You can hit the mode button and if it's in the room where you sleep they say, it will dim. I don't have that problem, and haven't really bothered pushing the buttons. This charger was purchased for my (2) 26650 batteries, and it works just fine and dandy. Easy to use. Pop the battery in head's up and away it goes. Nothing could be more simple.

SUPER fast shipping, item exactly as described. Very pleased!

A perfect product. Does everything you need it to do. And I fell in love with the slider. The only way this product could possibly be better is if it was also a battery it's self and charge stuff wirelessly. But hey I'm not complaining

Works great on different battery Sizes and Capacities. Details of Battery you are charging, Volts, Amps, etc. Highly recommended for a SAFE way to charge the new high tech Li-po batteries!

Working as design. The battery charging indicators are great reference.
