Seems like good value for a 3 port charger with decent power output. I picked one up in store yesterday. Well designed and well made.
From their website:
3 USB ports
Equipped with auto-detect function ‒ the USB charger detects the connected device and adjusts the power output accordingly
Total output of 3.4A, 17W
Maximum output per USB port: 2.4A
Comes with built-in over-current protection, short-circuit protection and over-heating protection
Neither is $10.
You don't generally need to fast-charge more than one phone at a time. I personally use a single cable for my phone and leave 2 more cables plugged in for charging my headphones and smartwatch, which don't need much charging current at all.
If you need more charging current, by all means find a different charger that's capable of doing what you need. But it will almost certainly be more expensive and/or have fewer ports.
I would not grab this slow charger, no QC or PD
I rather have a charger without quickcharge, my phone has not option to disable QC & I find it shortens battery life.
That's one of the biggest myths.
Hi Clear
I have to ask, if it is a myth as you believe why does Apple slow down charging on the iBone?
I agree with you and don't think it's a myth at all. Faster charging generates more heat and heat certainly can degrade lithium batteries. I turn off fast charging on my phone for this reason and also limit my charge to 85%.
There are objective report about impact of fast charge to battery life. The difference is less than 1% over 1 or 2 years. Definitely not significant if any.
@BargainHunterMYz: I believe this is now more of a factor with the latest ultra fast charging, mind.
You probably keep your phones for 10 years? With the majority changing a phone at least every 3 years, the minute effect that QC may have, will not be relevant
You are right, but also wrong.
Fast charging no, Super fast charging not really.
There is a bit more heat but it is not really relevant, have a look at some of the charger reviews for PD 25w fast charging and PD 45w super fast charging of the S22 Ultra.
I think people assume it charges at 25w or 45w the whole time.
@mitt Slow charging overnight etc is the worst think you can do for Lithium battery's.
Frequent fast charges (25w) is the best for extending battery life.
I have an option to time a charge so it finishes just as my alarm goes off so it's not sitting at 100% all night.
I just wish it also had the option to turn fast charge on/off. For some reason Motorola decided to remove an option thats standard in android.
But it is "Equipped with auto-detect function ‒ the USB charger detects the connected device and adjusts the power output accordingly"
Some serious technology there!! Surely that implies some smart voltage negotiation, and they are not just making up bullshit?
and they are not just making up bullshit?
IKEA have no idea, they just say what their seller told them. I'm an electronics engineer, and it sounds like 100% marketing spiel to me.
It's like saying that your car's suspension adapts to increased weight as passengers get into the car. It's true, but it sounds far less impressive if you say "the springs compress a tiny bit more as you get into the car".
I don’t think it’s BS. I think too much is being read into what they are saying. I think it means they are just current balancing between connected devices. ie if only one is connected, that port gets its max 2.4A otherwise 1.7A across 2 ports and 1.1 across all 3 when fully populated.
they are just current balancing between connected devices
This is a misunderstanding of how USB supplies work. On a 5V USB supply, it's not possible to "current balance" between loads. If a plugged-in device draws 2.4A, the power supply can't do anything to reduce that current, other than turning off that port entirely. The power supply can't lower the voltage, the USB spec says it must be 5V+/-0.25V.
"Balancing loads" is marketing speak, it's not a real thing on a fixed 5V supply.
If you pull this power supply apart, I can almost guarantee all three USB ports are connected in parallel. There is no way to sense an individual load, and no way to vary an individual load.
If a plugged-in device draws 2.4A, the power supply can't do anything to reduce that current
It doesn't really work like that. USB charging is far more complicated than just plugging a load into a supply. A phone capable of charging at 5v 2a doesn't just blow up an old 1a phone charger.
The power supply can't lower the voltage, the USB spec says it must be 5V+/-0.25V.
i believe when you are talking about dedicated chargers they can lower the voltage if current goes too high, they are treated differently to regular communication USB ports. The charging circuit on the device should detect this. Either way, the voltage can also go way higher now also if the appropriate fast charge or power delivery is negotiated between charger and device.
