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-cigarette 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® 5V electronic pass through battery utilizes a KR808D-1 style battery and is compatible with all Bloog® electronic cigarette threaded cartomizer tips. It is a non-regulated pass-through, which tends to produce a warmer vape for better vapor production, but it can use up cartomizers faster.
