Liked the smaller version of Rush, because it fitted in my pocket. The latest verision is too large. I do not carry a purse any more.
Charges quickly and no complaints so far other than the charging tabs (usb-c, Apple, etc.) are way too easy to break. I’m not sure they came with enough extras. My 2 kids and I have each broken one already after only a few weeks.
Rush charge is the best for emergency use. How many times have you been away from a charging station and ran out of battery. I highly recommend having one for every member of your family in case of an emergency.
