could this item be used to recharge the battery of a laptop in the event of lost AC power during a black out?

I haven't tried. My laptop has a 3 prongs on the cable for the outlet but hand crank generator has 2 holes as shown on the picture. If you wan to remove the third prong and try it, go ahead. Personally i don't think it will work because it can only power small appliances.

it would take a while to charge it up. but if you set your power management to dim the screen on batteries or if you unplug from a ac source and your monitor dims, then you can connect it to the k-tor and give it a spin if the screen gets brighter then if works, i think if you go to the k-tor site they tell you to charge a power wheel 12volt and use that for the laptop but it is with the pedal version. you could also try a car battery or your car with a converter, this would be alot faster. if you didn't have any other option you could but it may be an all day project.

Not with a three-prong grounded plug-the K-Tor unit only has 2-prong socket. Also, the K-Tor's 10-Watt power is unable to power up the higher-Wattage laptop.

The box shows audio, video, tablets & small games, sorry. This works great for cell phones though.

This charger is good only in case of trying to get enough charge for a short emergency cellphone call because it takes a great effort to get power. the good part is it gives out 120 Volt DC electricity which in some cases could be useful.

Yes it will work for that. That's the main reason I bought it as well. I've left it on for about 20 hours straight running a clock and charging multiple phones and a tablet and it hasn't run out of juice on me yet. A laptop would probably suck down a little more power though so I'm not sure how much of a difference that would make. *We use ours in our rv when we don't want to have the generator on. It's been the perfect solution.

I would not. This is not a heavy duty device. It has small clips and small wires. It is designed to provide power to devices directly from the battery.

Yes, if battery charged. Can purchase additional ac cord for longer use. Can also power through computer.

My guess would be yes because it has needs a power supply which it gets from it's own plug in. Also, it remains lit up when the computer is off. That being said, I have not tried what you ask.

yes you can. Even though your laptop doesn't charge it should still be able to work with the power cord plugged in. If that's no good, then you need to remove the hard drive from the underside of the laptop, then plug the hard drive into a "universal storage adapter" (available on Amazon), then plug the other end to another working computer (USB slot), and pull out the data.

NO, your laptop won't have enough power. I tried that, it didn't work for me. Make sure you tell them to give you a U.S. adapter if you order it because you will get one from ASIA, if you don't.

It possibly could if you plugged into a USB port that had a battery or power. I use it on the laptop fan/pad. It connects to the pad and also to the computer. The computer powers the fan/pad through the cord. I'm sure you could use it in other situations if the power source had a USB port.

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

Should work as long as the device not being used is completely powered off.

I'm not sure. I think it would work. Sometimes I need to login on the laptop and that could stop everything. You can try and return the cord if it fails.

I think it should, however if it is an appliance drawing a lot of power I do not know how long it would last. As a comparison, it can charge a normal laptop at least twice...which would be about 5-10 hours of computer use time. Beyond this I am not sure.

Probably not, unless you have a USB adaptor to your power input to your laptop. Even then, I don't know the output requirements for your laptop... which could be a lot higher than 5V/1Amp (which is this device's output)

The DC output only puts out 2A through 9V, and 1.5A through 12V, so probably not unless your laptop is ultra, ultra low-power?

I would absolutely NOT try doing such a thing. Power supplies for laptops need to be properly regulated and filtered. It will not be a continuous supply of juice, but the voltage and amps will gradually drop the longer you have it connected. And you would need to know the polarity of the connectors for the laptop and battery box so you wouldn't fry the laptop having it hooked up wrong. Plus the connectors would have to match. If you value your laptop, do not try this.

Yes. I purchased it to replace the same battery that was in my home alarm unit. It serves as a back-up power supply in case of a power outage. It works dependably when the electricity fails (that doesn't happen here too often).

No. A battery backup is less necessary than most people think and unless you live in an area with frequent/rolling blackouts I'd just get one of these and spare your wallet.
