Charging bank case silicone case is not safe. Because for the charging treasure, when the charging treasure charges the device, because the charging treasure can repeatedly charge and discharge the battery inside, the charging treasure will heat up, if the charging treasure set this silicone sleeve, yellow 8 will affect the heat dissipation of the charging treasure, and the safety of the charging treasure will be affected for a long time. It could be a safety hazard. So the charging bank can't have a silicone case
I think it should not be safe, if the silicone sleeve will definitely affect the heat dissipation function of the charging bank
