wopow is also a mobile power supply, and its counters are not small. Take a look at the legendary mobile power supply with 3G router, this design is more characteristic, connected to the network cable or 3G network card can be directly converted into WIFI signal. This is a good thing for smartphones, but this mobile power supply is too thick, and the white plastic texture is not high grade. The price is acceptable. 499 with a router is interesting.
