had these on sale for about $30 and I bought four or five of them. They come with a removable rechargeable battery, or you can put standard (or rechargeable) C- cells in them. The light is bright and a charge lasts a long time. They have both a USB-A and USB-C port for charging them (the C port will charge faster). There are four small blue LEDs by the on/off switch to indicate the status of the charge.
You can adjust the size of the beam by turning the lens part of the flashlight. I would prefer if it adjusted to a smaller beam, but it's okay.
