I got a blinking red led light (it should be a steady red light - indicating that it is

To indicate that it's charging, the GEN Mini will show a solid red light on the front, and when it's fully charged it will be a solid green color, also on the front of the unit

Only two LED lights, Charging and Charged.

lights on it are a little dim...but works and charges from way down to full by generator at the lake in a tank of gas

and I checked on the charger and found that the main box was hot, no LED lights on and low voltage at the batteries

Works but lights keep flashing even after I purchased new battery.

Bright LED lights too.

and it appeared to have moisture built up in behind the led lights

Solid red lights when charging.

I love the four indicator lights for ease of mind - one quick glance into the engine

Looks cool when lit up along with my bling lights

easy to mount comes with everything, plugin cord is short but thats probably a good thing, red light for charging and green for done

lights on it are a little dim...but works and charges from way down to full by generator at the lake in a tank of gas

The LED lights are very visible

the bilge pumps (2) will kick on to pump the water out of the boat, which causes the red & green lights to go crazy, and the unit will stop charging

It gave no warning of failure, no smoke or odd lights or heat

Solid green lights when charged.

I like the pretty lights too.

Sent the first one back- bad indicator light.

it t keeps my batteries charged and ready for action.
