Following a string of fire incidents involving mobile power banks, the Japanese government has settled on a policy to mandate third-party inspections. In the 5ch thread, users — largely taking for granted that most power banks are Chinese-made — debated the reliability of individual brands like Anker and how much the PSE safety mark actually accomplishes in practice.

Following a string of fire incidents involving mobile power banks, the Japanese government has settled on a policy to drastically strengthen safety regulations. The centerpiece is mandating inspections by third-party organizations, aimed at tightening checks at the manufacturing stage and preventing substandard products from reaching the market. The government plans to announce the policy within the month, targeting implementation within the current fiscal year through revisions to relevant ministerial ordinances.

Guess there really are people out there buying Chinese-made power banks.

And what brand of power bank do YOU use, then?

Power banks are basically all Chinese-made at this point — it's not "Chinese vs. not," it's just good Chinese-made vs. bad Chinese-made.

Not just power banks — I stopped keeping rechargeable lights in my car too.
Don't need that catching fire on me.

Same goes for handheld fans, so don't leave those in there either.

I don't get how people are willing to buy no-name power banks.

Does Anker even count as a real brand?

Wait, there are TWO kinds of PSE marks???

There's a triangle one and a circle one —
one's checked by a third-party body, the other the maker just slaps on itself more or less voluntarily.

The registered inspection body just reviews the manufacturer's self-inspection documents "on paper."
They're technically supposed to inspect the factories too, but that only means confirming the test equipment works — there's no way to actually verify whether the self-inspection was done properly, so they just don't check.
And of course, a PSE mark can still be issued even when the inspection was done by a Chinese registered inspection body.
According to METI (Ministry of Economy, Trade and Industry), this is apparently all perfectly safe and secure lol

They've started selling semi-solid-state power banks recently.

Just go with lithium iron phosphate (LFP) then.

Makes you wonder what actually separates the batteries that last for years from the short-lived ones.
Japanese makers really ought to be advertising this strength more.

My eneloop mobile booster (aka "mobab") — bought it around the time of the 3/11 earthquake — is still going strong.
My Panasonic one died long ago, but the Sanyo-made stuff really holds up.

Honestly, can't we just ban Chinese batteries outright at this point?
>>33
But if you did that, almost no other country even makes power banks, so they'd basically vanish from the market lol

Even Anker used to feel like some sketchy Chinese brand back in the day.

Still sketchy now, honestly.

Anker… more like "Akan-ker" (a pun on "akan," Japanese slang for "no good").

Looked into it — there isn't a single Japanese-made lithium-ion cell left.
Maxell used to make them but gave that up ages ago.
So it really comes down to a choice between the bulky, high-safety type or the compact lithium-ion type.

You mean cylindrical cells vs. LiPo?
I've got one of the Maxell cylindrical ones — 6700mAh, not huge capacity, but plenty unless you're gaming on it.

I used to use an Elecom power bank, but it swelled up within a year and became unusable.
My Anker one wore out before it ever swelled.
I've bought about three Anker batteries and never had one swell up on me —
about the only gripe is the bundled charging cable is total junk and frays almost immediately.

The high-capacity ones do swell up, actually.

Chinese-made products have such an overwhelming market share that of course the fire count would be proportionally higher too.
"Chinese-made = junk" is such a Showa-era mindset.

There are plenty of solid Chinese-made products,
but the problem these days is that the good ones and the junk ones all get thrown together in a "mystery hot pot" and sold side by side on e-commerce sites.
Power banks are basically all Chinese-made anyway —
if every Chinese-made unit were actually solid, we wouldn't be seeing this many fire incidents.

Plenty of these just print the PSE mark on without authorization.
They need to publish a list of certified products online.

That's not quite it — importers are required to obtain a certificate from a registered inspection body.
The inspections themselves are just full of holes.

I've got one too, but the charging speed is slow and the capacity's lacking.

The output is only 1A, so it's usable for something like a "garaho" (a bare-bones Android device styled like an old feature phone), but it struggles with smartphones that have big batteries and high power draw.

These days, virtually every power bank sold in Japan is Made in China (PRC).
So what can you do? At best, you compromise by picking one that's Made in China but managed by a Japanese manufacturer.
I still use a Sony one — even though it's manufactured in China, it's been solid and reliable.

Like I said in >>130, Made-in-Japan power banks are almost nonexistent — you could count them on one hand.
And the few that exist can't compete on price anyway.
So even if you go with Made-in-China, the one line you absolutely must hold firm on is "Produced by a Japanese company."
Just make sure the design and manufacturing aren't entirely Chinese from end to end.

My whole house is full of LiPo, Li-ion, every kind of lithium battery.
These days anything you buy is rechargeable, no matter what it is.

For stuff you rarely use, leaving it sitting around just kills the battery, so it's actually more convenient if it runs on plain disposable batteries —
like old digital cameras used to (some still do).

Products with Chinese-made batteries should just be banned from use in Japan entirely.
