MaxiCharger has been a lifesaver for me over the past 6 months. I travel to football matches regularly and has kept my battery charged all day and until i return home. The MaxiCharger is lightweight, durable and gives me an extra 120% so i don't worry about listening to music or taking pictures without my battery running out. There a two things that are great about this product. 1. That it is Apple certified. 2. That it is not that expensive compared to the other Apple certified battery cases. I would recommend this product to anyone who uses an iPhone and who wants something that is low-cost and a gadget that actually works all the time!
