I have been using power banks for years and I must say that the one I got from Powerstick.com is by far the best. It has a sleek design and the battery life is amazing. I can charge my phone multiple times before needing to recharge the power bank. The customer support team at Powerstick.com is also fantastic. They were very responsive and helped me choose the right power bank for my needs. Highly recommend their products!
