If you have a disposable vape with a USB port, it means that the device is rechargeable. That’s a great thing for you because rechargeable devices are the longest-lasting disposable vapes on the market. Unlike a traditional disposable vape – which you’ll need to discard when the battery dies – a rechargeable disposable vape has a battery that you can top up several times. You can continue using a disposable vape with a rechargeable battery until all of the e-liquid is gone.
