can I use this to charge a laptop?

I wouldn't. I would only try to charge the manufacture's recommended devices. Otherwise the warranty for the charger most likely would be void. Plus any damage to the laptop would be your responsibility. Also a side note, the manual states that you should not have the charger on and installed when starting the car. Make sure you unplug the charger from the socket in the car before starting the car!

The big answer is NO. Laptops use a lot more current and a higher voltage than this charger is capable of. The good news is that there are a lot of car chargers out there that are made just for about any laptop made. "Pwr+" makes excellent car chargers for laptops and Amazon has loads of them. My Jeep Grand Cherokee's power port will not put out enough current for my Asus laptop charger so I have to use it in the regular cig. lighter receptacle on accessory. Most car chargers are under 20.00 so are a good investment if you travel with your laptop. Also once you have your laptop plugged into your car charger you can use the laptop USB ports for charging USB devices. Hope this was of some help. Harold The big answer is NO.

I don't think so. But you may want to check the Voltage/Amps your laptop needs and compare it to the one this charger supplies. On the other hand I don't know how you are planning to plug your laptop to a USB.
1767877
Not unless you have a laptop that charges via USB. Which I have never seen.

No. If we are speaking of standard laptops then common voltages are 7.2V, 9.6V, 10.8V, 11.1V, 14.4V and 19V. If you have a netbook you will have to find out what voltage is needed. Be sure to get a charger that is for the type of battery you have. Lithium Ion batteries charge in stages and the wrong charger will cause it to overheat or even catch fire. Sorry for the bad news and I hope this info will be helpful

Probably not since the connector on the end is designed to fit a cell phone. It's a micro USB connector. Most laptops take a large round connector.

USB ports are 5 volt and your laptop needs more volts then that ( the Toshiba Satellite laptop power supply I checked was 19 volts). So I would say no.

Laptop goes through a brick which converts AC to DC. It would not make any difference as long as you use the brick. Any decent laptop (Apple,hp, dell) will have proper circuitry to be able to operate. I use it to charge iPhone iPad and Kindle with no problems.

Unfortunately not. It's only for charging portable devices like cell phones, tablets, and any other devices that charge via a USB port.

Wont work as a power supply.....only a charger.....it will recharge the laptop battery and then turn off

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?
654506
yes you can. It will plug into your USB port and it will function normally for all laptops',desktops' & etc., all have them.

Hello Kirpal, From your question it sounds like you want to use it to power a computer. The answer would then be no. This is for powering devices that only use a small amount of power. Make sure that the voltage and current requirements for any device match the output of the adapter. Also, I would not use it to charge or power any devices that are very expensive because there are protective devices in more expensive power supplies that are absent here. Hope this helps.

Unfortunately that's really not how it works. In order to charge any laptop, netbook, etc. you need to connect to its power input port. What you are looking for is something like this: http://www.amazon.com/Energizer-XP18000-Universal-External-Netbooks/dp/B002K8M9HC It is a much higher capacity device than this one and the biggest difference is that it comes with a cable and tips for plugging into a laptop's input power port, not just a USB port.

Yes you could use it to charge an iPad but the USB port would have to put out 2.1 amps in order to charge the iPad properly.

Hello. This charger is meant for charging Cellphones, iPods and similar devices. While it may give you a partial charge for a Laptop, it is not optimal for this purpose. Thank you

I have to assume it would work. The panel outputs 12V. The the mA flow rate would make charging a laptop a long process, probably several hours.
2043903
I'm actually using a spare one for that function now. HOWEVER, it will only charge items at the USB limit of 500mA per port. Most true chargers are capable of 700mA to 1000mA depending on the device.

It could. The distance of the center post may or may not get you to the outside contact of the power supply when you plug it in to the laptop. And make sure you know what polarity goes to what post.

Unless the Laptop chargers via a USB Port, then I don't believe so. The solar charger has a USB out which delivers 5 volts DC. Most Laptops have a transformer connected to a cord which requires 120 volts AC. I would also assume that the laptop battery itself probably would require at least 12 volts DC or more if it could be charged directly. You could get a regular solar panel to do it if it was connected to a 120 volt AC inverter.

If your laptop can be charged with 9 or 12 volts, and it draws no more than 4.5 amps while charging, then yes. However, I'm pretty certain that most laptops require around 18 volts for charging, maybe a chromebook could be charged with this guy, but I would need to check.If you want to post a link to your laptop I could tell you with certainty whether or not you can charge yours with it.

Yes we can charge using laptop. But I do not think it is holding the charge too much time .
