I am bringing the whole house when I travel! Just kidding folks! of course, I do bring travel gadgets when everytime I travel. First on the list are my cameras with batteries in it. Why cameras? I always bring at least 3 cameras when I travel. I have a canon camera that uses rechargeable batteries. If you are looking for maha powerex here, just click this link.
