Product Description:

Description:
Providing mobile power for your DIY projects has never been easier with the MH-CD42 Power DIY board!
This tiny board offers simultaneous charge and discharge, lithium battery protection, and a 4 level LED
indicator. Connect any kind of 3.7V Lithium battery to have a 5V output with current up to 2.1A.
When charging, the four-level battery indicator starts with one flashing LED, meaning the battery is less
than 25% full. After some time, 2 LED will lit up and the first one would stop flashing. That means your
battery is 25% to 49% full. Your battery is fully charged when all 4 LEDs are lit and not flashing.
In discharge mode, the same definition applies but in reverse.

Works good but have only tried it on fine setting.
Works good but should have an overall cap as seasoning gathers around the inside.

Great Value!
Color: Tall Set - Black White
Better than anticipated. These are sturdy and work very well. They came with a little funnel to fill, but easy enough without it. They are attractive, I keep on top my stove as I have room. Grind well.
