can it power a laptop, and if so, for how long?

Correct Only 5VDC USB charge outputs most Laptops need at least 18 to 24VDC

I Don't think it can. It only has 2 USB ports. And it doesn't hold that much juice.

No, Not for powering a laptop. It's good for cellular phones, IPads, tablets, etc.

Yes, this item can power a laptop, just noy for long. Might have purchased a lemon, but this did not meet my satisfaction.

I guess it depends how long you need it to run in the event of a power failure. If this is your only computer and only need a very short up time before shutting down it may be over kill for you.

Greetings. This power bank can be charged and powering a laptop at the same time.

Find a 2amp wall charger and plug it in to that. If u charge it off your laptop it will take 6 hours to charge...

Doesn't really take that long, I say no more than an hour. But it last the whole week and some. If I'm at my computer I'll just plug it in, but otherwise I don't really worry about it.

Absolutely, this need very little power, you many connect it to your Notebook USB also

Depends on the laptop. But, if you start with a full laptop battery and then use this thing as well, I would expect a MINIMUM of 3 additional hours of use. Realistically more like 5-8 additional hours. If your laptop is older or the processor doesn't use a great deal of energy, then you might get obscenely long usage.

If you can take the battery out and run your laptop on just the power adapter - the battery is dead.My battery only lasted 5-6 months. Initially I got 3 hours on a charge - no more.

Yes. Our setup is consists of the charging panel, an RV battery, and a cigarette-outlet style inverter. With that, we had enough electricity to power our little pick-up camper AND charge cell phones and my laptop on a 3-day camping trip. Without the battery, though, I think you'd pretty much have a trickle charge that would take FOREVER to power up a laptop.

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.

though technically it will work to power your laptop, the replacement is less than perfect as it will not, for all my trying, stay INSIDE the computer. I've had to resort to duck tape. Yes, Duck tape on my laptop. Not pleased is an understatement.

I'm not sure about a laptop but it will power a phone and still charge the battery

I use this for my laptop, it has the three prongs so I don't see why not. Just keep in mind it is not a surge protector, so if there is a power surge there is the potential for damage to your laptop (i.e. don't leave it plugged in during an electric storm).

Yes it has it's own power supply that when charged with the usb cord plugged into your computer will operate on its own, depending on settings, for up to 3 hours. There is also an indicator light on it that changes colors to let you know when it is fully charged.

You can do it without a problem . I used it to charge my laptop with 90W rating.

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

It appears to charge for about a 2 hour lifespan. But that's how long most of the 6-lithium ion batteries charge for. Most batteries last me 6-12 months before they overheat if you use your laptop frequently
