Cellular Phone Forum / Manufacturers / Motorola / December 2006Is USB really USB or not (ie does it save a consumer money or not)?
If I switch to all-USB devices, does that save me money & save the world on waste or not? My philosophy is to have the SAME charger for all hand-held electronic devices. That would, in my opinion, cut down on waste by (I guess) billions of tons and costs in billions of dollars over a ten-year period (I'm guessing on the amounts). The way it cuts down on waste is that people can KEEP their old chargers and reuse them on all their devices. After a while, equipment won't even come with a charger because everyone will have so many they'll sell them on Ebay. Old devices could still be used even if the original charger is lost because any USB charger will work (in theory). Likewise with saving on cost. Instead of buying a ridiculously expensive charger for any new device, we could all use our existing chargers and automotive and computer adapters to charge our devices. Since the chargers are all the same (in theory), then they would be cheap due to competitive pressurs (and they'd have more functionality like lights and meters and other nice things). After a while, manufacturers wouldn't even supply a charger with a device because everyone would have had enough. Even safety would be involved as you'd never have a dead cell phone because USB chargers would be standard in automobiles, for example. Having said that I love USB for all these reasons, I find it disconcerting that USB is not USB it seems. Here are four devices and their respective chargers that I own today. DEVICE = Blackberry 8700 SUPPLY = TCPRIM2ULSSN 5.0vdc 750mA DEVICE = Motorola V195 SUPPLY = PSM5037B 5.9vdc 375mA DEVICE = Motorola RAZR SUPPLY = DCH3-05US-0300 5.0vdc 550mA DEVICE = Motorola Earbud SUPPLY = FMP5185B 5.2vdc 450mA It it true that USB is NOT USB? That is, can I "assume" if I hook the Motorola V195's USB power supply (5.9vdc 375mA) to the Blackberry 8700 device, that the Blackberry will be getting more voltage than it 'expected' and that the current delivered will be much less than expected (even more so due to the higher voltage than expected)?

Fraid not. And USB wont deliver 750mA anyway. >>Even safety would be involved as you'd never have a dead cell phone >>because USB chargers would be standard in automobiles, for example. > > You wont be charging cars with USB chargers any decade soon.

You f.cked up to keep with words you understand and thought she meant to run a vehicle off a 500mA supply ;) Enjoy the new year and lighten up. > If I switch to all-USB devices, does that save me money & save the world on > waste or not? It's wasteful if you're replacing functioning equipment just for the sake of getting that USB connection. A better strategy would be to migrate to USB-compatible devices only when you have a real reason to upgrade the equipment. Who knows how long the ubiquitous USB connector will be around? The only thing that is certain is that something else will replace it.

Doubt that is going to be any time soon. If you work on that basis, you wouldnt buy anything, ever. > If I switch to all-USB devices, does that save me money & save the world on > waste or not? [quoted text clipped - 40 lines] > > Emily Dear Emily, The USB standard refers to the computer end. You can use a USB powered device on USB ports from different computers. The actual wall charger made for a particular device may or may not be designed to mimic the exact USB standard. Since a manufacturer is designing a matched combination they may use a little higher voltage to get the device to charge faster from the wall. Since they designed the device and the charger they have figured all this out. On the other hand another manufacturer may build a device that will not tolerate a higher voltage. Both of these devices will work fine connected to a computer USB port but may not work properly when connected to different chargers. Hope this helps. > Dear Emily, > The USB standard refers to the computer end.

I would be VERY interested to hear if somebody harmed a device by plugging it in via USB to a charger from another brand, or even if it failed to charge (unless it was an "unpowered" port). I doubt a device capable of doing damage could be licensed as "USB" in the first place. It's well known that not all USB ports can supply the same amount of current, and all the chargers listed are within a volt of each other. That's nothing to worry about in my book; any normal battery will vary by more than that over its lifetime. Personally I love USB; my GPS, camera, mp3 player, and PDA all connect with the same cable and it really reduces clutter. I have never found incompatibilities to be a problem and I wouldn't hesitate to charge any USB device with anything that offers a powered USB port. > Here are four devices and their respective chargers that I own today. > [quoted text clipped - 10 lines] > delivered will be much less than expected (even more so due to the higher > voltage than expected)? Normally I don't reply to cross-posters, but I feel your intent is well meaning. I asked similar questions of an EE a month ago. His reply was a 'qualified yes, but'. If the devices were designed properly, the lower powered devices should only take what they need from a higher powered charger. Note the words 'properly' and 'should'. On a trip, I jacked a 450mA GPS into a 850mA auto charger. Once turned off, the Bluetooth of the GPS would not turn on until the battery was removed, all contacts cleaned. This was the 2nd day of usage for the new device. It resumed working until I charged it again. It died for three weeks while the factory replied it was a dealer problem. During the 3 weeks I tried to get a response from the eBay dealer, I 'cycle charged' the GPS several times with the GPS charger. It started working again. I won't be mixing chargers again. If the value of a standard charger for everything is worth frying your devices and chargers, start experimenting. If you are successful, you'll reduce the number of parts the manufacturers will have to provide, but probably not the price. By the way, if you multiply the power used by all the transmissions of the Internet providers, communications companies, cooling equipment for same, modems, routers, and PCs, the total power consumed via nuclear, hydro, fossil fuel, etc. >never to be replaced< just to answer your long posting and multiple news sites, probably will never be off set by the savings in the power of your chargers. Emily The chargers are not USB.. a USB device is USB by virtue of the way that it connects to the host computer, not to the power supply unit.. > If I switch to all-USB devices, does that save me money & save the world > on [quoted text clipped - 44 lines] > > Emily USB is not only for charging!!! USB stands for Univeral Serial Bus and is a method of allow a PC to communicate (aka talk) to devices. It simplfies the method of connecting devices to your PC. Do not only replace devices because of the charging method. > If I switch to all-USB devices, does that save me money & save the world on > waste or not? [quoted text clipped - 40 lines] > > Emily > USB is not only for charging!!! Wrong, plenty of the small stuff like mp3 players charge using that.

Its more than just that. > Do not only replace devices because of the charging method. Makes a lot of sense in some situations, most obviously if you are moving around a lot and want to have just one charger etc. >> If I switch to all-USB devices, does that save me money & save the >> world on waste or not?

It is indeed more than just that, its also commonly used for charging the lower power devices like mp3 players and ipods, and for powering all sorts of low power devices as well.

Yep, heaps of them, and heaps more that just use it for power and not for data at all. Most commonly used with laptops, but quite a few now intended for desktops as well. > "Rod Speed" <rod.speed.aaa@gmail.com> wrote in news:4vns7cF1d05b4U1 > @mid.individual.net: [quoted text clipped - 16 lines] > So there are devices with a USB conection for charging and do not > communicate to anything over said USB ? Yes I have a fan unit for my laptop that plugs into the USB port to power the 2 fans. Windows doesn't even know its there.

Windows > doesn't even know its there. Yeah, thats what I meant. Plenty of LED lights etc too. Quite a few of the lower power devices like mp3 players use USB for charging, so you dont have to far around with a separate charger for them. Much easier to charge them that way, you dont have to hunt up a charger and rather frugal since you dont need to supply one in the first place. |
