Rechargeable LED light. Suitable for attaching to phone/laptop/tablet/ipad/book. Never get left in the dark! With 3 brightness levels you can have lighting for any occasion. These are lithium rechargeable units. Don't fall in the trap of buying cheaper versions which require batteries and are not rechargeable.
The lamp shines strongly, on the iPhone X keeps perfectly. Only inside is something cockroach, I do not know or it's normal or something broken... Packing is normal. The lamp is bad, charges very long and lasts 5 minutes, I do not know what you need to make a photo in 5 minutes and then you need to put again on charging, the seller ignored my messages...!
