About rated capacity

Throughout the market, the total battery cell capacity of the power bank is generally described on the product page, and is usually measured in the lab at a nominal voltage (generally between 3-4V). When a power bank charges a device, it needs to be boosted and converted into energy according to the needs of the device and the charging protocols before charging the device, and at the same time, through the loss of charging cables and the impact of different temperatures, this conversion will lead to natural energy loss (Joule’s law). Conversion efficiencies are generally in the range of 50-70%, and the higher the power output, the lower the conversion rate will become, which is a common feature of all batteries on the market. The actual capacity released after conversion is the rated capacity of the batteries.
