For some reason I received a recall notice for one of these from Amazon but I don't recognize it and could not find any purchases in my order history. I vaguely recall my wife might have bought something like this years ago as a gift for some one else but our accounts aren't linked.
Amazon sent me a recall notice about this one, indicating they had it from my purchase history, but oddly I couldn't find it in my own collection of power banks, or in the ones I gave to my wife. I'm worried I might have purchased one for another family member as a gift and not remembered who.
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.
fwiw: You can see when you bought it in your Amazon purchases list, it might help you remember. For example, if you bought it just before someone's birthday date...
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.
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:
> Amprius Technologies, Inc. has never developed or manufactured batteries for power banks. For accuracy, please attribute the certification issue to Apex (Wuxi), not Amprius. Recent reports have incorrectly linked Amprius Technologies, Inc. to a battery certification issue. The company involved is Apex (Wuxi) Co., Ltd., formerly known as Amprius (Wuxi) Co., Ltd., a Chinese lithium battery manufacturer based in Wuxi, China.
> Apex (Wuxi) was once a subsidiary of Amprius Inc. but was never part of Amprius Technologies, Inc. In early 2022, Apex was spun off, renamed, and has operated independently since, with no ties or relationships to Amprius Technologies, Inc.
Even though this is a recall, a bad thing, it actually makes me more likely to buy from Anker than a no-name brand on Amazon. Those no-name brands almost definitely have problems like this (or worse), but we rarely hear about them.
Eh. Anker did the bare minimum to address their liability.
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.
Note that they have another recall for other models going, though their language for those sounds somewhat less dramatic compared to what they used for the PowerCore 10000. More of a "covering our assess" recall than a "holy shit we might be liable for lots of damage" recall.
I have a recalled Anker battery sitting on my stoop, lest it burn my house down. Who on earth (NE USA ideally) will accept this for safe disposal / recycling? Normal battery recycling places don’t want a recalled battery, natch. Serious question, pls help
The RC (Radio Controlled) deal with this all the time. They often wreck huge lipo batteries so they have techniques to discharge them in safe manner. Google or search RC forums.
I have two of these powerbanks, one ordered in 2019 and another in 2021. Amazon sent me scary emails saying these things will kill me. Anker's recall site says I'm not affected and the product is safe to use.
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.
Water won't put it out but putting it in a big enough container of water and leaving it there long enough works. You just need a big enough energy sink + containment.
I would have just trusted Anker in this case. Amazon only knows you bought that model of battery, not whether it was affected. Anker would (or should) know exactly what range of serials were made with the problematic cells.
I think the CT scan tech is cool and the article is written nicely but I don't get the point of this article. Seems like if Anker were using the CT scanner, they still wouldn't be able spot the change. I'm confused.
First off, I love Luma Field. Always incredible to see what's going on inside things. Even just fun to scroll through their Twitter.
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.
Anker is above average, but the bar for average when it comes to Chinese electronics is, "might not burn down your house immediately."
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.
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.
They are good with returns/replacements. My experience with their product quality has been less good though. I had a pair with earbuds from them, I think it had some firmware issue where on an Android phone, volume would go from far too soft to 'blow your eardrums out'. No other buds had this issue with the same phone. They sent me a replacement which was fine, but it could certainly have caused hearing loss.
I also had an USB-C adapter from them (one of those USB-C with power passthrough, HDMI, etc.) it was so badly shielded that no WiFi or Bluetooth connection near it would survive.
I think people generally rave about them because the among very cheap/affordable Chinese vendors they have support that actually writes back and are helpful. The quality of their products is not great though (also see all these power bank recalls). I avoid them now.
Does not mean that all western brands are great either. My wife bought a Satechi USB-C adapter with DP-Alt mode that Satechi claimed would support 4k@60Hz. There was no way to get it running on Mac or non-Mac at 4k@60Hz. So, I did more research based on the MAC address of the device and found that it just a 'recased' version of a $20 Chinese USB-C design (which was specced to only support 4k@30Hz). Not only were Satechi just selling a rebadged USB-C adapter, they didn't even take the effort to check whether the specs that they claim to support are supported (luckily I could return it within 30 days). Also see: https://overengineer.dev/blog/2021/04/25/usb-c-hub-madness/ (in which they find that an Anker adapter is probably a rebadged Ce-Link design)
I don't know about the rest of their products, but their over-ear headphones (Q45 being one specific example) have very weak attachment of the cup to the frame that often cracks and then breaks withing several months of use. This has been well known for at least a decade, and they have done nothing to fix it.
Sounds like they have alright customer service, if you live in a region where it is actually available (not me), and don't care about polluting the environment with yet more short-lived plastic trash. Not really something to support with one's hard-earned money IMHO.
I've found Anker good although when I tried to use my 'lifetime warranty' on a broken USB C to lighting cable I got some run around from an LLM before swearing at them and getting a result. Even so they last longer than the genuine Apple ones.
It was fun to explore the CT scan on my own, then read the article to see what was actually identified, and go back to the scan to find those things myself (despite the limitation of having scans from only one unit -- it was still great!). Initially, I thought there were no details of insides of the battery units, but after adjusting the settings, I was able to see the internal layers!
This scrutiny actually makes me more inclined to buy Anker products. There's more trust in a company that will transparently communicate, correct mistakes and raise the safety bar for future products. It also brings to light issues with other manufacturers in the supply chain.
I had one of the affected models. I filled out the recall form yesterday, and they emailed me this morning to let me know the replacement has been sent. They are pretty good about standing behind their products
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 and I force my partner to do the same to her irritation. Last week her MacBook became spicy overnight and I had to rush to Apple Store morning, the price for battery replacement was more than the price of that MacBook in used market so I had to buy a new MacBook.
I miss the good old days where I could take the battery of the Nokia phone and spin it on the table to see if it's become spicy. I pray to EU gods to please force the manufactures to bring back user replaceable batteries.

How is throwing a potentially damaged lithium battery into the trash, where no batteries of any kind should go, cautious?
Would you want to tear down Lithium batteries??? It’s slightly hazardous…

Do you have any reccs you enjoy watching? Asking for a friend :)

If you try their provided troubleshooting instructions, your port may return normal again. Worth give it a try.
