Good portable laptop chargers?

Hi. I recently bought an Acer Aspire V Nitro (http/www.amazon.com/Acer-Aspire-Nitro-VN7-591G-76JG-Bluetooth/dp/B00QNT8WTS/ref=sr_1_1?s=electronics&ie=UTF8&qid=1438044685&sr=1-1&keywords=acer+aspire+v+nitro+vn7-591g-76jg) for college. I love the laptop so far, but it only gives me around two hours unplugged when I'm browsing the internet and such. Therefore, I want to invest in a portable laptop charger. Does anyone know of any that would work with my type of laptop? Thank you!

How do you have a laptop charger that isn't portable?

I'm not talking about the type of charger where you have to plug it into the wall for the laptop to charge. Since the battery of my laptop isn't removable, I can't just buy another battery and have two to use to increase my battery life. And I won't have the luxury of being able to charge my laptop via an outlet on a wall every hour.
