Many models also offer LED flashlights with several light modes, including High, Medium, Low, SOS, and Strobe. LED Light: energy high efficient LED flashlights are built-in in some battery-powered fans as an auxiliary light for use not only in emergencies but in all situations where a reliable light source combined with a cooling fan is needed. While Bluetooth Low Energy (BLE) devices require almost negligible additional energy, WiFi-enabled battery-powered fans should be turned Off when not being used for some time. Smartphone App Support: some models support WiFi and/or Bluetooth connectivity, allowing the users to control the fan settings via a smartphone app. Having IR remote control requires some extra energy which is practically negligible when compared with the energy required for the fan to operate. These fan settings are usually fan speed, timer, and fan On/Off. Remote Control: some battery-powered fans feature IR remote control, allowing the users to change the fan settings remotely. Thus, battery-powered fans can be used during blackouts, emergencies, when camping, on construction sites, and in other situations where cooling airflow can help.īattery-operated fans range in size, airflow (volume), airspeed, battery type, size and capacity, and other features that may include: The main feature of the battery-powered fans is that they are operated using the energy stored in onboard batteries, allowing their users to move and use them regardless of the presence of the mains power. Types and Features of Battery Powered Fans So, when looking for a new battery-powered fan, be sure to choose according to your own needs and requirements. Battery-powered fans range from small, ultralight handheld units to larger, jobsite battery-operated fans powered by large, powerful lithium batteries.īattery-operated fans don't rely on mains power and can be used practically everywhere, allowing smaller and more compact fans to be carried like other wearable electronics.īattery-powered fans differ significantly in size, features, air flow, energy source, requirements, etc.
