Just make it 19v normal small round type used already by most.
Dell and a few other should shove their weird chargers.
Great idea, considering in the past a lot of manufacturers would change the connector with every new iteration of a laptop...
A universal charger for laptops can't come soon enough imho. Here's hoping that someone doesn't manage to derail it, either by patent trolling or by not-invented-here.
And how come everyone of these "universal" laptop chargers that I've ever bought from PC World etc have had the most awful whistle on them when I've used them? Am I just very unlucky or are these just a load of ...
Oh, and while I'm on the subject of chargers, someone really needs to go around to Samsung and smite them most strongly around the head. I cannot see any justification why you have to use their 2A USB charger for things like the Note 10.1 because all others are blocked (they've done something funny with the socket so it can tell if you've got one of their chargers or not)
Career status: still enjoying my new career in DevOps, but it's keeping me busy...
If they could also make it so the charger can fit into a defined small area, so that all laptop bags could carry the charger that would be great. Too often have I had a bulky power brick jutting out of the side/top of a laptop bag.
Apple's chargers are good - less chunky cable, built-in spool, small compact shape.
About time TBH! But I hope they do a good job of designing the spec, some common designs are needlessly fragile.
Unfortunately there are an *awful* lot of dangerously poor quality adapters/chargers out there, even some being sold as 'genuine' on sites like Amazon and eBay, and it can be hard to tell the difference from the outside. It would be great if a few reputable companies would release things like this universal adapter, and things like USB power supplies, with an easy way to check their validity, and have more effort put into removing the dangerous counterfeit models from the market.
The above could lead into why Samsung limit what 2A chargers can be used - some cheap chargers bodge the spec by shorting the data pins (which basically tells the device to draw as much as it wants) but then can't safely provide enough current. I'm not arguing one way or another about that choice, but I can understand why they might have made it.
The only issue with this is current draw - they'd be able to standardise for the majority of laptops with something like a compact 75w adaptor, but that doesn't cover the beefy desktop replacement units at 95W+. It would also be needlessly bulky for low power machines like ultra portables that only need 15-20W or so. So, 'universal' with different grades: low, medium and high power - would work, but perhaps defeats the purpose.
This is wonderful news, and this should have came years ago.
Only thing is that they're not going to be able to just introduce a single charger, there would need to be two or three different power ratings to allow for the difference between large gaming laptops and smaller entry level ones. No one needs a huge 90W brick for a little 15" laptop.
Thing is, provided the connector is standard, the power shouldn't be too much of a problem.
I had a Dell laptop a few years ago, a Studio version with a reasonably powerful dual-core processor. I took it into school on occasion, and sometimes borrowed the school's laptop chargers if there was one kicking about. They were also Dell chargers of the same generation, but not as high power as my charger from home.
If I plugged it in, it worked fine, and I just got a warning message that said "This power supply can provide 65W, but your laptop should be used with a 95W power supply." It still kept my laptop going, but had I been running Furmark with the screen on full brightness then I wouldn't have been surprised if it had struggled to increase the level of charge.
In short: as long as the connector is standard, and someone puts a bit of thought into how the power is delivered to higher/lower spec machines, I don't think it would necessarily be too big a problem.
As above, as long as it's well thought out, power shouldn't be too big a deal.
It's not that different to USB power supplies now - it's part of the spec to negotiate/sense power requirements. Some devices might come supplied with a 2+A supply, but you can generally still charge them, albeit more slowly, on a compliant 500mA adapter.
Another great idea that apple will ignore
For me the tape keeps getting bigger
I do have a belkin universal which is nice and thin, of course you need to swap connections but the fittings are nice and solid.
As others have said this really does make a lot of sense, as with my universal one its capable of powering many laptops, so if they all had the same connection it would be a little less fuss.
i love how it worked out with mobile phones, pretty much never have to worry about having my charger with me, as pretty much every decent company has accepted the new design no longer will you have a "crap my phone is flat anyone got a "insert phone brand here".....no not that one the little one XD, oh well pretty much all....except apple the company that loves forcing people to pay a premium for everything apple branded
unfortunately i see this happening to a worse degree with laptop chargers, DELL, HP, COMPAQ and a few others have spent time and money ensuring you are forced to buy their own branded chargers or they disable the ability to charge the battery.....yeah you can use a third party charger but "YOU CAN NOT CHARGE THE BATTERY" there's too much money in it for them to just accept an agreement that would help their customers, unless there is something in it for them, same as with printers and the monopoly of how and where you can buy ink
Re: The Samsung chargers - it's because of cheap knock-off ones they've implemented this....look on youtube and there are scores of videos of them crashing and burning...
Apple, of course, have something similar...I await them sueing Samsung in due course
Old puter - still good enuff till I save some pennies!
Isn't USB 3.1 supposed to be able to supply up to 100W? There's your universal standard right there - and it's also an extra USB 3.1 port on the laptop.
It's only really larger desktop replacement laptops that would draw more, and you could always double up much like you used to do with USB HDD.
