We featured many power banks here at CoolPile.com, but, for some reason, we always focused on external batteries designed to charge small gadgets such as smartphones, digital cameras, tablets, basically everything powered and charged by USB cables! Check out some them here: the JunoJumpr, the PoweriSite, the PowerPak Ultra, the TsirTech smartphone wrist band charger, the PowerFlask and so on …
Now it’s time we get more serious into this power banks situation! A while back I was looking for an extended battery for my laptop and soon I realized that it makes no sense to put money into an battery which will serve only one gadget – my laptop. So I decided to go for an battery powerful enough to charge my laptop, versatile enough to allow multiple gadgets charging and lightweight enough to comfortably carry it in my daily backpack!
While I am still researching the subject and I did not settle for a model yet, the Energizer XP18000 seems to be a serious contender! The device is truly universal, can charge just about anything that gets power juice via USB and can add up to 5 hours of usage to a regular laptop or up to 8 hours of use to smaller netbooks.
The Energizer XP18000 can recharge up to 3 devices at the same time, comes with 3 power cables, 6 cell phone tips, 3 media tips, 9 laptop tips, an AC adapter and a carrying bag. The XP18000 is also part of the Free Tips For Life Energizer program which allows users to get 2 free charging tips every year, for the life time of their registered power bank! So no worry if you buy a new gadget!
