Description

technical field [0001] The invention relates to a portable power adapter. Background technique [0002] At present, power adapters are widely used in electronic products, household appliances, notebook computers and other products to obtain the rated voltage and current required for the product to work. The power cords of the existing power adapters are all connected outside the main part of the adapter. Because the power cords are long, they tend to become messy and inconvenient when storing and carrying them. Especially in some miniaturized products, the adapter part The space occupied is often close to or even exceeds the space occupied by these products. For example, the notebook computer is now smaller and smaller, and it is very convenient to carry, but its corresponding power adapter is still the same as before, or just put the main body of the adapter The volume is reduced, but the power cord and its connection method are not changed. When retracting and carrying, t...

The power cords of the existing power adapters are all connected outside the main part of the adapter. Because the power cords are long, they tend to become messy and inconvenient when storing and carrying them. Especially in some miniaturized products, the adapter part The space occupied is often close to or even exceeds the space occupied by these products. For example, the notebook computer is now smaller and smaller, and it is very convenient to carry, but its corresponding power adapter is still the same as before, or just put the main body of the adapter The size is reduced, but the power cord and its connection method have not changed. When storing and carrying, the power adapter takes up a lot of space, which makes it inconvenient to use. In addition, the appearance of the power adapter and the computer itself is also uncoordinated.
