Title: Works fine!
Review: I purchased this product to blow up an air mattress while out camping at Cook Forest, PA. It worked fine with the two large air mattresses. It does state to not use it to charge devices such as cell phones. I used it for my cell phone and it did charge it but the phone started to act up a little. The phone is working fine now so I'm not sure if the problem came from the inverter or not.
Is this product review negative?
