The Bloog® MaxxFusion Pass Through is a terrific way to experience e-cigarette smoking without having to use a traditional Bloog® e-cig battery. Simply attach your favorite flavored Bloog® e-cligarette cartomizer to the pass through and plug the Bloog® USB plug into your computer's USB port and start Blooging while never losing your charge. The Bloog® 3.6V electronic pass through battery utilizes a KR808D-1 style battery and is compatible with all Bloog® electronic cigarette threaded cartomizer tips. This is a regulated pass-through, which has a cooler vape, but makes cartomizers last longer.
