4 rechargeable 18650 2600mah batteries with and included 2 bay charger (usb powered) with cable. All tucked nicely in a protective foam cut out for everything to fit snugly in place inside a box nice enough for gift giving and shipping purposes.
My son in law and grandson will love these for hunting and fishing and all the other outdoor activities.
This is a great item to have around the house for emergencies. The 5 settings include 3 brightness levels, an intense strobe and an s.o.s. feature making this the must have for anyone. I'm very happy with mine.
