    Was great. Came in real handy. Charged my stuff like a champ. Then it just stopped taking a charge. Now it's a brick. Energizer says they licensed a company to make them, contact them. The company says take it to the store. I'm gonna try but I'm not hopeful. I bought it March 22nd so the return period is over.
