Query: Bought to keep in car

I bought this to keep in my car for emergency use. When I needed it the batteries had lost their charge, it had been over a year so that is understandable. I had a long USB cable in my car and a USB port so I plugged it in - worked great. Why 1 star it ? It will not turn off turn off. If any one can suggest a light that would better fit my needs please let me know. Note: After a full charge the on off function started working so moving forward I will charge every month
