Portable games have seen a massive rise in popularity over the past ten years with the advent of many newer technologies that put them on par even with console systems. The portable games of today are often so graphically intense that many people only own these portable devices and shun the consoles altogether. In terms of their benefit on a long trip, their importance can't be overstated. However, you do need to take into account the fact that these machines use a lot of battery power and therefore require a bunch of recharging. Because of this, you will find it to be in your best interest to invest in a car charger for your portable games. This way, you never have to be without your favorite games.
