I didn't know there is battery case for iPad even one year after I got my tablet. I have a battery case for iPhone, that provides quite long extra standby time. So that urges me to buy another for my tablet because I always take it out and travel. Some one recommend me an iPad battery case, that make me a little excited because it looks great and with a 7000mAh battery capacity. This is the case Leather Case + 7000mAh Rechargeable Battery for iPad CBT-33679 - TinyDeal But I am still hestating, this price is high, I can buy a good power bank with the money. So I want to ask anyone out there have recommendations for me, do you have battery case for iPad? Let me know, thanks inadvance.
