The utility model is realized above-mentioned purpose through following technical scheme; A kind of charger for mobile phone with power backup output function; Comprise that charger housing, attaching plug, functional circuit plate, lithium battery, division board, heat-insulating material, transfer switch, USB output socket form; It is characterized in that: install division board and heat-insulating material additional between charger housing internal strength ability circuit board and the lithium battery; Charger housing upper and lower side is all established the cross-ventilation heat dissipation channel, and transfer switch is installed in the bottom of charger housing.
Described charger housing is rectangular streamline shape, comprise upper cover plate a, middle casing b and bottom c three parts combine form, upper cover plate a and middle casing b periphery leave heat radiation slit gas channel, are provided with bar shaped air heat radiation window below the bottom c.
Described attaching plug is the rotatable folding formula, and the outside rotation of plug is stretched out the grafting civil power for 90 ° during use.
Described functional circuit plate comprises AD power-switching circuit and DC-DC booster circuit; Being used for the civil power step-down converted to charges for behind the 4.2-5V direct voltage self-contained battery and battery of mobile phone simultaneously; When going out to the mobile phone emergent charging; Through transfer switch, connect behind the DC-DC booster circuit 3.7V lithium battery pressed and rise to 5V and offer charging mobile phone battery and use.
Described lithium battery adopts the 3.7V1200-2800mA polymer Li-ion battery.
Described division board can use the good fire-retardant plastic plate of various withstand voltage insulation property, epoxy resin board or fish paper plates such as PP, PET, ABS, PC, thickness 0.3-1.0mm.
Described heat-insulating material can use the good heat-insulating material of various heat-insulating properties, like the cotton plate of EPE pearl foam, ceramic fibre heat-insulating cloth etc., thickness 1-2mm.
The beneficial effect that the utility model produces: this charger has the function that power backup is exported to the mobile phone emergent charging, makes the migrant person when mobile phone cuts off the power supply, give cell-phone charging convenient and swift, has ensured uninterruptedly carrying out of mobile communication contact, has practical characteristics.
