Both sides of it heat up and it only has 1 button so not difficult to use

There are three leds on the side of the device to both monitor charge levels and see control the temperature level of the handwarmer

It gets up to a warm but not burning level although if you want a real jolt of heat you can always keep it in the included pouch inside a pocket so the temperature builds up a fair bit above what would be a normal sustained heating level

The powerbank functionality works although im only likely to use it in emergencies given a have a number of other powerbanks which support fast charging standards whilst this is just a bog standard output

Soon opening the box you find the “pebble” in a tacky plastic bag
