ROMOSS power banks exploded, ROMOSS power banks' 3C certificates were revoked, and ROMOSS power banks were recalled —

On the surface, it seems that ROMOSS only produces harmful junk, and this brand shouldn't even exist?

There's some truth to this statement, but it's only true on the surface. In fact, the root cause of power bank explosions isn't here.

Presumably, you've already learned from the news that ROMOSS, a company that started with mobile power banks, has run into trouble. Several of its mobile power banks caught fire, ultimately leading to:

The recall of 490,000 mobile power banks with safety hazards, the revocation of almost all 3C certificates for its mobile power banks, and the removal of all mobile power bank products from its official flagship store. It feels like the brand is about to disappear...

Unexpectedly, right after ROMOSS ran into trouble, Anker, a high - end mobile power bank brand next door, also issued a recall notice. The number of mobile power banks involved reached as many as 710,000, even more than ROMOSS...

Later, people found that the real culprit behind the large - scale recalls of ROMOSS and Anker is the battery cell supplier behind these two power bank brands — a battery manufacturing company called Amprius.

According to exclusive information obtained by our Chaping editorial department from the supply chain, the whole incident started when Amprius outsourced the production of two batches of battery cells to a battery OEM factory in Jiangxi.

As a result, this outsourced factory illegally replaced the raw material of the separator between the cathode and anode of the battery during the production process, leading to a risk of failure of the separator between the positive and negative electrodes of the battery. Eventually, the positive and negative electrodes of the mobile power bank came into direct contact, triggering thermal runaway and causing an explosion.

It is said that these batches of battery cells entered the market a year ago. After more than a year of use, the problems with the inferior separators finally began to surface.

Careful readers may have noticed that there was a passage in Anker's earlier recall notice for its power banks: "We found that some batches of industry - standard battery cells from a certain supplier had unauthorized raw material changes, which may lead to the insulation failure of the separator in a very small number of products after long - term cyclic use."

This also corroborates our own sources.

So, even if you haven't bought a ROMOSS mobile power bank, it's best to check the model of your own power bank and consult the customer service to see if there's a recall notice.

Because it's not just ROMOSS. In theory, all mobile power banks that use these two batches of Amprius battery cells are at risk of explosion.

However, although ROMOSS is one of the innocent victims in this incident, there also seem to be some problems with ROMOSS itself —

If you simply search for "ROMOSS mobile power bank causes fire", you'll find many reports from a few years ago, but they didn't attract enough attention. There's also a more recent example. In March this year, Hong Kong Airlines Flight HX115 made an emergency landing due to a fire in the luggage compartment. The recently announced accident report clearly stated that it was a ROMOSS mobile power bank that overheated and caught fire...

Moreover, our colleagues quietly mentioned that they had previously written a post about rights - protection regarding the self - ignition of ROMOSS mobile power banks.

Even more comically, there's a victim of ROMOSS power banks in our editorial department — our motion designer Gin's ROMOSS mobile power bank overheated, swelled, and became severely deformed.

We tried to analyze the reason and finally found an announcement from Minchuang Electronics. It was found that ROMOSS didn't integrate the NTC thermistor, the most basic over - charge temperature protection device, into its mobile power banks until 2019... This is actually a rather irresponsible behavior among mobile power bank manufacturers.

So, in this explosion incident caused by Amprius battery cells, ROMOSS is a victim.

But if we really dig into the past, ROMOSS may not be as innocent as it seems. This is exactly why ROMOSS's reputation hit rock bottom during this wave of incidents.

So much so that even under our posts about the problems with Amprius battery cells, some people said that we were paid by ROMOSS to divert public attention. It shows how much ROMOSS is hated in the public opinion field.

So, if I were ROMOSS's public relations person, I'd definitely stop making excuses and just kneel down and admit mistakes and recall the products. And that's exactly what they did. However, there was a funny little episode during the mobile power bank recall.

When ROMOSS announced the recall, it said it could provide a free replacement with a brand - new mobile power bank of no less value than the original product and meeting safety standards, or handle returns and refunds. But the return plan for users was to "ask users to send the products by express delivery"...

Come on, don't you guys remember why these mobile power banks are being recalled? So, SF Express and JD Logistics immediately refused to accept individual shipments of ROMOSS power banks.

So, later, ROMOSS came up with a new recall plan: First, ask users to try their best to drain the power of the mobile power bank, and then soak it in salt water for 24 hours —

This is equivalent to allowing the positive and negative electrodes of the mobile power bank to discharge slowly through the salt water, depleting the energy of the battery cell through this method, eliminating the risk of explosion, and then sending it back to ROMOSS.

Coincidentally, we found an idle ROMOSS mobile power bank in our studio and followed the actual process. Although the whole process seemed rather strange, after a series of operations, we found that there was no problem. After leaving it for two nights, the power bank was indeed sent back.

On the other hand, after learning from ROMOSS's experience, Anker's recall process went much more smoothly. When recalling their mobile power banks, they sent an explosion - proof bag to users in advance...

As of now, all 3C certificates for Amprius's battery cells have been suspended. Some 3C certification certificates for mobile power bank brands such as Anker, Baseus, and Ugreen have also been suspended.

Then everyone recalled their products, and it seems like the matter is over?

But just two days ago, the Civil Aviation Administration suddenly issued an announcement, effectively "killing" almost all power banks released before August 2024 — even if they have passed the 3C certification, they can't be taken on the plane if there's no 3C logo on the body.

You probably already know that the key problem this time is those batches of inferior battery cells, and they even have 3C certification. So, the Civil Aviation Administration's over - reach this time is quite significant, and there are two problems during implementation:

First, foreign tourists' power banks have EU CE certification but no 3C certification. Are they considered inferior products? According to reports from Southern Metropolis Daily and the actual feedback from some bloggers, at least the standards aren't unified.

Second, for products such as DSLR cameras and controller accessories, if the battery doesn't have a 3C logo, it can be taken on the plane when inserted into the device, but not when it's not inserted. This is really quite strange.

Of course, the airports have responded to this issue later. It turns out that the grass - roots staff misunderstood the regulations. Currently, airport customer service in many places says that the new Civil Aviation Administration security inspection regulations only apply to power banks, and the security inspection requirements for camera lithium batteries haven't changed.

However, based on the personal experiences of many netizens, the difficulties in passing security checks for such products objectively exist.

For example, high - speed trains and subways in some cities have also started to check the 3C logo on power banks. During Tony's business trips these days, in City A, they carefully check power banks and even pay attention to power banks with a capacity of over 20,000 mAh, while in City B, there's no such inspection at all.

Some airports also provide temporary storage and mailing services for old power banks without a 3C logo.

Currently, the situations people encounter aren't very consistent, and relevant agencies need to follow up as soon as possible. Otherwise, it will definitely affect people's travel.

However, in the end, the key to fundamentally solving this problem lies in the self
