Am I able to charge this unit with a portable solar power panel &amp; run my laptop on it for at least two hours?

The battery in this is a "22 amp/hour", so it should be able to give you 22 amps for 1 hour, 11 amps for 2 hours, etc. If a laptop needs 1 amp at 120V AC (which is the same energy as 10 amps at 12V), it should last 2 hours. You want to keep a battery like this charged 99% of the time (or it loses it's ability to hold a charge), so I hope you actually start with it charged, then recharge it ASAP after using your laptop or such. A solar panel can charge this, but I hope you realize how long it may take to fully charge it. If you have a "60 watt" solar panel set and connect this up, it will take at least 6 hours to charge it (which I get from saying 60 watts/15V charge power=4 amps charge supply and 22 amp battery/4 amps supplied=5.5 hours to fill it up). Other solar panels can be calculated how fast they'll charge in a similar manor to that by just trading out the solar panels watts rating, coming up with a different charge amp supplied, and dividing that into the 22 amp/hour rating. Some solar panels (like ones I got) don't even perform at 1/2 their labeled rating in what I'd call "ideal conditions" (not to mention cloudy conditions), so it may take a lot longer than what I said in reality.

You would need four or five units to achieve what you need. Would probably be cheaper to charge it with a regular charger for several hours then hook the solar charger to maintain the charge.

The solar panel needs a good charge controller and battery. If you have that covered, I would say it could run that gear easily.

If the powerpack has a 12V input, or you can connect directly to the battery, it should work fine. The controller that comes with the solar panel acts as a charger, and switches to a "float" mode when the battery is fully charged. You can leave it connected.

The plug-in charger only puts out 2 amps. If your solar panel USB port has similar output there should not be a problem.

I guess so it can be done. The unit can be charged via regular power outlet and using computer (USB port)

I really can't answer that question, maybe see how big the battery is in the computer and compare it with this unit? Can you charge your puter with a usb cord? if you can it would probably run it for a short time.

I need it to run the computer while I use it. the internal battery goes dead quickly (less than 1 hr) while using unplugged. Need it to power computer in use for 3 hrs using multiple applications.

It can be recharged as long as the solar unit can put out 5Amp hours of charge, if not it will take a long time. At 5Ah it will take 11 hours from a completely discharged battery

This will vary wildly on your operating factors. For example, will you have the screen on your laptop on and at what brightness? Will any physical drives be operating or are they SSDs? What processor do you have (older gen Intel i7 chips will shred through the power quickly). Will this also be powering the weather station in any way? What is the temperature and humidity where the unit will be? It becomes a big math equation based on the draw of your connected equipment. Most laptops have a 60-90w power supply, but don't necessarily draw that much at all times. Looking at the manufacturer's provided runtime graph in the product details on Amazon, you can get a rough idea that you would expect well over 90 minutes runtime for a load &lt; 100 watts. I can tell you my desktop computer with i7 chip and LED monitor is showing 122 minutes runtime (untested, unconfirmed) so I would say most laptops would be in the 2-3 hour range.

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 do not know for certain, but i belive you might be able to do that , but it would most likely keep the power pack on a low battery until you let it charge without draining it at the same time. I hope that helps

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

Not really it's going to be a waste of energy . I plugged it 2 hours before using it.

Yes, that is how I operate the unit. Use a solar panel with a minimum power of 25 watts, attach it to a 12-volt car battery using a solar charge controller.

Anker makes some fairly nice USB batteries that you can buy on Amazon for under $50. You could use one of those batteries with the solar array and have power left three days later.

Sure, I plug it into a 12v back up battery I charge with a solar panel. But you could use an outlet.
