Now people on the mobile power supply demand is more and more, many manufacturers see this business opportunity has flooded into this market, then a variety of customized mobile power bank supply has come out, so that many consumers do not know how to choose, the last article with you to understand the three points:Appear, capacity, cell, today Xiaobian will take you to analyze a few other points in the custom mobile power supply.

    4. Support input

    The general input voltage of the mobile power supply is 5V, and the support input current is 1A and 2A. The greater the support input current, the shorter the time it takes to fully charge itself. Of course, the higher the price of the mobile power supply, but the slow charging is advocated, and the fast charging is quite harmful to the mobile power supply.

    5. Support output

    The general output voltage of the mobile power supply is 5V, and the supported output current is 500mA, 1A, 2A and 3A. The larger the supported output current is, the shorter the time it takes to fully charge the task, and the higher the price of the mobile power supply is.

    6. Security

    Safety refers to the protection against overcharge, overdischarge, overcurrent, overvoltage, short circuit, explosion, etc.The key to the safety of mobile power supply lies in the selection of its protection board circuit design and components, coupled with fine technology, will greatly improve the safety factor of mobile power supply, and choose a brand power supply(power bank samsung , jumia ) , will be able to better ensure the safety of mobile power supply.

    7. Conversion rate

    Mobile power conversion rate is the ratio of the actual output power of the mobile power supply and its labeled capacity. The higher the conversion rate, the more the actual output power of the mobile power supply is, but the conversion rate is usually not marked. When choosing and buying, it should take the initiative to ask the business clearly.At present, most of the mobile power conversion rate in the market between 60% and 80%, more than 80% is a good mobile power, and the mobile power supply produced by Longwei Sheng are all star cells, the conversion rate is more than 85%.
