If your vape has been sitting in a cold car for an hour, don't panic. Bring it inside and let it warm up gradually—about ten minutes at room temperature. Use your hands to warm it faster, but don't put it on a radiator or use a hairdryer. That can damage the battery. Once it's warm, give the mouthpiece a wipe and try a gentle puff. If it still feels weak, let it sit a bit longer. In most cases, a disposable vape recovers fully after warming up. If it doesn't, the wick may have scorched—that's a sign to replace the device. And if you ever see e-liquid leaking around the base, that's usually because the device got too cold and the pressure changed. Wipe it down and store it upright going forward.
