- In a world powered by rechargeable batteries, power banks have become an integral part of our lives. But these devices have also captured worldwide attention due to their tendency to suddenly combust.
In Singapore, 54 fires caused by power banks were recorded between 2013 and 2023. Using safety tests and fire simulations, Steven Chia investigates why these portable battery chargers can turn into ticking time bombs, and how to make sure the ones we buy are relatively safe.

Hi CNA can you send hawker centres' food trays samples to check how clean they are? Many food trays are simply given a wipe down and reused.
Agreed! It is getting worse nowadays. Sometimes I just give up the dirty tray.
@@aceleecy I treat trays as common surfaces like tables. Try to wash your hands after handle tray with food before eating or dont use hands to touch food it touch trays. Even utensils and bowls have questionable cleanliness with leftover food...but no choice need to overlook that if not no need to eat anymore
@@ashleykeelivoon questions like these are why outsiders consider SIngapore a nanny state! LOL. Do you lick your trays???
@@daphneg5712 maybe they put food directly on the trays sans plates and bowls? 😁
Have you met the KOPITIAM of North Point Trays before? They are scary! But you won't find them now as KOPITIAM had sold to Foodfare and it seems their practice is getting better but of course, if you really check, they are still gross.
Hi, I am from Germany. I just want to praise the high quality of CNA Insider videos! This channel has become one of my favourites and I love especially these very interesting Talking Point episodes! I used to be very careless with powerbanks, because they seem so sturdy. Your video was like a warning-/wake-up-call. Great content, great topic, and very good video cutting! Keep up your good work! Liebe Grüße aus Hamburg!
Important to note that all lithium will burn on nail penetration test, the energy has to go somewhere. The purpose of nail penetration test is to see how the battery actively contain the burning.
LFP and LTO don't seem to suffer this tendency to self-immolate.
8:12 That purple powerbank that says its 20000mAh... The blue batteries are what we call 18650 battery cells and they're about 2300mAh. How can this powerbank have 20000mAh on just 3 of these?!?!
The people selling that powerbank just lie about the capacity so that it looks more appealing to the general consumer
The manufacturer lies about the capacity. These lying powerbanks are all over Tiktok Shop being promoted to hell and back by clueless 'influencers'
Thanks a lot for this information! Keep up the good work.
Thank you for this content
I recognize the packaging from local brand! It's Energea! Not as expensive as popular brands such as Anker but works really well!
For most power bank with flat surfaces, there's an easy way to check for bloating; try spinning it gently. If it stops immediately within 1-2 turns, it's not bloated. If it still spins easily after a few seconds, then you have a bloated power bank.
That's a red flag. They need to be disposed of immediately and we should not use them. Bloated chargers are safety hazards
Thank you!
It's time people stop buying cheapo powerbanks. It may be cheap now but may not be cheap in the long run if you have to keep replacing it.
Using only Anker brand power banks for couple of years now , so far the best for me.
Same. Anker only.
Same here.
I remember when i was in China ready to board a plane during the security check , the custom officer ask every passenger to bring out the powerbank if they carry any, they check every powerbank thoroughly , some of unpassed powerbank was throw inside the bin, they were check for safety mark, these stringent check never happen in Singapore airport
The confined space for the testing looks bigger than the hotel room I commonly stay in Singapore during my holidays. Wew.
Can you share the links to the battery packs?
Could you test out the Nitecore video light with 10,000 mh power bank? I seen one review saying the light came on in their camera bag and it got really hot.
"It's dangerous when overcharging...." such misinformation to public. People will assume you keep charging so it becomes overcharged which isn't the case practically. The experiment tested on upping the voltage charged which do not happen in real life unless they have a crappy BMS circuit or the BMS faults. The BMS circuit cuts off charging and usage to the battery when it hits certain voltage on the upper and lower mark. The crux of the issue is crappy BMS. Also there's heat issue and bad batteries.
Finally someone who understand a powerbank is not just a bunch of batteries, it has a circuit board that monitors voltage and protects the battery. The circuit board quality varies with the brand. It's OK to buy branded Chinese battery like Xiaomi, those no brand ones are risky ... usually the problem is they overclaim the capacity like 50,000 mAmp is just 2,500 :-)
Not to mention they avoided testing that 'branded' powerbank with the same overvoltage test with explosive results. Probably they will show that it might end up having the same issue whether it's branded or not when it's not charging according to manufacturer's specifications
Great work informative in this IT age
Brilliant video
I only use Aukey products because the company was founded in Germany and has now relocated to Shenzhen. They produce quality products that are safety certified.
