can you charge this battery while you use it to power your laptop ?

Never tried to do that; but NOT sure why you would want to do this? The battery does not charge the notebook battery so if you trying to avoid carrying notebook charger this would only allow you to power notebook but not charge notebook internal battery. It would seem at some point your notebook battery would run low on power that this battery pack would not meet demand.

No. It is not intended for that purpose. It is intended to charge electronics that charge through usb. Laptops require a higher input to charge them that usb can give

Yes, you can charge the battery with the USB cable that goes to computer and it also comes with an external wall charger. Also a second battery was included so you will always have a spare!

yes it is rechargeable via usb to your laptop.It will power up even if the battery runs out of its reserves. It should be powering up each time the Alpen is connected to a power source via USB port

Yes you can, but it's best to finish everything and let it charge sense this charger has a power limit.

Yes and there is an usb port on it as well. This way while the battery is being charged you can charge something else using your usb cable.

If your laptop's charger can connect to a USB port it could. But most likely your computer/laptop power supply (charger) connects to an outlet. This portable charger only charges devices that can charge through a USB. If not than anything else won't charge.

Hi! I did not try, but its capacity is 6000 mAh, so it should fully charge <= 6000 mAh battery notebook. My notebook has 5200, for example.

No, you don't have to charge it. Just plug it into your computer and use it.

Yes, it can. My son used it over a 7-day period where he had no power, and he loved it. I don't know how much it will charge a computer, but it is one of the most powerful out there. How will you be using it?

If I remember correctly, the battery had a partial charge when received. However, we followed the instructions and charged it for several hours before trying to run the laptop on battery power.

I've never tried that, so I'm not sure. However, it has the ability to plug into an electrical outlet which I assume would give it the power to charge electronics on its own, without being connected to the computer. It might be worth checking with the manufacturer, if possible.

Never tried that - but it runs while plugged in to an electrical outlet, so I don't see why it wouldn't run while charging from your laptop.

Yes, you can charge the 12 volt battery while the inverter is powering your appliances and electronic devices.
