This Transistor Pack E comes in two versions, Battery Magazine and Ni-Cd Pack. The former includes Battery Magazine TP and Connecting Cord E while the latter uses a Ni-Cd Pack TP and the same Connecting Cord E. With the Battery Pack version, the user needs to buy six units of C-size batteries to power the Transistor Pack E. With the Ni-Cd Pack Set, it uses a Ni-Cd Charger TP to recharge the Ni-Cd Pack TP in approximately 15 hours. Aside from being the optional battery pack for the Speedlite 480EG, this accessory can also be used with the Speedlites 430EZ, 540EZ, 550EX, MR-14EX and MT-24EX.
The Transistor Pack E, whether one buys it as the Battery Pack E Set or Ni-Cd Pack E Set, is supplied with a carrying case where the photographer can attach it to the belt or simply slip a strap into its two loops and carry the pack over the shoulder.
