    Quite heavy, definitely not for a pocket. More perfect for purses or bags.

    My android LG K51 smartphone is not suitable for the magnetic Engergizer. The second choice is the image shown above. The size, simplicity and the price, I found to be suitable for me. I keep the energizer in my glove compartment so when I forget to have my phone charged and need to use it while in the store, I just take my energizer into the store with me.
