Heated Vest Versus Charger: Surprising Warmth insights... Winter Tested We’ve tested our ORORO Men’s Lightweight Heated Vest through harsh winter conditions, comparing its warmth directly with the included battery pack. The vest delivers surprisingly efficient heat, especially around the torso and back, making chilly commutes far more manageable. However, we noticed the battery pack depletes faster than anticipated, especially at lower heat settings. While it’s convenient to recharge the pack separately, we found ourselves planning commutes with longer breaks to ensure warmth. The lack of an included charger adds minor hassle, but the versatility of the setup outweighs it. The vest’s weight and thin design also make it practical for layering, though we’d recommend bringing extra layers for extreme cold. Overall, the warmth is impressive—just remember to keep that charger handy.
