This charger is a little larger than my last charger, but it is 2x the size. I tend to forget to charge my charger so the larger the better. I leave this charging overnight when I do charge it and it will charge my device when I am on the go. I keep it in my purse in case of emergencies. Having a four year old phone, my battery isnt the best, but this keeps me from having a dead device. Highly recommend.
