A practical and powerful portable power bank
Most mobile power sources on the market have mainly used capacity and appearance as selection factors for many years.
The function is usually just to charge the mobile phone with a data cable connection, 10W to 18W input/output,
Although it can meet the needs of most mobile phone users,
But for people who go out frequently, use computers, use multiple devices in the field and travel long distances,
The capacity is too small, the charging power is too small (not suitable for notebook computers), the self-charging speed is too slow,
There are too few interface types, the voltage is not adjustable (cannot adapt to multiple devices) and other factors,
The popular mobile power supply on the market cannot meet the demand.
