The Energizer E3 suits anyone looking for a basic phone for calls and SMS, with room for two Mini-SIM cards. At 70 g, it is light to carry, although its body is 14 mm thick. Storage is expandable, giving users the option to add space.

Its 1.77″ TFT LCD display has a resolution of 128 × 160 px and a pixel density of 116 ppi. The compact screen is suited to viewing simple information. The 1,000 mAh battery has limited capacity. For connectivity, the phone supports GSM and GPRS on 2G bands, along with Bluetooth 2.1. Its mobile-network options are basic.

Other features include a 3.5 mm audio jack, FM radio, and a loudspeaker. The rear camera supports slow-motion video. The Energizer E3 may suit people who prioritize a light, straightforward phone with Dual Mini-SIM and expandable storage.
