No. It is more of a backup for making phone calls, etc. when your phone's battery is low.

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

Haven't tried it on a laptop only on iPod, iPad & cell which worked very well.

No, this does not have enough amps. You have to look at how many amps your laptop takes and buy accordingly. For instance, this does well for most phones and tablets, but not the IPad 2 because it has too low of amperage.

You can use the supplied USB cable to connect it to your computer to charge. Once charged it lasts for ages

Just be aware it can't charge laptops the current only goes one way. It comes IN from the USB plugged into a laptop with the micro USB plugged into the side of the charger and it goes OUT the USB port on the end of the charger top the micro USB at the end of the charger. I saw someone complain the charger didn't charger their daughter's laptop and instead was draining power...

Yes, that is how I charge mine. It comes with a short USB that you plug into your computer to charge and transfer files.

It pretty much charges anything that plugs in via USB. I don't know how many charges you'll get on the laptop before having to recharge the unit, but sure...it would work for that too.

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

Gisela, no this device does not charge your laptop, you will still need to use your computers power supply. It does have a lot of extra USB plug to charge other devices. Yes you have to open the laptop to turn on. It does have two monitor plugs and I correctly use both with the laptop closed.

No - it has a 12VDC digarette lighter output...you could get an inverter (about $20) to plug into that and power your laptop, though.

Any micro USB to USB cable can be used. Charge it from a USB port on your laptop or desktop.

You can charge it both ways. It comes with an usb charger for the computer but if you get an adapter you can charge through an outlet.

Sorry for late, I don't think so that it can charge laptops. The bag just 3 mobile interfaces and plus a USB interface.

Unfortunately that's really not how it works. In order to charge any laptop, netbook, etc. you need to connect to its power input port. What you are looking for is something like this: http://www.amazon.com/Energizer-XP18000-Universal-External-Netbooks/dp/B002K8M9HC It is a much higher capacity device than this one and the biggest difference is that it comes with a cable and tips for plugging into a laptop's input power port, not just a USB port.

Yes. You can charge it from a computer using the USB connection, or charge it from an outlet if you also have a USB plug adapter.
