How to achieve mobile power with lithium batteries? Used to charge cell phones and MP3 players!

The main considerations for using lithium batteries as mobile power supplies are: the input DC voltage of commonly used digital products is 5.0V when charging, and the terminal voltage of lithium batteries is 4.2V when fully charged and less than 3.7V when fully charged. completely discharged; so you just need to increase the voltage from 3.7V~4.2V to 5.0V. There are boosters on the market, but their manufacturing efficiency cannot be guaranteed.

The voltage of two batteries connected in series is 7.4 V to 8.4 V. It is certainly not possible to directly power digital products. The only way is to reduce the tension at the same time. of two lithium batteries connected in series is also very inconvenient, if connected in parallel, it is the same as a single battery.
