Review on Candle Lighter with USB Rechargeability, LED Battery Display, and Safety Switch - Perfect for Candle, Cooking, BBQs, and Fireworks by Omar Malvo

This lighter works well. If the candle was previously lit, the lighter will light the candle immediately. When the wick is lit for the first time, it will take a few seconds for the new wick to ignite. The lighter makes a very high pitched squeak when you use the lighter. Depending on your hearing, you may or may not be able to hear it. (About half of my family could hear it). When I used it, it had enough power to light candles and experiment with a lighter. I don't know yet how long it will hold a charge between uses.
