Theoretically, a 10,000 mA/h device has to charge a 5,000 mA/h smartphone twice, but in practice it does not happen.

< p >< strong > backup buffers
< p > to extend the life of the batteries, both returns and smartphones reserve part of their container to prevent redundance and recharge. The returns of these buffers are larger as they have to work autonomously and store more energy.
< p >< strong > weak cooling 0 ~/p > < p >High temperature impairs battery operations. Smartphones use complex cooling systems, and returns (especially budget models) are less effectively removed by heat, which is why a part of the charge is lost.
< p >< strong > battery wear
< P > Rotbanka are not updated as often as smartphones, and can be stored for a long time in stock before sale. During this time the battery loses part of the capacity even if not used.
< h2 > How to choose a good return
< P >< Strong > Pay attention to the “real” capacity
~ ~ < P > It is usually approximately 60% of the declared. For example, at 20,000 mA/h will be about 12,000 mA/h of available capacity – this will be enough to charge the smartphone 5,000 mA/h almost 2.5 times.
< P >< Strong > Check the specifications 0 ~/p > < p > Some manufacturers indicate how many times the return can charge a specific smartphone. For example, if a device 20,000 mA/h promises 3 full charges of Galaxy S24 Ultra (5000 mA/h), then its real capacity is about 75%, which is very good.
~ < p >< strng > Study the reviews
< P > Avoid unknown brands – they often use cheap components and simplified protection schemes that reduces the reliability of the device.
< p >< strng > Choose the leading returns
< P > Wireless charging is less efficient, causing overheating and additionally consumes energy. In addition, magnetic returns are more expensive, but the convenience of their use does not always justify the price.
