Review title: No power !
Product review: When the unit arrived the internal rechargeable battery was dead. It would not operate even when plugged into a USB, until I removed the battery. Even then it had very little power and did noting for the air around me. I use ionizers on a regular basis so I'm familiar with how they work. I spent a few dollars to replace the battery in hopes that it would work better, but it didn't. The seller was very nice and took care of the problem.
