them, it has 2 USB-C and a Type A. A month in, one of the Type-C ports wouldn't charge if the other port was being used. If you send a support ticket they annoyingly give you a response with very basic trouble shooting. But if you respond to that you get a person. They just sent me a new one right away (<10 days) and there was no need to return the charger or anything. So I still use it, just blocked the bad port. I gotta say, whenever I encounter good customer service I become loyal.
I wanted to say this because I think a quality matters. Quality often takes nuances and this can often run counter to maximizing profits (Lemon Markets and all that). Looking at Luma's report, I don't get the indication that they had this issue because they were cutting corners but looks like it must be upstream[1]. But am happy to see they were giving gift cards along with the recall. Companies should minimize mistakes as best as they can, but it is important to judge them by how they handle mistakes. It can be easy to get caught in the negativity but I personally don't think I'll stop buying Anker products.
For reasons probably bordering on OCD, I watch a LOT of teardown videos of various electronics. And one thing that always strikes me is how a company with a product will routinely and often change what's inside, while the model number and exterior appearance stays the same.
For example, I wanted to buy a big 12V LiFePo4 battery and all of the cheapest ones are on Amazon. Amazon reviews are generally garbage because they're all borderline fake (from useless Viners, or wanna-be useless Viners). The only "honest" reviews of these I could find were YouTube teardowns where they basically have to destroy the case in order to take it apart. I would watch a teardown of one popular battery, and then run across a different teardown of the same model from someone else and the internals of each would be completely different. Completely different cells, battery management board, wires, construction everything. But they both looked identical on the outside.
Finished product manufacturers in China rarely have a consistent supply chain. They are negotiating suppliers and batches of components constantly, and are constantly re-engineering everything about the product, except for the external appearance of the case. This Luma Field article confirms what I've already run across myself.
And it seemed the main issue as identified by Luna was not with the cells but the bank design itself.
> If the recall is affecting units made with 18650 battery cells from multiple suppliers, that suggests the root cause of the recall stems from elsewhere in the power bank. We next focused on the PCB and assembly of the board with the cells.
> We can measure the distance to quantify how dramatically the gap between the positive and negative bus bars varies across the three units. In PB1, that distance is only 0.52 mm
But it is still upstream since AFAIK Anker just rebrands other products.
If you try their provided troubleshooting instructions, your port may return normal again. Worth give it a try.
