I recently purchased a maxx power bank for my phone xperia SP. I expected it to be charging my phone for atleast one time. But to my surprise the power bank did not last for once. I recharged it because I thought it was already out of energy. But again it disappointed me. It couldn’t even charge my phone once. The battery drains out quickly and I had to go without my dead phone.
I would not recommend this product to any one.
