[DailyTech] USB 3.0 Group Proposes Eliminating Proprietary Laptop Chargers - Page 4

This sounds really swell. redface.gif

I don't care if they do use proprietary charges, but can we just not have them sticking out 2 inches from the sides of the laptops? I have needed to replace two different laptops due to the internal connections breaking from the stress placed on the cantilevered plugs.

If it's a battery, can't it charge with a small amount of power anyway? Wouldn't lower power mean it just charges more slowly?

A more logical solution would be introducing a better standard for universal laptop power cables, but it is highly unlikely that this will come to pass as laptop PSUs are actually fairly decent money makers for most companies. You can see as much by checking how much a replacement laptop charger costs on eBay versus directly through the distributor.

And, besides that, it does not even deal with the simple fact that being able to plug any charger into any laptop will lead to people plugging in chargers that WILL damage the system. So, another set of devices to add, or attempt to force everyone to use the same voltage.

My MSI laptop uses 240w power supply so yeah. That would be very problematic. And i dont actually have a problem with a brick like this, anyway.

The laptop I'm on right now uses a 180 watt brick. Sager NP9150. But I like the idea.

Awesome idea. Don't see why they should have to change the standard for a small minority of laptops that draw over 100W. Let those keep a proprietary cable. I would love to have a charger that fits both laptops at my house.

I actually wouldn't want this, at least on my laptop. I would have broken my Macbook a long time ago if it wern't for the magnetic power cable.

If it's a battery, can't it charge with a small amount of power anyway? Wouldn't lower power mean it just charges more slowly?

It wouldn't charge at all, just drain its battery slower. My SGSII sometimes uses more power than the charger gives it and that's what happens to it; you'd need to either keep it idling below 100w to charge or have it turned off, otherwise you'll still drain the battery.

I hope this happens, it would be harder to break the USB port it's fairly rugged for a port and people would be much happier not having the jacks fail. However, lots of power running through it I'd guess board would fail left and right.

MicroUSB isn't, I've had about 3 cables break on me already. (For my external USB3 HDD)