Common li polymer cells are not 3.2v as the guy in the video was quoting. 3.2v cells are the BYD type lithium iron. Lipoly cells are 3.7v to 3.9v, the FPV guys knows this well.
I don't use powerbanks because I don't like to carry heavy stuff in my pocket I just uninstall all the bloatware and turn off all the useless bells and whistles on my phone battery can last more than a day already. They should do a next segment on cellphones I remember cellphones also blew up on planes before.
One thing I learn is don’t fast charge your power banks. Use an appropriate voltage. Most common being a 3V. Charge your power bank in shaded or cool areas. Set up a alarm for when you shut the power or use smart plugs with timers even though modern power banks are designed to accept a trickle charge when the capacity approaches 90%.
Does installing of RCCB circuit in the house helps to cut off supply if the battery overcharge and unattended?
No that is up to the BMS circuit inside the powerbank
remember the pmd in the lift . gahment takes it too lightly
SG gahment should insist on all powerbank imported to SG with UL (US underwriter lab tested).😅
There might be a misinformation which might lead to misperception in this video. Have you investigated in which country the powerbank was made before showing "powerbank from Taiwan" at 0:32 in the video? Maybe "incident from Taiwan" is a more appropriate description.
Most importantly get a certified powerbanks... there are not too expensive ones. Batteries are something you dont want to cheap out on. Other less crucial things can go crazy and save money
Where can we get our Power bank to for test ??
I bought a power bank in 2014 for $55 & until now it's still working.
Wow, that's insane, unbelievable. 😮
Dang your an old og
now... it has less capacity...
The question is "Is it still safe for use?"
@@Dominus_Potatuswhy not if it still works. But over time it will fail to hold any useful charge just like laptop batteries.
Bought two Anker batteries 7 and 10 years ago (PowerCore 10000 and Astro E4 13000), and a INIU battery 4 years ago. All still working great.
I think one of the most important thing for airplanes is to have usb-a for charging your devices. Power banks must be registered and tested for explosion testing.
I don't use powerbanks anymore.
I use a tablet that gives me enough juice all day.
Many coffee shops and restaurants supply power for customers anyway.
I gave my old powerbanks to a local university for safe disposal
If phones companies can make good batteries that last and last.... Then we don't need to worry about powe banks
Yeah got a 13000mah battery phone love it
The technology catch up faster than battery hence battery technology is lagging behind. Phone companies introduce super fast charging to overcome this problem. Xiaomi with 120w charging can charge 100% within 15-20mins I think
5:18 Case stress test
6:08 Overcharging powerbank test
9:18 Drop test
14:40 Overcharging powerbank test (Explode)
These are only little flies compared to the battery of an electric bike..imagine the dangers of those batteries!
This is one of the reasons why to buy powerbank enclosure than the irreplaceable one.
producer looks legit with them nails!
caught that guy throwing that single luggage tsktsk
In short. If it looks dodgy don’t buy. Only buy well known brands. If the brand of powerbank is also available on Amazon then it’s good but do in depth research too. Personally my picks would be Anker, Ugreen, Baseus and Xiaomi
May I ask here, I heard buzzing sound from my power bank while charging it. It is already 2-3years and only recently it is like this while charging. Brand is Pineng. Is it still safe to use/charge? I have completely stopped using it until someone could answer it…
Mine has a light buzzing sound when connected to my phone to charge. I would like to know too.
Normally, it's fine, does the buzzing sound comes from your charger head or the power bank? So long as, your power-bank doesn't feel very hot to touch and it doesn't puff up, it should be fine.
This could be down to a phenomenon known as 'coil whine':
en.m.wikipedia.org/wiki/Electromagnetically_induced_acoustic_noise
While not neccessarily a cause for concern, it's always good to keep a close eye on your powerbank - make sure it's not overheating or bloated.
Might be coil wine it’s common in electronics
Thank you everyone for replying. The buzzing sound comes from the power bank, and extremly concerned until I have ditched it aside for few months until I watched this episode of Talking Point.
