will power laptop and still has two usb charging ports [SEP] this is a review of the silicon devices high performance auto power inverteri have this in my suv to allow me to use my laptop on the go my laptop i use for travel is older and has no battery that keeps a charge it also charges my phone but that need is rare as my phone battery keeps a nice chargefor those who may not know what a power inverter is it is a basic device that you can plug into a dc vehicle outlet and converts it so you can use an ac device dc outlet to ac outlet this one does have an extra bonus as it throws in two usb charging ports the usb ports are rated and use the higher one for your tablets and heavy power hungry devices this takes in dc and puts out up to watts which is plenty for normal ac devices such as laptops and portable electronics it is only oz and measures x x it is made of metal and is very durable so you can toss in your glove or utility box so it is ready to go cable is also nice and long so you can reach from front of the car to the middle area so others can use from all the other seatscons one thing i did notice is that the dc plug did not have a fuse in line the description indicates this has over and under voltage protection however i am not clear if this is for the usb ports and or if this applies to the ac outlet as well other inverters typically offer fuses or a fuse if you remove the end cap on the dc plug on the up side the soldering inside the dc plug was very nice and solid with nothing loose or questionable tips notes make sure your vehicle is running when you use this this has potential to draw a good deal of power if using the upper range of and can run down your battery if the vehicle is not on allowing your alternator to prevent battery drainagesummary this works as described and is very small it has a built in fan to keep this cool as it works it is very quiet and does what is expected i would recommend this to friends and familyi don t know about you but i depend very heavily on reviews that are posted on amazon i also read what reviewers on amazon have to say i want to help others by providing my reviews that detail the product as well as the experience i have with the products that i get on amazonplease note i have no relationship with this seller and i m not compensated in any way for my review i did receive this free in exchange for an unbiased and honest review i take my reviews serious and will only provide my true feedback thank you
