Capacitor Specifications

Capacitance (farads)
Capacitors are rated in farads, and at times microfarads or millionths of a farad. The more farads the capacitor is rated at, the more electrical charge (and wattage) the capacitor will hold. Capacitance is defined as the property of storing an electrical charge between two separate conductors.
10 farads
LCD Meter Display
Displays the current voltage and/or other specification on an LCD readout.
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
10 AWG
Maximum Output Gauge Size
This number refers to the maximum size of wire that will fit into the output connector(s) of the capacitor, battery terminal, or any other connector with an wire output.
1/0 AWG
Built-In Distribution Block
A built-in distribution block simply means that the item includes a distribution block. The built-in distribution block will split the single power input into a multiple power output.
Primary Color
This is the main color of the item.
Secondary Color
A color that compliments the main color of the product.
This is the color of the illuminated LED lights on the unit.
