The combinational modules can be fast assembled with a shell body and a circuit unit to have a more flexible and wider usage. It is not necessary to replace the whole charger to match a different portable electronic device, hence lessening economic burdens to users and greatly lowering the production cost.

[0008] Another object of the present invention is to provide a fast combinational charger having both the functions of a placement seat and a common charger for portable electronic devices such as mobile phones and personal digital assistants. Moreover, two clamping pieces of a clamping mechanism thereof can clamp and fix a portable electronic device so that the electronic portable device cannot move, and contact terminals of the electronic portable device can exactly contact with contact terminals of the charger.

[0009] To achieve the above objects, the present invention provides a fast combinational charger, which comprises a shell body, a circuit unit, and a combinational module. The shell body has a receiving space therein and a bearing seat at the outer side thereof. The circuit unit is disposed in the receiving space, and has a first connector. The combinational module is composed of a module shell body and a module circuit board. The module circuit board is disposed in the module shell body. The module circuit board has terminals thereon protruding out of the module shell body. The combinational module can be placed on the bearing seat. The module circuit board can be connected with the first connector to achieve electric connection with the circuit unit. A fast combinational charger is thus formed.
