Well, a 'simple trick' is to put a battery across the the leads so that the charger does see a voltage.


From the perspective of tricking the charger, it doesn't have to be a big heavy battery - a 12 volt motorcycle battery would work. In effect you are using the battery to power the vaporizer and supplementing/recharging the battery all at the same time.

Note that I am not necessarily advocating this approach. If you can find an older charger as Thomas suggests, that is a less complicated approach and may be lighter to carry around.

......

Oops, now I see that you have already figured out using a car battery with the charger - so all I can suggest is a smaller battery is easier to carry around.

Both of the vaporizers that snl sells are 150 watts, and I suspect that competitive products are similar. At 12 volts that works out to 12.5 amps. I would expect that a 12 volt 2 amp power supply would not produce desirable results.
