For the charging belt WIFI used on large hillsides, we need to pay attention to two main aspects, one is its network coverage ability, and the other is its battery life. Because on large hillsides, telecom signal coverage will be affected, it is necessary to choose a charging bank with a strong network signal. At the same time, because the battery life of modern power banks has been improved, we recommend choosing a higher mAh (mah) capacity to ensure sufficient power when used, and should choose the fast charge technology required for some mobile phone models in order to charge quickly. In short, to use the charging bank WIFI on the big hillside, we need to choose a charging bank with excellent signal and battery life.
