Perfect. Exactly what I wanted. I bought this because the price was right, it's a cute color and because I wanted to have a backup portable charger for the long days where I don't seem to get a chance to charge my phone.
It's a sturdy charger and came with a charging cord. I've used it a dozen times already; once was at least 3 weeks after charging it. It held a charge well and quickly charged my cell. I like that it has a light to show you what level of charge it is at. Handy little sturdy charger, I love the square design. - I'd buy Jackery products again.