The Ikea charger could be telling the connected devices different max rates depending on what else is connected. Would be interesting to check with those cables that show how much current is going to a device. If you connect 3 2 amp capable devices does it tell the 2 and 3 to charge slower or does it renegotiate max charge rates? no idea.
@Duff5000: Have a look at the pics of the circuit board, in the review linked below by @nandystam.
From the review: "Running all port in parallel I found out the common protection trips just above 4A."
A phone capable of charging at 5v 2a doesn't just blow up an old 1a phone charger.
Any phone that draws more than the USB2 maximum current of 500mA, will first check for the presence of resistors connected to the USB port's data pins. If these resistors are present, the resistor values indicate how much current the USB port can supply, and the phone then tells it's charger chip how much current to draw. It's not the power supply that limits the current, it's the phone.
From the review: "Port ports has automatic coding up to Apple 2.5A"
But the review also had no difficulty drawing 4A from those ports. The current limiting is not done by the charger.
The only limit this charger appears to have is overload: "Running all port in parallel I found out the common protection trips just above 4A." The "NTC2" component on the PCB, connected to pin 2 of the SMPS controller chip, suggests this is an over-temperature protection, not a current-sensing protection.

I hadn't seen that. Wow

When i read your other reply i thought you were suggesting that step didn't happen. No worries, i get what you were meaning.
These are convenient, been using last few years, thanks will grab another
Has anyone noticed that IKEA has jacked up their prices on many products by atleast 40-60% ?
Inflation.
How much was it before?
Ïnfŀååtȉȫn
It’s not Inflation, it’s infatuation for bigger profits!
Yep. The sofa I bought from Ikea a few years ago is now about $400 more expensive on their website.
The quality of wood and thickness has also dropped. My older furniture is way better than the things they have on display now.
Shrink-flation, IKEA style.
Pity it didn't have the passthrough to not lose a power socket. Great design for running the cables up to the bedside table.
And depends what is in another socket - their wide design restrict what else you can plugin
Thanks.
Great price but I need USB C as well personally.
TLDR: "It looks like a very clean design, no parts on top of each other or squeezed together, there is space for everything, including a good isolation distance. The performance is good."
Be aware, this output detection business can result in some items not being fed the power they should be, reliably.
this output detection business
It has none of that, it's marketing BS. The review that @nandystam linked has good photos of the PCB, and the power pins of all three USB ports are connected together. So there's no way to detect how much power any port is drawing, and no way to disconnect any port.
How long will it take for this to charge a Tesla?
Asking for a friend.
4 to 5 years.
I think the wait time on new Teslas is less than that, so might as well just order a new one every week, then drive them until they're flat and the next one arrives.
These are pretty good, I've got a few.. but I'm currently moving over to USB-C quick charging, so good.
If not worth using it as phone charger but at least good for powering multiple LED strips i guess?
I wouldn't leave this continuously powering something, unlikely it's designed for that. Some electronic components (e.g. electrolytic capacitors) have a lifetime as little as 1000 hours (42 days!) when running at their maximum rated temperature, which you could achieve by plugging in a load that doesn't drop, like lighting.
Power supplies designed for a continuous load have better-quality components with better ratings, and are designed to keep the electronics cooler. Unlikely you'll find such parts in a cut-price power supply.
wonder if it would be good enough for kids usb nite-lights
No reason i can see it wouldn't be. That said most of us have several 5-10w (1a-2a) USB plugs from old phones that should be fine as well.
A night light is going to be well under 5w.
says not available for delivery for me
Bear in mind you can get this for free if you get a $10 voucher from joining ikea family
Link broken now, hopefully they’re still in store
Can confirm this is still available in store
Nice, which one did you see it at?
Tempe had heaps during the weekend
3.4 over 3 ports isn't much
