The portable power source has improved protection functions of overload protection, short circuit protection and the like. The portable power source has small volume and low weight, can be can be used flexibly and taken along conveniently. The portable power source has characteristics of large battery capacity, high inverting efficiency, low heat generation, high battery utilization ratio, and low power supply period. In the utility model, the voltage of battery can be displayed in real time. And a warning can be sent automatically when the power is insufficient. The range f charging voltage for the portable power source is wide and the portable power source has a function of trickle charging. After the portable power source is fully charged, a prompt is made automatically. The portable power source in the utility model supports a plurality of power output forms, such as USB power supply output, 220 V AC power supply output and 12V DC power supply output.

Description

Compact power

Technical field

The utility model relates to power technique fields, relates in particular to a kind of portable power supply that conventional power consumption equipment provides power of alterating and direct current that can be.

Background technology

At present; Numerous areas such as environmental monitoring, safety inspection, emergent detection, gas analysis, biology, chemical industry, scientific experiment all relate to some open-air perhaps high altitude environments, and often power supply is supplied with inconvenient; For example work such as fracture detection by magnetic powder just can only be adopted direct-current power supply; Because direct current does not have skin effect, detection sensitivity is low, is easy to generate phenomenons such as flase drop, omission; Also have digital electronic goods such as some notebook computers, DV video camera, digital camera, MP3, MP4, generally adopt rechargeable battery powered.USB interface then is a kind of standardized interface shape, both can be used for the signal connection end mouth, also can be used as the receiving end mouth.But most of power supply units do not have USB port, and trip, tourism, etc. the situation of charging inconvenience often can not satisfy the power supply needs.

Summary of the invention

To the deficiency that prior art exists, the utility model technical problem to be solved is, provides a kind of and can be conventional power consumption equipment and the AC and DC power supply is provided, compact power easy to use, that power-on time is long, inversion efficiency is high.

For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of compact power; Comprise casing, inverter circuit board, dc-battery group, exchange accessory power outlet with voltmeter and switch; Said voltmeter is parallelly connected with the dc-battery group, and dc-battery group, interchange accessory power outlet and switch all are connected with inverter circuit board; Also comprise the USB interface that is connected with inverter circuit board, on the dc-battery group, be parallel with the direct current accessory power outlet.

Above-mentioned compact power is connected with buzzer, relay indicating light on the said inverter circuit board.

The advantage of the utility model portable power devices is:

1, possesses perfect defencive function, possess overload protection, functions such as short-circuit protection.

2, volume is little, and is in light weight, uses flexibly, is easy to carry.

3, battery capacity is big, and inversion efficiency is high, and caloric value is low, and the battery utilance is high, and power-on time is long.

4, cell voltage shows in real time, reports to the police automatically during power shortage.

5, perfect charge protection function can prevent that battery from overcharging; Charge voltage range is wide.

6, possess the trickle charge function, instrument was pointed out automatically after charging finished.

7, the multiple output form of electric power, the USB output of supplying power, the output of 220V Alternating Current Power Supply, direct current 12V output.

Instrument is formed: casing, battery, inverter, cradle, switch, voltmeter, AC socket, USB socket etc.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details;

As Fig. 1,2,3,4, shown in; A kind of compact power; Comprise casing 3, inverter circuit board 4, dc-battery group 5, exchange accessory power outlet 6 with voltmeter 1 and switch 2; In the bottom surface of casing 3 base 7 is set, voltmeter 1 is parallelly connected with dc-battery group 5, and dc-battery group 5, interchange accessory power outlet 6 and switch all are connected with inverter circuit board 4; On casing 3, also be provided with the USB interface 8 that is connected with its inner inverter circuit board 4, also be provided with the locator card 12 that is used for fixing dc-battery group 5, on dc-battery group 5, be parallel with direct current accessory power outlet 11 in the inside of casing 3; At the buzzer that casing 3 set inside have inverter circuit board 4 to connect, outer setting has relay indicating light 9, alarm lamp 10 and buzzer 13, and wherein relay indicating light 9, alarm lamp 10 and buzzer 13 all are connected with inverter circuit board 4.

Method for using: AC power supply device is inserted in the interchange accessory power outlet 6 of compact power, starts compact power switch 2, power consumption equipment just can operate as normal; Dc suppling equipment can insert (5V power supply port, open state are down effectively) in direct current accessory power outlet 11 (12V direct current supply mouth all can use under the on-off state) or the USB interface 8 according to the voltage difference.

Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection range of the utility model.
