Had bought the vapor zeus and returned it although built great it fires at a constant 5 volts which is just too much power for me. juice tasted burnt. So returned and got the xl vv auto battery. I love this thing, the auto is so nice and they sell great cartos that go with it. Ironically I'm liking the 4.8 volt setting... So close to the zeus setting but it's hitting great. I just wish they offered mini USB charging port, no charging in my car will eventually be a bummer. This device and v4l service is top notch.
