Package included: 1 battery clip 1 X Battery thick wire 1x Certificate of Conformity 1 User Manual 1 X pure sine wave inverter Socket: universal type (commonly used in sockets in all countries/regions) -Peaks Power : 250W/300W -Rated power: 250W/300W Output frequency: 50Hz Input voltage: 12V Output voltage: 220V Output voltage waveform: Modified wave inverter Features: Compatible with high power electrical appliances, pure sine wave with full power and no virtual standard, 220V output is compatible with a wide range. USB output, 5V 1A/2.1A supports a variety of digital products. Intelligent silent fan, intelligent temperature control and mute, strong heat dissipation reduces the internal temperature, and the use is more durable.a Equipped with pure copper wire core power cord, alligator clip wire + Car charger wire, thick pure copper wire core, low energy consumption and stable transmission. 1000W inverter, continuous power is 500W, starting power is 1000W. 1600W inverter with continuous power of 800W and starting power of 1600W. 2000W inverter, the continuous power is 1000W, the starting power is 2000W. 3000W inverter, continuous power 1500W, starting power 3000W. The 4000W inverter has a continuous power of 2000W and a startup power of 4000W. It is 2000W, can carry 1000W ordinary resistor, 3000W can take 1500W electrical appliances, such as: computer, TV, fan, light, these are can take resistor. Nevertheless, the starting power of inductive load appliances is 3-12 times, the continuous power meets the conditions, and the starting power must also meet the conditions to drive. Such as If the battery is 12V / 60AH, can 2000W inverter and 500W hard drill be used? 1. First look at the maximum battery charger: 12 * 60 * 0.8 = 576W, >500W. 2. Determine whether the electrical appliance is a resistance electrical appliance or an induction electrical appliance: the hand drill is an induction electric drill. 3. The continuous power of hand drill is 500W, and the duration of 2000W is 1000W, >500W. The starting power is generally about 3 times (the starting power of Dove appliances is different), so 500W X 3 = 1500W, the starting power of 2000W inverter is 2000W, >1500W Therefore, 500W hand drill can be used with 12V / 60AH battery and 2000W inverter. Other appliances can also be judged in this way. If you encounter problems and do not understand the operation, you can also consult customer service, thank you! How to choose the right battery for the inverter

Working time =U (voltage payment) x I (battery capacity) x 0. 8 × 0.9 ÷ Electricity Example: 12V 50AH battery with 220V 100W bulb Working time =12Vx50AH×0.8×0.9÷100W=4.32 (hours) Note: 0.8 is the battery discharge coefficient (constant) 0.9 is the conversion efficiency of the inverter (constant)
