I had two of the biggest and most powerful cell phones of the day. One was made by Mitsubishi, it was about the size of a Twilight novel, corded, and had a 2 watt power level. Cell phone strength at that time (mid 80's) were measured in wattage. The only pictures I can find are for the Mitsubishi Romer, but the version I had was with a larger battery.
The second phone was made by Sony, also a 2 watt phone, but it was about same the size of a Motorola Brick phone. It snapped into your car and could be "hands free" as you drove, or you could detach it and carry this 3lb lead weight along to important business meetings. The phone was also corded, but considered mobile. The battery on this thing was red hot all the time.
Anyone a former L.A. Cellular customer? They've got stories to tell.
I keep hoping these devices gave me some sort of mutant superpowers given the amount of radiation they put out. People make me mad, but I don't turn green and SMASH things.
