I'm looking for a vape pen or a portable vaporizer for dry herb.i have an airizer solo but I lost the charger and it didn't really give me much of a buzz. I got a DGK G Pen but it doesn't work right. It heated up a little and shut off, luckily I got my money back on it. I need something inexpensive as I'm low income. I'm a medical mj patient who was just recently diagnosed with asthma. I need herb for fibromyalgia and arthritis. On the other hand it could be my tolerance as to why I don't get a buzz vaping. In that case does anyone know where I can buy a charger for the solo?
