Could this be used just to charge USB devices like smartphones and portable music players? I would like to just have it plugged in an outlet. No comp

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

It will provide power without being connected to a PC and can charge some items, however devices that require higher current to properly charge (tablets, etc) might be a problem.

Most USB 2.0 hubs will recharge devices, except tablets. USB 3.0 has even more capability (900 ma vs 500 ma), but still not enough for tablets. Also, be careful not to exceed the combined capacity of the power adapter. Multiple low current devices should be okay, but limit the number of phones and devices that are more power power hungry to two at a time.

No, it is really for low power items and charging things like cell phone, ipods, ipads, computers.

No. That requires other hardware. This is strictly for charging your mobile device.

If there is, it's by no means accessible to the average consumer. The clear answer is no. You can charge this through its micro usb port and then have it ready to power an electronic off the (full-size) usb slot when needed on the go. If it dies, you get a new one. If that's a concern then get a better, more expensive one.

Yep as long as the plugs don't take up too much space. I have personally had two USB devices, a blender, and a laptop in this outlet. I have also charged two iPads charging at the same time from it

Unfortunately, I wouldn't recommend buying it. I used it on one trip to Italy and it couldn't supply enough reliable power to run a portable DVD player and a cell phone at the same time. The outer casing on the AC adapter I had plugged into it actually started to melt ! It would only do that if the frequency or voltage became way out of specification. If you read some of the reviews, other people had similar problems with it. I would only use it as a convenient USB source to charge your cell phone.

Yes, it works like an extension cord for your USB devices. I have charged my Kindle, iPad, iPhone and other Android phones with no problem.

No. USB is for charging purposes only (2.1 amps). More info: http://m.tdkperformance.com/en-us/Home-Audio/Boomboxes/Wireless-Sound-Cube/

Hello Kirpal, From your question it sounds like you want to use it to power a computer. The answer would then be no. This is for powering devices that only use a small amount of power. Make sure that the voltage and current requirements for any device match the output of the adapter. Also, I would not use it to charge or power any devices that are very expensive because there are protective devices in more expensive power supplies that are absent here. Hope this helps.

You can play music when you plug in the micro usb, but it neither charge the battery nor use the battery it will worked like you take out the battery of your laptop and plug in your charger. It could work, but it won't charge any power

It accepts a USB charger, so it should work. I use it for mp3 players I have, of which one is a Apple Nano, a shuffle and an iTouch. hope that helps. I like this one, because it is built sturdy and it has a swivel feature, so you can plug it in upside down if you have another cord in the same outlet

I'm actually using a spare one for that function now. HOWEVER, it will only charge items at the USB limit of 500mA per port. Most true chargers are capable of 700mA to 1000mA depending on the device.

Yes, I use it to charge my Android and other devices with the USB power cord. It's so simple to use and easy to carry in a backpack or purse. Go for it!

We tried, but it doesn't. It's for audio only, but don't let that discourage you! Are grading what Joel said, it may be only a 1 amp charger--able to charge smaller devices and not larger, such as tablets, etc.

No, it can not be used to charge other devices. It has a USB "in" (micro) connection that is only used to charge the speaker itself.

I only use it with external power, but I believe I recall reading that it can not be powered by USB.

It charges itself by a mini USB and charges other devices the same way. You might be able to find an adaptor if you need something else. I have not been impressed by its capacity.
