We have covered many iPhone battery extenders here in the past. BOLT happens to be quite special because it has its own wall charger. Bolt has a 3000 mAh battery so it can fully charge your iPhone twice. The device is compact and portable. Its wall prongs can be folded when you don’t need them. The fact that BOLT can be recharged easily is a huge plus. BOLT is up for funding on Kickstarter.
