would this be enough to keep your laptop warm or at least safe enough to leave in a car for couple of hours without freezing?

I love neoprene sleeves for lightweight laptop protection, but it can keep your laptop TOO warm if you're not careful. Neoprene is used in dive suits as an insulator (among other reasons) and it can prevent your laptop from cooling if you shut down and immediately stick it in the sleeve. If your laptop has high temp generating components like gaming graphics cards, then let it cool a bit before inserting it in one of these.

I wouldn't leave any of my electronic devices (laptop, phone, etc) in a car for hours in either the cold or extreme heat. Not only can this affect the device, but it will also affect the battery life. This product definitely isn't designed to protect against extreme temperatures. Its main function is to prevent your laptop's external casing from being scratched while it is inside a backpack or other carrying case.

I don't think the cover makes a difference in freezing, it is for protection in case of spills or dropping. If you were using your laptop before putting it in the cover, it would probably keep in what heat there was already there though.

The battery gets about 3 hours of heavy use, but that varies on screen brightness and if you use the LEDs. As for the heat with very long usage and bottom vents covered it gets hot enough you don't want it on your lap. However I bought a cooler master laptop fan and it sovled the problem

My husband use's his in his semi-truck leaves it on all night but he has 3 batteries. If your car battery is in good shape it will probably be ok , but he said you might want to put another blanket over it so the heat will stay in instead of radiating out.

No. It might keep it warm for an hour or so. But not for a long period of time.

I've played games using it for a few hours, maybe 6 maximum, so yeah it should keep cool enough.Be sure to keep your entire case cool as well with proper air flow.

Well, not really. It's not warm itself. But it does block any air from a fan etc, as anything on your lap like a pillow etc. would.

It does a good job of keeping the car cooler. Nothing will prevent heat from getting in. I have a white car, live in Florida, and the interior still gets warm even with heavy window tinting and the heat shield. Guess it depends on where you live. I am happy with the design.

It does keep you lap cool since the heat is deflected on the lapdesk. the laptop stay the same as it would be laying on a table. Bryan

The cooler can be kept on still if you want, especially if the laptop is overheated. Otherwise if you aren't using your laptop, it's good to at least turn off the cooler. I kept mine plugged in to my laptop 24/7 but would turn it off when I left it.

yes. I got it for my son. he loves it. Keeps the laptop cooled off so it doesn't overheat.

You probably could run your computer without the cover, but it might be counterproductive regarding cooling. PC manufacturers are careful to engineer cooling and airflow to work with the case closed. If the computer sits in a location that has unrestricted airflow, and is not too warm, it should do fine running non-stop. If the ambient temp is much more than middle 70's farenheit, you might need to monitor the temps of the cpu and motherboard to ensure the computer is going to operate reliably.

I own two and it keeps my lap tops cool and running fine . I is on from 6:00 am till midnight. Have had them for 3yr now.

Agree with many other responders -- stays warm for maybe 8 hours -- but definitely not hot after that. Insulation is present, but it's not like a thermos at all.

This should be fine. I leave mine on for eight hours at a time with no overheating problems.

She's a blower but it's almost as if there's a layer of moving air between it and the laptop. Stays quite cool though, only gets warm under heavy load but even then the heat is acceptable. The one drawback which doesn't affect me is that it doesn't seem like it would be very suitable to sit in your lap, otherwise it's excellent. I'm quite pleased with mine.

I use it during school, leaving at about 7 AM and returning around 5, and the ice pack is usually still somewhat frozen when I return home. Granted, I'm not leaving it in a hot car, but I think 12 hours isn't too much of a stretch!

It's plastic, so it doesn't disapate heat in the same way metal would. The middle of the plastic top surface is concave. Most laptop fans are in an area where it would blow hot air out and into this channel. In that way it disapates heat. It also depends a bit on how tall the rubber feet pads are on your laptop. The higher the more clearance there is for air flow. I am using a MacBook. Most of the heat is disapated at the bottom of the screen area. However it works well enough to keep it cool. Most lap desks have similar issues with my Mactop. This is the best plastic surface lap desk I have found. My lap stays cool enough. After long use, my lap feels warmer, but there is padding on the bottom, so I would expect my lap to be a bit warmer just because of the insulating vale alone.
