I had never seen anything like this so I was surprised at the weight of it. All other battery packs I have seen are cylinder, this one was nicely shaped rectangular similar to a Smartphone styling. It’s not super heavy but it is a battery so has a little more weight than a phone. It’s not something you would carry around in your pocket but maybe in your purse or bag. I found this very convenient for charging my phone and tablets. The built in cord was a great bonus. No need to have lose cords hanging off it unless you want to charge 2 devices at once which in this day and age is a very common thing to have multiple items. I love the green colour it is very refreshing and just pops with the white. I took this to the beach where we used it to charge the phones when playing music all day it was great. Other people had to go back to their cars and charge devices or others turned theirs off but we were still running on many more charges left. This power bank will definitely be going on vacation with us to the Caribbean so we can charge our devices and not have to worry about finding an outlet or leaving our phones in the room to charge so we will have lots of battery for pictures, videos and music. I highly recommend this power bank to anyone who needs to charge their devices on the go or just have some more freedom on where they charge their devices. I received this item at a discounted price in exchange for an honest review.
