The utility model relates to a portable portable power of acquisition terminal test, specific existing field test of acquisition terminal uses portable power that says so. Including box, inverter circuit and the storage battery of setting in the box, the inner chamber of box passes through the baffle to be separated for electrical store and cable storehouse, and inverter circuit and storage battery are installed in the electrical store, are provided with operating panel on the box corresponding to the electrical store, the last voltage output of the being provided with terminal of operating panel and the knob of shifting, and the storage battery is connected to inverter circuit's input through the wire, and inverter circuit's output is connected to the voltage output terminal through the wire. Its simple structure, low cost, installation are easy, convenient to carry, can effectively provide the voltage of different brackets according to different terminals, ensure that the various parameters of acquisition terminal are correct, and the condition of having avoided the staff to make a round trip to come and go has reduced intensity of labour and labour cost.
