The company behind the battery card that fits your wallet I wrote about is back with a better one, the pro version as they call it. It has three times the battery capacity making it able to fully charge most phones for twice the thickness. They also added an additional USB port and is considered to be the fastest power bank charger in the market.
I haven’t got my hands on one but I will very soon. I’m excited because even though this one doesn’t fit my wallet, it will easily fit my pocket and should be able to fully charge my phone once (3,000 mAh battery). Phones with a smaller battery like the iPhone 5 and Galaxy S5 should get up to one and a half charges before needing to recharge the Lithium Card Pro.[Source]
It should be available in Kuwait soon.
