Description: Input voltage range: DC 12V (11V-14V) Output voltage: AC110V or 220V Output frequency: 50HZ USB output current: 5VDC or 2.1A Output waveform: corrected sine wave Overheating protection: 65 Low power cut off: 10v High power cut off: 15v Unloading current: less than 0.9A Conversion efficiency:>90 percent Specifications: 1. [High power output]: It is compatible with all kinds of electrical appliances, adopts intelligent adaptation technology, and widely supports most digital and household products on the market 2. [Buzzer reminder]: When the inverter is used, when the power supply battery is insufficient and the voltage is not enough, the inverter will send out a drip warning to protect the electrical appliances from being damaged due to insufficient voltage 3. [Pure copper core power cord]: elastic alligator clip, thickened pure copper core, low energy consumption, stable transmission 4. [Thickened aluminum alloy shell]: excellent heat dissipation comes from the design and materials. The concave convex surface designandaluminum alloy shell effectively improves heat dissipation. The thickened aluminum alloy shell greatly improves heat dissipation and compression resistance 5. [Intelligent digital display large screen]: real-time display of output current or voltage Package Included: 1 x Inverter 2 x Battery clip 1 x Cigarette lighter plug 1 x Instructions
