Nothing with a wick will work for straight hash oil/wax, you must dilute with glycerin/limonene. Direct drip atomizers (google that term plus your ecigs thread type) have no wick and are just a heating coil at the bottom of a tube, they will work with solid waxes, but like all the ecig/vapepens they burn more than they vape. If you want a portable option, may I suggest a wand/concentrate bowl and a mouthpiece glass on glass adapter? I know the ecigs are pretty and cool but man they burn away a lot of your oil and taste terrible.
