USB Charger or Computer USB Port?

I have a new iPod touch for a friend and an Energizer USB Charger adapter
(PRI 100-240 50/60 Hz 150 mA SEC 5.0V 500mA). The Apple USB Charger output 5.0V at 1000mA.
Is it safe to use the Energizer USB charger? and if in doubt,
is it always safer to plug the ipod or the iphone in the USB port of a computer?
Regards

Alfonso-
Yes to both. I prefer the USB on a computer, but have see no issue with the Energizer, provided it is for the iPod in question.

Nokia 6700 - Charge from Micro USB?

Hi,
The 6700 manual confirms that the phone can be charged from both microUSB and the standard mini charge but what it doesn't say is that the only way to charge using the microUSB port is to connect the phone to a PC or Laptop. If you plug the USB cable into any other type of USB charge device, including USB charge adapters (such as the iPhone charger) or a standard car 12v socket > 5v USB adapter the phone issues an error confirming charge method is not accepted.
I thought the whole point of phone companies agreeing to the new microUSB standard was to permit charging using any USB port? It seems Nokia have limited the charge capabilities of this phone and it is a right pain.
Come on Nokia, please fix this with the next firmware update !!

This is odd, because Nokia lists their AC-10 microUSB mains charger as compatible. I had thought the device rejects any current above the trickle charge from a standard PC USB cord, but if it works with the Nokia microUSB charger, it should accept higher currents (1200mAH). In which case the Nokia charger must be "talking" to the phone over USB to give it approval.
On the other hand, the manual doesn't mention support for USB mains chargers at all, so maybe including the AC-10 on the peripherals list is a goof.
Hopefully this doesn't extend to Nokia's other USB-charging phones, I have plenty of generic USB chargers around.
Help I'm trapped in a sig factory.

My Iphone 3gS is not being recognized in Itunes on my laptop. It is charging so the USB port is working properly. My wifes Iphone IS being recognized by the same laptop. My Iphone IS being recognized by the desktop computer and another laptop

My Iphone is not being recognized in Itunes on my laptop. It is charging, so the USB port is working. My Iphone does work on another Laptop in the house and My wifes Iphone is being recognized on the same laptop that mine is not. Any suggestions?

The key bit of information here is that one iPhone works on the computer in question and another does not. So it is unlikely that AMDS is not running or there is a driver problem; if either of these was the problem neither phone would be recognized in iTunes.
Unfortunately, I don't have an answer either. Except to verify that both iPhones (the one that works and the one that doesn't) use the same cable and the same USB port.
Also, are the two iPhones the same model and same iOS version?

HT1420 How do I get my iphone 4s to load everything onto itunes to do a master reset when it will not allow me to charge it when it is turned on. When I plug the cable into the usb on the computer and the phone at the same time nothing happens.

My phone will not back itself up to icloud because it takes too long and the battery dies before it can complete it . Its been months since it backed itself up and I cant get it to charge when it is plugged in and connected to wifi. I do not want to loose my pictures. This is sooooooo frustrating .

Hello Toniamato,
It sounds like your phone is not charging or charging very slowly. I would use these troubleshooting steps from the following article:
iPhone and iPod touch: Charging the battery
http://support.apple.com/kb/HT1476
If your battery doesn't charge, or if your device shows a low-battery image, black screen, or "accessory not supported" alert, follow these steps.
Inspect the connector at the bottom of the phone:
Make sure that there are no bent pins in the connector.
Make sure that the connector is free from debris.
If there are bent pins or debris, please contact Apple Support.
Otherwise, continue troubleshooting.
Make sure that the outlet you're using works.
Make sure that the Apple USB cable and Apple USB power adapter work.
Plug the device in to power and let it charge for up to 30 minutes. If you don't have an Apple USB power adapter, try connecting to a computer's high-power USB 2.0 port (not a keyboard). The computer must be on.
If the device still exhibits an issue, try turning your device off and then on again while connected to power.
If the issue is persists, please contact Apple Support.
Thank you for using Apple Support Communities.
All the very best,
Sterling

My IPad Retnia does not charge when plugged in using the USB from my computer to car adapter, how can I fix this to be able to have flexibility in charging?

