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.

The scary thing is you can't put the fire out with water. Your only option is to run.

Enough water will suppress the fire and deprive it of heat for thermal runaway and keep nearby items from catching fire.

If you stop the water, it may reignite or smolder and produce smoke, but water will work to combat the fire.

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…

Amprius has released a statement: > 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 b…

According to the recall notice, these powerbanks were "manufactured between January 1st, 2016, and October 30th, 2019" [0], so that was very much during the time before this says that they were spun out into a separate company.

Going from that last quote, they would in fact have been made and sold by Apex(Inc) at the time it was a subsidiary of Amprius Inc. and claiming otherwise seems like deliberate deception.

Their own website makes clear that Amprius Technologies Inc and Apex (Wuxi) are related in the description of their CEO, who served as CEO of both companies simultaneously. [1]

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…

I don't get how it's possible that nobody (other than Tesla) can manufacture batteries in the West? 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…

I don't want to, but I can't stop thinking that DJT might be kind of right on this one. Each of economical blocks in this world such as EU/US, China, or Japan, don't mutually co-depend enough for any foreign currencies like USD or CNY to be single universal representation of values.

The current US administration's weird argument is that the USD values exchanged in inter-national trades must be symmetrical, but if you think about it, the amounts just don't mean anything. Balancing the amount only, like forcing the other party buy tons of American stuffs, won't solve it. The exchanged amounts only fuel philosophical border towns and dependency chains don't penetrate deep into foreign economies. The prices are not manipulated, it's just random.

The US has enough of everything to make batteries, you just can't fight something sold at completely arbitrary prices on economical grounds.

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…

Is your house especially warm? I’m not doubting that it happened but I’ve had very different experiences (one battery problem in a couple decades) and am curious what might explain the difference other than bad luck.

I live in India, both in North and South at different times of the year and yes it does get extremely hot during summer but I've been very careful and monitor battery temps at all time.

My theory is just I've had a bad luck with batteries.

Your prayers have been (partially) heard. The EU Battery Regulation of 2023 demands that starting February 2027 batteries in all devices have to be user-replaceable with commercially available tools (or for watertight devices or some special device categories replaceable by an independent professional), that replacement batteries have to be available at reasonable prices and that use of third party batteries should n…

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.

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

I regularly check the electrical outlets and the main supply; it's mostly just my bad luck.

Must cost a fortune for business to operate in such a low trust environment. Free market types take note: good regulation and “red tape” can actually help free enterprise

Isn't this a matter of tort law rather than regulation?

There's still lots of poorly produced electronics that treat NiMH that is within its normal operating voltage as being out of juice, and either nag you or shut down completely. My supposedly high quality Logitech mouse is one example (probably not buying anything from Logitech ever again, they're one of those brands that are coasting on their old credibility).

A device that won't work with NiMH due to voltage will also only use about a third of the energy in an alkaline. Poorly produced is an understatement. My Logitech G604 works fine on NiMH. The calibration for reporting battery charge as a percentage is off, but it runs for months.

As an aside, pretty much all the g604 is will end up with double click reliability issues or an inability to hold down the mouse button and drag. But you can easily replace the switches or there's vendors on eBay and AliExpress that I'll sell you a circuit board with the switches pre-soldered for replacement.

Logitech no longer makes the g604 :(

I have family in the auto industry, and they have similar stories. They'll get a shipment and it'll be out of spec. So they contact the vendor and the vendor will just say, "No, they're fine. Parts are good." No, they're out of spec and you need to fix them. Look, I can show you. "No, parts are good." And you'll go around and around like that. They won't care and won't budge. Until you say, "Well, since these are out…
