Design and Build
The Energizer Hardcase H591S was designed with toughness in mind, featuring an IP68 certification for dust and water resistance. This means it could withstand submersion in water up to 1.5 meters deep for 30 minutes, making it suitable for challenging environments. The phone's dimensions were 164.2 x 79.4 x 12.2 mm, indicating a robust build. Weighing in at 260 grams, it was heavier than most smartphones, providing a substantial feel that underscored its rugged designation. Its hybrid dual SIM slot offered flexibility by supporting either two SIM cards or one SIM card and a microSD card for expanded storage.
