By now most of you out there should have already made plans for the summer, some of you may have decided to visit relatives while others may go to a place at the beach, visit foreign countries, go on a mountain excursion and so on. Personally i obviously prefer going both to the beach and the mountain and although these two destinations are the best one can be at regardless of the time of the year there's but a single problem that applies for both and that's that there aren't any electrical sockets around when you are not at the house/resort so if your smartphone is running low on battery then there's not much you can do about it. Because of such emergencies i always carry two portable batteries with me, one placed in my car (charging smartphones from your lighter socket is not the best thing to do) and another in my backpack. Today we will be taking a look at one such portable battery and more specifically the latest PowerBar 4400mAh by our friends over at Sandberg.
