Ok product, need frequent recharging

the product build quality is good but the single charge doesnot last more than 15-20 mins. you need to keep spinning for continuous use, which is irritating at times.

Bad Option

The brightness goes down very soon, requires a lot of turns to even work in a basic, not recommended

Low battery level

Low battery capacity


Cheap and good

Useful indeed

Only complaint is that it doesn't have an indicator to show full charge.

Tengo tres. Uno en las maletas de la moto otro en la guantera del coche y otro en casa. Más de una vez me ha salvado de un apuro incluso si me olvido de recargarlo le doy un poco de carga y hace su función y si se que lo voy a usar con anterioridad lo pongo a cargar un rato
