Problems solved by technology

However, since there is no voltage stabilizing module designed for emergency charging of charging treasures on the market, the traditional voltage stabilizing modules used in such charging treasures are designed for power frequency signals, and are stable for interference generated by hand-operated power generation or solar power generation. The voltage effect is poor, resulting in unstable charging status when emergency power generation is used to charge portable devices

Description

technical field [0001] The invention relates to a portable charging device, in particular to a multifunctional charging treasure. Background technique [0002] With the popularity of portable smart products, charging treasures for power replenishment have become an essential item for people to travel. Existing charging treasures store electrical energy in lithium batteries in advance, and when portable smart products are low in power, they are charged by lithium batteries. In order to avoid excessive power consumption of the power bank, many power banks capable of supplementing additional power are provided in the prior art. For example, the Chinese utility model patent CN206471880U discloses a multifunctional mobile phone charging treasure, which utilizes a hand generator or a solar panel to supplement the lithium battery of the charging treasure. However, since there is no voltage stabilizing module designed for emergency charging of charging treasures on the market, the...
