Super spacer

The invention discloses a super spacer which belongs to the vehicle-carried electric appliances and is used for compensating the instant decline of battery voltage. The super spacer mainly comprises a waterproof transparent shell, a liquid crystal display part, a single chip, a capacitor matrix and a waterproof lead; the liquid crystal display part, the single chip and the capacitance matrix are integrated on a circuit board and embedded in the waterproof transparent shell; the waterproof lead is connected with a vehicle lighter; and the capacitance matrix comprises a power compensation part and a hierarchical filtration part. The super spacer integrates the functions of instant power compensation, real-time voltage display and hierarchical filtration, and has the characteristics of convenient use, simple structure, stable work and the like.
