20000 mA =20 A, the charging treasure voltage is generally 4.2v, 4.2× 20 ÷ 1000 = 0.084 kWh, and the power consumption is about 0.084 kWh. Regardless of the loss and charging efficiency, the charging treasure generally has a virtual standard.
Extended data:
1, AC plug type
Mobile Power Supply with Folding AC Plug-Folding Direct-Insert Mobile Power Supply: It can be directly plugged into a household socket to charge the product itself, integrating the functions of charger and mobile power supply, making it more practical and portable.
2.LCD screen display type
Some mobile power supplies in the market have made great efforts on the types of shells and batteries, and developed a mobile power supply with digital display mobile power indicator light. Such products generally use pure cobalt batteries to reduce the error of electric quantity display. The core components of different kinds of mobile power sources simply have two parts, one is the medium for storing electric energy, and the other is the medium for converting other energy into electric energy, so the quality of batteries can be used as one of the important standards to measure the quality of mobile power sources.
3. Volume superposition type
A split mobile power supply, composed of multiple energy blocks adsorbed together, not only looks novel and unique, but also is very fun and interesting. The fuselage is equipped with a liquid crystal display screen, which can accurately display the remaining power. The nominal power of each energy block is 2600mAh, which can be added together to expand the overall total capacity and meet the use needs of users with different power requirements.