When I plug me IPad into the USB connector to my laptop or into my car charger, it show as not charging. How can I fix this so that I can charge my Pad in these settings?

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
And this - Unplug the charger from the iPad and then replug. May resume charging.
Or - Recalibrate the battery. See link below.
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.

At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Lost the white converter box. Can you plug the USB into a computer to charge the ipad

Can you plug an ipad into the computer USB port to charge it?

You can plug it into a computer but it will be a very very slow charge. The best thing to do is go to any office / electronics store and get a new charger.

You certainly cannot charge the MacBook battery that way, but you could indeed charge the whole computer—to the point it gets totally fried. You may even see sparks and smoke.

That is definitely odd, grantcool. Let's help restore this important data transfer feature. To confirm, when you connect the USB cable to your phone and computer > Pull down the Notification Bar > Select USB Connected > Can you choose Media Sync (MTP) ?

- Try restoring the iPod, first from backup and then try to factory settings/new iPod to rule out a software problem.
- Look at the dock connector on the iPod. Look for abnormalities like bent or corroded contacts, foreign material and broken or cracked plastic.
- Could you have damaged something when you took the iPod apart and replaced the Home button?

Possibly faulty charger. The supplied Apple Charger is covered by the iPhone Warranty. Make Genius reservation or set up service and take or send iPhone and Charger to Apple for resolution.

Can a USB charging port be replaced?

I have a Samsung charge. If I plug in the USB charger, the phone goes blank and freezes. This occurs even if the charger is not connected to power, so I suspect there is a loose connection or unseated port. If I remove the battery and replace, letting it reboot, with charger plugged in, it will show the battery status bar as not charging. I carry 2 extra batteries with me, checked the other 2. Sames issue, so I doubt it is the battery.

If the phone is still under warranty, you should check into the possibility of a warranty replacement. If it's no longer under warranty, it might be worth contacting a cell phone repair shop to see if replacing the charging port is possible. If they can replace it for a reasonable cost, it could solve your problem. Of course, be sure it's a reputable shop.

Why does N97 charge from some USB port and some no...

OK some seem to have same sort of troubles but I couldn't find an answer to this one...
So I have a N97 that charges OK when I plug it in computers USB port or in a (powered) hub.
But I also have a USB power adapter that I can plug in a wall socket and it has one USB port (5V/1A) and nothing happens.
Same happens when I plug it in my car using a USB adapter (not a actual car charger for N97).
Since every other phone/MP3-player/device that can be charged via USB works with these, I have to asume that this is something with my phone...
Has anyone else faced this and have found any solutions?

OK I have some additional info to this one.
I made some experiments with different chargers and cabels and here is the most interesting result (in my oppinion)...
In both cases I used my N97 and the USB power adapter (with 5V/1000mA output).
Only difference was how I connected the two...
By using the data cabel (Nokia CA-101) that came with the phone and nothing it DOES NOT charge the phone.
(and yes it is working cable, since I use it to sync my phone with my PC and it does charge the phone via PCs USB).
By using USB->2mm plug adapter (Nokia CA-100) and the 2mm plug->micro-USB adapter (CA-146C) it DOES charge the phone.
Since CA-100 converts USB to more simple connector then there must be something more happening inside CA-146C than just relaying those wires forward...
Any ideas???

Mac Book Pro Power Adapter with USB charge ports?

Does anyone make a MBP power adapter with 2 USB charge ports? It seems logical to have one power adapter that charge your MBP, iPhone and iPad all at the same time while minimizing the things one would have to carry on travel.

Hopefully!
I said to them "you dont even need to put the ports on the brick itself, put it on that little wall plug adapter thingy... that way if you only want to charge your iOS devices you can leave the brick in the bag!... Fingers crossed and thanks again for the help tjk!
Best,
