You're welcome, it's a great feature IMO, when I had my spinner, I struggled more with trying not to smoke while it was on the charger. Just try to find a good reliable pass through device with a higher mah rating if you're lifestyle doesn't allow to be close to a USB port and if you are a heavy vaper and like the higher voltage settings.
If you are willing to invest a little more, many ECF members recommend getting the MVP2 which also has a pass through but has a 2600 mah battery and can be found online from about $50-100 depending where.
I'm not recommending this site, but linking to show you the product.
