newegg.com offers the Energizer Protective Case with Built-in Battery for Apple iPhone 3G / 3GS, model no. AP1500, for $12.99. With free shipping, that’s $2 under our August mention (which also included a usable case, see below) and the lowest total price we could find by $7. It’s also the least expensive iPhone case we’ve seen with a built-in extra battery. This protective case features a built-in battery and has an LED battery life indicator light. It comes with a USB charging cable and provides up to four extra hours of talk time.
