INTRODUCTION

   Time flies by very fast and so once again summer is just around the corner so naturally most people i know are already planning for their highly anticipated vacation. Summer vacations however usually mean going to the beach on a daily basis (where i live anyways) and although in the past that ment only taking a towel and an umbrella with you today thanks to our smartphones, laptops and tablets things have become quite more complicated. Now there are some people who prefer getting up and going all the way to their cars to charge their mobile devices but leaving out the quite annoying getting up part and going all the way to your car that means you can't use the device while charging (not to mention doing so may help deplete your car batter). Portable rechargeable battery packs (power banks) have solved that problem for the majority of people but to date not many people are aware that there are some models which can also be used to charge their laptops and other not so "portable" devices. The AL390 Laptop Power Bank by Xtorm is one such model and we've spend the past month testing it with all our portable devices.

   Xtorm is part of the Dutch company A-solar bv and was founded in 2008 with the idea that today more and more mobile devices come to the market, which requires a lot of power. To contribute to the environment we have searched for durable applications to provide a solution to this problem. Meanwhile we are the manufacturer in the field of innovative and practical solar and power solutions for everyday use. We bring a complete range of affordable and user-friendly consumer products on the market that simply charged from solar power and USB. The products with the brand Xtorm have a contemporary character and are of high quality.

   The AL390 Laptop Power Bank by Xtorm features a high-quality 18.000mAh lithium-ion rechargeable battery pack which can be used to fully charge tablets up to 2 times and most smartphones up to 9-10 times (up to 90 hours of extra operation time according to Xtorm). It also has two 5v/2.4A USB ports for charging of mobile devices but what really separates it from most products of its category is the built-in AC 230v socket which can be used with laptops and virtually anything that uses a wall plug (as long as it's rated for up to 65W). Unfortunately all of the above mean that the AL390 is not the smallest power bank in the market today (far from it really) but all said and done people who are interested in such a device will obviously not be looking for one with just enough juice to charge their smartphones.
