I use mine to charge my Samsung S2 plus my Kindle at the same time & it works just fine.

I used to charge my phnoe with it, but it no longer works, and even new was unable to charge some phone models

yes, the usb ports work fine, it's the center port that is a problem. It's useless and makes the unit extremely large.

The USB ports were able to charge my LG phone but not my GPS. I have to use the center 12v port with an adapter cable to power the GPS. The only downside is the combination of the USB adapter and adapter cable sit pretty far out from the cigarette lighter.

Yes, you can charge USB devices. (My son charges his iPhone.) It doesn't matter that it's not plugged into a computer.

Yes, it can be use to charge just about any portible device. I own one and gives it 5 stars. I love this charger.

I don't think so, it is provided with a regular AC adapter and plug so I would say NO to your question. On the other hand I does have the USB port you mention but it is designed per the instructions to be used to charge phones or other similar devices. This is a great lamp, to be used with regular AC power. I highly recommend it.

No, sorry. This will only charge devices that are USB-powered such as smartphones, electronic book readers, tablets, etc.

Yes, you can. This item has UK plug, and has 1A USB output, it's suitable to charge your smart phone.

Well its cordless so my best guess is yes. It requires a cord/outlet with a USB adapter port to charge it. It has a small cord built in with a USB end on one side. The other side has a cord with a micro-USB end for your smartphone/device plus 2 built in USB ports for charging another smartphone (1.0) and a tablet (2.0). Hope this helps!

The usb port is output power only. It will charge cell phones, mp3 players and other devices that use a usb to charge. So the answer to your question is no.

I don't see why not.... as long as you have it plugged into the usb, but then the USB plugged into the converter to the wall or whatever device you're using to charge.

No, the USB cable is use for data purposes only and is not directly connected to the battery so it can't charge it.

It has 2 USB ports so it should be able to charge anything that can be charged using an USB cable. Have used it to charge phones and gps with the USB ports with no problem.

Yes. Any mobile phone that can be plugged into a standard USB outlet for charging can use this.

No. Probably the biggest thing it can charge is a iPad. How would you even charge a computer. These ports are usb?

Absolutely. The Mini-USB port is only there for charging the device and is not usable for any other purpose. I have used this device with a USB powered external hard drive (you normal everyday external hard drive) several times. It worked without being plugged into my portable power charger (10000 Mil Amp) but worked much better when charging from it.

Not really. It only charge USB devices iPad, phones etc. Computer needs much higher voltage.

Actually there are such things as dc-dc converters in devices.I have 5v mini/micro usb portable charger that uses a single 1.5v battery.So it can be done.I've also read that the xoom has a menu setting that allows charging via the usb lead.Also Mr Partridge needs to learn that mA means milli-amps. So usb 2 can deliver 0.5A or 500mA.Most phones try to suck out 0.8A (800mA) yes, that is why some USB ports can't charge a device as the phone makers are breaking the usb2 spec. USB3 now has a limit of 0.9A thankfully.
