I couldn't find this specific type online but from what I could gather from ones similar to this they typically sell for 40 to 80 dollars. If you're looking for a durable and reliable mobile phone charger that lasts a long time this is a great deal for you. Willing to bargain to on price but not by much since I consider this pretty cheap already.:)
Capacity: 10000mAh/3.7v
USB and wireless output: 5V