Bloated should be a straight fail. It is a strong fire hazard..
😂same As BYD cars everytime caught Fire too😅😅
LiFePO4 cells are orders of magnitude safer than Li Ion. Just use LiFePO4 cells in power banks. An added advantage for the LiFePO4 cells is cycle life of >3X that of Li Ion.
Short and concise answer : any China brand power bank is a time bomb
CNA the max that can bring on plane is 100Wh not just 27k mAh.
Some battery is 7.2v some like laptops have 14.8v. So with higher voltage, the mAh is lower
To specify the maximum limit for a power bank or battery pack as specified by the IATA (International Air Transport Association) is 27k mAh or 100W, regardless of whichever one comes first. Some commercial airline may offer a bit more leeway however if you are carrying a power bank or battery pack that exceeds such specification then you may always try asking the airline for special approval prior to boarding the plane.
I have a solar power bank. I'm not sure how it's made or works. Mine works and charges good for a solar bank. Says it can charge tablets and laptops to. But wondering if there's any kind of risks with those.
Tell us more about your solar powerbank!
13:47 i had a lithium polymer battery accidentally punctured and it immediately exploded 🔥
Does this mean that we can still use budget, unverified powerbanks, even if you've been vaccinated? Were any of those burning powerbanks Russian? Can you take a large power bank on a flight, if it's covered by a mask?
Can you taste a rainbow? What sound does one hand clapping make? Do I have to go to the mountain or will the mountain come to me. So many questions. Very few answers.
27000 mAh limit? So... technically I can bring 7.2V?
I think FAA's limit of 99.99 Wh is making more sense
9 incidents, 5 was from powerbank
I wonder what phone explodes in the plane
I use Anker power banks its the safest been using for 7 years straight so far its durable and good for phones too around 100+
Failing tests, vendors get fined
This is the reason why the army needs to bring back plugs.
I heard they don't allow NSFs to charge via the wall outlets in camp?
@@dankrakes4648 After bmt we can charge via the wall outlets
That is why these devices are forbiden here in my country..
What country please?
My brother said he was interviewed about power banks, he isn't here
I got a bloated power bank before...A pack of sand like materials was inside to my surprise...That was from China many years ago....
Hi
Im curious as to why the 'branded' powerbank was not subjected to similiar test towards the 2nd half of the video? An unbranded powerbank would be expected to such failures but then why don't u do the same for the branded ones as well??? That would be a correct direct and accurate presentation. Otherwise it seems a very 1 sided affair.
Opens them up to lawsuits
I would suggestion do check the input stated at the powerbank e.g 2A and 5V. So make sure the plug you does not exceed.
Recommend to used additional protection e.g RCD Plug it can save you e.g from electrical shock or it cut off the supplied before it happens, e.g you can look for 10ma plug
With a good quailty cable and charger, your good quality power bank can talk to the charger to have the correct voltage and ampere.
This is biased. Why didn't you test the branded ones for overcharging and short circuit?
You can find the segment on short circuit testing for all 3 powerbanks at 5:56
Slightly further along, you will find the segment on overcharge testing at 6:11
70C = 158 F :) if someone is wondering and too lazy look it up.. You are welcome :)
most hdb fires are caused by PMD and e-bikes batteries, that should be covered instead, not portable chargers. 1/10.
Runway. 😆
Oh No!
Who builds the better battery
Will the world beat a path
To his door, though it be
Out in the boondocks?
😏😏😏😏😏😏😏😏
Racism!!! Only the German guy got subtitled!!! :D
😂 if EV cars hit a sharp lamp poles, = bye bye to yr,EV cars when crash= fire😅😅😅 buy 1 destroy 1 free❤
Alkaline batteries are the future. It cost less and is not combustible.
japan will retake the kurils sakhalin and vladivostok south korea will take north korea.
Thanks for this vid🫡💯
Its disingenuous to show 0:40 a electric scooter fire when you entire episode is about power banks
Based
Only Anker or Belkin are safe powerbanks I recommend! I’m currently using 20,000 powerbank from Belkin.
The charger from them 37w doesn't even get warm. I'm impressed
Powerbanks explodes cause they are made by china.😂
