NOVELTY - The utility model claims a multi-port two-in-one charger, comprising a lower shell, a top shell, a main circuit board and a battery, wherein the battery is fixedly connected with the electric core. In the utility model, the main circuit board and the battery are stacked, then each element is set at the outside of the battery, the whole structure is compact, the charger keeps small volume, under the premise of small volume, the upper and lower shells increase the graphene sheet to reduce the heat inside the charger, and the heat is uniformly heat-conducting to the shell through the graphene, which makes the temperature of the whole machine not too high, then separating the battery and the element through the L-shaped retaining wall, at the same time, one side of the retaining wall close to the element is added with L-shaped insulating paper to isolate the contact of all elements and the electric core, The mounting structure firstly can solve the regular distance between primary and secondary, then can isolate the heat conducting of the heating element to the electric core, avoiding the electric core heat is too high, thereby reducing the use temperature of the whole charger, reaching the effect of reducing the temperature when using under the premise of small volume.
