Description

Handheld AC/DC mobile power

The present invention relates to a mobile power source, and more particularly to a handheld AC/DC mobile power source having a function of converting direct current (DC) into alternating current (AC) and having alternating current (AC) output and direct current (DC) input/output.

The lithium battery used in the current mobile power supply is the same as that of the general mobile phone battery. The service life is about 1~2 years (depending on the user's usage). When the service life is up, the internal battery cannot be disassembled and replaced. throw away. There are hundreds of millions of units in the world, causing unnecessary waste of resources, which will cause environmental catastrophe on the earth.

Commercially available mobile power supplies are more than 95% of the power output. The conventional mobile power supply uses a USB slot and is separated by voltage/current. It provides a tablet such as a mobile phone or a working voltage of only 5V, but for the output. For users with higher voltages (more than 5V or AC AC power), most of the existing mobile power specifications do not provide a high voltage/current output, so they cannot be applied at operating voltages higher than 5V or more of electronic products such as notebook computers and other mobile electronic devices. Some commercially available high-end mobile power supplies can provide a variety of high-voltage output, but need to set or adjust the DC DC voltage. If the voltage setting is wrong, the machine will be burned, and the brand-specific adapter will be replaced to be charged. The exclusive adapters of different brands provided by the products, the products of other second-line brands can not be used because there is no special adapter, which is very inconvenient in use.

(1) 95% of commercially available mobile power supplies use built-in fixed non-removable batteries, which are not environmentally friendly and cannot provide unlimited power supply.

(2) The traditional mobile power supply cannot provide a safe, reliable and cost-effective high DC voltage (>DC5V) output due to the bottleneck limitation of the battery series charge and discharge management technology, and cannot provide high-performance DC-to-AC function.

(3) The DC interface of notebooks/tablets and other computers are different in specifications. Most commercially available mobile power sources cannot provide charging due to low voltage. A few rechargeable ones are complicated and unsafe to use.

(4) The commercially available mobile power supply cannot provide backup power for the AC power supply during a power outage.

(5) The traditional AC power supply can only use the action power of the lead-acid battery, which is cumbersome and difficult to carry, and the battery is not easy to replace and the price is high.

In view of this, how to eliminate the above-mentioned defects is the technical difficulty point that the inventor of the case wants to solve; however, the inventor of this case is based on years of experience in the relevant industry, after many years of painstaking research, trial improvement, finally Successfully developed the case and made the invention born to enhance the efficacy.
