2V system technology

It has a long lifespan, doubling that of traditional 4V/4AH lead-acid batteries.

② More power-efficient and durable, it saves twice as much power as traditional 4V/4AH lead-acid batteries of the same volume.

③ It is more environmentally friendly. Under the same current usage, 2V consumes twice as much energy as 4V.

Two: Touch buttons

① Capacitive inductive keys: Easy to operate, fast and quick, and not prone to wear and tear over long-term use.

② The key structure adopts an overall isolated design. The keys are controlled by an internal chip sensing method. Its key plate structure is waterproof, anti-corrosive and oil-proof, and its service life is more durable than that of traditional mechanical keys.

Three: PET key panel

It features easy cleaning, water resistance, oil resistance and anti-corrosion, and is not prone to deformation even after long-term use.

Four: Potting the motherboard

Features: waterproof, moisture-proof, oil-proof, insect-proof, anti-false soldering, anti-oxidation, durable.

Five: ① The rubber ring of the vertical pole after folding can reduce the shock of the instrument. ② The folding connection seat adopts a triangular reinforced support frame, which is firm and durable.
